Water tube steam boiler manufacturer in Philippines

A watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam.

The heated water then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In some services, the steam will reenter the furnace through a superheater to become superheated. Superheated steam is defined as steam that is heated above the boiling point at a given pressure. Superheated steam is a dry gas and therefore used to drive turbines, since water droplets can severely damage turbine blades.

Water-tube boilers for sale in Philippines differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress , it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be tolerated for the same stress.

Water tube boiler can be available for many fuels such as oil ,gas ,coal, biomass.Water tube biomass steam boilers in Philippines are widely concerned by investors in food process, textile, slaughter house. With independent imported and exported right, ZG has exported hundreds of water tube boilers with reliable quality and suitable water tube boilers price to Philippines, enjoying a good reputation.

Two Reasons Why Biomass Fired Boiler Leakage

As energy price is increasing and pollution is more and more serious, more enterprises seek green and environmental protection fuel, biomass as the ideal energy is to replace some fossil fuels to be used in industrial boilers.

A green biomass fired boiler is a high efficient and environment-friendly product that can easily burn shaped biomass fuel or both pure and mixed coal with its economizer in the rear. Fuel: Biomass fuel forming; rice husk, bagasse, coconut shell, straw, coal and biomass blends


Biomass fired boiler might occur leakage that affect its efficiency. Here are the Two Reasons Why Biomass Fired Boiler Leakage.

Oxygen corrosion
For the water tube biomass fired boiler pressure parts,the water side is mainly electrochemical corrosion,the fire side (or flue gas side) is mainly chemical corrosion.The oxygen corrosion belongs to electrochemical corrosion, it is mainly caused by the dissolved oxygen in water.At room temperature,the dissolved oxygen concentration is about 9.1mg / L,according to the GB1576-2001 "industrial boiler water quality" requirement ,the rated steam pressure should not be more than 1.0MPa,the dissolved oxygen concentration should not be more than 0.1mg / L,otherwise,it is likely to lead to metal corrosion.

Chlorine Corrosion
The chlorine ion exchange will cause high rate of metal corrosion,which is due to that the chloride ion radius is small,and it is typically activated anion,it is more active when the oxygen exists.With the operation of the boiler,if the boiler water salinity increases,the concentration of chloride ions rise constantly,there will be more deposits at the bottom of the boiler,in smoke pipe and the water cycle weak areas.

Cost of fire tube boiler

ZG Boiler is fire tube boiler manufacturer with 70 years history, providing good quality and price for boiler.

What is fire tube boiler
The exhaust gas which is produced after fuel burst following through fire box or fire tube heat the fire box or water and steam mixture, which is called fire tube boiler. And the fire tube boiler is also called shell boiler. A little cylinder, pipe (what is called fire tube), other shell body (what is called boiler furnace) compose of the basic structure of the big cylinder in the fire tube boiler. The interlayer which is formed by fire tube and big cylinder fills water, the fire tube and the boiler furnace containing flame and exhaust gas as burst chamber and funnel.

Advantages of fire tube boiler
The advantages of fire tube boiler are following. It has big volume, strong heat storage capacity and simple structure, installation and operation. But the fire tube boiler has weak evaporation intensity low vapor pressure. The working conditions are bad because the boiler shell and internal components are heat up directly. Besides, the strength of boiler shell is weakened because of trapping and large storage. The vapor heating surface which lies out in the cylinder is called shell boiler or fire tube boiler.

Cost of fire tube boiler
The use and maintenance cost analysis of the fire tube boiler will be introduced in detail in the following. First, the fire tube boiler is not sensitive to the water quality. Conventional resin softening is pretty god without chemical medicine. Second, the structure of the fire tube boiler is reliable, and the operation and maintenance are convenient with long life. It has not booster hidden danger. Third, the boiler manufactures in China almost produce the fire tube boiler, the burners of which are Europe and America famous brands in common. And the purchase of fittings is convenient and fast, just because of this, the user cannot be strict by the fire tube manufactures.

Fire tube or water tube steam boilers in India

Steam boilers have a large market in India, because the biggest developing country, India is developing rapidly lately and amounts of large heavy equipment like industrial boilers are essential in country development. We are a steam boiler supplier and still have cooperated with Indian companies for a lot of times before.

Industrial steam boiler structure
An industrial steam boiler for sale is usually a one contains water along with a flame powered by oil, coal or gas. The boiler transfers heat in the flames for the water vessel, thereby turning water into steam. This steam exits the vessel a different option . pipe and is also transported to an alternative location where quite a few to clean up, to power equipment, to deliver heat or for a great many other functions. A closed boiler way is one in which totally with the steam is returned towards vessel available as water and reused. Closed boiler systems are efficient and fewer expensive to control. However, some industrial processes contaminate the steam and forestall it from being reused.

Fire tube or water tube steam boilers in India
There's 2 main forms of boilers for sale in India: fire tubes and water tubes. From the fire tube boiler, heat is directed through metal rods that go through the center of the stream vessel. The rods are arranged in banks hence the heat can pass through the vessel oftentimes before escaping over the chimney. The hearth tube system exposes the lake towards maximum level of heated surface plus affords the maximum level of water safe-keeping. Inside a water tube boiler, the warmth is directed through metal rods nearby the not in water vessel. Water tube boilers are vertical and discover the capability to create more units of steam each hour and as well provide less water storage than fire tube.

What people can benefit from waste heat recovery system boilers

A recovery boiler is a power plant subsystem used to capture energy that would otherwise be lost in waste products that were not completely combusted. This energy is recycled to the primary energy generating system to produce more power. For this reason, this equipment may alternatively be referred to as a heat recovery boiler or as a waste heat recovery boiler. The main requirement for its use is that the system’s waste products have sufficient recoverable energy to drive the primary power generating equipment.Waste Heat Recovery Steam boilers may be used in the power systems for a variety of industrial equipment.

Waste recovered for further combustion in a recovery boiler is usually a gas, a liquid, or a combination of the two. Processes generating these types of wastes include metal refineries, petrochemical processing plants, and other industrial plants operating at high temperatures. Solid material may also be used, though this is less common. The most notable example of solids used in recovery boilers is in papermaking.

Benefits from sinter-cooler waste heat recovery system
Direct benefits: The recovery process will add to the efficiency of the process and thus decrease the costs of fuel and energy consumption needed for that process.
Indirect benefits:
Reduction in Pollution: Thermal and air pollution will dramatically decrease since less flue gases of high temperature are emitted from the plant since most of the energy is recycled.
Reduction in the equipment sizes: As Fuel consumption reduces so the control and security equipment for handling the fuel decreases. Also, filtering equipment for the gas is no longer needed in large sizes.
Reduction in auxiliary energy consumption: Reduction in equipment sizes means another reduction in the energy fed to those systems like pumps, filters, fans,...etc.

How to solve air leakage in autoclave

It is very important to ensure that all of the trapped air of a steam autoclave is removed from the autoclave before activation, as trapped air is a very poor medium for achieving sterility. Steam at 134 °C can achieve in three minutes the same sterility that hot air at 160 °C can take two hours to achieve.
Methods of achieving air removal include:
Downward displacement: As steam enters the chamber, it fills the upper areas first as it is less dense than air. This compresses the air to the bottom, forcing it out through a drain which often contains a temperature-sensing device. Only when air evacuation is complete does the discharge stop. Flow is usually controlled by a steam trap or a solenoid valve, but bleed holes are sometimes used, often in conjunction with a solenoid valve. As the steam and air mix it is also possible to force out the mixture from locations in the chamber other than the bottom.
Steam pulsing: air dilution by using a series of steam pulses, in which the chamber is alternately pressurized and then depressurized to near atmospheric pressure.
Vacuum pumps: a vacuum pump sucks air or air/steam mixtures from the chamber. (Explained here)
Superatmospheric cycles: achieved with a vacuum pump. It starts with a vacuum followed by a steam pulse followed by a vacuum followed by a steam pulse. The number of pulses depends on the particular autoclave and cycle chosen.
Subatmospheric cycles: similar to the superatmospheric cycles, but chamber pressure never exceeds atmospheric pressure until they pressurize up to the sterilizing temperature.

Coal quality importance in coal fired hot water boiler

20 ton coal-fired hot water boiler as a relatively wide used boiler form, can be used for winter heating, power generation,provide hot water in processing. The coal quality is very important, which is related to the normal operation of the fuel and the combustion efficiency of the boiler. The following is ZG Boiler analysis of coal quality importance in coal-fired boiler .

According to well know boiler manufacturer ZG, when the coal quality in boiler furnace has big difference from the coal boiler designed and verification coal quality, it may bring the following adverse impact on the boiler flame-out and auxiliary equipment:

1.when the 20 ton coal fired boiler coal quality is poor, boiler ignition and operation of conditioning will be tough, hard to extinguish, easy to flame-out, seriously affects the boiler outlet temperature standards. Easy coking in furnace, convection tubes, economizer, air preheater and other heating surface will be badly worn and easy to fouling, boiler air resistance increases, finally affects the thermal efficiency of the boiler.

2, when the sulfur content of coal quality is large, easy to cause water wall high temperature corrosion, the boiler backpass, economizer, air preheater, etc. produce low temperature corrosion, causing boiler tube explosion and affecting safe operation of the coal fired hot water boiler.

Therefore, when choosing 20 ton coal-fired hot water boiler, the coal quality needs to pay attention and  choose according to the actual design and local fuel supply. More information about boilers can also consult ZG Boiler engineer, hot line 86-371-86062323.

Why should ensure safety of pressure equipment boiler

Boilers, storage tanks and other pressure equipment are potentially dangerous objects. They contain large amounts of energy while operating. The energy is released instantaneously if they fail and the results are devastating. When water changes from liquid to steam, it expands 1,600 times its original volume. In other words, one cubic foot of water instantly converts to 1,600 cubic feet of steam. A small industrial boiler having a volume of 10 cubic feet and operating at a pressure of 100 psi has an explosive equivalent of 2,278 grams.

In order to ensure the continued safety of pressure equipment, it is inspected by qualified commissioned inspectors on a periodic basis. The purpose of the inspection is to make sure accidents do not happen. Since inspections are a snapshot in time and can only tell how safe the vessel is at the time of the inspection, there is an implied duty on the owner/operator of the vessel to keep it in safe and proper working order.

measures to lower hot water boiler electricity consumption

Responding to the call in the national energy and environmental protection policy, hot water boiler, in order to meet environmental requirements, using natural gas, fuel oil and biomass pellet fuel. To meet up with the vitality requirements, some begin to try and reduce power consumption in hot water boiler.
ZG to be a well-known manufacturer of boiler brands, so that you can reduce the usage of electricity, we adopt the mechatronic control devices and programmable logic controller (PLC) joint control. The boiler engineer of ZG increases the following measures:
1, good room heating hot water boilers heat load to view power: Different housing structure, the surrounding height, lighting area, room location, the thermal load takes a different approach, ZG 1 ton corner tube hot water boiler heating area can be 6000- 8000 square meters.
2, the control temperature hot water boilers run in the evening: sleep at night, and we don't desire a high heating temperature is usually appropriate to reduce the heating temperature by adjusting the radiator thermostatic valves can freely adjust the temperature on the room, we could the deputy bedroom, storeroom, etc. not frequented room temperature thermostatic radiator valves to scale back, to help you to also save operating costs of heating period.
3, adjust water temperature difference: Perfect for hot water boiler return water temperature should be used 4-5 ℃. Proper adjustment with the temperature difference between supply and return water can help the heat transfer coefficient, so efficiency is high, can significantly reduce operating costs over the heating period.

Whether Steam or Hot Water Boiler should be used

 The primary purpose of the boiler is to supply energy to the facility's operations – for comfort heating, manufacturing process, laundry, kitchen, etc. The nature of the facility's operation will dictate whether a steam or hot water boiler should be used.

Hot water boilers
 Hot water is commonly used in heating applications, with the boiler supplying water to the system at 120°F to 220°F. The operating pressure for hot water heating systems usually is 30 psig to 125 psig (hydrostatic). Under these conditions, there is a wide range of hot water boiler products available. If system requirements are for hot water of more than 250°F, a high-temperature water boiler should be considered.

Steam boilers
Steam boilers are designed for low-pressure or high-pressure applications. Low-pressure boilers are limited to 15 psig design, and are typically used for heating applications. High-pressure boilers are typically used for process loads and can have an operating pressure of 16 to more than 1,000 psig. Most steam boiler systems require saturated steam, which means the water and the steam in the vessel are at the same temperature.
