A safety valve is a valve that acts as a fail-safe in a thermal-hydraulics plant. An example of safety valve is a pressure relief valve (PRV), which automatically releases a substance from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds preset limits. Pilot-operated relief valves are a specialized type of pressure safety valve.
Gasifier system is one of the important components of coal gasification device. The technical characteristics of this system mainly lie in the following facts as huge technical scale and high complexity, and there is a dynamic correlation between the failure modes of gasification equipment. Traditional safety analysis methods such as fault tree and bow-tie diagram suffer …

Reducing the cost of fuel is a common strategy employed within the industry; in turn, this has led to an increase in the substitution of coal with petcoke. Petcoke and its impact on the coal mill dust collector . One area that has been impacted by the use of petcoke is the coal mill dust collector.
Boiler Safety. Workers that use, maintain, and service boilers know that they can be potentially dangerous. Boilers are gas-fired or electric closed vessels that heat water or other liquid to generate steam. The steam is superheated under pressure and used for power, heating or other industrial purposes.
Coal, lignite or petcoke are ground in the Pfeiffer vertical mill by using hot gases from a hot gas generator. The grinding plant can be inerted. The raw coal is dried while being ground in the mill even if feed moisture exceeds 25%. The feed size that can be handled is up to 100 mm, making two-step pre-crushing unnecessary.
Configuration of the Coal Mills of each boiler unit is with side of the boiler with ten (10) Nos. mills. Each mill is provided with collection and transportation equipment comprising of one no. Pyrite Hopper with water spray arrangement, plate valves at inlet & outlet and a denseveyor or similar pneumatic bulk conveying equipment / vessel.
