Abstract

The utility model discloses a high efficiency domestic coal stove causing no pollution. The domestic coal stove makes combustion exhaust gas lead to outside and has no air pollution of indoor rooms. Besides, the domestic coal stove has high heating efficiency. The domestic coal stove is technically characterized in that the upper part of a stove body is provided with a closure upper chamber to limit combustion exhaust gas from escaping towards indoor rooms. Besides, the combustion exhaust gas is leaded into outside through a gas induction pipe and an external pipe of the stove. The utility model has the advantages of no pollution, high thermal efficiency and large heating area compared with an opening domestic coal stove of the existing stove face. Besides, the stove fire of the high efficiency coal stove causing no pollution is free from the air flow of influence of surrounding.

Description

High efficiency coal stove causing no pollution

The utility model belongs to a kind of improved commercial coal stove, particularly can guide into burnt gas outdoor and makes indoor no air pollution and improve the commercial coal stove of the thermal efficiency.

The commercial coal stove of existing indoor use as honeycomb briquette stove, all is the combustion system that boiler face opens wide, though this is simple in structure, the waste gas that the burning of coal process comes out is then quite serious to the pollution of room air, and these waste gas contain SO ₂, CO, CO ₂, NO ₂, total hydrocarbon, aromatic hydrocarbons, heterocyclic compound and flue dust, caused the deterioration of living environment, and threatened the health of human body and shortened service life of indoor thing; On the other hand, because mode of heating is that so heating surface is little, stove fire is subject to the influence of air-flow on every side, causes the thermal efficiency low by the open type calcination of flame to the cooker bottom.

The purpose of this utility model provide a kind of can guide the burnt gas of indoor coal stove into outdoor, and make the heating surface area of cooker big, commercial coal stove that the thermal efficiency is high.

The utility model is achieved in that no air-polluting high efficiency civil coal stove comprises body of heater, toe board, fire grate, fire door, the inside of this body of heater has burner hearth, body of heater cavity of resorption, the stove extension tube attached that is characterised in that upper of furnace body has body of heater epicoele, epicoele capping, is positioned at the bleed Thiele tube of body of heater epicoele madial wall top, is communicated with the bleed Thiele tube of the present utility model.Wherein toe board is used to be positioned over above the burner hearth and to furnace chamber for cooker and is left enough air gaps, makes that burner hearth is unlikely to be shut by the cooker bottom; Fire grate is positioned at body of heater cavity of resorption top, burner hearth below, in order to the coal cinder of splendid attire in the supporting burner hearth, and can obtain enough air from the body of heater cavity of resorption when making the coal cinder burning; Fire door is as body of heater cavity of resorption and outside port, in order to the air inflow of control stove; Burner hearth is as the cavity of splendid attire coal cinder, the calory burning of coal cinder is risen and not to around diffusion; The epicoele capping is sealed the body of heater epicoele in order to after cooperating with the waist of cooker, makes upper of furnace body form an enclosed cavity, and the burning gases that produce from burner hearth just are limited in the enclosed cavity and do not distribute toward indoor like this; Be in the bleed Thiele tube in the enclosed cavity, with stove extension tube attached formation burnt gas is guided into outdoor path with its connection, it is to realize by the pore above the bleed Thiele tube that burnt gas enters the bleed Thiele tube, because the middle and lower part of cooker even can be that whole sidewall all is in the enclosed cavity, the hot gas of burning is subjected to the guiding of the bleed Thiele tube above the enclosed cavity and rises, middle and lower part or whole sidewall to cooker heat, the heating surface of cooker is big like this, airflow influence around stove fire is not subjected to, uniform heat distribution in the sealing epicoele is so improved the thermal efficiency of stove effectively.In order to adapt to the cooperation requirement of epicoele capping, the configurable difform various epicoele cappings of the utility model with difform cooker.When fire door is to regulate air inflow automatically according to fire box temperature, then can be in the scope of the best Control for Kiln Temperature, thus the thermal efficiency of stove being increased substantially contain charcoal with cinder obviously reduces.When the utility model is carried out structure of modification from burner hearth with the lower part, the technical solution of the utility model also is applicable to gaseous fuel, liquid fuel range, and plays same purpose.

Below in conjunction with accompanying drawing the utility model is done to describe more specifically.

Fig. 1 is the vertical profile schematic diagram of a kind of scheme of the utility model.

With reference to Fig. 1, no air-polluting high efficiency civil coal stove comprises body of heater 1, toe board 2, fire grate 3, fire door 4, body of heater 1 the inside comprises burner hearth 5, body of heater cavity of resorption 6, body of heater epicoele 7, epicoele capping 8 is matched with cooker 9 waists, body of heater epicoele 7 is realized sealing, there is a ring-type bleed Thiele tube 10 body of heater epicoele 7 madial walls top, bleed Thiele tube 10 madial walls tops is regular to be distributed with a plurality of pores 11, stove extension tube attached 12 is communicated with bleed Thiele tube 10, its outlet can directly be extended outdoor, also can insert charlie noble, fire door 4 can be regulated intake arbitrarily, in addition in order further to improve the completing combustion rate of coal, body of heater 1 sidewall the inside is provided with secondary wind inleting tube 13, in order to the air of body of heater cavity of resorption 6 directly is directed to burner hearth 5 tops.

During use, regulate fire door 4 air intakes, coal cinder burning in the burner hearth 5, to cooker 9 heating, the band hot gas that the burner hearth burning produces rises, and enters the body of heater epicoele 7 of sealing through toe board 2 air gaps, and risen by the guiding of pore 11, uphill process heats the cooker side, and burnt gas is discharged into outdoor through pore 11, bleed Thiele tube 10, stove extension tube attached 12 then.

Claims

1, no air-polluting high efficiency civil coal stove, comprise body of heater 1, toe board 2, fire grate 3, fire door 4, there are burner hearth 5, body of heater cavity of resorption 6 in body of heater 1 inside, the stove extension tube attached 12 that is characterised in that there are body of heater epicoele 7, epicoele capping 8 in body of heater 1 top, are positioned at the bleed Thiele tube 10 of body of heater epicoele 7 madial walls tops, are communicated with bleed Thiele tube 10 of the present utility model.

2,, it is characterized in that the regular pore 11 that is distributed with in madial wall top of this bleed Thiele tube 10 by the described commercial coal stove of claim 1.
