Boiler Heater Parts Membrane Water Wall Panels For High Efficient Heat Exchange
Boiler Membrane Wall Introduction
Boiler water walls are membrane walls that are made of tubes welded together with or without a strip of metal in between. These walls form the enclosure of the coal combustion chamber. Water wall tubes are also referred to as the evaporator section; they contain water mostly in liquid form which gradually evaporates as it rises in the boiler.
Water wall is the main heating part of boiler,it consists of several rows of tubes,distributed around combustion chamber.Flue or steam is in the boiler to adopt heat from boiler furnace.
Mainly absorb the radiation heat from high temperature combustion products in furnace,the working medium move up and evaporate to steam.
Water wall panel for waste heat recovery boiler.We produce water wall panels.These are manufactured from carbon steel tubes according to customer drawings and specifications.Special attention should be paid to the ellipticity and thinning of the curved parts during manufacturing.
We are making and supplying all kinds of water wall panels.The tube we provide is known to bear large internal pressures as a continuous strip fin material wrapped around the tube coil.It is well known that these tubes provide heat evenly, increasing the heat output.
The main function of boiler water wall board is to absorb the heat generated by high temperature flame or flue and to produce steam or hot water in the pipe, thus reducing the temperature in the box.
A waterwall in a boiler is an furnace wall that is comprised of refractory and tubes in a water-tube boiler.The tubes are evenly spaced and generally connect to headers which in turn are connected back to the main generating bank of the boiler.They serve a two fold purpose here in that capture heat that would otherwise escape to the atmosphere and help heat the water in the boiler.And they also help keep the refractory cool(relatively speaking)This prevents spalling of the refractory.
1.ensure sealing of furnace wall and reduce air leakage in combustion chamber.
2.realize full water cooling of the combustion chamber, which is helpful to prevent coke formation in the case of intensified combustion.
3.small capacity of heat storage, fast heating of combustion chamber and rapid cooling, can shorten the cooling time of boiler start and stop.
4.it is appropriate to use pipe furnace wall, which greatly reduces the load of boiler frame and is convenient for suspension.
5.compared with the optical tube, the heat absorption capacity of the tube is improved.
6.the pre-combination degree of boiler components is improved, which is convenient and reduces the installation workload.
