Description
Technical Field
[0001] The invention relates to the technical field of thermal power plants, in particular to a quantitative feeding device for a coal-fired boiler in a thermal power plant. Background Art
[0002] As a common energy conversion device, boilers play a vital role in fields such as power generation and power supply. Their operating mechanism relies on the continuous supply of fuel into the furnace to ensure stable heat output. Taking coal-fired boilers as an example, regular and appropriate addition of coal is the key to maintaining its efficient operation.
[0003] However, the current feeding system used in coal-fired boilers has obvious deficiencies in design, which is specifically manifested in the lack of precision in controlling the amount of coal feed. In actual operation, the regulation of the feeding amount often relies on the personal experience and intuitive judgment of the operator, rather than on precise measurement methods. This extensive control method not only leads to a significant waste of coal resources, but also invisibly raises the operating cost of the boiler, which runs counter to the modern concept of energy conservation and emission reduction. Therefore, a more scientific and reasonable feeding mechanism is urgently needed to optimize the fuel supply process of coal-fired boilers.
