Abstract

The invention relates to a co-generation device of a micro gas turbine. The co-generation device comprises the micro gas turbine, a high-speed permanent magnet motor/generator, an adjustment mechanism, a heat regenerator and an afterheat boiler, wherein the high-speed permanent magnet motor/generator is directly connected with the micro gas turbine; the gas output end of the micro gas turbine is communicated with the heat regenerator and the afterheat boiler respectively; the adjustment mechanism comprises a heat regeneration valve and an afterheat boiler valve; and the air input/output end of the heat regenerator is communicated with the micro gas turbine. By adopting a structural form with the heat regenerator and the afterheat boiler, the valves can be adjusted according to different energy demands of a user for power and heat, and the flow of high-temperature gas passing through the heat regenerator or the afterheat boiler can be changed; and therefore, the demand for energy can be adjusted.

Description

technical field [0001] The invention relates to a heat and power cogeneration device, in particular to a micro gas turbine heat and power cogeneration device. Background technique [0002] Micro gas turbine combined heat and power system is a new type of distributed energy supply system with high energy utilization rate, and its power range is 15~300kW. In recent years, with the changes in energy and power demand and environmental protection requirements worldwide, micro gas turbines have been highly valued by relevant departments of electric power, power, national defense and military industry in various countries. Internationally, countries such as the United States, Sweden, and the United Kingdom have developed and produced micro gas turbines, and some domestic universities, scientific research institutes, and enterprises are also conducting research and development in this area. [0003] The distributed energy supply system with micro gas turbine as the core is one of t...
