Europe and South East Asia (SEA) followed this region in terms of installed capacity for CFB boilers. India was a relatively small segment of the CFB boiler market in 2011 but is expected to witness substantial growth over the forecast period owing to the rapid development of the country. North America has comparable installed capacity for CFB boilers but the growth in this region is expected as an outcome of up gradation of old CFB boilers.


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.

Four questions must be considered when you choose steam boiler

Steam boilers have been a useful energy source for several centuries. With a simple setup, a steam boiler combines water and heat to create pressurized steam that is easily manipulated for indoor heating, powering engines and more.
Four questions must be considered when you choose steam boiler:
First: the problem of fuel.
The choice of fuel is certainly to choose the most economical one, we all know that fuel is so expensive, for the company, the cheaper the better. As for what kind of boiler fuel should be determined, according to your actual production requirements. Generally speaking, if the production is small , I suggest you choose to use fuel wood boiler, which is relatively more affordable. Because in addition to the cost of the product itself is cheaper than other boilers, what matter most is that its later production cost than other fuel boilers is much cheaper.
Second: the working pressure of the boiler, rated evaporation parameters.
The working pressure of the steam boiler, rated evaporation parameters must be combined with your companies’ actual production. Pay attention to choose it, for if you choose a bigger than actual use, it will absolutely cause waste, or if smaller, it will not enough for production, this point must be clear.
Third: clear the local environmental requirements.
To make clear the local environmental requirements is important. Some different cities have different requirement. Some places may not allow a coal or wood -fired boilers; some places may only allow the gas or electric steam boiler to be used.
Fourth: the installation of steam boiler.
The installation of the boiler is also a science and demands professional persons. Find a reputable and qualified companies will be much better. ZG Boiler as the A grade and ASME boiler manufacturer can give you a great and full direction installation guidance, and we have the best after-sale service.

How an industrial boiler work well


Industrial boiler has played a huge role in industrial production,such as the fertilizer plant can use industrial steam boiler for evaporation.The operation of industrial boiler can be seen as the cyclic process which produces steam or hot water by heating the water in the furnace,this text will analyze that in the following sections:

The operation of industrial boiler includes three processes,the furnace process, the heat transfer process,the inter-boiler process.The furnace process is the process producing high temperature flame and flue gas by burning the fuel in the furnace to change the chemical energy into thermal energy.The heat transfer process is the process about that the high temperature flame and flue gas transfer the heat to the boiler water through heating surfaces.The inter-boiler process is the process outputting the steam or hot water thorough the water in the boiler absorbs heat to raise its temperature.

Measures to reduce the coal fired boiler heat losses

ZG boiler is a eminent manufacturer of industrial boiler China, and we provide good quality coal fired boilers to our clients. But heat losses might occur, the followings are some measures to help reduce coal fired boiler heat losses.

Choosing the appropriate coal

The quality of coal has a grate influence on the service life of coal fired boiler,the proper coal includes the following aspects:the ash content of coal is not less than 6%,the ash melting point should be over 1250 ℃, the coal particle size should be moderate,the detritus content below 3mm is not more than 30%, the largest particle should not exceed 40mm.

The reasonable layout of furnace

In order to reduce the combustion loss,the full combustion of fuel is needed,which can be achieved by strengthening the mix and stir of space air,it is completed by the cooperation of front and rear arches and the secondary air.

The reasonable air distribution

The air is indispensable to ensure combustion,the reasonable air distribution makes a great difference to the energy conservation of coal-fired boiler,the air should also be reasonably distributed along the grate length and width direction.For example,ZG coal-fired boiler adopts the way of air inlet in both sides,longitudinally arranges six air chambers along the grate,each air chamber has air regulating devices to adjust the air volume,which can achieve the best effect of adjusting the combustion.

what do you know about how a CFB boiler work

For the Circulating Fluidized Bed combustion has given boiler and power station operators a larger flexibility in burning a variety of coal as well as other fuels. More enterprises choose the CFB boiler in their industries, then do you know how the CFB boiler works?


Fluidized Bed
At the bottom on the boiler furnace there is a bed of inert material. Bed is the place the coal or fuel spreads. Air supply is from in the spare room at ruthless. This lifts your bed material and also the coal particles and keeps it in suspension. The coal combustion takes place in this particular suspended condition. This can be the Fluidized bed.

Special design from the air nozzles at the end with the bed allows airflow without clogging. Primary air fans provide you with the preheated Fluidizing air. Secondary air fans provide pre-heated Combustion air. Nozzles inside furnace walls at various levels distribute the Combustion air from the furnace.

Circulation of the CFB boiler
Fine particles of partly burned coal, ash and bed material are carried along with the flue gases towards the upper aspects of the furnace and right into a cyclone. From the cyclone the heavier particles separate from the gas and falls towards hopper on the cyclone. This returns for the furnace for recirculation. And so the name Circulating Fluidized Bed combustion. The new gases through the cyclone pass to the heat transfer surfaces and walk out the boiler.


Bed Material of water tube CFB boiler
First the bed material is sand. Some portion is lost in the ash throughout the operation this also must be made-up. In coal fired boilers the ash from the coal itself may be the makeup material. When firing bio fuels with minimal ash content sand may be the makeup bed material. For high Sulphur coals Limestone addition to the bed material reduces SO2 emissions.

we have many CFB boiler projects in different fields, http://www.zgindustrialboiler.com/project/20t-cfb-steam-boiler-for-textile-factory.html
