Boiler (power generation) - Wikipedia

Conditions have to be just right for an explosion to occur and when a boiler is properly operated, it is not possible for such an event to take place. The most common causes of a fuel explosion are: Fuel-rich mixtures - The danger of a fuel-rich mixture is that high concentrations of unburned fuel can build up.

The Effects of Corrosion in a Boiler | Chardon Labs

Boiler corrosion causes half of all forced outages and almost all tube failures of boilers in power plants, making it crucial to prevent. However, power generation plants are far from the only ones affected by corrosion and failure of boilers. Any facility that uses steam boilers can experience disruptions from corrosion damage.

Optimization of Boiler Operation In Thermal Power Station

The superheated steam produced in boiler is supplied into a steam turbine where its thermal energy is Converted into mechanical work on the turbine shaft. In this case all the steam after partialexpansion in the turbine (HPT) is brought back to the boiler, r-heated by flue gases and then fed back to the turbine for further expansion at IPT & LPT The turbine is connected to an electric generator in which the …
