Boiler Water Wall Panel

Cfb boiler membrane water wall panel boiler high thermal efficiency energy saving.

Boiler water wall panel. Furnace tube in biomass membrane water wall boiler asme or iso 3834 en standard. Hot water high pressure hot water and steam boilers fired with gas oil or biomass. Water wall panel boiler. Water wall panels are used in modern day boilers in place of steam generating tubes to reduce heat loss due to their gas tight nature and reduce insulation costs.

We fabricate water wall panels using automatic fin to tubes welding machines and large tube panel benders to achieve desired shape of panels which can have swaged ends stub welded to headers. Danstoker manufactures high capacity direct fired boilers with the radiation section built as a water tube or panel wall unit while the convection section is a fire tube unit. They contain water mostly in liquid form which gradually evaporates as it rises in the boiler. Boiler water wall panels are a series of tubes welded together tangentially or with membrane bar between them to form the walls of the boilers combustion chamber.

These boilers type combo may be fully assembled in our workshop or supplied in more sections to be assembled on site. Water wall tubes are also referred to as the evaporator section. Boiler water walls are membrane walls that are made of tubes welded together with or without a strip of metal in between. Inside is the flowing water or steam and the outside accepts the heat of the flame in the furnace of the boiler mainly absorbing the radiation heat of the high temperature combustion products in the furnace.

Typically two side walls a rear wall a front wall a floor and the roof section. These walls form the enclosure of the coal combustion chamber. Water wall panels are the main heating surface of boilers composed of numbers of rows of steel tubes arranged around the boiler corner.
