Membrane Water Wall of Boiler Water Cooling System

1. Membrane/Water Wall Material and Arrangement: The furnace and roof are made up of membrane water wall and hung on the steel structure by upper hanging suspender of water cooling upper header. Furnace intersecting surface is 3170×5290mm2 and the elevation of top furnace is 28877mm. The membrane water wall is made up of φ60×5 and 6×45 welding steel flat. The combustion chamber is made of φ60×4 steel tube and welded with pin to fasten refractory material. The upper part of combustion chamber connects with furnace membrane water wall. The lower part connects with water cooling wind chamber and water cooling air distributor. The water cooling wind chamber is made up of φ60 steel tube and welded with pins to fasten the refractory material. The water cooling distributor is welded with φ60 steel tube and 6X45 steel flat. The small holes on the steel flat connects with the funnel cap. The furnace divides left, right, front and back water circulation circuit. The s…
