Parts for boiler furnaces, namely, hoppers, furnace bottoms, furnace walls, ash gates, sluiceways, quenchers, and bunkers

Abrégé

A remote submerged chain conveyor system for separating particles from a coal ash/water slurry from one or more remotely located boiler units. A tank forms an ash holding section, a dewatering section, and an ash settling section. The ash holding section receiving the slurry with first and second opposite ends. The dewatering section dewaters the slurry. The settling zone is an elongated trough connected with the ash holding section at one end with a discharge drain trough at near an opposite end. The tank sections being oriented in a generally linear arrangement wherein a net flow of water from the ash/water slurry is in a direction from the settling zone toward the distal and. A drag chain moves along the ash settling conveying the particles settling from the slurry to the dewatering section.

A drag chain moves along the ash settling conveying the particles settling from the slurry to the dewatering section opposite to a net flow of water. A flocculant supply line upstream of the ash settling section configured for adding a flocculant promoting an agglomeration of particles into flocs. The flocculant supply line is located in a mixing section with an agitator.

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.
