Abstract
The invention discloses a coal combustion accelerant with a good desulfurization effect. The coal combustion accelerant comprises an accelerant and a desulfurizer, wherein the desulfurizer is methyl propoilate, the weight of which is 1-2% of the total weight. The accelerant provided by the invention can obviously save the coal combustion by 5-25%, has a particular accelerating effect for the coal combustion with a low calorific value and low volatile matters and can largely reduce the sulfur content in the gas by 35-65%. The accelerant is simple in using method and is only sprayed or dipped onto the coal traveling belt through a metering pump. Moreover, the accelerant has a burn-out rate of over 99%, almost does not have a trace of residues, and can not increase slag discharge and exhaust gases.
Description
Technical field
The present invention relates to a kind of coal burning that is used for, improve the coal burning promotor of efficiency of combustion.
Background technology
China is a producing coal and uses coal big country that since the establishment of the nation, coal accounts for about 75% in the disposable energy expenditure of China constitutes.In long period, coal will be topmost role in China's energy.Building a resource-conserving and environment-friendly society is China's long-range mission of present stage.Therefore, rationally utilize the efficiency of fire coal of coal resources, raising coal, but have high economic benefit, have the important social meaning again.The sulphur that gas-fired discharged is the principal element of topsoil, and Chinese patent CN102127382 discloses charcoal oxygen based raw material coal and promoted incendiary material, and it reduces, and sulphur content is 29-60% in the coal gas.
Summary of the invention
The purpose of this invention is to provide a kind of desulfurization effect, reduce that sulphur content is the coal burning promotor of 35-65% in the coal gas.
The technical scheme that the present invention adopts is: the coal burning promotor of desulfurization effect, comprise promotor and sweetening agent, and it is characterized in that said sweetening agent is: the propynoic acid methyl esters, the propynoic acid methyl esters accounts for the 1-2% of gross weight.
Described promotor comprises emulsifying agent, catalyzer, dispersion permeate agent.
As further improvement of the present invention, said emulsifying agent is polyoxyethylene glycol, poly glycol monomethyl ether.
As further improvement of the present invention, described catalyzer is aluminium acetylacetonate, cycloalkanes mangaic acid.
Beneficial effect of the present invention is:
Promotor of the present invention is liquid suspension liquid body, is easy to store, transport, and operational safety, addition is few;
Coal burning saving rate of the present invention is obvious, and between 5-25%, especially the coal burning facilitation effect to low heat value, low-volatile is obvious.
The present invention can significantly reduce sulphur content in the flue gas, and the reduction amplitude is between 35-65%.
Method of use of the present invention is simple, only need on the Coal Transport belt, spray or drip with volume pump to get final product;
Self burn-off rate of the present invention is more than 99%, and almost none residue can not increase deslagging and tail gas.
