Development of autonomous energy supply of a mobile surface degassing plant.

Abstract

Currently, in connection with the difficult situation with energy supply, issues related to the application of new measures to conserve energy resources as well as the introduction of new promising technologies using alternative energy sources, such as mined methane, have gained great importance. The problem of methane from coal deposits is of particular importance. This problem primarily concerns the safety of miners' work, methane production as an alternative source of energy resources, and solving environmental problems related to methane emissions into the atmosphere of coal mining enterprises. The problem of reducing the efficiency of degassing is caused by the long length of the degassing pond and the depth of cleaning operations. The use of a mobile surface degassing unit makes it possible to effectively carry out degassing and achieve significant volumes of extracted gas with a methane content of up to 80%, but high costs of electricity complicate its operation. Therefore, the paper proposes an autonomous power supply for a mobile surface degassing plant. For the autonomous power supply of a mobile surface degassing plant, it is advisable to use an electric generator since an uninterrupted supply of electricity is important. Gas power plants are widely used in industrial enterprises. In accordance with the power consumption of the electrical equipment of the mobile surface degassing plant, the work justified and selected a gas power plant and electric power equipment for the autonomous power supply of the mobile surface degassing plant. The gas-piston power plant is designed for the production of electrical energy and can be both the main and backup source. As a fuel, mainline natural gas with an average supply pressure or methane mine gas is used. The basic configuration of the power plant is a liquid-cooled gas-piston engine based on a diesel unit. A technological scheme for connecting the gas power plant to a mobile vacuum pumping unit and its power supply scheme has been developed, which will increase the safety of cleaning works, solve the issue of methane utilization, significantly reduce electricity costs, and improve the environmental situation in the industrial region.
