The Ceredo Electric Generating Station in West Virginia uses a Heatec thermal fluid system to heat natural gas from 50 to 115 degrees F. Natural gas fuels the turbine engines that produce electricity.
Heating the gas prevents ice formation when its pressure is reduced for the engines. Ice causes numerous problems such as clogging fuel lines and freezing control valves. Even small ice particles in the fuel can cause extensive damage to turbine engines.
The Heatec system consists of an 11.7 million Btu/hour HCI thermal fluid heater, a heat exchanger, an expansion tank, a pump system and a control panel. The thermal fluid is a non-flammable mixture of water and ethylene glycol. It is heated to 300 degrees F and passes through the heat exchanger where the natural gas is heated.
