Abstract

The invention discloses a solar power generation method and a solar power generation system taking a biomass boiler as an auxiliary heat source. The system comprises a solar condensation heat collecting device, a biomass boiler device and a steam turbine generator system, wherein the solar condensation heat collecting device takes water as a medium and is combined by adopting medium-pressure solar vacuum heat collecting pipes in a series-parallel matrix; the outlet of the solar condensation heat collecting device is communicated with the bottom of a steam pocket of the biomass boiler; and the steam outlet of the steam pocket of the biomass boiler is connected with a cylinder of a steam turbine generator. A de-aerator and a water supply pump are connected in series in the water inlet pipeline of the solar condensation heat collecting device. A steam re-heater is connected in series in the connected pipeline of the steam outlet of the steam pocket of the biomass boiler and the cylinder of the steam turbine generator; the steam re-heater is connected to the cylinder of the steam turbine generator; and the steam re-heater is placed in a flue of the biomass boiler. A water supply tank is a desalting water storage tank, and the desalting water storage tank is connected with the de-aerator through the water supply pump and connected with the outlet of the solar condensation heat collecting device through a first control valve.

Description

technical field [0001] The invention relates to a solar power generation method and system using a biomass boiler as an auxiliary heat source, belonging to the field of new energy power generation, in particular to biomass and solar power generation clean energy. Background technique [0002] With the decreasing reserves of traditional fossil energy (coal, oil, natural gas) and the environmental pollution caused by the use of fossil energy, which directly threatens the survival and development of human beings, it has become a national priority to attach importance to and develop renewable and environmentally friendly energy. Government consensus. Solar energy has wide distribution, unlimited reserves, clean collection and utilization, CO 2 The advantages of zero emissions have attracted widespread attention. [0003] However, for a long time, the large-scale development and utilization of solar energy has been costly and cannot compete with conventional fossil energy econo...
