The invention relates to furnace heat engineering gas or liquid fuel fired and can be utilized for heating and hot-water supply of apartment buildings and production premises. A heating boiler comprises a housing (1) with a removable upper portion (2) on which an exhaust pipe (3) is mounted and a casing (4) with clearance and cover (5), a water jacket is arranged inside the housing with cold water supplying and hot water discharging branch pipes, said water jacket forms with the upper portion a gas collector, a firing chamber arranged in the bottom central portion with an arch lowering to its rear wall, a burning member arranged in a furnace chamber (10), a vertical gas flow passage embodied as a number of parallel rectangular ducts (14) evenly arranged over the water jacket volume, the arch at the rear wall of the furnace chamber embodied as stepped lowering. The technical result leads to enhancement of performance output operation efficiency of fuel combustion due to intensification of heat transfer directly in the furnace chamber. |
