Abstract

The invention provides a solar thermal power generation system of an integrated double-hearth biomass boiler. The solar thermal power generation system comprises a solar heat collection subsystem, a double-hearth biomass combustion subsystem and a power generation subsystem. The double-hearth biomass boiler is adopted, so that the system reliability and safety are improved. Solar energy and biomass energy supplement each other to achieve power generation, the power generation efficiency is improved, zero emission of carbon is achieved in the whole cycle period, and high efficiency and cleanliness are achieved in the power generation process.

Description

technical field [0001] The invention relates to the technical field of renewable energy utilization, in particular to a solar thermal power generation system integrating double-chamber biomass boilers. Background technique [0002] With the rapid development of the current national economy, the demand for energy is increasing day by day. At the same time, the environmental problems caused by the massive use of fossil energy are becoming increasingly severe. Therefore, it is of great significance to replace fossil energy with renewable clean energy such as solar energy and biomass energy. [0003] Solar energy is an abundant and clean energy source. Although the energy projected by solar energy to the earth's atmosphere is only 1 / 2.2 billion of its total radiant energy, the total amount of solar energy projected is already very high, and the total energy radiated to the earth per second is equivalent to 5 million tons of standard coal. Among them, 2 / 3 of my country's land h...
