Abstract
This chapter discusses the development of a high-intensity combustor for liquid fuels. To achieve a high-intensity combustor for liquid fuels, the equipment used for the experiments consisted of a rotary cup burner in combination with a refractory-lined combustion chamber. The air passing through the air nozzle had both an axial and a tangential velocity. The interesting observation made was that combustion in the chamber may, depending on conditions, proceed with either of two flames of completely different shape and type. The features of the new combustor are: (1) smokeless combustion of liquid fuels ranging from gas oil to asphalt at or nearly at stoichiometric fuel-air ratios is possible. No coke deposition occurs. (2) The flame is practically non-luminous, a desirable feature for process furnaces. (3) Lifetime of the refractory lining of the combustion chamber is fully satisfactory for the regular commercial fuels; for high ash fuels, such as certain asphalts burnt from time to time in refineries, refractory lifetime is rather short. (4) The air pressure required is rather high. This fact partly offsets the benefits of more economical combustion. (5) The front space of a furnace or boiler required for the combustor is considerable. For high-load furnaces or boilers this has led to difficulties in accommodating a sufficient number of combustors.
