Boiler Water Wall Panel

These boilers type combo may be fully assembled in our workshop or supplied in more sections to be assembled on site.

Boiler water wall panel.

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

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. These tubes contain mostly water in liquid form that slowly evaporates and rises in the boiler during combustion. 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. Water tube panel wall boilers.

These walls form the enclosure of the coal combustion chamber. Water wall tubes are also referred to as the evaporator section. Water wall panel boiler. Hot water high pressure hot water and steam boilers fired with gas oil or biomass.

Boiler water walls are membrane walls that are made of tubes welded together with or without a strip of metal in between. They contain water mostly in liquid form which gradually evaporates as it rises in the boiler. Furnace tube in biomass membrane water wall boiler asme or iso 3834 en standard.
