Description

Technical Field

[0001] This invention belongs to the field of thermal power plant equipment regulation technology, specifically relating to a method, device, equipment, and medium for regulating the temperature of the steam drum compartment in a thermal power plant boiler. Background Technology

[0002] The steam drum of a thermal power plant boiler is one of the main components of the boiler. It serves as the connecting hub for the three processes of heating, evaporation, and superheating in the boiler's steam-water system, ensuring normal water circulation. Internally, it contains a steam-water separator and a continuous blowdown system to guarantee the quality of boiler steam. With a certain volume, it has a certain heat storage capacity, which can slow down the rate of change in steam pressure when boiler operating conditions change, thus benefiting operation regulation and improving boiler safety. The steam drum is equipped with pressure gauges, water level gauges, emergency drain valves, safety valves, and other equipment and accessories to ensure safe boiler operation. Thermal power plant boiler steam drums are generally equipped with local water level gauges, remote water level gauges, and full-water level gauges. The local water level gauge uses a blind-spot-free bicolor water level gauge, which is safe, reliable, easy to observe, and provides accurate indication. There are seven pairs of water level measuring holes in the steam drum. The remote water level gauge is equipped with a primary valve and a balancing vessel. The balancing vessel is a single-chamber type and matched with electrical compensation methods. The measuring point position accurately reflects the actual weight water level inside the steam drum, with an error of no more than 10mm, preventing false readings caused by factors such as steam flow and water flow. The normal water level in the steam drum, the maximum and minimum permissible water levels, and the installation of an electrical contact water level gauge for indication and alarm purposes, along with a balance vessel for protection, are crucial for the safe operation of high-pressure boilers. Excessive water level, exceeding the required value, reduces the free space in the boiler drum and submerges the cyclone separator, degrading its separation performance. Conversely, the boiler drum must maintain sufficient water capacity to accommodate sudden load changes; the water level must not be too low to prevent insufficient water supply or even boiler burnout.

[0003] The remote water level gauge in the boiler drum is crucial for automatic boiler water level regulation and protection. The accuracy of the boiler water level is fundamental to the safe operation of the boiler. The boiler drum chambers are often constructed to low standards and are relatively rudimentary, requiring temporary insulation in winter and temporary cooling in summer to maintain the necessary working environment for the remote water level gauges and other equipment. The chambers are located at both ends of the boiler drum. Due to their high altitude and significant weather variations, there is a temperature difference between the two chambers under normal circumstances. This large temperature difference frequently causes inaccurate data from the remote water level gauges, significantly impacting automatic boiler water level regulation and potentially leading to malfunctioning protection systems, posing a major risk to the safe operation of the boiler. Summary of the Invention

[0004] The purpose of this invention is to provide a method, device, equipment, and medium for temperature regulation of the steam drum compartment in a thermal power plant boiler. This addresses the problem that in the current technology, the steam drum compartment in a thermal power plant boiler lacks the necessary working environment with equipment such as remote water level gauges, and is not equipped with ventilation and temperature regulation devices. This results in large temperature deviations between the two ends of the steam drum compartment, often causing inaccurate data from the remote water level gauges. This significantly impacts the automatic regulation and protection of the boiler water level, especially under special weather conditions, posing a major risk to the safe operation of the boiler.
