Product application
Rated evaporation: 6-40t/h, rated working pressure: 1.25-3.82MPa
This series of products is a typical double-drum longitudinal "D" type quick-installed water tube boiler. The utility model is composed of an upper and lower drum, a membrane water wall, a superheater, a convection tube bundle and an economizer. The burner is arranged on the front wall, and after the fuel is burned in the furnace, the flue gas is discharged through the heat exchanger, the convection tube bundle and the economizer. The product has compact structure, small floor space and good flame fullness; it can expand upward by itself with the lower support mode; the membrane wall structure is adopted for the furnace water wall and the convection flue, the sealing property is good and the use of the refractory brick is effectively reduced. And the maintenance workload; the outer packaging is made of color steel plate, the appearance is beautiful and beautiful; the automatic burner is used, the combustion efficiency is high, and the ignition program control and overpressure and flameout protection functions are adopted; the quick installation structure can effectively shorten the installation period.
