Embodiment Construction

[0019] As shown in the figure, a solar heating system is arranged between the desalination treatment device 16 and the deaerator 15. The solar heating system includes a solar heater, a water inlet pipe 5 and an outlet pipe 4, and the water supply pipe is disconnected at the position before the deaerator A bypass valve 10 is set, and two branch pipes are arranged on both sides of the bypass valve. The solar heating system water inlet pipe 5 is connected before the valve, and the solar heating system water outlet pipe 4 is connected after the valve. The heater is a solar heater 3 and a concentrating solar high-temperature heater 2 connected to each other, and the concentrating solar high-temperature heater 2 includes a high-temperature vacuum tube 18 and a Fresnel concentrator 19 connected thereto and a thermal expansion compensator 17 .

Abstract

The invention relates to a complementary solar energy and fuel coal heating system. The technical scheme includes that the complementary solar energy and fuel coal heating system is characterized in that a solar heating system is arranged between a desalting device and a deaerator and comprises a solar heater, a water inlet pipeline and a water outlet pipeline, a water supplement pipe is disconnected at a position, provided with a bypass valve, in front of the deaerator, two branch pipes are arranged on two sides of the bypass valve, and the water inlet pipeline of the solar heating system is connected with the branch pipe in front of the valve while the water outlet pipeline of the solar heating system is connected with the branch pipe behind the valve. Conversion of solar energy into heat for heating desalted water and a system converting electric coal into heat for heating the desalted water are matched and complementary in use, and accordingly electric coal consumption is reduced, effective use of energy sources is guaranteed, and environmental protection, energy saving and consumption reduction are achieved.

Description

technical field [0001] The invention belongs to the field of thermoelectricity, in particular to a solar energy and coal-fired complementary heating system. Background technique [0002] At present, most of the domestic thermal power companies still use the original desalinated water heating mode. After the tap water is treated, it is transported to the deaerator through the pipeline, heated with steam, and then fed to the high-temperature heater through the feed water pump to heat up and then input to the boiler. In the heating chain before entering the furnace, the water pressure is low and the water temperature difference is large. Generally, the temperature difference is about 80 degrees. This temperature difference requires a large part of the coal to be converted into steam for heating. Coal resources are an indispensable non-renewable energy that has a huge impact on human beings. At present, coal resources are already in short supply, and the price has exceeded ten ...
