Abstract

The utility model discloses a heating coal stove, which is composed of a stove body, a hearth in the stove body, a flue and a water sleeve communicated with an outlet pipe and a return pipe. A descending smoke pipe arranged in the water sleeve is arranged between the hearth and the flue, and lower end of the flue and bottom of the hearth are parallel. An upper opening of the descending smoke pipe is against to an upper opening of the hearth, and a lower opening of the descending smoke pipe is communicated with a lower opening of the flue. Upper and lower heat exchange water pipes are arranged horizontally in the flue. As adopting original descending flue, the coal stove makes the flammable materials in the smoke gas which is from the burning coal in the hearth fully decompose to burn, and release heat energy, thus being with high thermal efficiency, saving energy and being with small exhaust pollution.

Description

A kind of coal-fired stove for heating

Technical field

The utility model relates to domestic stove, promptly a kind of coal-fired stove for heating.

Background technology

The coal stove of using for heating is a lot, along with the raising of living standards of the people and the propelling of rural urbanization, more and more higher the northern area people to the demand of heating, but samll cities and towns and human body user can not advance and concentrate for dim due to limited conditions, and heating modes such as electricity is warm, air-conditioning are difficult to satisfy people's demand.Therefore be the main flow that the coal-fired stove for heating of the energy and the heating system that is commonly called as simple room heater become development with the coal.But the coal-fired stove for heating thermal efficiency of existing simple room heater is generally not high, and the pollution that flue dust causes is but very serious, causes the energy consumption height, the operating cost height, and the heating effect is not good enough.

The utility model content

The utility model is exactly the defective that exists at existing coal-fired stove for heating, and a kind of coal-fired stove for heating with innovation structure of design.This coal stove reaches the water jacket that communicates with outlet pipe, return pipe by the burner hearth in body of heater and the body of heater, flue and constitutes, the descending smoke pipe that places in the water jacket is arranged between burner hearth and the flue, the flue lower end is parallel with the burner hearth bottom height, descending smoke pipe is suitable for reading to be lower than that burner hearth is suitable for reading, end opening is communicated with the flue end opening, horizontal upward heat exchanging water pipe and following heat exchanging water pipe in the flue, descending smoke pipe is many of spacing parallel arrangings, is generally the 5-15 root.The moving grate that the band rocking bar is arranged under the fixed grate of burner hearth.The utility model adopts the structural design of descending smoke pipe, make the not most particle mass-energy of burner hearth internal combustion in descending smoke pipe, thoroughly dissolve burning, its heat energy can be fully and water jacket in recirculated water exchange, and up and down heat exchanging water pipe's further exchange in flue, make heat in fire coal and the flue gas can be fully, fully exchange with recirculated water.Therefore, the coal that the utility model coal-fired stove for heating adds can fully burn, and thoroughly turns to dust and ashes, and not only very clean from the flue dust of flue discharge suitable for reading, and temperature is very low, and heat-energy losses is very little, so the utility model coal stove is thermal efficiency height not only, and economize coal, pollute extremely low.According to test, only need 20 kilograms of bituminous coal every day with seven, eight groups of radiators of the utility model coal-fired stove for heating string band, the heating effect is splendid, is highly commended by customers deeply.This coal stove also is provided with moving grate and a plurality of cleaning door of band rocking bar, uses very convenient, the performance of banking up a fire.

Description of drawings

Fig. 1 adopts dim coal stove embodiment front elevational schematic for the utility model.

Fig. 2 is the embodiment schematic side view.

Fig. 3 is the embodiment schematic top plan view.

Among the figure, 1 lower deashing hole, 2 fixed grates, 3 moving grate rocking bars, 4 burner hearths, 5 preceding fire doors, 6 descending smoke pipes, 7 bodies of heater, 8 supernatant tepetates, 9 water jackets, heat exchanging water pipe on 10,11 exhaust openings, 12 smoke evacuation turnover panels, 13 delivery ports, 14 clear flue dust mouths, 15 flues, 16 shoot doors, 17 return pipes, 18 fire sealing covers, 19 converter mouth rings, 20 moving grates, 21 times heat exchanging water pipes.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, the utility model coal-fired stove for heating reaches the water jacket 9 that communicates with outlet pipe 13 and return pipe 17 by the burner hearth 4 in body of heater 7 and the body of heater 7, flue 15 and constitutes, the descending smoke pipe 6 that places in the water jacket 9 is arranged between its burner hearth 4 and the flue 15, flue 15 lower ends are parallel with burner hearth 4 bottom level, descending smoke pipe 6 is suitable for reading, and to be lower than burner hearth 4 suitable for reading, end opening is communicated with flue 15 end openings, horizontal upward heat exchanging water pipe 10 and following heat exchanging water pipe 21 in the flue 15.This coal-fired stove for heating is easy to use, and the outlet pipe 13 with coal-fired stove for heating before using is connected with the fin circulating water pipe with return pipe 17, raises that fire banking-up board 18 on the body of heater 7 can add anthracite or bituminous coal is lit a fire.Coal is in burner hearth 4 internal combustion, give recirculated water in the water jacket 9 with exchange heat, flue gas enters flue through descending smoke pipe 6 from flue 15 lower ends from burner hearth 4 tops, in lower smoke tube fully behind combustion decomposition and the heat-shift, pass following heat exchanging water pipe 21 and last heat exchanging water pipe 10 in the flue, heat is discharged from floss hole 11 at last by after recirculated water is given in exchange fully, flue turnover panel 12 can be controlled exhaust smoke level and the interior flame size of burner hearth and bank up a fire, but shakes moving grate 20 deashings, mediation burner hearth.Coal ash under the burner hearth can be removed through lower ash-valve 1, descending smoke pipe 6 and ash discharge can be dredged by side ash discharging hole 16 and last ash discharging hole 8.By side ash discharging hole 14,16 coal ash in the smokejack clearly.

Claims (2)

1, a kind of coal-fired stove for heating, reaching the water jacket (9) that communicates with outlet pipe (13) and return pipe (17) by the burner hearth (4) in body of heater (7) and the body of heater (7), flue (15) constitutes, it is characterized in that having between said burner hearth (4) and the flue (15) the descending smoke pipe (6) that places in the water jacket (9), flue (15) lower end is parallel with burner hearth (4) bottom level, end opening is communicated with flue (15) end opening, descending smoke pipe (6) is suitable for reading, and to be lower than burner hearth (4) suitable for reading, horizontally in the flue (15) goes up heat exchanging water pipe (10) and following heat exchanging water pipe (21).
