DZL coal fired steam boiler is a type of packaged boiler, which has the structure of three-pass, fire and water pipe combined. Both sides of the coal fired boiler are arranged with light pipe, water-cooling wall. Some ascending tubes are pulled towards the furnace, forming the heating surface of the furnace top. My plant coal fired boiler is used in many factories in Pakistan, stable and reliable operation, worthy of customer trust.
The adoption of new type, large block and chain grate realizes the mechanical combustion. The DZL series coal fired steam boiler is equipped with forced draft fan, induced draft fan, to operate the mechanical ventilation. Moreover, the slag remover is equipped, to realize the mechanical slagging.
The efficiency characteristics of DZL coal fired boilers are stable and have certain capacity of overload operation. The steam boiler automation level is high, the boiler feed water automatic regulation, high and low water level alarm, low water level interlock protection, lead, fan interlock protection. Boiler coal, slag and other operation mechanization, complete supporting auxiliary machines.
This series of steam boiler has compact structure, small floor space, short installation cycle, less installation cost and less capital investment. The flue gas temperature at the pipe plate is low, the pipe plate with single return trip is heated uniformly, and the low stress of the pipe plate makes the boiler safe and reliable in operation and long in service life. The heating surface layout of the coal-fired steam boiler is sufficient and reasonable. Boiler heating, pressure boost fast, full output, high thermal efficiency.
