Lord Fin Tube--The water wall, superheater, economizer, air preheater
Water cooling wall: is arranged in the furnace, and absorbs the heat of the furnace flame and the flue gas.
Superheater: absorption of flame in the furnace and the flue gas heat radiation superheater), or flue gas heat convection superheater). The saturated steam into superheated steam.
Economizer: backpass arranged in the low temperature part, the use of low-temperature flue gas heat, heating boiler feed water.
Air preheater: after the coal boiler is arranged in the province, the air is used to heat the air into the furnace or the milling system, so as to improve the efficiency of the boiler.
The heat transfer effect is not only related to the arrangement of the heating surface, but also the structure of the heating surface, the temperature and the flow rate of the gas, the temperature and the flow velocity of the working fluid, the cleaning of the heating surface.
