Problems solved by technology
Even so, it cannot fundamentally solve the corrosion problem inside the equipment
Boiler blowdown during operation, not only a large amount of high-temperature and high-pressure water vapor and water are lost to cause huge waste, but also produce high noise and seriously pollute the environment

Embodiment Construction
[0033] First, the process at the beginning of the startup:
[0034] 1. Chemically clean the related equipment of thermal power generation.
[0035] The reason is that boilers and other equipment are protected with normal temperature protective materials such as grease before they are put into use, but these protective agents will cause serious corrosion to the equipment at high temperatures; In the case of long-term downtime, rust and other impurities are easily generated inside the equipment.
[0036] American experts have drawn the following conclusions based on years of research: If the metal surface is clean, corrosion will not occur. Once the deposits accumulate, corrosion will begin, and the rate of corrosion is proportional to the increase in temperature. The increase in temperature is caused by deposition. caused by things.
[0037] The purpose of chemical cleaning is to remove impurities on the metal surface, keep the metal surface clean, and form a protective layer...

The invention discloses a process flow in a power plant combining low temperature solar thermal power generation and thermal power generation. The process flow is characterized in that as the hot water which is generated by a solar water heater and is used for generating electricity is combined with the thermal power generation, the problem that difficult power generation in overcast and rainy day generally exists in the solar electrical energy generation for a long time is solved. The invention is originated in the world, utilizes the hot water generated by the solar water heater to generate electricity as well as the advantages of large thermal capacity of the water, and is provided with a huge insulating heat storage water sump. Therefore, the process flow replaces electricity storage by heat storage, so as to generate electricity according to the needs and lead the aqueous vapor to completely circulate; furthermore, the fuel in one old fuel electric plant can be used for generating electrical power of more than three plants. The invention not only reduces the pollution, but also has the cost of power generation to be one third of that of the old fuel electric plant, thus having promotion value.
Description
technical field [0001] The invention relates to the technical fields of solar power generation and environmental protection. More specifically, it involves the world's first low-temperature solar thermal power generation technology. Background technique: [0002] At present, the technology of using water vapor to drive turbogenerators to generate electricity is the most important power generation technology in the world, accounting for more than half of the world's total power generation. For example, thermal power generation and nuclear power generation use water vapor to drive turbogenerators to generate electricity. . [0003] Thermal power generation is the world's largest source of pollution and the largest industrial water consumer; the emission of greenhouse gases ranks first in the world. There are sufficient evidences to prove that: global warming, increase of acid rain, increase and intensification of disastrous weather, mass extinction of species, mass pollution...
