Our core and related businesses are focused on supplying:
- Once Through Steam Generators (OTSGs) to capture and utilize steam for the Power Generation industry
- High quality steam for Enhanced Oil Recovery (EOR) and SAGD operations
- Boiler repair components – operating as IST Boiler Components
- Organic waste heat recovery solutions – operating as Found Energy
As we move forward, at the core of everything we do, from products to processes and relationships with employees and customers, is our relentless drive to… find a better way.
- IST’s core technology of Once Through Heat Recovery Steam Generators (OTSGs) was developed by a researcher from Solar Turbines in the late 80s named Tom Duffy.
- Tom believed that there was a better way to make steam than using conventional boiler technology which was largely unchanged for 100 years. This provided the start for IST.
- In 1992, two Ontario entrepreneurs, Nichols and Radtke entered into a deal to acquire the technology.
- IST’s current president, Bob Dautovich was hired as engineering manager to transfer technology and start building a team. Key members of the current management team joined shortly after.
- In 2000, IST established a European sales office and booked its first European order.
- In 2009, IST expanded its product line to include Enhanced Oil Recovery (EOR) OTSGs and filed for a patent on an improvement to existing technology to produce 90% quality steam (SQ90™).
- In 2010, IST starts a new company, Found Energy, that will operate in the renewable energy sector whose mandate is to produce electricity from waste heat.
- In 2010, IST signed a fabrication partnership agreement with United Engineering Services in Oman to support the EOR business in the Middle East.
- In 2011, IST designs and manufacturers their 1st EOR 25 MMBtu trailer units and the 70th LM6000 application is completed.
- To date (2012), IST has sold over 190 units in 19 countries around the world.
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 company Solar Turbines made significant progress in refining the OTSG concept for both ship-board and land based use.
The formation of Innovative Steam Technologies (IST) coincided with IST’s acquisition of OTSG technology from Solar Turbines in 1992. IST put the technology to work in Heat Recovery Steam Generator (HRSG) applications operating off gas turbines.
Simply described, an OTSG consists of:
- an enclosed structure with an inlet at the bottom end that accepts heated air (usually exhausted at high velocity from a gas turbine) and an outlet at the top of the structure that allows the air to escape;
- inside this enclosed structure is an uninterrupted bank of high quality steel tubes. Feedwater is fed into the top of the tube bank and is heated by the turbine’s exhaust gas to create steam at the outlet end of the tube bank.
