Further Development of the Precarbon Process
The further development of the Precarbon process is de-signed to achieve rationalisation in operation and reduction of capital expenditure and running costs.
- A twin-stage flash drier, which, in a single column, dries the coal and preheats it to approx. 200°C.
- A single-stage flash drier with intermediate separation and dual product acceleration, which similarly heats the coal to approx. 200°C.
- A chain conveyor permanently connected to the chamber ovens of a coke battery.
Three different locking mechanisms were tested for the new charging conveyor. The tapered connection proved particularly suitable. For purposes of demonstration, a charging conveyor was connected up to four operating ovens. The shut- off devices in the transfer chutes are of the modified tapered connection type; they were subjected to continuous testing and emerged as the best.
