Combustion chamber for burning solid fuels

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 providing primary air of combustion to the combustion chamber, a secondary air inlet providing secondary air of combustion to the combustion chamber, and a burning volatiles outlet mounted therein, and

• wherein a means for turbulating is associated with the burning volatiles outlet such that, in use, the confluence of burning volatiles and secondary air of combustion is turbulated on entering the housing, resulting in efficient turbulated combustion of the volatiles within the housing, 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 turbulated confluence of burning volatiles and secondary air exiting the burning volatiles outlet is forced to circulate around the combustion chamber within the channel in a turbulent flow resulting in efficient combustion of the volatiles,
• wherein two or more burning volatiles outlets are mounted in the hollow body, and
• wherein the burning volatiles outlets are positioned and orientated about the surface of the hollow body so as to induce the burning volatiles to circulate around the hollow body and thereby facilitate the optimisation of the turbulent flow of burning volatiles thereabout for more than one output setting.

• wherein the combustion chamber is positioned at the top of the fire chamber, the burning volatiles outlet is mounted in the upper region of the combustion chamber, and an exhaust gases outlet is mounted in the housing below the combustion chamber, such that, in use, the burning volatiles, as they exit the burning volatiles outlet circulate around the top of the combustion chamber in the channel until they start to cool and consequently drop down in the channel, with the exhaust gases exiting the chamber through the exhaust gases outlet.
