摘要：

Based on the data of a physical experiment, the possibility of increasing the efficiency of combustion of fuel in power plants with the use of a multipoint plasma ignition of a fuel mixture in a cylindrical combustion chamber of such an installation by a subcritical streamer discharge initiated on the combustion chamber surface by a half-wave resonator is discussed. The dependences of the flame front propagation time and the rate of pressure increase in the combustion chamber on the initial pressure and composition of the fuel mixture characterized by the fuel excess coefficient, were studied Based on the results of measurements, the optimal fuel excess coefficient was determined, which provides the highest pressure and the highest rate of pressure increase in the combustion chamber during streamer ignition of fuel in it.
