Abstract
The invention relates to an additive for improving the coal combustion efficiency, which relates to an additive for improving the combustion performance of fired coal. The invention aims to provide the fired coal additive capable of improving the combustion efficiency of faulty coal and the fired coal with low thermal efficiency. The invention provides the fired coal additive which not only is favorable for full combustion of the raw coal and saves the raw coal but also can absorb harmful gas generated in the combustion process of the raw coal, so as to be favorable for environmental protection, aiming at the conditions that the prior lagged combustion technology wastes a large quantity of raw coal and simultaneously severely pollutes the air. The formula of the additive comprises the following compositions in portion by weight: 5 to 30 portions of calcium oxide, 2 to 10 portions of sodium hydroxide, 3 to 10 portions of potassium permanganate, 3 to 15 portions of manganese dioxide, 1 to 5 portions of magnesium oxide, 3 to 10 portions of sodium nitrate, 1 to 5 portions of potassium chloride, 1 to 5 portions of barium nitrate and 3 to 15 portions of quicklime.
Description
Technical field:
The present invention relates to a kind of additive that improves combustionproperty at fire coal.
Background field:
China is energy consumption big country, also is Energy resources countries very in short supply simultaneously, and relevant medium reported once that China was equivalent to consume the energy in the whole world 30% in 2003, and only raw coal has just consumed 15.79 hundred million tons, accounts for 3/4 of total energy.The black dragon that ten hundreds of black smoke chimney produces heavenwards discharging all the time, floating dust, acid rain cause the Nature unbalance, seriously damaging people's health, but the raw coal production of resources is very in short supply on the one hand, waste a large amount of raw coal again because of the combustion technology that falls behind on the other hand, polluting air when burning raw coal again seriously.
On coal exploitation utilized, what at first will solve was to improve combustion efficacy, improves thermal value, reduces pollution exhaust criteria, to adapt to the needs of various burning occasions; Next is only the problems such as waste treatment of opening a mine of utilizing.Fuel for equipment claimed such as industrial used boiler, kilns is the higher fat coal of thermo-efficiency, if reducing coal, long thermal potential of low grade coal and accumulation time do not reach combustion efficacy, need take combustion-supporting measure, but effect is still undesirable, and how to solve low grade coal raising combustion efficacy is the problem that relevant department very pays close attention to always.
Main contents:
The purpose of this invention is to provide a kind of additive for fire coal that makes low grade coal and the lower fire coal of thermo-efficiency improve combustion efficacy.The existing combustion technology that falls behind is seriously being polluted the situation of air again when wasting a large amount of raw coal; provide and both help raw coal and fully burn, save raw coal; can absorb the obnoxious flavour that produces in the raw coal combustion process again, thereby help a kind of additive for fire coal of environment protection.
Technical scheme of the present invention is achieved in that gets 5-30 parts in calcium oxide, 2-10 parts in sodium hydroxide, 3-10 parts in potassium permanganate, 3-15 parts of Manganse Dioxide, 1-5 parts in magnesium oxide, 3-10 parts of SODIUMNITRATE, 1-5 parts in Repone K, 1-5 parts of nitrate of baryta, 3-15 parts of formations of unslaked lime additive formula by weight.Additive is sprayed coal-fired surface, coal-fired thermo-efficiency is improved.Product of the present invention uses emulsifying agent, dispersion agent and permeate agent, fully contacts with coal-fired particle: adopt the catalyzed oxidation metal-salt to increase and add activity, reach perfect combustion.
The emulsifying agent of product of the present invention, dispersion agent, permeate agent are to belong to quick-fried coal water blending fuel.When product of the present invention with after water mixes, when being sprayed at coal-fired going up, just can between the particle of coal, disperse very soon, it is inner and make between coal particle and adsorb mutually to be penetrated into the coal seam.When won ton had the fire coal of this ignition dope to send into sharp burning district, water molecules and organic phase rose up into furnace cavity, form many point of ignition, the particulate of the carbon that does not fire with the space is close, has promoted the burning of free carbon granules, and fiery combustion height has raise, increased intensity of combustion and density, flame temperature also increases.
The invention has the beneficial effects as follows that the putting into operation of this product is able to sufficient utilization with making coals a large amount of in the China's coal-mine destroy stone, coal slime, low grade coal, can realize that two class bituminous coal reach the combustion efficacy and the production capacity effect of fat coal.This has great economy and environmental benefit to the sustainable development of coal in China industry.Environment-protecting efficient additive for fuel coal is nontoxic, pollution-free, nonflammable, non-explosive, pH value is neutral, and no obnoxious flavour produces in the combustion processes.To the boiler non-corrosiveness.Maximum characteristics of the present invention are obvious social benefit, and the business economic considerable benefit is cheap, wide material sources.
