Abstract

A method for providing steam power, comprising a heat pump refrigeration cycle system and a steam power cycle system. The heat pump refrigeration cycle system reuses by recycling latent heat of steam condensation as a driving heat source to drive the heat pump refrigeration cycle system. A high-temperature heat source outputted by the heat pump refrigeration cycle system is used as a heating heat source for the steam power cycle system. A low-temperature heat source outputted by the heat pump refrigeration cycle system is used as a condensation heat source for the steam power cycle system. As such, a minimal amount of mechanical work is consumed in providing a steam power cycle with a heat source and a refrigeration source. The refrigeration source not only can provide the steam power cycle system with a refrigeration source, but can also provide surplus refrigeration to the external, thus implementing electric and refrigeration cogeneration. This solves the problem of economy in an existing power system consisting of a heat pump cycle and a power cycle, thus implementing large-scale green power.

Description

Method for providing steam power

Technical field

The invention relates to a steam power method and belongs to the technical field of steam power.

Background technique

General steam-type power output devices (steam engines, steam turbines) use fossil energy, nuclear energy, solar energy and other energy sources for heating. The burning of fossil energy sources will cause serious environmental pollution. The safety control requirements of nuclear energy devices are high, and solar energy collection devices are highly invested.

CN940254 discloses a power system device comprising a combination of a power circulation system and an absorption refrigeration system, wherein the power system uses absorption refrigeration to provide low temperature cold coal to cool the exhaust steam discharged from the steam power machine, and the technology can be utilized low. The grade heat source provides power. CN940254 also discloses a power system device comprising a power circulation system, a compression heat pump system and an absorption refrigeration cycle system. On the basis of the previous system, the heat pump is used to heat the heat source, thereby improving the power circulation system. The initial temperature makes the power system more efficient than the previous system. CN940254 also discloses a power system with a power circulation system, an absorption heat pump system, and an absorption refrigeration cycle system, and the efficiency of the system is improved compared with the previous system. However, the disadvantage of these three power systems is that the absorption refrigeration system requires at least two heat sources, one high temperature heat source as the driving heat source and one medium temperature heat source as the coolant and low temperature heat source. Generally speaking, the normal temperature environment is a kind of heat source, and an additional driving heat source is needed to make the system work normally. There are many kinds of heat sources. In addition to fossil energy and waste heat, there are different heat sources that use different altitudes of the sea, and different heat sources are provided by using sea water without concentrated water. However, these heat sources are limited by natural conditions. Manually manufacturing different altitudes can be used to create temperature differences, but this method is costly and economically inefficient. There are also solar collectors that provide high-temperature heat sources, but solar collectors require large areas. A space for installing a solar collector. This limits the commercial application of the system.
