A COMBUSTION CHAMBER FOR BURNING SOLID FUELS

摘要

A combustion chamber (10) for burning solid fuels having a high volatiles content has a hollow body (11) with a cylindrical wall section (12) and a t op section (13) located at end (14) of the cylindrical wall section (12). Th e hollow body (11) has a primary air inlet (20), a fuel inlet (23) and four volatiles outlets (25) (one shown), mounted therein. Each volatiles outlet ( 25) has a plurality of apertures (26) of differing sizes arranged in a plate (27). In use, the burning volatiles exit the apertures (26) in a turbulent flow resulting in efficient combustion of the volatiles. Additionally, a hea t transferring surface (33) on a water jacket (32) is shaped around the comb ustion chamber (10) so as to define a channel (34) therebetween. This arrang ement results in an efficient transfer of heat from the turbulent flow of vo latiles, which is forced to circulate around the channel (34).
