Abstract

The invention belongs to a coal type real-time switching device and method during coal supply in the thermal power generation process. The coal type real-time switching device comprises a first coal bunker, a second coal bunker, a screw conveyor, a coal feeder and a coal mill, a conveying passageway is arranged between the first coal bunker and the second coal bunker, a gate is arranged on the conveying passageway, and the screw conveyor is arranged at the position, arranged on the first coal bunker, of the conveying passageway. One end of the conveying passageway is connected with the first coal bunker, a coal feeding passageway is arranged at an outlet of the second coal bunker and connected with the coal feeder, the other end of the conveying passageway is connected with the coal feeding passageway, and the coal feeder conveys fuel coal to the coal mill. By means of the coal type real-time switching device and method, flexible coal blending can be conducted, the problems that current thermal power plants are frequent in daily peak regulation and large in peak regulation amplitude are solved, and the technical solution which is safe, economical, feasible and wide in application range is achieved.

Description

technical field [0001] The invention belongs to the technical field of thermal power generation, in particular to a real-time switching device and a switching method for coal types during coal supply during thermal power generation. Background technique [0002] The supply of electricity commodities in the electricity market is characterized by strong real-time performance, especially with the development of the power spot market, more attention is paid to its real-time performance. How to respond to external real-time load changes while reducing power generation costs is a new issue that power plants must face. The current hardware and technology are relatively difficult to solve this problem. [0003] Generating more peak power and reducing load-limited assessments are also important profit growth points for thermal power plants. With the continuous upgrading and improvement of thermal system energy-saving technology. There is less and less energy-saving space for deep t...
