Unique Orientation
The choice of high quality boiler.Price:Unit: 15-150 U.S. dollar

The YLW series organic heat transfer boiler is a square box type assembled forced circulation chain grate boiler. The boiler is made up of the upper body (or upper body + lower body) , lower grate, and combined at site. The boiler’s radiant heating surface use a single furnace or a double furnace in snake-shape convection heat exchange tube. The tail is equipped with an air pre-heater, steam exhaust heat boiler, hot water economizer to recover exhaust heat according to the condition of user's exhaust heat usage, so that to reduce the temperature of discharged smoke, improve the heat efficiency, reduce fuel consumption, and save energy.
