Water Tube Steam Boiler
FANGKUAI’s water tube steam boiler is a steam boiler with a double-drum longitudinal arrangement, full-membrane water-cooled wall, D-shaped furnace natural circulation, and micro-positive pressure combustion. Seam steel tubes form convection tube bundles, and the right side is the combustion chamber composed of upper and lower headers and membrane walls. The burner is fixed on the front wall. After the fuel is sprayed out by the burner, it burns in the furnace (the first return pass) with slight positive pressure. After the high-temperature flue gas radiates and releases heat, it turns 180° to the left behind the furnace and enters the second pass. The convection tube bank of the second pass flows to the front of the furnace, turns 180° to the right in front of the furnace, enters the convection tube bank of the economizer (the third return pass), then passes through the condenser to fully exchange heat, and finally enters the chimney through the flue and discharges into the atmosphere.
