Problems solved by technology

No. 200910175550.6 patent application disclosed the combined heat and power steam turbine technology, which can increase the temperature of the latent heat of condensation to 100°C without increasing the coal consumption of power generation. Can not be used; even in the winter and spring heating season, when the weather is warm for a period of time, the latent heat of condensation of the steam turbine cannot be fully utilized
Although this circulation method avoids the accumulation of cold water in the hot water pipe 29, a return pipe is added, and the use of the circulation pump and the power consumption of the circulation pump are also increased.

Abstract

The invention discloses an energy accumulation heat supply system, an application mode thereof and a hot water supply device. The heat energy or the cold energy of a hot source or a cold source stored by a heat insulation liquid warehouse larger than fifty thousand cubic meters is used for supplying heat or supplying cold, so the usable heat energy or cold energy generated by the heat source or the cold source in four seasons in a year can be fully utilized. The heat supply hot water device of the invention can avoid the cold water accumulation and storage in a hot water pipe under the condition of not using a cyclic water pipe and a cyclic pump.

Description

1. Technical field [0001] The invention belongs to the heat supply technology utilizing heat accumulated in heat storage materials. 2. Technical background [0002] From theory to practical application in the existing heat supply field, the function of heat storage is limited to peak regulation. As described in the 2005.6 issue of "District Heating" magazine "Application of hot water accumulators in district heating systems": the application of accumulators in combined heat and power heating systems is mainly used to balance heat loads (eliminate peaks) . The combined heat and power steam turbine technology disclosed in patent application No. 200910175550.6 can increase the temperature of the latent heat of condensation to 100°C without increasing the coal consumption of power generation. It cannot be utilized; even in the heating season of winter and spring, when the weather is warm for a period of time, the latent heat of condensation of the steam turbine cannot be fully...
