Abstract
This invention relates to a vertical back-fire coal-burning boiler, in which a body includes a gas generating chamber, a firebox and a burn-off chamber characterizing in applying a back-fire coal-burning mode and a vertical boiler, the upper part of which is set with a chimney and an ash-cleaning door, the lower part is set with a return pipe, the gas generating chamber includes a bunker, a feed mouth, an air inlet and a dregs cleaning port, the feed mouth and the air inlet are set with air duct, fire grates are set in the combustion chamber isolated by several water-jacket clapboards, and gas goes along two symmetrical dual-S, and multiple convection pipes are set in the burn-off chamber, which increases usage of fuel by two symmetrical dual-S paths of fuel and reduces temperature to 130deg.C from 300deg.C and applies natural air without blast or inducing so as to reduce cost greatly.
Description
Technical field
The present invention relates to a kind of coal-burning boiler, specifically a kind of vertical flashback type coal burning boiler.
Background technology
The small-sized multipurpose boiler that uses is generally direct-fired at present, the discharge flue that the burner hearth of the coal-burning boiler of direct combustion leads to the convection current heating section is generally in burner hearth above the fire grate, coal is on fire grate when work, to feed sufficient air in the burner hearth, allow coal that completing combustion under enough oxygen conditions is being arranged, air is to enter from fire grate below during coal burning, and coal is that discharge flue above the burner hearth enters the convection current heating section at the high-temperature flue gas after the burner hearth internal combustion.This direct-fired coal-burning boiler can produce a large amount of black smokes when burning, not only fuel availability is low, and contaminated environment.
Summary of the invention
For addressing the above problem, the invention provides and a kind ofly can play energy-conservation and reduce the vertical flashback type coal burning boiler of fume emission effect.
For achieving the above object, the present invention is by the following technical solutions:
A kind of vertical flashback type coal burning boiler, body of heater comprise gas generating chamber, combustion chamber and secondary furnace, it is characterized in that: adopt the coal-fired mode of backfire, boiler furnace is vertical, upper of furnace body is provided with chimney and shoot door, and chimney is positioned at the furnace roof upper middle position, and shoot door is positioned at chimney both sides, furnace roof top; The bottom is provided with return pipe; Gas generating chamber is provided with coal store, coal filling hole, air inlet and breast hole, and coal filling hole is in the positive centre position of gas generating chamber; Coal filling hole and air inlet are equipped with the air channel; Be provided with furnace grate tube in the combustion chamber, by several water jacket partitions the combustion chamber separated, the combustion gas path becomes two S type trends of two symmetries; Be provided with a plurality of convection tubes in the secondary furnace.
Usefulness compared with prior art of the present invention is:
Adopt the reverse combustion type coal combustion process, two S type trends that the combustion gas path becomes two symmetries have improved fuel availability, and the exhanst gas outlet temperature drops to 130 ℃ by 300 ℃; Adopt the nature air distribution,, greatly reduce use cost without equipment such as air blast, air inducing; By multiple spot air distribution and backfire, make fuel reach the purpose of completing combustion.
Description of drawings
Fig. 1 is the schematic diagram of vertical flashback type coal burning boiler.
Among the figure, 1 chimney, 2 shoot doors, 3 secondary furnaces, 4 combustion chambers, 5 coal filling holes, 6 air inlets, 7 convection tubes, 8 breast holes, 9 furnace grate tubes, 10 return pipes, 11 gas generating chamber, 12 coal stores, 13 water jacket partitions.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing and the specific embodiment:
A kind of vertical flashback type coal burning boiler, body of heater comprise gas generating chamber 11, combustion chamber 4 and secondary furnace 3, adopt the coal-fired mode of backfire, boiler furnace is vertical, upper of furnace body is provided with chimney 1 and two shoot doors 2, and chimney 1 is positioned at the furnace roof upper middle position, and shoot door 2 is positioned at chimney 1 both sides, furnace roof top; The bottom is provided with return pipe 10; Gas generating chamber 11 is provided with coal store 12, coal filling hole 5, two air inlets 6 and breast holes 8, and coal filling hole 5 is in the positive centre position of gas generating chamber 11; Coal filling hole 5 and two air inlets 6 are equipped with the air channel, wind at first enters the top of coal store 12 through the air channel, make and form backfire under the wind direction, wind is by breast hole 8 time, some wind enters in the stove from breast hole 8, form secondary air,, make fuel reach the purpose of completing combustion by multiple spot air distribution and backfire; Be provided with furnace grate tube 9 in the combustion chamber 4, combustion chamber 4 separated, improved combustion efficiency so greatly, make the combustion gas path become two S type trends of two symmetries by several water jacket partitions 13; Be provided with a plurality of convection tubes 7 in the secondary furnace 3, make full use of flue gas like this, increased the thermal efficiency.
