Product description
  The newly designed 20-ton/hour saturated steam dual-gas boiler of our company adopts double drums and is vertically arranged. It can burn two different types of fuel, natural gas and biomass gas. The boiler adopts a D-shaped arrangement, with the combustion chamber on the right and the convection heating surface on the left. Because there is enough combustion space, it can ensure that the coke oven gas is fully burned. The steel tube economizer is arranged at the tail and assembled at the manufacturing plant. The maximum transport size is within the limits of railway transport size. The boiler water circulation adopts natural circulation.
  The boiler is small in size, small in area, short in installation cycle and low in installation cost.
  Safe gas system:
  The boiler is equipped with a burner on the front side of the furnace. Two explosion-proof doors are arranged at the rear wall of the boiler, and one explosion-proof door is arranged at the rear. Make the whole system more safe and reliable.
