Week 5, 5th May

The plant has the force outage as the HP feedwater NRV is not functioning. The valve needs to be open to let the HP feedwater flow from boiler feedwater pump but the valve is jammed. Hence, the mechanical technician use hydraulic jet to force the valve open and repair will be done during the outage.

In the evening, I followed abang Syahrul to do the HRSG1 Siemens Continuous emission monitoring system (CEMS) inspection. We need to check the lamp, switch, indication bulbs whether it is function or not. Then, we need to take the measurement for UTM120 and UTM130 device for the flow rate and percentage of oxygen.

Abang Syahrul explained the CEMS to us on how it works
