Problems solved by technology
Its comprehensive utilization efficiency is about 80%, the energy utilization rate is not high, and the traditional triple power supply has low adaptability to seasonal energy supply. For example, in winter, due to insufficient cooling demand, the internal combustion engine generator set cannot operate normally. , which greatly affects the stability of the system, so it is necessary to optimize its original system, so as to provide its operation stability and flexibility

The invention provides a large internal combustion engine combined cooling, heating and power optimization system. An internal combustion engine supplies waste heat water to a heat supply system, and supplies waste heat flue gas and waste heat water to a waste heat boiler. The waste heat boiler supplies superheated steam to a steam turbine generator. The steam turbine generator supplies power to an electric refrigerator. Waste heat water is further supplied to a refrigeration system. According to the invention, fuel gas is combusted to work and produce high-grade electric energy, a lithium bromide unit produces chilled water, a heat exchanger produces hot water so as to supply heat to users, and the waste heat boiler produces steam to drive a turbine and a generator to generate electricity. The energy utilization rate is up to 92%.
Description
technical field [0001] The invention relates to the combined cooling, heating and power supply technology of an internal combustion engine, in particular to an optimization system for a large internal combustion engine combined cooling, heating and power supply. Background technique [0002] With the aggravation of environmental problems such as global warming and the depletion of fossil energy, it is very important for our country to improve energy utilization efficiency and change the energy structure. The country clearly pointed out in the "Thirteenth Five-Year" development plan: to accelerate the development of wind energy, solar energy, biomass energy, water energy, and geothermal energy, to develop nuclear power safely and efficiently; to strengthen the construction of energy storage and smart grids, to develop distributed energy, and to promote energy conservation Low Carbon Electricity Dispatch. [0003] At present, there are many distributed energy applications tha...
