Dual Pulse-Jet System for the Combustion of High Ash Fuel

Details

• Personal Author:

• Description:
  Coal is burned in vertically oriented, dual opposed pulse-jets. Each jet's combustion chamber upwardly discharges combustion gases through a vertical tailpipe bent at its upper end in the direction of the pipe on the adjacent jet so as to allow combustion gases to propel back and forth between the adjacent tailpipes. Combustion air is drawn upward through a centrally located conduit. Refractory material lines the walls of the jets so as to maintain the average gas temperature above the melting point of fuel ash. Entrained ash in the combustion gases is caught on the walls of the pipes and combustion chamber and drains down the walls as molten slag to the bottom of the jets. [Description provided by NIOSH]
