5MW Coal Hot Water Boiler

SZL series coal hot water boiler has the characteristics of high automation level, safe and efficient operation, convenient installation and so on. The design of the boiler is optimized and the problem of easy coking is solved. The thermal efficiency of the SZL types of boilers is significantly improved and the fuel cost is saved. The water wall on both sides of the furnace adopts membrane water wall structure; The water wall pipe of the front and back wall of the furnace extends downward to the upper part of the grate to form the front and back arch, which not only increases the sealing performance of the boiler, but also increases the volume of the furnace and the heating surface, and strengthens the strength of the back arch.
