Introduction
This series steam boiler is suitable for small and medium enterprises, institutions, schools, guesthouse, hotel, bath center and residential areas, providing heating and hot water.

Advantages
1. Using our unique BMF combustion technology, full fuel combustion, high utilization;
2. “8”character flue arrangement make the smoke gas smoothly enter into front smoke chamber through the flue, which effectively reduce the smoke temperature of tube plate in the high temperature zone and prevent the tube sheet cracks and pipe explosion accidents; a single backhaul thread fireworks tube in the boiler barrel result in good heat transfer effect.
3. Optimized design flue gas velocity, smoke within smoke pipe has the function of self-cleaning , avoiding fouling in the smoke tube and wear of smoke tube;
4. Using shunt ejector cycle technology, unblocked circulation, reliable operation;
5. Design special furnace arch. according to the characteristics of biomass fuel. Front and rear arch maches with each other. The unique secondary oxygen device to increase the rate of fuel burn out and solve the problem of black smoke combustion of biomass fuels;
6. Dust of the chamber outlet separates inertially, which effectively reduce exhaust gas dust concentration, and reduce wear and tear on the rear of the heating surface;
7. Furnace using thicker quality insulation materials keep warm, low heat loss;
8. Quick installation, easy installation;
9. Special furnace heating surface layout, no coke, better adaptability.
