Reliability Maintenance Simplified

Fuel for boiler is provided by clean wood waste from sawmills and lumber and paper mills; natural gas is used for boiler start-up and auxiliary boiler. All major functions in the plant are controlled by operators with computer support to continuously monitor and report on pressures, temperatures, flow rates, etc.

The attemporator controls steam temperature but the issue was the on/off isolation valves for the attemperator control were leaking and cutting trim on the control valves. The original valves, supplied by the boiler manufacturer, were globe-style valves attached to electric actuators. The plant manager could not get adequate service support from any of the original equipment makers. Consequently, there was no consistent control of the steam generated by the boiler operation.

The plant manager is pleased with how the Novaspect solution has made valve maintenance much easier. The technicians who maintain the equipment on-site prefer the double-acting pneumatic actuator to the inferior original electric actuator performance. In addition, the local support of sales and service reps is convenient and helpful for training and troubleshooting.
