The efficiency of operation of gas pumping units (HPA) is characterized both by their technological parameters and the technical state of HPA as a whole. If a number of methods and technical means for their implementation have been developed to control the technical condition of the main units of HPA (power bearing elements, blades, piping, etc.), then this important unit of HPA does not pay much attention to the combustion chamber. At the same time, the technical condition of the combustion chamber determines not only the efficiency of HPA operation, but also leads to environmental pollution by its exhaust gases, which contain harmful substances. In this connection, the task of studying the HPA combustion chamber from the point of view of monitoring its ecological and technical state is relevant. To solve this problem, we analyzed the results of heat engineering, vibration, and environmental- technical surveys of various types of HPA and with different periods of operating time at the Prikarpattransgaz Group of Mines over the past five years. The work presents the obtained results, in particular, on the concentration of harmful emissions in exhaust gases containing O2, CO2, CO, NO2, NO2, and also NOx (in eq. NO2), which make it possible to substantiate their quantitative and qualitative composition. It has been established that the most harmful emissions from the operation of compressor stations are carbon oxides (53%) and nitrogen oxides (24.5%). The dependences of changes in the technical state of the combustion chamber on the quantitative and qualitative composition of its harmful emissions and their impact on the technical and economic performance of HPA are established. The results of calculations of indicators of reliability of control, reliability and efficiency of control of the ecological and technical state of the HPA combustion chamber are given. The obtained results allow us to recommend the use of single-channel analyzers to measure these emissions and integrate them into the monitoring system of the environmental-technical state of HPA.
