CASE STUDY

Coal Fired Power Station Case Study

Rapp-it can be used on air heater, water, slurry, hot ash and chute pipe-works found widely throughout coal fired power stations, where temperatures can range from 0°C to 140°C.

Scope

The customer advised the coal discharge chute had a leak. This would normally require a replacement; however, the power station was unable to stop coal handling processes.

Solution

The customer used Rapp-it Steel Putty and applied several Rapp-it Pipe Repair Bandages (100mm x 4.8m) to fix the damaged chute. This allowed the customer to continue preparing coal for export until a maintenance shutdown could be scheduled.
