With increasing demands for energy saving and environmental protection, people's awareness of energy saving and more intense. Tub boiler enterprise energy in boiler design has become one of the primary consideration. Ultimately bath boiler saving on energy saving two aspects: First, to improve work efficiency and combustion efficiency of the boiler; the other is the recovery of the resource reuse. Today to find out more baths boiler steam condensate and waste recycling. Improve condensate recovery, prevent the loss of bath boiler condensate is an important part of energy conservation. Improve not only the condensate recovery boiler water softening supplement reduced, relieves the load on the water treatment system, while improving the recovery so that the condensate water temperature increase. Each boiler feed water temperature increase 6 ℃, about 1 percent fuel savings, condensate emissions by installing steam traps to resolve. The condensate transportation problem has not been solved. Condensate recovery unless the user great terrain elevation, generally have to be set up in the boiler room in the basement, so that gravity condensate return, or in the middle of the boiler room and user settings pressurized condensate recovery pumps. Using the above method for recovering condensate recovery costs so greatly increased, which is not the ideal method. Foreign bath boiler has started using automatic condensate pump output recovered condensate. Such pumps do not need an external force, as long as the vapor line pass into a small amount of steam, can work continuously. Can make high condensate upgrade, but also make long-distance reinfusion condensate to the boiler room. Using this pump can certainly improve boiler thermal efficiency. Tub energy saving boiler to boiler change has become an inevitable trend in the development of future industrial boilers, as well as boiler enterprise development provides an opportunity and a challenge. Tub boiler companies want to further develop as soon as possible to grasp and waste steam condensate recovery technology right for your boiler fitted with energy-saving devices, to achieve long-term development.
