Abstract
The invention provides a coal saving and emission reduction method for a coal-fired boiler. The method is characterized by comprising the first step of screening fire coal, that is, commercial coal is screened into lump coal and powdered coal, the second step of conducting processing after fire coal screening, that is, the lump coal is soaked in an aqueous solution containing 5/10000 of potassium dihydrogen phosphate, 2/10000 of high-activity dried yeast, 10/10000 of washing powder, 10/10000 of salt and 10/10000 of quick lime for 1-30 minutes, or the aqueous solution accounting for 20%-30% of the quantity of the powdered coal is added into the powdered coal and then stirred evenly, and the third step of adding the fire coal into the boiler, that is, the lump coal is immediately added into a boiler furnace after being fished out of the aqueous solution, wherein the evenly-stirred wet powdered coal with the aqueous solution must be added into the boiler furnace in a wet state. Compared with the prior art, the coal saving and emission reduction method has the advantage that the fire coal can be saved by 30%-50%.
Description
Technical field
The present invention relates to a kind of coal-burning boiler, especially a kind of coal-burning boiler is saved the coal-fired method that reduces discharge.
Background technology
As everyone knows, the total amount of pollutant is directly proportional to coal-fired consumption, the heat that heating a certain amount of water needs to a certain temperature is a fixed number, the heat that coal-fired completing combustion can produce is also a fixed number, get on very well like this, should be by a certain amount of water to a certain temperature, also to ensure that the way that pollutant discharge amount is few only has one, that is exactly to improve coal-fired efficiency of combustion.Therefore, studying a kind of coal-burning boiler and save the coal-fired method that reduces discharge, is the current technical issues that need to address.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of coal-burning boiler and saves the coal-fired method that reduces discharge.
The technical scheme that the present invention solves its technical problem is:
Coal-burning boiler is saved a coal-fired method that reduces discharge, and its processing step comprises:
coal-fired screening-be filtered into lump coal and fine coal by marketable coal;
coal-fired screening post processing-soak 1～30 minute in the aqueous solution that contains 5/10000 potassium dihydrogen phosphate, 2/10000 high activity dried yeast, 10/10000 washing powder, 10/10000 salt, 10/10000 quick lime by lump coal; Or add the above-mentioned aqueous solution of coal amount 20 ﹪～30 ﹪ and stir in fine coal;
add immediately in burner hearth to adding after fire coal-lump coal is pulled out in the aqueous solution in boiler, add the above-mentioned aqueous solution and the wet-milling coal that stirs must add in burner hearth under hygrometric state.
Select scheme as one of the present invention, add fire coal in burner hearth before, open blower fan and air door, then add rapidly coal-fired, add after coal-fired 5～10 minutes and closed blower fan and air door, enter spontaneous combustion state, blower fan and air door are opened in spontaneous combustion again after 1～2 hour, add fire coal, so move in circles.
Compared with prior art, can save coal-fired 50 30 percent to percent by the inventive method.
Detailed description of the invention
Coal-burning boiler is saved a coal-fired method that reduces discharge, it is characterized in that, its processing step comprises:
coal-fired screening-be filtered into lump coal and fine coal by marketable coal;
coal-fired screening post processing-soak 1～30 minute in the aqueous solution that contains 5/10000 potassium dihydrogen phosphate, 2/10000 high activity dried yeast, 10/10000 washing powder, 10/10000 salt, 10/10000 quick lime by lump coal; Or add the above-mentioned aqueous solution of coal amount 20 ﹪～30 ﹪ and stir in fine coal;
add immediately in burner hearth to adding after fire coal-lump coal is pulled out in the aqueous solution in boiler, add the above-mentioned aqueous solution and the wet-milling coal that stirs must add in burner hearth under hygrometric state.
Add fire coal in burner hearth before, open blower fan and air door, then add rapidly fire coal, added after coal-fired 5～10 minutes and closed blower fan and air door, enter spontaneous combustion state, blower fan and air door are opened in spontaneous combustion again after 1～2 hour, add fire coal, so move in circles.
