Power & Energy

Most fossil and nuclear fuel power plants rely on the production of pressurized steam to drive turbines and generators to produce electricity. Rupture disks from ZOOK ensure that the systems maintain safe operating pressure levels in boilers and connected steam and condensate piping.

Cooling towers are large scale heat exchangers used to cool and condense steam after it passes through a turbine as it returns back to the boiler. Installation of ZOOK rupture disks ensure that the system does not exceed preset pressure limits.

A safety relief valve automatically releases pressure from a boiler, pressure vessel or other pressure system when the pressure exceeds pre-set limits. A rupture disk is an excellent solution for isolating the pressure relief valve from power plants when the process fluid is highly corrosive to the safety relief valves internal components (trim). By installing a rupture disk fabricated from special alloy rather than the valve trim will dramatically reduce the cost of the safety relief valve. In addition, using a rupture disk in combination with a safety relief valve provides zero process leakage, the release of fugitive emissions and allows in-situ testing of the safety relief valve and extends the working life of the safety relief valve.

Storage tanks containing liquid petroleum, biofuels, natural gas & propane, as well as coal bins containing combustible dust, require safety pressure relief. Rupture disks and vent panels provide instantaneous relief of excess pressure within the storage tank and connected piping.

Liquid fuel pumps, chemical feed pumps for conditioning fuel & boiler water, as well as pumps used for moving cooling water, rely on pressure relief devices to protect against over pressurization on the discharge side of the pump. Rupture disks by ZOOK provide relief from backpressure reducing the chances of permanent damage to the pump, valves and process instrumentation.
