In the production and operation of the power industry, all kinds of equipment and systems are facing safety risks such as abnormal pressure, medium corrosion, over temperature and overpressure. As an important overpressure protection device, safety bursting disc plays a safety guarantee role in many aspects of power production.
In the field of thermal power generation, safety bursting disc can be applied to boilers, steam turbine auxiliary systems, and flue gas treatment. As the core equipment of thermal power generation, the boiler may cause a sudden increase in pressure due to abnormal water quality, clogged pipelines, and failed safety valves during the operation of the soda system. On the outlet pipes of boiler superheaters, reheaters, economizers and other components, safety bursting discs are usually installed in parallel with safety valves. When the pressure exceeds the set value, the safety bursting disc can quickly rupture and relieve pressure within milliseconds to prevent the boiler from exploding due to overpressure. Especially in the environment of high temperature and high pressure, the safety bursting disc can withstand high temperature and can adapt to the complex working conditions of the boiler steam system.
In the field of hydroelectric power generation, safety bursting disc is mainly used in the safety protection of turbines and auxiliary systems of turbines. When the pressure steel pipe of the turbine is turned on, shut down, or the load suddenly changes, it may produce instantaneous overpressure due to the water hammer effect. If the pressure is not relieved in time, it will cause the steel pipe to deform, the welds to crack or even burst. Installing a safety bursting disc at a key location of the pressure steel pipe can break at the moment of overpressure, release the high-pressure water body in the pipe, and relieve the impact of the water hammer.
As an important part of clean energy, nuclear power generation has stricter requirements for safety protection. Safety bursting disc has important protection responsibilities in multiple systems of nuclear power plants. In the first-circuit system of a nuclear reactor, the safety bursting disc is used to prevent system overpressure when the voltage regulator, steam generator and other equipment are operating in an environment of high temperature, high pressure and strong radiation. Due to the strong radioactivity of the nuclear reactor medium, the safety bursting disc needs to be made of special materials to ensure that it will not produce debris pollution after rupture, and at the same time has good radiation tolerance.
In the field of new energy power generation, safety bursting disc is also widely used. The boiler system of biomass power generation is similar to that of thermal power generation, and it needs to be protected from pressure fluctuations caused by fuel combustion through safety bursting disc. In waste incineration power generation, the complex medium environment and pressure changes in the incinerator require the use of safety bursting disc to achieve rapid overpressure discharge and prevent leakage of toxic and harmful gases.
In short, the application of safety bursting disc in the power industry covers many fields such as thermal power, hydraulic power, nuclear energy and new energy power generation. It also involves many equipment and systems, and relies on reliable overpressure protection capabilities. It provides an important guarantee for the safe and stable operation of power production and is an important part of the safety system of the power industry.
