Abstract
The invention relates to a high-efficient combustion furnace with a steam-self-supplying combustion-supporting function, which comprises two main parts of a furnace body and a water tank, wherein the pitch between a grate and the water level in the water tank is 10-500mm, the burned-out coal slags or other solid substances fall into the water tank from the grate, a part of the water contacted with the slags can be immediately heated by the high-temperature slags to be boiled, the produced steam can rise into the combustion furnace, then enters a hearth by a very short travel, and then reacts with coal to produce coal gas, and the water has the combustion-supporting function. In addition, in the structure, the fly ash can be furthest reduced, so that a small combustion furnace can achieve the effect of clean operation with low cost.
Description
Technical field
The present invention relates to combustion furnace, especially for the efficient water burning-assist independent burning stove of coal hot-air system.
Background technology
Some split type hot-blast stove, combustion furnace separates with heat exchanger.For combustion furnace, comprise the low profile thermal wind furnace, the thermal efficiency is not high, mainly is chemically incomplete combustion and mechanical incomplete combustion, thereby discharges a large amount of CO and dense smoke; In addition, also there is the uncleanly problem of using in the combustion furnace of non-automatic fire grate, and coal ash scatters when operation and cleaning, and especially fireman's health is unfavorable to working environment.
The combustion furnace that many " combustion water is combustion-supporting " are arranged on the market, they be lean on the use stove can with heat energy produce steam, rather than for the disabled heat energy of combustion furnace.
Summary of the invention
The present invention is intended to solve above-mentioned two problems, proposes a kind of high efficiency combustion stove of confessing steam:
It comprises body of heater, two major parts in pond, wherein:
Body of heater comprises fire grate, at the rear portion exhaust smoke hole is set and the front portion is provided with fire door;
The fire grate position is higher than ground;
The front portion, pond is provided with the scarfing cinder water inlet, mainly is the slag of cleaning after-flame, because the external world can be through scarfing cinder water inlet and body of heater internal communication, so the partial combustion air also is provided simultaneously.
The spacing of fire grate and pond middle water level is 10mm to 500mm, less than the fall spacing of slag bath middle water level and fire grate of other boiler.The cinder of after-flame or its solid matter fall into the pond from fire grate; The part water that the slag of high temperature will contact with it is heated to the steam rising that boiling produces at once; Just get in the combustion furnace through very short stroke, with part coal in the burner hearth react generation coal gas, that is: C+H
2O → CO+H
2, just reduce water outlet, i.e. CO+O during burning
2→ CO
2, H
2+ O
2→ H
2O, water has wherein played the effect of auxiliary combustion.
The invention has the beneficial effects as follows:
1, water vapour is produced by the slag heating, but not other can make the heat energy of other purposes in the stove.
2, water is participated in reaction, the heat energy that the efficiency of combustion of raising consumes as the intermediate reaction thing much larger than water.
3, this structure has farthest reduced flying dust, makes small-sized combustion furnace reach the effect of low-cost cleaning operation.
4, the bottom provides preheating new wind.The scarfing cinder water inlet provides the partial combustion air simultaneously, and air gets into body of heater 1 inner also being preheating to about 100 ℃ before.

Fig. 1 is a front section view of the present invention, and Fig. 2 is a schematic perspective view of the present invention.
1: body of heater; 2: the pond; 3: fire grate; 4: exhaust smoke hole; 5: the scarfing cinder water inlet; 6: fire door.
The specific embodiment
As shown in the figure, the present invention mainly comprises body of heater 1 and pond 2, wherein:
Body of heater 1 comprises fire grate 3, exhaust smoke hole 4 and front portion are set at the rear portion is provided with fire door 6; 2 front portions, pond are provided with scarfing cinder water inlet 5; Fire grate 3 is than the high 50mm in ground.
Scarfing cinder water inlet 5 mainly is the slag of cleaning after-flame, because the external world can be through scarfing cinder water inlet 5 and body of heater 1 internal communication, so scarfing cinder water inlet 5 also provides the partial combustion air simultaneously, air also is preheating to about 100 ℃ before getting into body of heater 1 inside.Can also guarantee that operational efficiency is optimum through regulating the size control air inflow of scarfing cinder water inlet 5 in addition.
Add water in the operation forward direction pond 2, add to the fire grate spacing less than 50mm.
Slag falls into pond 2 during operation, and part water becomes in the steam entering body of heater 1 and partly carries out auxiliary combustion, is discharged from again.The slag and the water yield of evaporation that fall in the pond offset substantially.Can not produce flying dust.
Have a large amount of slags in the long-play pond 2 and account for 3/4ths of slag total amount, from pond 2, slag is drawn out, add enough water again.
Claims (2)
1. a high efficiency combustion stove of confessing steam added combustion comprises the body of heater 1 that is built into by refractory material, it is characterized in that:
There is fire door 6 body of heater 1 front portion, and there is exhaust smoke hole 4 at the rear portion, and pond 2 is arranged at the bottom;
Pond 2 forwardly is provided with scarfing cinder water inlet 5;
The spacing of fire grate 3 and pond 2 middle water levels is 10 to 500mm.
2. a kind of high efficiency combustion stove of confessing steam added combustion as claimed in claim 1 is characterized in that:
Fire grate 3 is than more than the high 5mm in ground.
