Abstract

The utility model belongs to heat supply technical field, which is mainly composed of a stove body, a water jacket pipe, a fire bar and a coal storage room. The lower middle part of the coal storage room is provided with an annular gas collecting room which is internally positioned with a gas collecting pipe with its another end communicated to the firebox. For the combustion system of the stove adopts the mode that the coals will first being gasified and then will enter the firebox for combustion and the coal gas generated will burn for second time after entering the firebox, therefore, the utility mode has complete combustion without carbon black generated and smoke emitted, but with good environmental protection performance and high heat efficiency.

Description

Normal pressure environmental protection combustion furnace

The utility model relates to a kind of normal pressure environmental protection combustion furnace that belongs to the heat supply process field.

The atmospheric pressure kiln that uses is mainly three types at present: oil burner, moulded coal stove and Loose-coal stove.Big environment protecting is good although oil burner is exerted oneself, and operating cost is higher, so the general user is beyond affordability; The moulded coal stove is because volume is bigger, and boiler output is little, and operating cost is also higher, so the general user also is reluctant to use; Loose-coal stove is owing to easy to use, coal wide material sources, and operating cost is low, so generally extensively adopted by the user.But the Loose-coal stove pollution problem is very serious, and China is perplexed by the coal combustion dust pollution problem always for many years, still fails better solutions so far certainly.

The purpose of this utility model is exactly to provide the normal pressure environmental protection combustion furnace of a kind of fuel for the coal that looses for solving disadvantages of background technology.

The purpose of this utility model is achieved in that it mainly is made up of body of heater, jacket pipe, fire grate, coal-storage room, be provided with annular gas-collecting chamber in the coal-storage room middle and lower part, be provided with discharge in the collection chamber, the other end of discharge passes to top, fire grate coal seam and is horizontal positioned, discharge horizontal positioned end is provided with steam vent, and fire grate tilts to place and can move horizontally.Annular gas-collecting chamber is made of arc and arc jacket pipe, and Open Side Down in annular gas-collecting chamber.

The utility model is compared background technology and had following advantage: 1. because this stove combustion system is to adopt coal to enter combustion chambers burn again after the gasification earlier, so there is not carbon black to produce, smokeless emission is so environmental-protecting performance is very good; 2. the dry distillation of coal of this stove, gasification, combustion integrative, rational in infrastructure, sufficient combustion, so exert oneself greatly, the thermal efficiency is up to 76%; 3. quick heating, stable, install simple, disposable throwing coal, easy and simple to handle; 4. can be used for warming oneself, heat up water, steam metal plate, bathing pool, use very extensive.

Fig. 1 is the utility model structure cutaway view.

Fig. 2 is that the utility model A is to side view.

Fig. 3 is the utility model A-A cutaway view.

The utility model is further described by embodiment below in conjunction with accompanying drawing: as Fig. 1, shown in Figure 3, the coal that looses is once filled through coal-storage room 5, behind the some combusting boiler, fire coal can form diffusing coal seam from top to bottom successively, slough the destructive distillation layer 3 of volatilization composition and sloughing the coke layer 4 of volatilize composition and carbon black, the coal gas of producing in the destructive distillation layer 3 is pooled in the annular gas-collecting chamber 2 that is made of arc 8 and arc jacket pipe 9 automatically, the steam vent 12 of coal gas on discharge 1 is discharged into the top of the coke layer 4 that is burning in the combustion chamber 6, and carries out second-time burning.Be provided with jacket pipe 10 at body of heater 7 middle parts, fire grate 11 can move horizontally, and boiler laterally spurs fire grate 11 and can make the ashes of sufficient combustion fall into grey-way after using a period of time.
