Method of Improving Uniformity of Circulating Water Flow Between Heater Network Heaters

Abstract

The invention relates to a method for improving evenness of circulation water flow among heaters of a heating network. The method comprises the steps that (1) whether the problem that circulation water flow is uneven in distribution exists among the heaters of the heating network or not is judged; (2) when the flow is even, the state is maintained, when the flow is uneven, the valve opening of the inlet and outlet of the heater, with low circulation water flow, of the heating network is adjusted to 100 percent; (3) if the flow is even after regulation, the state is maintained, and if the flow is uneven after regulation, valves are overhauled manually on site; (4) if the flow is even after overhauling, the state is maintained, and if the flow is uneven after overhauling, regulation is carried out according to the operation mode of the heaters of the heating network of a heating network system of the corresponding period; (5) if the circulation water flow is even in distribution, the operation state of the current heating network system is maintained. The method improves the evenness of the circulation water flow of the heaters of the heating network and optimizes the operation mode of the heaters of the heating network, and the purposes of energy conservation and consumption reduction are achieved.

Description

technical field [0001] The invention belongs to the technical field of thermal power generation and energy saving, in particular to a method for improving the flow uniformity of circulating water between heating network heaters. Background technique [0002] The heat network heater is the key equipment of the heat network system and one of the main equipment of the thermal power plant. Its main function is to use the steam extracted from the steam turbine or the steam (heating medium) drawn from the boiler to heat the circulating water in the hot water supply system To meet the requirements of heating users, so as to realize cogeneration of heat and power. When the circulating water flow in different heating network heaters of the heating network system in the same period has a large deviation (flow deviation ≥ 30%), the circulating water flow of the system is unbalanced, and the hydraulic imbalance of the system causes poor heating effect of the system, which not only affec...

Problems solved by technology

When the circulating water flow in different heating network heaters of the heating network system in the same period has a large deviation (flow deviation ≥ 30%), the circulating water flow of the system is unbalanced, and the hydraulic imbalance of the system causes poor heating effect of the system, which not only affects the entire system The normal operation and heating effect of the system also caused a huge waste of energy

There are many factors that affect the uneven flow of circulating water in the heating network heating system, but there is no solution to the uneven flow of circulating water caused by various factors, resulting in the loss of energy
