Abstract
The utility model relates to the combustion furnace that a kind of furnace bottom afterheat steam produces water-gas, lower portion of furnace body is provided with fire grate and ash pinch, and an ash pinch bottom is connected with water box, and water box communicates with the water inlet pipe outside stove, the upper end of water box is provided with and extends upwardly the steam pipe that ash discharge is scooped up, and steam pipe has a plurality of ventholes.This combustion furnace utilizes furnace bottom coal ash waste heat, water in water box is heated and produces water vapour upwards diffusion, produces water-gas with furnace high-temperature fuel reaction.Water-gas participates in burning together in stove, and the thermal efficiency improves greatly, and has reduced soot emissions, reaches the object of clean burning.
Description
Technical field
The utility model relates to the combustion furnace that a kind of furnace bottom afterheat steam produces water-gas, can in coal combustion process, produce water-gas simultaneously.
Background technology
At present, the combustion furnace of northern China rural area warming mainly be take coal as fuel, and peasant household chooses brown coal or the bituminous coal of low to medium price level mostly, ature of coal is poor, calorific value is on the low side, and while burning in common stove and accessory, fuel combustion utilization rate is very low, volume of smoke be can discharge, environmental pollution and energy waste caused.
Summary of the invention
The purpose of this utility model is to provide the combustion furnace that a kind of furnace bottom afterheat steam produces water-gas, this stove and accessory can produce water-gas in coal combustion process simultaneously, water-gas and coal burn jointly, increase burning of coal gross calorific value, improve efficiency of combustion, solve the shortcomings such as the existing combustion stove thermal efficiency is lower, flue dust is larger.
Furnace bottom afterheat steam produces a combustion furnace for water-gas, comprises body of heater, and lower portion of furnace body is provided with grate and ash pinch, described ash is scooped up bottom and is connected with water box, water box communicates with the water inlet pipe outside stove, and the upper end of water box is provided with and extends upwardly the steam pipe that ash discharge is scooped up, and steam pipe has a plurality of ventholes.
Described steam pipe top closure.
Described water inlet pipe is equipped with valve.
This combustion furnace utilizes furnace bottom coal ash waste heat, makes water in the water box generation water vapour that is heated, and water vapour spreads in burner hearth by the venthole of steam pipe, and reacts with high temperature coal and produce water-gas.CO in water-gas and CH
4deng many combustible gases, participate in together burning in burner hearth, not only the thermal efficiency improves greatly, and has reduced soot emissions, reaches the object of clean burning.This combustion furnace can simple refit form on common coal stove basis, and cost is low, to promoting the clean cooking stove development of China, has positive effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of this combustion furnace.
In figure, 1, body of heater, 2-valve, 3-water inlet pipe, 4-water box, 5-steam pipe, 6-venthole, 7-ash pinch, 8-fire grate.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 1, body of heater 1 bottom is provided with fire grate 8 and ash scoops up 7, and the top of grate 8 is burner hearths.Ash pinch 7 bottoms are connected with water box 4, and water box communicates with the water inlet pipe 3 outside stove, and water inlet pipe 3 is equipped with valve 2, and the upper end of water box 4 is provided with the steam pipe 5 stretching in burner hearth, and steam pipe 5 has a plurality of ventholes 6, and top closure.
Before water-gas gas processed, first Open valve 2, from water inlet pipe 3 to the interior topped up with water of water box 4, then valve-off 2.In hearth combustion process, the waste heat that the heat that fuel combustion produces and the scorching hot lime-ash dropping in ash scoops up 7 by fire grate 8 comprise, by ash, scooping up 7 heat conduction heats the water of water box 4, when heat is enough, water evaporation produces water vapour, and water vapour upwards passes through the upwards diffusion of venthole 6 on steam pipe 5 tops, and enters burner hearth by fire grate 8, react with scorching hot coal tar, produce water-gas.
