The invention relates to a vertical superheated steam heat storage device which comprises a base and a heat storage device body installed on the base. A steam jet heater is installed at the bottom in the heat storage device body and is connected with the inner end of a heat filling port. A heating cylinder heater is installed in the middle of the heat storage device body. A high temperature and high pressure superheater is installed on the upper part inside the heat storage device body. A Laval pipe reheater is installed above the heat storage device body. The vertical superheated steam heat storage device is small in occupied area, and can output superheated steam with the degree of superheat of 50-100 DEG C and can be merged into a superheated steam heat network or output superheated steam with the degree of superheat of 3-5 DEG C and 10-15 DEG C. The vertical superheated steam heat storage device is wide in application range and strong in using agility. When the vertical superheated steam heat storage device is used in a heat supply or heat using system with large heat load fluctuation, the combustion efficiency of a boiler can be improved, the operating heat efficiency of a unit can be improved, and the utilization ratio of energy sources can be improved, so that the vertical superheated steam heat storage device has a huge benefit of energy conservation and emission reduction.
Description
technical field [0001] The invention relates to a thermal power device, in particular to a vertical superheated steam heat accumulator. Background technique [0002] The steam accumulator is mainly used in heat supply and heat use systems with fluctuating heat loads. It stores the heat of high-temperature and high-pressure steam in the water in the container to make it supersaturated water, and generates continuous secondary steam through flash evaporation. The traditional steam heat accumulator can only output saturated steam and has a large water content, so it cannot be used for saturated steam power generation. Moreover, saturated steam is easy to condense into water, which cannot be transported over long distances, let alone merged into the superheated steam pipe network. [0003] The previous patent "Automatic micro-superheated variable pressure heat accumulator" (authorized publication number CN200952909Y) provides a horizontal heat accumulator that can output superh...
