MATHEMATICAL MODEL OF A STEAM TRACT OF A MULTI-FUEL BOILER UNIT FOR THE DISPOSAL OF COAL MINT METHANE. Stasevich R.K. Abstract Thanks to the creative efforts of the students and workers of IGTM NAS of Ukraine, we take the leading place in the world practice of methane utilization in the coal mine. The issue of recycling methane ventilation jets (MVS), with a percentage less than 1%, is not being solved. The purpose of the work is to ensure the safe operation of explosive technological processes in the utilization of methane gas in metallurgy. Steam boilers belong to a wide class of control objects, static and dynamic characteristics, which vary widely in advance in an unforeseen manner. The steam capacity of the boiler unit is regulated in accordance with the load being consumed by influencing the supply of fuel and air to the combustion chamber, which is necessary for combustion. The condition determining its failure rate from exceeding the permissible vapor pressure is a violation of the balance between the steam being consumed and the steam being generated. The main condition for gas consumption is the maximum use of mine methane.The boiler unit as an object of regulation of pressure or steam consumption can be simplified to be represented in the form of two series-connected elements: the furnace and the evaporative device of the boiler. The economizing and steam- superheating sections of the boiler are conditionally accepted by those entering the evaporation circuit. The example of a steam boiler proposed for the utilization of coal mine methane shows the mathematical description of the explosive technological process of methane utilization in the form of differential equations and complex transfer function that creates the basis for creating an automatic control system for a boiler that ensures the safety of its operation. A structural solution of the tricogeneration station on the basis of a multi-fuel boiler, which can safely and energy efficiently utilize not only the natural gas of coal deposits but also low-concentration mine methane, has been developed. Gained algorithm will serve as a basis for the development of the mathematical support of the system for safe and energy-efficient management of a multi-fuel boiler utilizing coal mine methane.
