boiler water wall tubes

Why the North to use more heating steam boiler water wall tubes? Why use more northern heating steam boiler? Actually, this is a very short answer, because the steam boiler is a large special equipment, in line with the northern region of central heating demand. Steam boiler to provide heat to warm the device process is simple: thin point heating device (burner) generates heat to heat transfer by radiation is absorbed by the water wall, the Wall Boiling water, a lot of steam into the drum for the occurrence of water separation (except for direct current furnace), separated into the full steam superheater, by radiation, convection method and continuous top horizontal flue furnace absorption, the flue gases heat the back pass, and the superheated steam reaches the desired operating temperature, then the heating temperature of the heating water, through the heating pipes in every household. Chengdu warm central heating because they do not belong, it is not necessary to use steam boiler as heat source.
