The combustion chamber is of a V profile double vertical grille. Under this are two blower openings (15) with separate outlets. The space between the openings is closed at the base (19) to assist air flow upwards. The closure is a flap, which can be opened to remove ash. The grille has central supports (9) which are hollow for drawing external air to the top of the combustion chamber. There are also grille cross pieces (10) with movable rods (12) on them. At the top (30), a feed re-cycles, to the blower, some of the oxygen rich combustion gases. |
