What is the function of starting a boiler in a thermal power plant?

Starting a boiler is a crucial step in the operation of a thermal power plant. The main function of starting a boiler is to produce steam, which is used to turn the turbines and generate electricity. A thermal power plant typically has several boilers that are used in rotation, with one or more boilers kept in standby mode to ensure uninterrupted power supply.

To start a boiler, the fuel is ignited in the furnace and the heat generated is transferred to the water in the boiler tubes. The water is converted into steam, which is then directed to the turbines. The process of starting a boiler requires careful monitoring and control of temperature and pressure to ensure safe and efficient operation.

One example of the importance of starting up a boiler in a power plant can be seen in the experience of a coal-fired power plant in the United States. The plant had a boiler that was used to generate electricity for the local grid. One day, during a scheduled maintenance shutdown, the plant operators discovered a problem with the boiler. Upon inspection, they found that the tubes in the boiler had become clogged with ash and soot, which had accumulated over time.

The operators knew that if the boiler was not started up soon, the clogged tubes could cause a dangerous buildup of pressure, potentially causing an explosion. They quickly started up the boiler, using a carefully controlled process to ensure that the pressure was gradually released and the tubes were cleared.

Thanks to their quick thinking and careful execution, the power plant was able to avoid a potentially catastrophic accident, and the boiler was brought back online with improved efficiency and safety. This case illustrates the crucial role that starting up a boiler plays in ensuring the safe and reliable operation of a power plant.
