Embodiment Construction

[0023] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0024] The working process of the original power generation system is: the fan 7 transports the gas in the heating medium source pipe 12 to the heat transfer medium generating device 1, and the heat transfer working medium generated by the heat transfer working medium generating device 1 is transported through the heat transfer working medium The pipe 13 is sent to the steam turbine 2, and the steam turbine 2 drives the generator 3 to generate electricity. After the heat loss of the heat transfer medium, it becomes condensed water through the condenser 10 and sent to the condensed water tank 4. The thermal medium generating device 1 forms a cycle.

[0025] The heating medium source pipe 12 is divided into two outputs after passing through the fan 7, one of which is connected to the auxiliary heater 6, and the other is ...

Abstract

The invention discloses a heat storage system utilizing a heat accumulator to be combined with a solid heat storage body. The heat storage system comprises a solid heat storage device, the heat accumulator, an auxiliary heater and a heat release passage, wherein the solid heat storage device, the heat accumulator and the auxiliary heater are sequentially connected to a heat transfer working mediumconveying pipe of an original power generation system, and the heat release passage is formed by connecting pipelines; and for the heat release passage, the heat accumulator is correspondingly connected with the auxiliary heater and a condensation water tank of the original power generation system, and the auxiliary heater is connected to the solid heat storage device through a pipeline in a communicating mode. According to the heat storage system, by-production coal gas is utilized, and the auxiliary heater is arranged so that a heat transfer working medium output by the solid heat storage device can be guaranteed to be well fused with a heat transfer working medium generated by a heat transfer working medium generation device, and then is conveyed to a user.

Description
