Abstract

The present invention provides a method for calculating the ignition period of coal piles and a coal yard anti-spontaneous combustion monitoring system. The method includes: according to the coal pile temperature, the height of the coal pile, the distance from the top of the coal pile to the center, the The stacking angle of the pile, the circumferential angle of the coal pile, the density of the coal, the carbon content of the coal, and the volatile content of the coal are used to calculate the heat loss value; using the temperature of the coal pile, the heat loss value, the specific heat capacity of the coal, The thermal conductivity of coal is used to calculate the ignition period of coal piles.

Description

technical field [0001] The invention relates to the field of computer data processing, in particular to a method for calculating the ignition period of coal piles and a coal yard anti-spontaneous combustion monitoring system. Background technique [0002] Spontaneous combustion of coal is an objective phenomenon that exists in nature. It is known from chemistry that spontaneous combustion is a phenomenon in which substances are oxidized in the air and burns automatically, and combustion is a chemical phenomenon in which substances are violently oxidized to emit light and generate heat. It can be seen that coal spontaneous combustion is the result of physical and chemical effects of coal in contact with oxygen in the air for a long time. [0003] In order to change the traditional open-air strip coal yard, it is necessary to increase the site area accordingly to increase the coal storage capacity and reduce the pollution of the surrounding air and water sources. The closed ci...
