Abstract
The invention relates to method and apparatus for the combustion of fluidal fuels. The fuel is dispersed in combustion air and, in order to improve the combustion rate and efficiency, is exposed to a high particle velocity of a sound produced by a low frequency sound generator. The frequency of the sound is determined by the sound generator, the maximum frequency being 30 Hz. A reciprocating movement of combustion air and fuel particles entrained therein is obtained. The sound generator is a quarter wave type sound generator with a tubular resonator forming a diffuser at the open end thereof.
