Fire-tube type boiler

The fire-tube type boiler is 3PASS combustion gas flow , and the rear combustion chamber is made wet-type, so that the heat absorption is very high and the boiler is processed to the wave shape to cope with the thermal expansion, so that it is safe and easy to repair.
**Special Features**
? High thermal efficiency is maintained because it has no-scale inside the boiler.
? The rear combustion chamber has no loss of heat as a wet-type. The smoke tube is designed as corrugated-type to comply with thermal expansion, which features high heat absorption rate. High heat absorption rate per unit area approves it to be a very efficient boiler.
? The special design of inner tube does not allow tubes to be overheated by temperature variation.
? Temperature is precisely controlled by full automatic system and operating and handling is easy.
? It requires small installation area and has simple structure and nice appearance.
