Compressed air heating - raising temp. of combustible first gas bottle and scrubbing flue gases in following bottles

摘要

A compressed air heating system uses a compressor to heat coal fines or shredded waste tyres to combustion heat in a propane gas bottle. Subsequent gas bottles are filled with gravel, soap suds and oil to remove all dust and soot from the flue gases. This provides heat for greenhouses, workshops or swimming baths at low cost and without dust or soot in the flue gases.
