Post purge trip in purging of boiler
A post-purge trip can occur during the purging of a boiler when the system detects that the post-purge cycle has not completed successfully. The purpose of the post-purge cycle is to remove any remaining combustible gases from the furnace and flue gas system after the purging process is complete, inRead More
Loss of fuel protection in FSSS
The Furnace Safeguard Supervision System (FSSS) is an important safety feature in a boiler that is designed to protect against fuel-related hazards, such as fuel leaks or over-pressurization of the fuel system. The FSSS is typically composed of various interlocks, switches, and other safety devices that work together to shutRead More
Boiler flame failure protection
Flame failure protection is an important safety feature in a boiler that is designed to detect if the flame in the burner goes out and take corrective action to prevent any dangerous situations. When the flame in the burner of a boiler goes out, the fuel supply to the burnerRead More
Silica in boiler water (boiler drum)
Silica is a common impurity that can be found in boiler feedwater, and if it is not properly removed or controlled, it can cause various issues in the boiler drum. When water is heated in a boiler, it evaporates and leaves behind any impurities, such as silica, which can thenRead More
Over Fired Air
Overfire air (OFA) is a technique used in utility boilers to reduce emissions of nitrogen oxides (NOx) by injecting additional air above the primary burner zone in the furnace. The additional air helps to lower the peak flame temperature and create a more uniform temperature profile, which reduces the formationRead More
