Abstract

The invention discloses a low temperature exhaust heat storage system with combined heat and power generation. The low temperature exhaust heat storage system with combined heat and power generation comprises a combustion gas turbine; a gas-gas heater connected with the combustion gas turbine; a steam turbine with a steam boiler being connected with the gas-gas heater; a solar pond connected withthe steam boiler; a condensate water heat exchanger connected with the solar pond, the gas-gas heater and the combustion gas turbine; a cooling tower connected with the condensate water heat exchanger; a heat exchanger with the solar pond; and an absorption refrigerator connected with the heat exchanger. According to the low temperature exhaust heat storage system with combined heat and power generation provided by the invention, the industrial low temperature exhaust heat recovery and the solar heat utilization are combined; and the solar pond is used as a long-acting heat storage mechanism,so that the stability of a heat source is improved, and the temperature fluctuation is small compared with a traditional exhaust heat recovery heat source.

Description

Technical field [0001] The invention relates to a storage system, in particular to a low-temperature waste heat storage system for cogeneration of heat and power. Background technique [0002] Cogeneration has comprehensive benefits such as saving energy, improving the environment, improving heating quality, and increasing power supply. The construction of thermal power plants is an important measure for urban air pollution control and energy efficiency improvement, an important part of central heating, and a public welfare infrastructure that improves the quality of people’s lives. Since the reform and opening up, my country's combined heat and power industry has developed rapidly, which has played an important role in promoting national economic and social development. [0003] Current cogeneration projects are classified into high temperature, medium temperature, and low temperature waste heat based on exhaust heat and condensation heat temperature. Among them, the medium and ...
