Description
Technical field
The present invention relates to a kind of boiler, particularly a kind of is the boiler of fuel with living beings.
Background technology
At present, the domestic boiler that has 60～700,000 in operation approximately is from fuel structure, because the total energy feature of China is " rich coal, few oil, gas is arranged ", in medium small boiler, coal-burning boiler accounts for 80%, the oil gas boiler accounts for more than 15%, and boilers heated electrically only accounts for more than 1%.Coal-burning boiler year, coal consumption reached 400,000,000 tons, and particularly northern area directly is that the boiler of fuel accounts for more than 80% with the raw coal.Show according to the national statistics data, China's Air Pollutant Emission amount 70% from coal burning, wherein 60% is the flue dust of discharged from coal-fired boiler.Sulfur dioxide (the SO of discharged from coal-fired boiler
2) account for China sulfur dioxide (SO
2) more than 90% of total release, nitrogen oxide (NO
X) discharging accounts for more than 65% of total release, the annual because direct economic loss that atmosphere pollution causes is up to 20,000,000,000 yuans.This shows that the discharge capacity of controlling fire coal boiler fume effectively is to improve direct, the most effective means of environment.In addition, because the coal markup is excessive, the operating cost of coal-burning boiler sharply strengthens, and is current, and the operating cost that reduces boiler also is the task of top priority.
China is a large agricultural country, and the living beings kind is a lot, enormous amount, more common have yule logs, beanstalk, straw, stalk, corncob, rice husk, sawdust, a bagasse etc., according to statistics, but China's agricultural crop straw collecting amount is about 4.5 hundred million tons every year, amounts to 1.8 hundred million tons of standard coals; 5,000 ten thousand tons on rice husk is amounted to 2,000 ten thousand tons of standard coals; About 2400 ten thousand steres of the wooden discarded object that produces in the forestry process are amounted to 1,500,000 tons of standard coals; The amount of providing rationally of various natural yule logs is 1.4 hundred million tons, amounts to 0.74 hundred million tons of standard coals.But compare with the consumption figure of fossil fuel in China primary energy, the biomass energy portion is also little, and it is about 16% that biomass energy accounts for primary energy proportion in 2005, and in commerce with in can structure, but less than 1%.Jilin Province is big agricultural province, every year is when producing shiploads of merchandise grain, the living beings such as maize straw of subsidiary output can be described as has no way of consuming, pile up all over the mountains and plains, small part is as common fuel or livestock forage, major part then is wasted or burns in the open air, and environment is caused very big influence, and is a kind of great waste.
Summary of the invention
The purpose of this invention is to provide a kind of is the boiler of fuel with living beings, this kind boiler can biomass burning, also can burning coal, and should be that the boiler of fuel can utilize fully to living beings with living beings, this boiler is burning coal not, has reduced flue dust, sulfur dioxide (SO
2), nitrogen oxide (NO
X) discharging, simultaneously, reduced the operating cost of boiler.
The present invention is made up of boiler body and conveying device, boiler body wherein is common coal-burning boiler, conveying device is arranged on the front portion of boiler body, the conveyer belt height of conveying device equals or a little more than the fire grate of boiler body, the front portion of boiler body offers charging aperture, this charging aperture is provided with outside striker plate and inner shelves coal plate, the anterior charging aperture place of boiler body is horizontally arranged with a passive feed roller, the position of this passive feed roller is higher than fire grate, the height of this passive feed roller can be regulated automatically with the thickness of material, dock with fire grate the bottom that the front end of conveying device is positioned at passive feed roller, conveying device is identical with the linear velocity that fire grate rotates, conveying device is a packaged type, conveying device and boiler body are connected and fixed with connecting rod, during use, dock with the passive feed roller and the fire grate of boiler body front portion at the charging aperture place that moves to the boiler body front portion; When not using, shift out conveying device, the striker plate at boiler body charging aperture place is closed get final product, this moment, boiler body can only be fuel with coal.
Operation principle of the present invention is: directly by the combustion chamber internal combustion of conveyer belt apparatus automatic transport to boiler body, boiler can only be fuel with living beings to biomass fuel without pulverizing, and plant ash that its burning back produces can be used as the fertilizer of crops use; This boiler can be the fuel of boiler with coal also.
The invention has the beneficial effects as follows:
1, this kind boiler can biomass burning, also can burning coal, can utilize fully living beings during with living beings for fuel, and this boiler has reduced flue dust, sulfur dioxide (SO
2), nitrogen oxide (NO
X) discharging, help environmental protection, simultaneously, reduced the operating cost of boiler.
2, boiler is fuel with living beings, and the peasant is increased income, and helps peasant's extra earning.
