Fire tube steam boiler


   The fire tube boiler is the flue gas generated after fuel combustion flowing through the fire tube or flue pipe, heating the water, steam or steam-water mixture outside the fire tube or flue pipe.9zRIndustrial Steam Boiler

  Therefore, the capacity and pressure of fire tube boilers are greatly limited. Generally, the evaporation rate does not exceed 10 t/h and the pressure does not exceed 2 MPa. Due to the limitation of the drum, the heating area of the boiler is smaller, so the exhaust gas temperature is higher and the efficiency of the boiler is lower. The metal utilization rate of fire tube boilers is as high as 10t/t steam. According to the above characteristics of fire tube boilers, fire tube boilers are widely used in small and medium-sized factories, heating, locomotives, ships and other mobile devices.9zRIndustrial Steam Boiler
