Coal properties and their effect on combustion in utility boiler
Coal properties play a critical role in the combustion process in utility boilers when fired in pulverized condition. The following are some of the essential coal properties that can affect combustion:
Recuperative Tubular Air Preheater
A tubular air preheater is a type of heat exchanger that is commonly used in thermal power plants to improve the efficiency of the boiler by recovering waste heat from the flue gases. It preheats the combustion air before it enters the boiler, which helps to reduce the energy requiredRead More
Volatile matter in coal
Volatile matter in coal refers to the components of coal that are released as gas or vapor when the coal is heated or burned. Volatile matter is an important factor in determining the properties of coal, as it affects the combustion behavior, heating value, and environmental impact of the coal.Read More
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
