Generally, the water-wall pipe is laid around the boiler furnace wall, but we often place part of the water-wall pipes in the middle of the furnace in the large-capacity boilers.
The main functions of water-wall tube are as follows:
(1)Protect the furnace wall and reduce the erosion and damage of high temperature smoke and slag in the furnace to the furnace wall.
After installing water wall, the temperature of inner wall and flue gas temperature in furnace are greatly reduced, which can effectively prevent slag forming on furnace wall and heating surface, and reduce thickness and weight of furnace wall.
Modern large boiler, the use of furnace wall and water-cooled wall tube together to form a pipe-type or tube on the furnace wall, that is, the use of water-cooled wall tube suspended furnace wall.
(2)The high temperature flame in the furnace conducts heat to the water-wall tube, mainly by radiation.
The radiative heat transfer intensity is proportional to the fourth power of the absolute gas temperature.
Because the gas temperature in the furnace is very high, so, the water wall tube in the furnace to absorb radiation heat transfer is very strong, is the main boiler evaporation heating surface.
For high pressure and ultra-high pressure boilers, radiant superheater is usually arranged on the top of the furnace;
For the dc boiler, part of the preheating heating surface (equivalent to economizer) and overheating heating surface (equivalent to superheater) are often arranged in the water wall;
While the supercritical dc boiler, because there is no evaporation heating surface, the water wall is only used to heat water and superheated steam.
