Description

Fuel carrying same-light-heat combined cycle gas power device

Technical field:

the invention belongs to the technical field of thermodynamics and thermal dynamics.

The background technology is as follows:

In the process of converting thermal energy into mechanical energy, the most basic requirement is to adopt the simplest possible technical measure to realize the high efficiency of thermal work-for this purpose, and the technicians are diligent.

Fuels are an important option to provide driving thermal loads, of different kinds and different properties; wherein, the temperature of the fuel gas formed by the fuel combustion directly determines the heat-changing work efficiency. Limited by factors such as working principle, in a thermal device adopting high-grade high-quality fuel, larger temperature difference irreversible loss exists in the combustion process. The solar energy forms a high-temperature photo-thermal heat source through a heat collection technical means, and then thermal work is realized through steam power cycle or gas-steam combined cycle, however, due to factors such as a limited working principle, materials, safety and the like, the application value of the high-temperature heat source formed by solar energy collection is not fully exerted, and still a room for improvement is provided.

In order to realize high-efficiency thermal work of high-grade fuel, one conventional technology adopts gas-steam combined cycle consisting of Brayton cycle and Rankine cycle, however, the temperature difference loss of a heat transfer link between the top Brayton cycle and the bottom Rankine cycle is larger, which is not beneficial to the improvement of thermal efficiency; another conventional technique is a combined gas-gas cycle constructed using two brayton cycles-however, the bottom brayton cycle requires deep expansion of the expander and the corresponding compressor, which directly causes difficulty in manufacturing the core components and waste of materials and increase in cost.

Brief description of the high grade fuel and solar energy collection system:

Types of solar energy collection systems include, but are not limited to: (1) the concentrating solar heat collection system mainly comprises a groove type system, a tower type system and a butterfly type system at present; (2) the non-concentrating solar heat collecting system has solar pond, solar chimney and other systems.

(4) There are two main types of heat supply modes of solar heat collection systems at present: (1) the high-temperature heat energy converted by solar energy is directly supplied to a circulating working medium flowing through a solar heat collection system; (2) the high-temperature heat energy converted from solar energy is firstly provided for self-circulation loop medium, and then the self-circulation loop medium is provided for circulation working medium/working medium flowing through the solar heat collection system through a heat exchanger.
