Summary of the invention

Technical problem to be solved by this invention provides and a kind ofly can effectively improve efficiency of combustion, has reduced soot emissions, prevents over-emitting black exhaust, reaches the gas making compound combustion vertical type furnace of clean combustion of coal purpose.

The present invention adopts following technical scheme: the present invention includes body of heater, burner hearth, be arranged on the convection current heat pipe face and the chimney of burner hearth upper end, be arranged on the water seal tank of burner hearth lower end, it is characterized in that described burner hearth includes coal gas and takes place and the coal-char combustion chamber, be arranged on the gas burner of coal gas generation and upper end, coal-char combustion chamber, be arranged on the coal gas orifice plate between coal gas generation and coal-char combustion chamber and the gas burner, be arranged on the igniting pond in the middle of the coal gas orifice plate and be arranged on connection coal gas on the coal gas orifice plate gas vent with coal-char combustion chamber and gas burner takes place, the perisporium in the gas burner, upper end of coal gas orifice plate evenly is provided with the tangential secondary air hole that is connected with air blast.

Take place to be provided with a wind air compartment that is connected with air blast at coal gas with the lower end of coal-char combustion chamber.

Upper end in the gas burner is provided with water sealed explosion door.

The igniting pond regulates airduct by the igniting pond and air blast is connected.

Good effect of the present invention is as follows: use the present invention, the coal gas that produces in coal gas generation and the coal-char combustion chamber enters the gas burner through the coal gas orifice plate, lighted by the lump coal flame that igniting Chi Zhongyi catches fire, mix the strong cyclone firing gas burner of formation with the tangential secondary wind that four tangential secondary air holes involve in, the semicoke that forms after the coal gasification burns away therein simultaneously, until forming lime-ash, add a dant incendivity 3~4 hours, need not to put a chimney on the stove and make the fire draw, since the coal gas orifice plate stop and the centrifugation of cyclone firing that flying dust is separated in a large number, has improved efficiency of combustion in stove, soot emissions have been reduced, prevent over-emitting black exhaust, reach the purpose of clean combustion of coal, use the present invention can burn the relatively poor smalls of ature of coal, cycle coal on demand also, stoker's labour intensity reduces.

Description of drawings

Accompanying drawing 1 is outside drawing of the present invention;

Accompanying drawing 2 is a structural representation of the present invention;

Accompanying drawing 3 is looked to analysing and observe for the A-A of accompanying drawing 1.

In the accompanying drawings: 1 water seal tank, 2 wind air compartments, 3 fire grates, 4 coal gas take place with coal-char combustion chamber, 5 coal gas orifice plates, 6 igniting ponds, 7 gas burners, 8 chimneys, 9 convection current heat pipe faces, 10 water sealed explosion doors, 11 secondary vane shape air channels, 12 secondary wind adjustment doors, 13 air blasts, 14 combustion chamber fire doors, 15 coal gas take place and airduct, 19 gas vents, 20 flame-observing holes, 21 coal seams are regulated in coal-char combustion chamber fire door, 16 tangential secondary air holes, 17 wind adjustment doors, 18 igniting ponds.

The specific embodiment

Below in conjunction with drawings and Examples the present invention is elaborated:

As accompanying drawing 1, shown in 2, the present invention includes body of heater, burner hearth, be arranged on the convection current heat pipe face 9 and the chimney 8 of burner hearth upper end, be arranged on the water seal tank 1 of burner hearth lower end, it is characterized in that described burner hearth includes coal gas and takes place and coal-char combustion chamber 4, be arranged on the gas burner 7 of coal gas generation and 4 upper ends, coal-char combustion chamber, be arranged on the coal gas orifice plate 5 between coal gas generation and coal-char combustion chamber 4 and the gas burner 7, be arranged on the igniting pond 6 in the middle of the coal gas orifice plate 5 and be arranged on connection coal gas on the coal gas orifice plate 5 gas vent 19 with coal-char combustion chamber 4 and gas burner 7 takes place, the perisporium in the gas burner, upper end 7 of coal gas orifice plate 5 evenly is provided with the tangential secondary air hole 16 that is connected with air blast 13.

The present invention takes place to be provided with a wind air compartment 2 that is connected with air blast 13 with the lower end of coal-char combustion chamber 4 at coal gas.

7 upper end is provided with water sealed explosion door 10 in the gas burner in the present invention.

The present invention lights a fire, and airduct 18 is regulated by the igniting pond in pond 6 and air blast 13 is connected.

Use the present invention, open combustion chamber fire door 14, at first in igniting pond 6, add an amount of kindling material and ut, open the igniting pond then and regulate airduct 18, close wind adjustment doors 17 simultaneously one time, secondary wind adjustment doors 12, open air blast 13, after the lump coal in the pond 6 of waiting to light a fire fire burns, opening coal gas takes place and coal-char combustion chamber fire door 15, on fire grate 3, add kindling material, and adding is generally the coal amount that operation in 3~4 hours needs, closing coal gas takes place and coal-char combustion chamber fire door 15 and combustion chamber fire door 14, open one time wind adjustment doors 17, turn down secondary wind adjustment doors 12 in right amount, a wind is admitted to wind air compartment 2 interior also risings and enters the coal seam through fire grate, treat coal gas take place with the coal-char combustion chamber in coal through oxidation, reduction, destructive distillation, dry, after the gasification, the coal gas that accumulates in top, coal seam through the gas vent 19 on the coal gas orifice plate 5 enter in the gas burner 7 with igniting pond 6 in the naked light fire burns that meeting, suitably open big secondary wind adjustment doors 12 according to the gas production size, air enters tangential secondary air hole 16 behind secondary vane shape air channel 11, as shown in Figure 3, because being tangent (or oblique), the inwall of tangential secondary air hole 16 and gas burner 7 is provided with, coal gas and mix and form strong swirl flame by the wind that is sprayed at a high speed by tangential secondary air hole 16, the while release heat, separate flue dust, the flue gas that produces enters atmosphere through chimney 8 behind gas burner 7 and convection current heat pipe face 9 absorption heats.Can observe combustion position in the stoves by being arranged on flame-observing hole 20 on the combustion chamber fire door 14 around here, under the burning normal condition, should be that the flame rotation is strong and degree of filling is good, and chimney is over-emitting black exhaust not.

The present invention utilizes producer gas and cyclone firing principle, fixed grate cycle coal and coal gas compound combustion have been realized, can improve efficiency of combustion, reduce soot emissions, prevent over-emitting black exhaust, reach the purpose of clean combustion of coal, use the present invention can burn the relatively poor smalls of ature of coal, because a coal combustion period reaches 3~4 hours, and need not to put a chimney on the stove and make the fire draw, and can effectively reduce stoker's labour intensity.Use boiler slag carbon content of the present invention can drop to below 12%, boiler thermal output can improve about 5 percentage points, flue dust initial ejection concentration and blackness of exhaustion stably reaching standard.
