Torrefaction. Prabir Basu, in Biomass Gasification, Pyrolysis and Torrefaction (Third Edition), 2018. Explosion Potential of Torrefied Dust. Dust explosion is a major problem in handling and conveying fine dusts especially of easily ignitable materials. Torrefaction makes biomass brittle and could result in more dust during handling. Additionally, due to its high reactivity and low ...

A problem often is that silos supplied for the storage of alternative fuels come from companies with an agricultural background. The designs then often are incorrect in aspects like explosion pressure shock resistance and explosion venting, e. g. when nonselfreclosing explosion vents are installed, which makes effective firefighting impossible.

Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill startup, stopping coal feed on shutdown, or when equip ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust will

Differential pressure (dP), as the name suggests, is the difference in the pressure measurements between two points in a system. In baghouse systems, that measurement is the difference in the air pressure from one side of the filter media to the other. Whenever air moves through those filters, it creates resistance between the dirty side of a ...
