Membrane water wall

Description

The water walls can be made of bare tubes or tubes which are welded together with steel bars (fins) to provide membrane wall panels which are insulated on one side and exposed to a furnace on the other.

The water wall is the main radiation heat surface, arranged inside the boiler chamber and precedes the heat exchange directly with the high temperature flame. The convection tubes are the convection heat surface of the boiler, arranged between the boiler chamber outlet and the end surface and proceed the heat exchange directly with the high temperature fume. The water wall and convection tubes are the main heat surface of the boiler, the tubes diameter for boiler generally used OD51-60mm boiler steel tubes or as the customers’ request.
