Gas-Turbine Once Through Steam Generator | Canada’s O

Steam generation is a central part of the bitumen production process at steam assisted gravity drainage (SAGD) facilities. Most SAGD facilities have Once Through Steam Generators (OTSG) which burn natural gas to boil water, producing steam that is injected into the ground to soften bitumen.

What Are Once Through Steam Generators - CR4 Discussion Thre

Aug 06, 2014· The Smith steam generator was a once-through type, comprised of water going into about 300 feet of spiraled, pancaked layered, 3/8" copper tubing (used for preheating) and about 50 feet of "used for superheating" seamless stainless steel 1/2" tubing at the outlet. The generator was built for producing 1000 degree F at 1000 psi superheated steam.

Review of Once-Through Steam Generators - OnePet

The once-through steam generator was specifically developed for thermal recovery applications and features a single pass of water through the generator coil and no separating drum. The units are generally designed to produce approximately 80 per cent quality steam, so that the weight ratio of water to steam at the outlet of the generator is

The tertiary cooling water may be recirculated to cooling towers where it sheds waste heat before returning to condense more steam. Once-through tertiary cooling may otherwise be provided by a river, lake, or ocean.
