Abstract

The utility model relates to a civil coal gasifying furnace which is provided with a furnace body (10), a furnace chamber (11), a furnace surface (6) and a slag outlet (13). The utility model is characterized in that the upper end port of the furnace chamber of the civil coal gasifying furnace is also provided with a steam generating sleeve (4), and the upper end of the steam generating sleeve is provided with a fire collecting furnace sleeve (5); a steam pipeline is led out from the steam generating sleeve, and a regulating valve (2) is arranged on the pipeline; the lower end of the steam pipeline is led to an air inlet of the furnace chamber to be sheathed with the air inlet of the furnace chamber; the other side of the steam generating sleeve is provided with a water receiver (7) which enters the steam generating sleeve through the pipeline through a pipeline, and a one-way flow-limiting valve (8) is arranged on the pipeline; the lower part of the furnace chamber is provided with a grate (12). The utility model has the advantages that the furnace structure is simple; the operation is convenient; the heating value and the heat efficiency of the coal are raised; the heat resource is thoroughly used, and the waste is reduced.

Description

Civilian coal gasification furnace

Technical field:

The utility model belongs to the domestic stove technical field, and a kind of coal gasification reaction principle of utilizing is under the coal burning condition, add gasifying medium, make its reaction generate fuel gas,, thereby reach the civilian coal gasification furnace that firepower is more violent, calorific value is higher directly in the stove internal combustion.

Background technology:

At present, a kind of burning moulded coal of the common coal furnace of family expenses, the another kind of coal that burns, the stove and accessory that burns coal is a combustibility of utilizing coal, place and space that the incendivity of forming by its shaft, burner hearth, boiler face produces heat, the heat of generation is again in order to cook, to warm oneself and other purposes; Such Range structure is simple, processing ease, but its thermal efficiency is lower.In the regular job process, also need frequently to change coal, and might not represent when changing coal burn coal and do not had caloric value, just caloric value has reduced, and is not enough to the instructions for use of supporting user, and the caloric value of losing in this process is exactly a kind of very big wasting of resources.Such as: be used for as cook, when heating up water because its thermal efficiency is not high, its required operation is just long running time, wastes time and energy the waste resource.

Summary of the invention:

In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of civilian coal gasification furnace, and its Range structure is simple, and processing ease improves the caloric value and the thermal effect of coal greatly, makes full use of thermal resource, cuts the waste.

The utility model adopts following technical scheme to finish the foregoing invention purpose:

Described civilian coal gasification furnace, have body of heater, burner hearth, boiler face, slag notch, it also is provided with the steam generation cover in the burner hearth upper port, there is poly-stove cover the upper end of steam generation cover, draws a steam pipework from the steam generation cover, and control valve is set on the pipeline, the lower end of steam pipework is passed into the air inlet place of burner hearth, with the air inlet of burner hearth suit mutually; The opposite side device water receiver of steam generation cover enters in the steam generation cover by pipeline, and pipeline is provided with single-way flow restricting valve; The bottom of burner hearth is provided with the arch fire grate.

The utility model is owing to adopt technical scheme as mentioned above, and it has following good effect:

Because it is on common coal stove architecture basics, install the steam generation cover additional, utilize air and suitable quantity of water steam mixture as gasifying agent with at the coal reaction of burner hearth internal combustion, gasifying agent is converted into imflammable gas with the carbon in the coal, fuel gas is directly in the stove internal combustion, increase combustion heat value widely, utilized the thermal efficiency of coal fully.Can quicken and improve heat energy utilization, time saving and energy saving, reduce the wasting of resources.

The bottom of coal-fired furnace cavity is provided with arch fire grate structure, and the coal that enters in the burner hearth is fully burnt.

The drawing explanation:

Fig. 1 is civilian coal gasification furnace structural representation:

Shown in the figure: 1-blast pipe, 2-control valve, 3-steam outleting pipe, 4-steam generation cover, 5-fire collecting cover, 6-boiler face, 7-water receiver, 8-check valve, 9-water inlet pipe, 10-body of heater, 11-burner hearth, 12-arch fire grate, 13-slag notch.

The specific embodiment:

As shown in fig. 1: this civilian coal gasification furnace, have body of heater (10), burner hearth (11), boiler face (6), slag notch (13), it also is provided with steam generation cover (4) in the burner hearth upper port, there is poly-stove cover (5) upper end of steam generation cover, draws a steam pipework (3) from the steam generation cover, and control valve (2) is set on the pipeline, the lower end of steam pipework is passed into the air inlet place of burner hearth, with the air inlet of burner hearth suit mutually; The opposite side device water receiver (7) of steam generation cover enters in the steam generation cover by pipeline, and pipeline is provided with single-way flow restricting valve (8); The bottom of burner hearth is provided with arch fire grate (12).Add entry in water receiver, water flows into the steam generation cover along water inlet pipe by check valve.When treating that temperature in the burner hearth acquires a certain degree, heat is delivered in the steam generation cover, make a part of water wherein become water vapour, open control valve, the water vapour that produce in the steam generation cover this moment mixes with air in the blast pipe along steam outleting pipe, enter the bottom of burner hearth and react with the coal that burns therein, the fuel gas of generation is directly lighted.By steam generation cover, receipts fire cover, boiler face, flame directly acts on user's utensil.When not needing to use, blast pipe is sealed, closed control valve and get final product.Behind coal burning-out in the stove, residue falls along the arch fire grate, and the slag notch of body of heater bottom is opened, and directly slagging tap gets final product.

Claims

1, a kind of civilian coal gasification furnace, have body of heater (10), burner hearth (11), boiler face (6), slag notch (13), it is characterized in that: described civilian coal gasification furnace, it also is provided with steam generation cover (4) in the burner hearth upper port, and there is poly-stove cover (5) upper end of steam generation cover, from the steam generation cover, draw a steam pipework, control valve (2) is set on the pipeline, and the lower end of steam pipework is passed into the air inlet place of burner hearth, with the air inlet of burner hearth suit mutually; The opposite side device water receiver (7) of steam generation cover enters in the steam generation cover by pipeline, and pipeline is provided with single-way flow restricting valve (8); The bottom of burner hearth is provided with arch fire grate (12).
