Operational control method of circulating water heat supply unit

Abstract

The invention relates to an operational control method of a circulating water heat supply unit. The method includes: monitoring parameter variation and controlling the unit; monitoring parameter variation of a lower-pressure cylinder part of a turbine by comparing the parameters under high-back-pressure heat supply with those under pure condensation; controlling heat supply network parameters, controlling a pneumatic circulating water pump, controlling low-pressure differential expansion, and controlling middle-pressure steam discharge parameters. By the reasonable steps of the method, operational control of the high-back-pressure circulating water heat supply unit is achieved to solve the problems that related methods are complex in operation and high in implementation cost and overcome the defects of high investment cost, low energy-saving and economical benefits, poor field technical modification adaptability and poor safety reliability, and the requirements of actual conditions can be satisfied.

Description

technical field [0001] The invention belongs to the technical field of circulating water heating unit control, and relates to an operation control operation method of a circulating water heating unit, in particular to an operation control operation method capable of realizing large area, large flow and high back pressure circulating water heating unit . Background technique [0002] At present, my country's economy is growing rapidly, resources are fully developed, and various constructions have made great achievements, but at the same time, they have paid a huge price for resources and the environment. As the contradiction between economic development and resources and environment becomes more and more acute, the phenomenon of air pollution and resource shortage is also becoming more and more prominent, and has become the most serious topic nowadays. This situation is directly related to the irrational economic structure and the extensive growth mode. The "Twelfth Five-Ye...
