Abstract

The utility model provides a civil coal stove having a baking chamber, which is characterized in that the baking chamber for baking coal briquettes is arranged between an ash storing chamber and the lower part of a stove chamber. While in use, the coal briquettes to be added are baked and carbonized by means of the heat of the stove chamber. Decomposed harmful gas passes through the stove chamber for full burning. Thereby, smoke elimination and deodorization are effectively implemented. In addition, the utility model is suitable for making household coal stoves and has the advantages of fast firing and full burning.

Description

Civil coal stove having baking chamber

The utility model belongs to a kind of improved civil stove, and particularly a kind of civil stove that is provided with baking vessel is suitable for family and uses.

In prior art, all civil stoves all have only a vertical burner hearth, and for the coal furnace of upper coal feeding formula, the coal cinder of just having added can be emitted a large amount of harmful fuel gas under high temperature action, form smog, has both wasted heat energy, has polluted environment again.And the underfeed coal furnace, though can overcome above-mentioned shortcoming, owing to structure more complicated, inconvenient operation, cost height can not get applying.I had once designed a kind of civil stove with horizontal preheating chamber, and (number of patent application is: the CN912177000.4 applying date is: 910705), it is characterized in that a horizontal preheating chamber being set in upper furnace, make the coal cinder of interpolation just place on the burner hearth through after the preheating, reduce discharge of harmful gases, and have the advantage that igniting is fast, the thermal efficiency is high.Yet.Because this preheating chamber is communicated with the high-temperature region of burner hearth, the destructive distillation effect is not obvious, and this chamber is very near from fire door, coal cinder the flow through distance of combustion zone of the pernicious gas that volatilizes of being heated is shorter, just go to the outer contaminated environment of stove after still some pernicious gas also is not fully burned, produce smog and foul smell.

The purpose of this utility model is to overcome the deficiency of existing civil stove, and a kind of civil stove of equipment baking vessel of the deodorizing that can eliminate smoke more up hill and dale is provided.

Above-mentioned task is achieved in that this coal furnace mainly is made up of furnace shell, furnace panel, burner hearth, insulating, grate and Dust Storage Room, its improvements are that a baking vessel in order to the baking coal cinder that is formed by burner hearth extension downwards also is set below grate, this baking vessel is communicated with outward with stove by horizontal passage, be provided with seal closure in the outer end, between baking vessel and Dust Storage Room, also be provided with grate.

Fig. 1 is the cutaway view of a kind of concrete structure of the utility model.

Among the figure, (1) is furnace shell, and (2) are furnace panel, and (3) are burner hearth, and (4) are insulating, and (5) are grate, and (6) are baking vessel, and (7) are passage, and (8) are seal closure, and (9) are Dust Storage Room, and (10) are grate.

During use, the coal cinder that will add is put into baking vessel (6) earlier, because this place is the low-temperature space of coal furnace, can carry out sufficient destructive distillation to coal cinder, the volatile matter that the coal cinder decomposes is disengaged rises with a wind and can be fully burned through whole burner hearth, and sulfur dioxide, 3.4 benzos deleterious acidics such as (a) gas also are positioned at the upper strata through behind the high-temp combustion and the alkaline grieshoch absorption cleaning that forms, therefore deodorizing more up hill and dale can eliminate smoke, reduce environmental pollution, overcome the deficiency of prior art.Also have advantages such as the sufficient combustion that catches fire easily through the coal cinder after the destructive distillation, even be provided with after-combustion after the cooling, also igniting does not easily produce smog, and its effect is better than inflammable briquette.

When implementing the utility model, a horizontal preheating chamber (11) also can be set, make the coal cinder that will add obtain preheating on burner hearth (3) top, and combustion-supporting by this preheating chamber supply secondary hot-air, can obtain better eliminate smoke deodorizing and combustion efficiency.

The utility model is applicable to the fabricator coal furnace.

Claims

1, a kind of civil stove that is provided with baking vessel, mainly form by furnace shell, furnace panel, burner hearth, insulating, grate and Dust Storage Room, it is characterized in that also being provided with one by the downward baking vessel (6) that forms of extending of burner hearth (3) in grate (5) below, this baking vessel (6) is communicated with outward with stove by horizontal passage (7), be provided with seal closure (8) in the outer end, between baking vessel (6) and Dust Storage Room (9), also be provided with grate (10).
