Abstract

The invention relates to the technical field of coal combustion improvers, and discloses a novel combustion improver and a preparation method thereof. The novel combustion improver is composed of deionized water, industrial white oil, industrial ethane, methyl tert-butyl ether, isooctane, xylene, benzene, crude benzene, propylene, raw oil, a pentane foaming agent, methanol, ethanol and wood alcohol, and the preparation method of the novel combustion improver comprises the following steps: S1, preparing materials; S2, primary mixing; S3, carrying out secondary mixing; S4, mixing for the third time; S5, quantitative proportioning. The novel combustion improver can be quantitatively proportioned within the range according to the temperature values of different weather conditions, due to the fact that the quantitative proportions of the proportions are different, the novel combustion improver can adapt to the weather conditions of different temperatures, the combustion-supporting effect ofthe combustion improver cannot be affected by temperature changes, and coal can be effectively prevented from being oxidized and getting stuck in the combustion process; and the heat value of coal combustion can be increased, and the combustion stability is improved.

Description

technical field [0001] The invention belongs to the technical field of coal combustion accelerants, in particular to a novel combustion accelerant and a preparation method thereof. Background technique [0002] Combustion accelerant is a substance that can help combustibles burn under certain conditions and achieve the desired effect. Industrial-grade combustion accelerants are developed to reduce energy consumption and operating costs. The purpose is to save energy and reduce consumption. Adding combustion accelerants to burning coal can improve the combustion rate of pulverized coal and reduce the amount of unburned pulverized coal. [0003] Existing coal-fired accelerants cannot adapt to different weather conditions. When the weather conditions change, the temperature also changes, which affects the combustion-supporting effect of the oxidant, and the flash point of the existing oxidant is low, which may cause When the coal is burned, the card is oxidized and the combust...
