Problems solved by technology

[0003] Existing methods of increasing coal combustion speed have certain disadvantages in use. Modern coal combustion mainly uses boilers as the main load, and most of them use iron as the main material of coal combustion application boilers. Long-term combustion of coal will cause boilers to Internal carbonization, combined with the erosion of moisture in the coal composition, increases the loss rate of coal boilers
At the same time, too much water in the coal is not conducive to the post-processing of coal and coal transportation, and will reduce the volume ratio of coal in the boiler. Secondly, when the existing coal is burned, the surface of the coal is only treated by a catalyst. It needs to absorb a large amount of heat energy to reach the ignition point, so before the ignition point is reached, the coal cannot be fully burned, producing toxic carbon monoxide gas, and at the same time the burning time of coal, for this reason, we propose a method to increase the burning speed of coal

Abstract

The invention discloses a method for increasing the burning speed of coal, comprising the following steps: immersing: immersing coal in a soaking pool for immersing for 20 min, and adding diesel oil and a combustion improver mixed liquid, wherein the combustion improver mixed liquid consists of, in parts by weight, 7 parts of alkylphenol polyoxyethylene. According to the method for improving the burning speed of coal, firstly heat stability and heat conduction are combined mutually during coal combustion, the coke yield is reduced when coal resources are used for coking, and the heat generation duration is improved during coal combustion; and secondly, when burning of coal, heating of the coal can be speeded up, the temperature can quickly enter a burning point of coal, further the burningspeed of coal is improved, at the same time emission of harmful gases is reduced when coal is burned at a low temperature, carbon ash on the surface of coal can be removed to enable internal coal tobe in contact with external air for accelerating oxidation of coal and further improving the combustion of coal, and thus better use prospects are brought.

Description

technical field [0001] The invention relates to the technical field of coal combustion, in particular to a method for increasing the coal combustion speed. Background technique [0002] Coal, known as black gold and food for industry, has been one of the main energy sources used by the human world since the eighteenth century. The reserves of coal are huge, and with the rapid development of science and technology, new technologies such as coal gasification are becoming more and more mature. Widely used, coal will surely become one of the irreplaceable energy sources in human production and life; [0003] Existing methods for increasing coal combustion speed have certain disadvantages in use. Modern coal combustion mainly uses boilers as the main carrier, and most of them use iron as the main material of coal combustion application boilers. Long-term combustion of coal will cause boilers to Internal carbonization, combined with the erosion of moisture in the coal constituent...
