circulating fluidized bed boiler smoke ventilation system
Zhengzhou Boiler Co., Ltd. was founded in 1945, 70 years history has made the leading boiler manufacturer and exporter in China. This article is mainly about circulating fluidized bed boiler smoke ventilation system. Balanced ventilation CFB boiler furnace pressure zero set in the furnace exit. Circulation of materials within the circulating fluidized bed boiler by the blower (including one or two fans), the Roots blower and induced draft fan to maintain. From a fan out of the air by an air preheater heated air into the furnace at the bottom of the primary air chamber, wind through the cloth hood panel of the bed material flow and the formation of solid circulation upward through the furnace; secondary air by the second Air preheater heated air to the furnace side of the argument, from the bottom of the furnace wall into the furnace before and after the combustion chamber; the second road on both sides of the secondary air duct from the boiler leads to an air duct to the blast furnace, and then trail leads from the wind 3 coal drop pipe branch pipe to the wind as the broadcast of coal. Carry out the furnace flue gas of solid particles, through import of flue cyclone, respectively, into the two tangential cyclones. In the separator, coarse particles separated from the flue gas, and gas flow through the tube into the flow splitter center shaft, flue gas cooling by convection heating surface, through the tube into the air preheater flue gas dust removal Composition of fine particles, and finally, by the suction fan into the chimney, and into the atmosphere. biomass fired cfb boiler http://www.zgboilers.com/Products/biomass-fired-cfb-boiler.html

what to do with oil fired steam boiler
oil steam boiler is heated oil as fuel to generate steam for industrial boilers, by fuel category, there are still fuel steam boilers, coal-fired steam boiler, biomass steam boiler, the principle is the water temperature high pressure to form a thermal power generation , for the production of life energy use.
Steam boiler in operation, will always be a water shortage, water scarcity will cause the flue pipe leaks ranging from heavy equipment can cause deformation, or even explode. According to statistics, accidents caused by lack of water boilers account for fifty percent of major incidents, we can see that there boiler water, proper and timely treatment to avoid unnecessary casualties and economic losses.
ZG industrial steam boiler expert to solve this problem, with many years of rich experience, for mild and severe shortage of water were given to different solutions.
The degree of water shortage can be called to determine if there is water in the water level occurs, it indicates a slight shortage, if there is no water there, it indicates a serious water shortage.
When slightly dry. When there is a slight lack of water, you should open the bypass damper, reducing the furnace air flow, lower oil steam boiler evaporation, reduce boiler load, manual water to the steam drum.
When severe water shortage. If the steam boiler in a state of severe water shortages, this time to an emergency shutdown, small flow of water, should not blind a lot of water, so as to avoid high temperature boiler rapid cooling large temperature difference, a huge thermal stress, boiler parts from being damaged.
ZG oil steam boiler manufacturer also solemnly remind you that in the boiler operation, be sure to do surveillance, real-time recording of data, arrange the investigation, so that not only can guarantee the normal operation of the boiler safety, eventually working efficiency can be improved.

gas fired vacuum hot water boiler for sale
Gas fired vacuum hot water boiler for sale is widely used in power generation, pharmaceutical industry, refineries & petrochemicals, cement industry hospital, food industry, pulp & paper industry, beverages industry, textile industry, chemistry industry, cleaning industry, automotive industry, thermal powerhouse, hospital, etc.
High efficiency and saving energy: Using vacuum hot-water boiler technology to produce boiler operating inside a vacuum state, Low boil, the heat of transformation of vaporization (latent heat), heat transfer, effectively improve the thermal efficiency, high temperature transfer performance, our bodies of boiler use design of wet back with three get back to effectively increase the radiation and convection heat transfer area. Thermal efficiency of boiler can be up to 91%.
High safety and reliability: Vacuum operation unit, hot coal in vacuum state, there is no danger of expansion and explosion. Having constant thermal coal water within the furnace could not make any danger of ingredient. Multiple automatic protection devices in ZG gas fired vacuum boiler have more safety than other boilers.
No corrosion and scaling, long service time: Using stainless-steel thermal exchanger makes thermal coal operate inside a closed state. No corrosion and scaling make its service life twice longer than ordinary boiler, and this can be used for 2 decades.
Variety model, one model many uses: There several types for customers to select for example vertical type, horizontal type, oil-fired type, gas-fired type, water pipe, smoke pipe,
Small size as well as simple installation: Modular design, high performance heat transfer components, small size help it become simple to transport. In a tiny space, multiple units can be used parallel.
