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.
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.
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 steam is subsequently condensed via cooled water from a tertiary loop and returned to the steam generator to be heated once again. 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.
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.
1. State the function of the once-through steam generator (OTSG). 2. List the three heat transfer regions of the OTSG. 3 DibH & Wh th i t d 2. Describe ow y the areas associated with the 3 heat transfer regions change with an increase or decrease in plant load. 4. Explain why the differential temperature between the tubes & shell of the OTSG is
Once Through Heat Recovery Steam Generators (OTSGs) are the most significant advancement in steam generation in over a century. Until the 1980s, conventional drum boilers were used to produce steam. At about this time, the US Navy investigated the use of combined gas turbine and steam turbine plants for additional ship propulsion power. The US […]
