Industrial Coal-fired boiler is refers to the combustion of coal, coal heat after conversion, to produce steam or hot water. ZOZEN boiler can produce circulating fluidized bed coal boilers with a thermal efficiency of more than 82%.
Coal-fired boiler is mainly classified according to purpose, it is divided into coal-fired hot water boiler water (supply), coal (heating and bathing) hot water boiler, coal fired steam boiler steam (supply), coal oil heat boiler (such as cooking and drying).
As the forerunner of environmental protection boiler suppliers, ZOZEN boiler has mastered the trend of the industry in real time, combined with the advanced technology and experience at home and abroad to truly produce products in line with the era of environmental protection. At present, the coal-fired boiler system built by ZOZEN Boiler has been shining in all walks of life with its excellent product performance and environmental protection advantages.
How a industrial coal-fired boiler works
1. The horizontal coal-fired hot water boiler is a single boiler tube vertical structure, the left and right sides of the furnace are equipped with water wall pipes, and a wing flue is formed. The threaded smoke pipes are arranged inside the boiler tube, and the movable grate with little coal leakage is adopted, which is reasonable in structure, high in thermal efficiency, and greatly saves energy consumption.
2. Horizontal coal burning atmospheric steam boiler, hot water boiler, gas fired boiler, oil fired boiler, coal fired boiler, energy saving and environmental protection boiler adopts single boiler barrel longitudinal arrangement of three-return water and fire tube structure, dense light tube water cooling wall tube on both sides of the furnace, reasonable and compact design structure; The heating area is large, the flue gas flow is long, the heat transfer effect is good, the exhaust temperature is low, so the thermal efficiency is high, the operation cost is low, the use is more economical.
3. Vertical coal-fired boilers and hot water boilers are equipped with a water-cooled bent tube structure in the furnace chamber, surrounded by furnace bile, with large heating area, high thermal efficiency, energy saving and consumption reduction; The shell adopts elliptic head, the grate adopts cast iron round grate, which is durable and long service life.
4. Horizontal coal-fired boiler, fuel on the fire grate combustion, the flame through the low wall to the combustion chamber, the state from the combustion chamber state through two flanks form before the flue to smoke box, again by smoke tube bundle to the smoke chamber, then northwards by induced draft fan through the chimney discharged into the atmosphere, not only can prevent the at the bottom of the pot shell from furnace heat radiation, and can make high temperature smoke tube plate inlet temperature drops, and supplemented by water ejector, no dead zone at the bottom of the drum, also can effectively prevent the tube plate because too cold, boiling and scaling and furnace bottom convex hull, smoke to the smoke chamber can dust removal effect, also reduces the original exhaust dust concentration.
5. Coal-fired boilers are compact in layout, small in floor space, convenient in transportation, fast in delivery, short in installation cycle, low in installation cost, low in user investment, and fast in recovery benefit.
6. Vertical coal burning boiler, hot water boiler and pipes with heating area are all straight pipes, and there are enough cleaning hand hole devices to facilitate manual mechanical cleaning of dirt and internal inspection. The horizontal coal fired atmospheric pressure hot water boiler is equipped with enough manhole in the upper part, personnel can enter the furnace body from the manhole, greatly facilitating the inspection and maintenance of the boiler.
