Abstract (en)
[origin: WO8808502A1] The fire grate comprises, in its length, two successive gratings (41, 42) having essentially the same general slope and connected to each other essentially directly below the bridge (7), each grating possessing its own mobile frame with its own means of control (45, 46) and its own flue gas caisson (43, 44) with its own means of ventilation. It is thereby possible to regulate the combustion conditions to optimize the carbonization mode on the upstream layer (41) and the burning mode on the downstream layer (42).
