Abstract

The invention discloses an intelligent boiler shutdown protection process for a thermal power generating unit starting boiler, which is suitable for various thermal power generating units with starting boilers, realizes intelligent boiler shutdown protection for the starting boilers in the shutdown period of the starting boilers, and reduces or avoids daily manual operation. Aiming at the characteristic that the start-up boiler needs long-term anti-corrosion maintenance, the system is arranged near the start-up boiler, and intelligent nitrogen charging anti-corrosion protection of the start-up boiler is realized by arranging a nitrogen making machine, a nitrogen storage tank, an automatic valve, a pressure reducing valve, a nitrogen purity meter, a nitrogen humidity meter, a pressure transmitter, a flow meter and the like. The system is arranged near a starting boiler, nitrogen cylinders do not need to be replaced frequently, and manual monitoring is not needed.

Description

technical field [0001] The invention relates to an intelligent shutdown protection process for starting boilers of thermal power units, which is suitable for various thermal power units with startup boilers, realizes intelligent shutdown protection for startup boilers during shutdown of startup boilers, and reduces or avoids daily manual operations. Background technique [0002] Most thermal power units are equipped with start-up boilers, which are necessary auxiliary equipment when the unit is started. The start-up boilers only run when the unit is started, and are in standby state at other times, requiring long-term anti-corrosion maintenance. There are many ways to start the boiler anti-corrosion maintenance for thermal power units, the most commonly used is the nitrogen protection method. A nitrogen filling port is set near the start-up boiler, and a nitrogen bottle is used to protect the start-up boiler with nitrogen. This method cannot guarantee the nitrogen quality i...
