EOR Once Through Steam Generators and Steam Systems by EN-FAB Inc
EN-FAB Inc provides EOR once through steam generators designed for reliable, high efficiency steam production with flexible pressure options for enhanced oil recovery operations.
The EN-FAB Steam Generator is a "Once Through" forced circulation type. Designed to supply wet, saturated or superheated steam discharge conditions, Once Through Steam Generators are favored for any installation where low life-cycle costs, high reliability, and or high-purity steam is desired. Pressure ratings are supplied to customer's specifications and are normally furnished in 1000, 1500, or 2500 PSIG working pressure.

The radiant section is cylindrical with horizontal tubes transposed around the radiant section for equalized heat pick up. The tubes are supported with high alloy tube supports and are free to expand with temperature changes. The radiant section also provides large furnace volume for flexibility in combustion fuel and firing changes. The heat transfer surface in the radiant section normally picks up about 60% to 65% of the overall heat transfer duty. The refractory lined wall provides for reflective heat transfer to the tubes and insulation to reduce heat loss through the chamber wall.
