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 top section (13) located at end (14) of the cylindrical wall section (12). The 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 heat transferring surface (33) on a water jacket (32) is shaped around the combustion chamber (10) so as to define a channel (34) there between. This arrangement results in an efficient transfer of heat from the turbulent flow of volatiles, which is forced to circulate around the channel (34).
A combustion chamber for burning solid fuels having a high volatiles content, the combustion chamber comprising an enclosed hollow body in which the fuel is to be burnt, the body having a fuel inlet, a primary air inlet, a secondary air inlet and a burning volatiles outlet mounted therein, the burning volatiles outlet having a plurality of apertures, such that, in use, the burning volatiles exit the apertures in a turbulent flow resulting in efficient combustion of the volatiles.
A fire chamber for a device for burning solid fuels having a high volatiles content, the fire chamber comprising a housing, a combustion chamber within the housing, the combustion chamber having an enclosed hollow body in which the fuel is to be burnt, the body having a fuel inlet, a primary air inlet, a secondary air inlet and a burning volatiles outlet mounted therein, means associated with the burning volatiles outlet for turbulating the burning volatiles as they exit therefrom, in use, the housing having an inner heat transferring surface shaped about the combustion chamber so as to define a channel therebetween, such that, in use, the burning volatiles exiting the burning volatiles outlet are forced to circulate around the combustion chamber within the channel in a turbulent flow resulting in efficient combustion of the volatiles.
