hot water boiler -- SZL4.2-0.7/95/70-AII

coal-firedboiler 1.Structure: water tube 2.Pressure:high Pressure 3.Style: Horizontal 4.Type: Chain layer combustion

 SZL7-1.0/115/70-AII

This type of boiler has two drums and water tube structure, making it easier to examine, repair and maintain. Natural circulating method makes sure that various loops possess certain flow speed, and no evaporation or water hammer happens when power or pump suddenly halts. Enough heat exchanging surface and proper furnace structure, excellent heat insulation and sealing quality lead to quite high thermal efficiency. Its dust eliminating concentration and blackness can satisfy the using demand. Natural circulation structure, lower inside water resistance and saving electricity are also the merits. The burning equipment is traveling grate, and the furnace arch covers large area of the grate, being suitable for variety of coal. 1.4MW to 4.2MW products adopt shop-assembled structure, and as for 7WM boilers, the two upper and lower parts are assembled on the working site, convenient for carrying and installing. It’s the ideal heating equipments for hospitals, schools, sealed army, industrial and mining enterprises, and so on. The type SZL7-1.0/115/70AII and SZL10.5-1.30/115/70AII are more proper for collecting and concentrating heat supply for residential districts.
