Abstract
A coal gasification system has a pulse detonation device. The pulse detonation device is employed to discharge hot exhaust pulses into the coal gasifier. Also, a pulse detonation device discharges reverse flow pulses into a ceramic candle filter system to dislodge particulate build up on the candles. The pulse detonation device utilizes a rotatable core feed cylinder. The core feed cylinder is carried within an inner side wall of the stationary annular detonation chamber. The core feed cylinder has ports in the side wall that will register with ports in the inner side wall of the annular detonation chamber at least once each revolution. Fuel is introduced through valves mounted to the outer side wall of the annular detonation chamber.
