Description

Energy-conservation retro-combustion civil heating boiler

Technical field

The utility model relates to a kind of civilian vertical heating boiler, especially relates to a kind of energy-conservation retro-combustion civil heating boiler.

Background technology

At present in most rural area, because living, people do not concentrate, civilian heating boiler is all used in the heating of most family, yet because it is little to be fit to home-use heating boiler volume, because the restriction of its furnace cavity, thereby general heat exchange efficiency is low, and flue dust is big, does not reach people's instructions for use.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of structure uniqueness, heat exchange efficiency height, energy-conservation retro-combustion civil heating boiler that flue dust is little are provided.

The utility model is realized in the following way:

A kind of energy-conservation retro-combustion civil heating boiler, comprise body of heater, burner hearth, fire grate, charcoal-adding opening, outlet flue, water inlet and delivery port, the body of heater bottom be provided with charcoal ash chamber, cigarette ash chamber successively, it is characterized in that: above-mentioned body of heater is that a round water jacket, its outside side are connected with semicircle outer water jacket, be provided with round water jacket in the burner hearth in body of heater, body of heater, outer water jacket and interior round water jacket are formed the flue of one " N " type in burner hearth;

Outside described semicircle, be connected with chimney on the outlet flue on water jacket top;

Top at described body of heater is combined with bell;

In described charcoal ash chamber, the cigarette ash chamber charcoal ash door and cigarette ash door are housed successively.

The utility model has following effect:

The utility model is by the round water jacket body of heater, round water jacket in the body of heater, the semicircle water jacket of the outer side of body of heater, thereby formed the flue of " N " type, fuel burns on fire grate like this, the flue that the hot flue gas that produces forms between three water jackets flows successively, not only prolonged flue gas flow, and in the process of hot flow of flue gas, short grained smoke dust that adheres on it and water jacket wall bump against, thereby make soot dust granule in time drop in the body of heater, it is low to enter the fume amount that chimney enters in the flue gas in the atmosphere like this, thereby not only flue gas flow is long, because the existence of three water jackets, make heat exchange area increase greatly, thus the heat exchange efficiency height, and environment protecting is good; Bell of the present utility model is provided with fire door, and fire door can be used for cooking, boiling water, and can realize multi-use.

The specific embodiment

A kind of energy-conservation retro-combustion civil heating boiler, comprise body of heater 1, burner hearth 2, fire grate 3, charcoal-adding opening 4, outlet flue 5, water inlet 8 and delivery port 9, body of heater 1 bottom be provided with charcoal ash chamber 6 successively, cigarette ash chamber 7, as shown in Figure 1: above-mentioned body of heater 1 is a round water jacket, its outside side is connected with semicircle outer water jacket 10, be provided with round water jacket 11 in the burner hearth 2 in body of heater 1, body of heater 1, outer water jacket 10 and interior round water jacket 11 are formed the flue 12 of one " N " type in burner hearth 2, outside semicircle, be connected with chimney 13 on the outlet flue 5 on water jacket 10 tops, be combined with bell 14 on the top of body of heater 1, charcoal ash chamber 6, charcoal ash door 15 and cigarette ash door 16 are housed in the cigarette ash chamber 7 successively.

As shown in Figure 1, fuel is added from charcoal-adding opening 4, fuel drops on the fire grate 3, the point stove, fuel is after burning on the fire grate 3, the hot flue gas that produces is along body of heater 1, outer water jacket 10 and interior round water jacket 11 are formed one " N " type in burner hearth 2 flue 12 flows, itself and three water jacket generation heat exchanges of flowing along with flue gas, thereby the water in the water jacket is heated, simultaneously because the heat space in the burner hearth 2, can boil water or cook on bell 14, charcoal ash that produces in its combustion process and cigarette ash door fall into charcoal ash chamber 6, cigarette ash chamber 7 gets final product from

charcoal ash door

15 and 16 taking-ups of cigarette ash door then.
