POWER STATIONS IN SOUTH AFRICA
- REDUCED COOL SIDE FOULING RESULTING IN A CLEAN ECONOMISER
- EXTENDED BOILER OPERATING PERIODS
- INCREASED BOILER AVAILABILITY
- NO FALL OF IN OUTPUT DURING OPERATION
- BOILER CLEANED IN 5 DAYS INSTEAD OF USUAL 21 DAYS
The main issue that resulted in early shutdowns was that the economisers fouled up very quickly. Sapec managed to reduce the fouling in the economisers resulting in these dramatic results:
- Extended operating periods from 8 weeks to 21 weeks.
- No fall of in output despite boiler using 22058 tonnes of coal compared to normal operation cycle 8400 tonnes a 262% increase
- Boiler cleaned in 5 days instead of usual 21 days
