Straw firing demonstration trials: axial swirl burner and fluidised bed combustion

Abstract

This report presents the results of a series of demonstration trials firing straw both in baled and chopped form. The methods of firing under investigation are suspension firing through a conventional pf burner (chopped straw only) and fluidised bed firing of both baled and chopped straw. The two methods of fluidised bed technology under investigations are (a) solid circulating fluidised bed and (b) hot gas generator. Only limited success was achieved firing straw through a pf burner. This was due to the maximum straw feeder output of one tonne/hour being equivalent to the minimum operating load of the pf burner. Oil support was required to maintain an ignition source. It is concluded that better results should be obtained with a higher feed rate of straw and a burner design specifically for straw firing. (Author).
