Abstract
The utility model relates to a pressureless hot-water boiler. The top of a boiler body is provided with a chimney, the middle part of the boiler body is a multi-back stroke flue, and the lower part of the boiler body is an inverse burning type combustion chamber whose lower side is a secondary combustion chamber. The bottom of the boiler body is provided with a boiler base, and the periphery of the boiler body is provided with a heating water jacket. The multi-back stroke flue is provided with a plurality of hollow heat absorbing plates in staggering way, and the plates are communicated with the heating water jacket. The water jackets of the top and the side wall of the inverse burning type combustion chamber and a hollow fire grate on the bottom are communicated with the heating water jacket of the boiler body The utility model has the advantages of complete combustion, high thermal efficiency, low fume exhaust quantity and simple structure.
Description
The utility model relates to a kind of unpressurized hot water boiler, and this boiler is used for hot water heating, thermal efficiency height, and smoke discharge amount is low.
Existing small-sized hot-water heating boiler often adopts Tunnel Furnace, because fire coal is added in the burner hearth, flue gas directly rises to chimney by burner hearth after the burning, and therefore volume of smoke that produces with burning and pernicious gas row cause atmosphere pollution to atmosphere.Chinese patent 91200443 discloses a kind of double-deck burning hot-water heating boiler, and this boiler has upper furnace body, lower furnace body, smoke barrier, heat-exchange tube and water leg, and this boiler combustion is more complete, and heat transfer efficiency is higher, but structure is complicated.
The purpose of this utility model is to propose a kind of unpressurized hot water boiler, and this boiler combustion is complete, thermal efficiency height, and smoke discharge amount is low, and simple in structure.
The purpose of this utility model is achieved in that a kind of unpressurized hot water boiler, body of heater, combustion chamber, heating water jacket are arranged, chimney is equipped with at its body of heater top, the body of heater middle part is many backhauls flue, the body of heater bottom is the counter-burning type combustion chamber, be secondary combustion chamber below this combustion chamber, the stove seat is equipped with in the bottom of body of heater, described heating water jacket is housed around the body of heater, the a plurality of hollow absorber plates of staggered installation in many backhauls flue, this plate is communicated with the heating water jacket, and the hollow fire grate of the water sleeve bottom of counter-burning type top of combustion chamber, sidewall is communicated with the heating water jacket of body of heater.The utility model is inserted diffusing coal cinder from counter-burning type combustion chamber fire door, fresh air enters counter-burning type combustion chamber and coal reactive combustion from fire door, its high-temperature flue gas enters secondary combustion chamber through the hollow fire grate of bottom, mix with the fresh air that enters this combustion chamber and to carry out second-time burning, enter many backhauls flue then, discharge boiler through chimney again along circuitous rising of flue.Because be full of recirculated water in the hollow fire grate, the heat major part of high-temperature flue gas is absorbed, the waste heat in many backhauls flue in its flue gas is absorbed a part by the hollow absorber plate in many backhauls flue once more, has significantly reduced scattering and disappearing of high-temperature flue gas heat.Can carry out second time burning at secondary combustion chamber without clean-burning imflammable gas and the residual coal of fritter that falls into secondary combustion chamber, the hollow absorber plate in many backhauls flue can play the effect of absorption, purification flue dust.
Compared with the prior art the utility model has burning fully, thermal efficiency height, and smoke discharge amount is low, advantage of simple structure.
The utility model is described in further detail below in conjunction with drawings and Examples.
