Summary: | The utility model discloses a double side heating energy saving heating boiler, belonging to the technical field of the combustion equipment. On the reservation of the combustion chamber, the fire grate, the ash furnace, the coal charging hole, the ash drawing hole, the smoke outlet flue, and the water inner bag of the prior heating hot water boiler, a water inner bag cover added to the outside of the water inner bag keeps a clearance with the outer wall of the water inner bag, and an outer cover which keeps a clearance with the water inner bag cover is arranged outside the water inner bag cover. The water inner bag is heated, when the hot smoke flows across the clearance between the water inner bag cover and the water inner bag, with the positive effect of the utility model, and the water inner bag is heated again; meanwhile, the smoke having the waste heat flows across the clearance between the outer cover and the water inner bag cover, a good insulating layer is formed, and the fuel thermal efficiency can be improved by 25-30%. The other positive effect of the utility model is that the smoke is dispersed and cooled in the clearance between the water inner bag and the water inner bag cover and between the water inner bag cover and the outer cover, in favor of the sedimentation of the powder dust in the smoke, and most of the powder dust are deposited on the lower part of the boiler body; the dust content of the smoke is decreased, the discharge standard can be easily achieved, in favor of the environmental protection. |
