Description
[technical field] the utility model relates to a kind of coal clean combustion energy-saving, environmental protection boiler, belongs to the coal-burning boiler technical field.
[background technology] China is big coal country, and coal remains the main energy in considerable time, and yearly consumption occupies first place in the world.Coal also is resident's main domestic energy except generating.At present, the energy of boiler remains based on fire coal, produce many combustible hydrocarbon owing to coal burning is insufficient, contain many polycyclic aromatic hydrocarbons such as Polychlorinated biphenyls in the combustible hydrocarbon, they are main carcinogens, have a strong impact on the healthy of people, and a large amount of dischargings of combustible hydrocarbon cause environmental pollution.For this reason, people actively are devoted to the exploitation of environment-protection boiler.
As the patent No. is that 00229666.7 utility model patent specification discloses a kind of environment-protecting civil gas burner, and this gas burner makes the combustion chamber internal combustion of coal in encapsulation, coal is become coal gas supply with boiler by pipeline.Gas boiler needs to dispose a gas generator in use, because it is two independent parts, thereby not only can cause the waste of a large amount of human and material resources in use, and heat energy loss is big.
And for example the patent No. is that 01236608.0 utility model patent specification has been introduced a kind of environmental protection and energy saving gas boiler, gas burner and boiler-steam dome are designed to one, but because gas burner is made up of the gas generator, coal gas converter and gas burner's three parts that are installed in successively in the boiler-steam dome, not only occupied the boiler-steam dome useful space in large quantities, and boiler manufacturing process is also quite complicated.
The patent No. is the semi-coal gas clean combustion energy-saving environmental protection boiler that 03211746.9 utility model patent specification is introduced for another example, this patent comprise the fire grate that is installed in the body of heater and and gas generating chamber, gas generating chamber is arranged on body of heater dog-house place, and its inwall near burner hearth one side is provided with gas exit; Leave coal-fired passage between its inwall lower end and the fire grate, be provided with circulating water pipe and header thereof in the middle of the inwall.The steam transmitting pipe outlet of steam generator is arranged on the gas chamber inwall or is arranged on below the fire grate.Be provided with in the above-mentioned fire box and block wall with flues; This is provided with steam generator in the middle of blocking wall with flues, is connected with feed pipe and steam transmitting pipe on the steam generator; Block the wall with flues below and be provided with overheavy firing radiation chimney arch.Wall is provided with poly-warm chimney arch behind the body of heater waste heat Heat Room.Above-mentioned fire grate can adopt the scraper-type traveling-grate stoker.This boiler combustion heat exchange is made up of gas generating chamber, high temperature combustors and waste heat Heat Room three parts, fully utilize the characteristics separately of gas generator and plain cylindrical furnace, changed defectives such as simple coal gas generation line structure complexity, potential safety hazard is many and common coal-burning boiler smoke contamination is big, the thermal efficiency is low to a certain extent.But,, not only wasted the energy, and still environment polluted because coal burning is not very abundant; In addition, because that structural design unreasonable causes along the wind drift of boiler width direction is very big, stove internal combustion temperature is restricted, and can't improve the thermal efficiency of boiler to greatest extent.
[summary of the invention] the utility model has overcome the deficiency of above-mentioned prior art, its purpose is to provide a kind of coal clean combustion energy-saving, environmental protection boiler, this boiler not only energy-saving effect is obvious, and environmental benefit is also very remarkable, and is particularly better for about one ton boiler effect.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions.
A kind of coal clean combustion energy-saving, environmental protection boiler, comprise the fire grate that is installed in the body of heater and and gas generating chamber, gas generating chamber is arranged on an end of body of heater, and its inwall near burner hearth one side is provided with gas exit, and the coal gas that gas generating chamber is produced enters fire box by this outlet; Leave coal-fired passage between this inwall lower end and the fire grate, make the fire coal on gas generating chamber's fire grate, under fire grate drives, enter fire box by coal-fired passage; Be provided with water layer mid-board and main combustion chamber water layer partition wall in the fire box, it is characterized in that said main combustion chamber water layer partition wall is provided with the secondary blowing system, its plane is vertical with airflow direction.Being provided with of secondary blowing system can reduce greatly along the wind drift of boiler width direction, reduces the primary air flow of boiler, improves stove internal combustion temperature, and then improves boiler thermal output.
Above-mentioned boiler body shell 1 side end face is provided with the coal bunker 5 and coal seam adjustable plate 6, coal seam adjusting handle 7 that is used for splendid attire coal.
Water layer mid-board in the above-mentioned fire box and main combustion chamber water layer partition wall get up preheating zone and primary zone at interval, form two combustion chambers and a waste heat Heat Room.The inwall of above-mentioned gas generating chamber can be built or prefabricated forming with refractory material.In order to make full use of the heat that gas generating chamber produces, improve boiler thermal output, can in the middle of gas generating chamber's inwall, be provided with circulating water pipe and header thereof.
For coal-fired combustible can fully be burnt, to treat to start fire grate after the boiler normal combustion, the fire coal with not having burning in the gas generating chamber or burning is transported to the burner hearth high-temperature region and burns away.In order to prevent that fire coal from " skidding " on fire grate, above-mentioned fire grate can adopt the scraper-type traveling-grate stoker, and the monolithic fire grate structure is inverted "L" shaped, drives fire coal by the scraper plate fire grate and together moves with fire grate, enters fire box.
Coal clean combustion energy-saving, environmental protection boiler provided by the utility model, combustion heat-exchange is made up of gas generating chamber, high temperature combustors and waste heat Heat Room three parts, coal burning is abundant, both improved the combustion utilization efficiency of coal, save the energy, overcome the big defective of common coal-burning boiler smoke contamination again.And, because the setting of secondary blowing system has reduced greatly along the wind drift of boiler width direction, reduced the primary air flow of boiler, improved stove internal combustion temperature, energy-saving effect is particularly evident, environmental benefit is also very remarkable, is specially adapted to the boiler about a ton.
