Kinetrol actuator on
descale water system. |
Overtime, heat exchanger tubes in power plant boilers build up mineral deposits that prevent proper heat transfer. The poorer the heat transfer, the higher the boiler tube exposure temperature. The higher the exposure temperature, the shorter the life of the boiler tubes. To remedy this, a chemical and mechanical process called descaling is used. Descaling removes these mineral deposits and restores proper heat transfer.

This
Kinetrol actuator application is located on the descale water system at a power plant in the Midwestern United States. Knifegate valves with pneumatic cylinder actuators were installed on the system and were failing. The knifegate valve packing material leaked and created a maintenance nightmare. The customer needed a longer term, lower maintenance solution.
The local Kinetrol Distributor recommended switching to a high performance butterfly valve (HPBV) and
Kinetrol double acting actuator as the replacement. These actuators and valves are installed in a very dirty area (see picture), and during power generation, are exposed to high heat and are cycled every 30 seconds. The first installation has been in place for 20 months and operating without problem. Now, as each knifegate comes up for maintenance, they are being replaced with the Kinetrol operated butterfly valve.
