Abstract

The invention discloses a coal-water slurry boiler steam supply engineering system provided with the self-adapting three-control function, which comprises a monitoring system, a procedure control system and a field control system, wherein the monitoring system comprises an attendant manufacturing process supervisory control computer; the procedure control system comprises a high-pressure analog quantity control subsystem, a low-pressure analog quantity control subsystem, a heat accumulator control system, a boiler hearth safety surveillance system, a feed pump control system and a switching value control function block all connected with the attendant manufacturing process supervisory control computer respectively; and the field control system comprises a high-pressure coal-water slurry boiler, a low-pressure coal-water slurry boiler, a steam heat accumulator, a water pump and an auxiliary equipment system connected with the coal-water slurry boiler steam supply engineering system. The system provided by the invention solves the difficult problem of complicated multi-quality condition and requirement of high-fluctuation steam utilization of the conventional coal-water slurry boiler, obtains higher economic benefits, and is precedent in the high automation of coal-water slurry boilers.

Description

technical field [0001] The invention relates to the technology of coal-water slurry, in particular to the improvement technology of the control system of the steam supply project of the coal-water slurry boiler. Background technique [0002] The current overview of coal water slurry technology is as follows: [0003] 1. After 30 years of continuous efforts of several generations of scientific and technological workers in my country's coal water slurry technology, its application technology has matured and is at the forefront of the world. Especially since the recent surge in international oil prices, CWS technology has achieved fruitful results. In 2010, Zhejiang University’s “Industrialization of Coal-Water Slurry Combustion Technology” won the second prize of National Science and Technology Progress Award. [0004] However, because CWS is a liquid mixture of coal and water, its particle size, viscosity, concentration, and stability are quite different. Therefore, the com...
