AN APPARATUS FOR HANDLING POTENTIALLY EXPLOSIVE FINES SUCH AS CLYASH

摘要

Apparatus including an enclosed pressurized conveying and storage system that will allow potentially explosive flyash or other fine material to be handled with the minimum possibility of damage to the equipment in the event of an explosion. The steel storage vessel is maintained under slight pressure with inert gases by means of a pressure relief valve and an inert gas supply, and is kept at a high enough temperature to prevent condensation of the gas (so that corrosive acids are not formed) by electric inductance heaters and insulation. Airlock valves are used to allow the ash into and out of the transport and containment system.
