Source end coupled solar energy gain type coal-fired power plant boiler

Abstract

The invention discloses a source end coupled solar gain type coal-fired power plant boiler. The boiler comprises a solar heat collector, a high-pressure heater, a combustion chamber, a deaerator, a water feeding pump and a regulating valve, wherein an outlet of the solar heat collector and an outlet of the high-pressure heater are combined through a pipeline and then communicate with an inlet of the combustion chamber, an outlet of the deaerator is divided into two paths after passing through the water feeding pump, one path communicates with an inlet of the solar heat collector through the regulating valve, and the other path communicates with an inlet of the high-pressure heater. The boiler can realize organic coupling of light energy and the boiler.

Description

technical field [0001] The invention relates to a boiler, in particular to a source-end coupled solar energy gain type coal-fired power plant boiler. Background technique [0002] my country is the world's largest carbon emitter, accounting for 27.2% of the world's carbon emissions. In order to achieve the established goal of "carbon peaking and carbon neutrality", the power industry must not only develop new energy power stations such as wind power and photovoltaics with zero carbon emissions as future incremental power, but also have to deal with huge stocks and high carbon emissions. Traditional coal-fired thermal power plants undergo carbon reduction transformation. From the perspective of scale, the coal-saving and carbon-reducing effect and impact of stock transformation will be far greater than incremental replacement. In addition, the cost of technological transformation is far less than the investment in new wind power plants and photovoltaic thermal power plants....

AI Technical Summary

Problems solved by technology

The layout of the dual power stations has undoubtedly resulted in a great waste of investment. Adhering to the original intention of reducing carbon emissions, new large carbon emitters such as traditional coal-fired power plants have been added.

[0004] If new energy forms such as wind energy and solar energy can be organically combined with existing coal-fired boilers in existing power stations with the help of light-to-heat and wind-to-heat conversion devices, it is undoubtedly true that new energy can help coal-fired boilers save coal and reduce carbon emissions. It has opened up a new direction of harmonious coexistence of natural energy utilization and traditional thermal power, but the prior art does not give a similar disclosure
