The DZL chain grate coal fired steam boiler produced by ZOZEN adopts advanced manufacturing technology, the grate is reasonable in distribution, the combustion chamber is large, and the coal type has strong adaptability. It is suitable for all kinds of bituminous coal, anthracite and mixed coal, so that all kinds of coal can be fully obtained. Burning.
The thermal efficiency of the boiler can be as high as 85% or more, and the effect of smoke and dust removal is also very good. The water cycle is simple and safe to use. Lump stoker grade coal is fed from the coal bunker to a hopper and metered by the stoker feeder onto the boilers moving grate. The coal is suspended on the moving grate and burns with air fed from below until combustion is completed. The coal ash drops from the front of the grate into an ash pit below the grate.
DZL chain grate coal fired steam boiler adopts high-temperature separation circulating fluidized bed combustion technology. The CFB mode of fluidization is characterized by a high slip velocity between the gas and solids and by intensive solids mixing. The intensive solids’ mixing insures adequate mixing of fuel and combustion products with combustion air and flue gas emissions reduction reagents.
Coal fired steam boiler are three pass fully wet horizontal smoke tube industrial boiler with internal furnace ash drop at the rear side of furnace to remove the ash. Capacity 300 kgs/hr to 6,000 kgs/hr. 3 TPH above will have double integral furnace for more grate area better combustion of fuel.
Coal boilers are commonly used to heat water and create steam for energy production. Coal-fired boiler efficiency can often provide lower operating costs in comparison to other fossil fuels almost 75% less than oil or natural gas. Coal, when properly handled and combusted, is one of the cleanest fossil fuels available today.
Chain Grate coal fired steam boilers have many types,you can choose according to your needs.Chain Grate boiler is mainly composed of upper and lower drums ,convection tubes ,water-cooling wall tubes,down pipes and headers.with fast,time-saving,compact structure,small footprint,etc.and it has high combustion efficiency,lower pollutant emission.
ZOZEN is an internationally renowned manufacturer of industrial DZL chain grate coal fired steam boiler.The chain grate coal fired boilers are widely used in industrial heating, electric power, public heating and other fields,too.No matter what industry you are engaged in, ZOZEN will be able to help you.
