Heat storage system utilizing heat accumulator to be combined with solid heat storage body

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.
