Abstract

In this paper an attempt is a comprehensive presentation of the problem of methane emissions from ventilation air from the mines to the atmosphere and possible solutions are suggested. Methane is released during excavation work in coal mines is a big problem in terms of safety and environmental protection. At the same time, it is a further potential source of energy that has been not yet used on a larger scale [1]. In order to properly identify ventilation air methane as an energy source will be presented its properties and possible complications due to the nature of this type fuel. A very important part will also determine the methane potential from ventilation air in Poland [2]. The work provides an overview of available technology for methane utilization from ventilation air as a fuel. Important from the point of view of the rest of the work is presentation of catalytic flow-reversal reactor technology created in Poland. Main objective of the topic is the development and modeling of heat recovery system cooperating with the IUMK-1000 installation [3]. The premise is the electricity production and also heat for central heating when it is technically feasible and justified in economic terms. Different concepts of heat recovery are modeled by the IPSE-Pro software. Then an analysis of the efficiency and performance of the proposed system is carried out. Based on the results, an individual concepts cycle works were analyzed and assessed and the best solutions possible for implementation on an industrial scale is selected.

Summary

Introduction

Authority absolute methane-bearing, that is the sum of the emittedmethane from coal seams per year, remainedstable (approx. 830 million m3 CH4) in recent years. Authority absolute methane-bearing, that is the sum of the emittedmethane from coal seams per year, remainedstable 830 million m3 CH4) in recent years. Relative methane-bearing (the amount of methane per coal tonne) is not subject to the higher fluctuations and is approx. Ventilation air methane in Poland is about 70 % of the total methane emission from coal seams corresponding to 600 million m3 of methane emitted together with the removable ventilation air. In the world, excluding pilot plant and a small number of commercial installations, it is not used in any way and is the only source of harmful emissions. E3S Web of Conferences 10, 00094 (2016)
