The stove comprises a stove body, and grates, a furnace and a bottom which are arranged in the stove body, wherein a material adding hole and a smoke vent are arranged on the stove body. The stove is characterized in that the furnace is divided into an upper space and a lower space; the lower space is used as a gasification chamber; the upper closed space is used as a burning chamber; a fire guide cylinder provided with air holes is arranged in the gasification chamber; the bottom of the fire guide cylinder is communicated with the grates and the bottom of the furnace; and the upper hole of the fire guide cylinder is communicated with the burning chamber. The stove can be used for burning coal and firewood, has the advantages of no environment pollution, high heat efficiency and simple structure, and suits generalization in rural areas.

Description

A kind of civilian coal, bavin gasification direct-combustion stove

Technical field

The utility model relates to stove and accessory, relates in particular to domestic stove.

Background technology

Traditional Civil energy-saving cooking stove, no matter cook water boiler, warming stove, the heating dual-purpose stove of still cooking all is to be provided with fire grate in body of heater, and the top of fire grate is a burner hearth, and the below of fire grate is a furnace bottom, and body of heater is provided with and extraneous charge door and the smokejack that communicates.Flue gas was big when the weak point of this traditional stove and accessory was the burning of coal bavin, the chimney over-emitting black exhaust, and contaminated environment, it is insufficient to burn, because the insufficient flare of burning is not prosperous, influence is heated up water and is cooked.

At present, also have a kind of gasification combustion furnace on the market, its structure is that a gasification installation is arranged, and the fuel gas that bavin, grass produce leads to indirect burning on the burner by pipe, so complex structure.

Summary of the invention

The utility model provides a kind of coal simple in structure, the dual-purpose gasification direct-combustion stove of bavin for solving existing domestic stove over-emitting black exhaust, the not prosperous and existing gasification furnace structure challenge of flare.

Structure of the present utility model is, comprise body of heater, be provided with fire grate, burner hearth and furnace bottom in the body of heater, body of heater is provided with charge door and smokejack, it is characterized in that, burner hearth is partitioned into upper and lower two spaces, and lower space is a vaporizer, and the space that top is worn-out mouthful is the combustion chamber, portfire is set in the vaporizer, be furnished with passage on the portfire, the end mouth of portfire is conducted by fire grate and furnace bottom, and the suitable for reading and combustion chamber of portfire communicates.

Its theory of combustion is, ignite after dosing coal, bavin in the vaporizer, the back generation under anoxic flames of anger condition of sealing up a door is gasified, fuel gas is under the negative pressure of chimney, through hole by portfire enters the combustion chamber and lights the back and produce flare, carries out smokeless combustion fully by the comburant oxygen that enters from furnace bottom.

Good effect of the present utility model is: 1, coal, the dual-purpose use of bavin are flexible; 2, over-emitting black exhaust not, the sooting the bottom of a pan is not free from environmental pollution; 3, flare is prosperous, the calorific value height, and cooking, it is fast to heat up water; 4, simple in structure, be suitable for promoting in vast rural area.

The specific embodiment

Further specify with reference to the structure of accompanying drawing the application.

Shown in Figure 1 the is structure of furnace body of stove of cooking of heating up water, as shown in the figure, it is to be provided with fire grate 3 in body of heater 1, furnace bottom 4 and burner hearth, fire grate below 3 for furnace bottom 4 be used to remove lime-ash and air inlet combustion-supporting, the burner hearth of fire grate 3 tops is a vaporizer 8, vaporizer 8 tops are for placing pot, the combustion chamber 9 of heating cookers such as kettle, portfire 6 is set in the vaporizer 8, be furnished with passage 7 on the portfire 6, the end mouth of portfire 6 is conducted by fire grate 3 and furnace bottom 4, and the suitable for reading and combustion chamber 9 of portfire 6 communicates, vaporizer 8 is provided with and the extraneous charge door 2 that communicates, charge door 2 is provided with seals up a door, and a side of combustion chamber 9 is provided with smokejack 10, and smokejack 10 connects chimney.

In order to regulate the air inflow of furnace bottom, in the import of furnace bottom 4, also air door 5 can be set.

The cook structure of furnace body of dual-purpose stove of shown in Figure 2 is warming stove or heating, different with Fig. 1 is, the combustion chamber 9 on body of heater 1 top need be processed between as shown in Figure 2 double walled hot water 11.
