Abstract
An ash transport system and method is provided that includes a transport line, four hoppers, and an airlock or hopper valve attached to each hopper. The ash transport system transports an ash mass from the airlock or hopper valve to the transport line if pressure in the transport line falls below a predefined pressure threshold assigned to the respective airlock or hopper valve. After a predefined period of time elapses, the ash transport system transports the ash mass from the airlock or hopper valve to the transport line if the pressure in the transport line falls below different respective predefined pressure thresholds. The airlocks and hopper valves simultaneously transport the ash masses to the transport line if, prior to the predefined period of time elapsing, the pressure in the transport line falls below each of the respective predefined pressure thresholds.
