Pulsing Combustion Technology for Firing Solid Fuels

Pulsing combustion technology makes use of the intensifying effect of pulsating gas flow on mass and energy transfer between gas and solids as well as among gases. It has the advantage of high combustion efficiency, intensive heat transfer and low pollutant emission. Starting with a discussion concerning the concept of pulsing combustion, its particular features and application, test results obtained with Rijke type pulsing burners are being analyzed in respect to particularities of combustion, heat transfer and formation of reaction products in the case of combusting solid fuels. Pulsation obviously intensifies heat and mass transfer between the gas flow and the solid particles and is therefore distinguished by high combustion efficiency, good heat transfer property and low pollutant emission. In the conclusion pulsing fluidized bed combustion technology is proposed which combines pulsing combustion with fluidized bed technology. Figs 11, tables 2 and refs 35.
