Explosion relief consists of taking the effects of the explosion (mainly pressure) through the venting system, outside the device subject to protection. As a result, the pressure inside the device is reduced to a safe level. Three basic types of relief systems are available on the market, i.e. decompression panels, flaps with a self-closing ...
Power generation typically involves direct firing systems. There is an air swept mill with direct pneumatic conveying through to the burners. The risk of explosions is more or less reduced to an explosion inside the mill, which therefore needs to be explosion, pressure, and shock-resistant. NFPA requires coal mills to be good for 50 PSI.

Abstract. The key objective of this paper is the presentation of a new risk assessment tool for underground coal mines based on a simplified semi-quantitative estimation and assessment method. In order to determine the risk of explosion of any work process or activity in underground coal mines it is necessary to assess the risk.
Power generation typically involves direct firing systems. There is an air swept mill with direct pneumatic conveying through to the burners. The risk of explosions is more or less reduced to an explosion inside the mill, which therefore needs to be explosion, pressure, and shock-resistant. NFPA requires coal mills to be good for 50 PSI.
