THERMOCHEMICAL HEAT RECOVERY IN A GAS TURBINE PLANT

Natural gas every year wins an increasing share in the global fuel balance. Countries where cheap natural gas is available are seeking to increase the efficiency of its use in order to increase the volume of its use. One of the most promising methods for increasing the efficiency of natural gas is the heat recovery of gas waste. The subject of the study is a gas turbine plant due to the fact that the number of power plants with gas turbines tends to increase. In this paper, options for increasing the efficiency of using natural gas in gas turbines at a constant flow rate are investigated. Variants of implementation of thermochemical heat recovery of gas wastes based on steam reforming of methane and thermal heat recovery of gas wastes based on steam generation are considered. The results of a study based on a mathematical model of a gas turbine plant using thermal and thermochemical waste gas heat recovery are presented. A constructive calculation of the methane steam reforming reactor has been carried out. The design and regime parameters of the heat exchanger are determined. A 3D-model of the conversion reactor has been developed, which provides high gas density and the possibility of thermal elongation of heat exchange tubes
