Abstract

The invention discloses a combined heat and electricity generation system formed by the combination of a fuel cell and a gas turbine. The system comprises a feeding subsystem, a preheating subsystem, a fuel cell subsystem, a reforming subsystem, a gas turbine power generation subsystem and a waste heat utilization subsystem. A mixing combustion subsystem is provided between the fuel cell subsystem and the gas turbine power generation subsystem, and the subsystems are mutually connected with each other to form the combined heat and electricity generation system of cycle combination. According to the invention, the supercharged melted carbonate fuel cell is organically combined with the micro gas turbine to form the quality-exchanged combined cycle system, the power density of the system is high, and the waste heat recycle is fully and effectively carried out, so the whole energy utilization rate is improved as possible.

Description

technical field [0001] The invention relates to a heat and power cogeneration system, in particular to a heat and power cogeneration system based on a combined cycle of a fuel cell and a gas turbine. Background technique [0002] In order to improve energy utilization efficiency, a variety of combined heat and power systems that integrate power generation and heat energy have been developed. One of the more cutting-edge systems is the use of fuel cell technology. This technology converts the chemical energy of combustion directly into electrical energy. Among them, the molten carbonate fuel cell (MCFC) has the advantages of high efficiency, low pollution, etc., and has high-grade waste heat, so that it can form a combined cycle system with other power devices. , thereby greatly improving the overall efficiency of the system. [0003] Some power generation and / or heating systems based on fuel cells have been proposed at home and abroad, using natural gas, coal gas, etc. as f...
