Application: Steam boiler fuel oil supply filtration required for the standby system, which is necessary to be switched into service at short notice in case the regular heating source, which is gas, has a problem. The system is classified a critical application as the boilers provide steam to the main production plant and to the power generating turbines in the powerhouse.
Problem: Poor housekeeping and system design which allowed the pressure and temperature to exceed above expectations resulting in the fuel oil overheating.
Solution: Airpel duals strainers, model OWO’s with 100% shut off were fitted on the suction and out put sides of the pump. Viton seals were fitted to combat the operating temperature of 150C. Two size of duals are used, a 2” on the suction side and 1 ½ on the out put. The operating pressure is 18 bar G.
