The steam heating furnace 1 is of an A, B, C three-chamber heating type, a furnace wall is arranged between two adjacent chambers, the three chambers share a convection section, and heat of the convection section is used for preheating main steam entering the device. The whole heating furnace adopts a forced ventilation mode, combustion air is heated to 90-120 ℃ after the heat of flue gas is recovered through a chimney, the temperature of flue gas exhaust is reduced, the heat efficiency of the steam heating furnace can reach 92-93%, and the heating furnace is more energy-saving compared with the heating furnace in the traditional process with 90% of heat efficiency.
