Plant Utility Heating
A variety of heating options are available for plant Utility Heating.
There are certain factors that must be weighed when selecting plant utility heating equipment. Heating systems can be divided into two categories: direct and indirect. In the case of direct fired systems, the medium which is to be heated comes into direct contact with an electric heating element or the products of combustion. Indirect heating systems utilize a heating medium that is used to distribute heat to desired locations.
Direct fired heating systems are cost-effective, able to achieve high process temperatures and are often ideal for dedicated applications. For applications in which heat is desired in multiple areas, such as pre-heating of combustion gas and process reboilers, indirect heating is typically the preferred choice.
Indirect Steam Heating
Heat from indirect heating systems may be supplied via steam, oil, or a water/glycol mixture. Steam has the advantages of being a very inexpensive and an efficient heat transfer medium capable of achieving high temperatures at superheated conditions. Oil and water/glycol mixtures are capable of operating at temperatures up to 800°F and eliminate the need for costly high-pressure rated systems. Once again, the optimal choice independent on a number of factors and can be evaluated based on the specific application.
