NUMERICAL AND EXPERIMENTAL MODELING OF LOW-CALORIE GAS FUELS COMBUSTION PROCESSES

Abstract

Methane, which is found in coal seams, has long been seen as an alternative to imported natural gas. Capturing that victorious methane can immediately increase the versatility of the production of footwear, increase the safety of the minds of the workforce, and change the negative impact to dovkillya. And yet, there are low technical and technological folds, which galmuyut the development of the type of bottle and utilization of methane.One of the main directions of extraction of coal mine methane is the generation of thermal energy in boiler houses and other heat generators. However, this type of paliva is unstable in concentration and important, due to the fact that the technical riven has the same characteristics. The current development of technology and technology, in general, allows you to successfully improve the nutrition of methane. There are very few data on environmental and energy indicators for the process of scalding with different palnikov outbuildings.In the coal mines of the Donbass, there is a widespread stagnation of the boiler room with bottom (hollow) toe shoes. Further indications of scalding with different design features of this type of stokers will help to improve nutrition by reducing the chemical insufficiency of scalding gas and increasing the thermal pressure of the boiler. It is shown that the computer simulation and re-verification of the efficiency of coal mine methane scorching in scorching boilers from the stoking of bottom (hollow) stokers is shown to be possible.In the robot, an experimental simulation of the process of burning coal methane in the bottom of the burners of a modernized design was carried out, and tests were carried out on the distribution of medium-mass parameters in the gas at the exit from the fire line from the vicarious grids. And also, an analysis of stationary watering of the average characteristics of the flow fluidity, temperature, concentration of components, nitrogen oxide and nitrogen oxide fluidity was carried out.
