Abstract
This paper deals with the control of the output power gas temperature at the Main Heat Exchanger (MHE). The MHE is the basic part of the Flexible Energy cogeneration System (FES) with the combined Brayton - Rankine cycle, which is designed and constructed at Vitkovice Power Engineering JSC. The FES burns solid fuel and generates electrical energy and thermal energy. The standard temperature control at MHE has two goals. The first control task is the protection of the heat transfer surfaces of the MHE against overheating. The second control task is the stabilization of the temperature of power gas at the output of the MHE which is performed, in principle, by the change of the flow rate of air generated by the compressor and by the change of the flow rate of fuel at the inlet of the FES combustion chamber. In this paper, the control of the temperature of the power gas without the overheating of the heat transfer surfaces of the MHE will be described and analyzed.
