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 accumulation system combining an auxiliary heating device, a heat accumulation device and a solid heat accumulation body. The system involves the solid heat accumulationdevice, the heat accumulation device, the auxiliary heating device, and a heat release passage, wherein the solid heat accumulation device, the heat accumulation device, the auxiliary heating deviceare sequentially connected to a heat transfer working medium conveying pipe of an original power generation system, the heat release passage is formed through pipeline connection and is characterizedin that the heat accumulation device is connected with the solid heat accumulation device and a condensation water tank of the original power generation system, and the solid heat accumulation devicecommunicates with the auxiliary heating device through the pipeline. According to the system, byproduct coal gas is utilized, and through the arrangement of the auxiliary heating device, it can be ensured that the heat transfer working medium output by the solid heat accumulation device and the heat transfer working medium generated by a heat transfer working medium generating device can well fuseand be conveyed to a user.

Description

【Technical field】 [0001] The invention belongs to the technical field of solid heat storage, and in particular relates to a heat storage system in which an auxiliary heater is combined with a heat accumulator and a solid heat storage body. 【Background technique】 [0002] The steam accumulator is a steam container with water as the heat storage medium.
