Heat Recovery Steam Generator Pays for Electric Generator and Itself in Less Than 8 Years!

Take a prime power generator, install a Cain Industries HRSG and great things happen...

Let’s start with a new 1000kW generator at a cost of $1,200,000. Now we’re going to place a Cain ESG1 heat recovery steam generator into the exhaust stream at a cost of $169K. With a conservative fuel cost of 65¢ per therm and 8,000 annual operating hours our HRSG is going to produce $182K of steam from recovered heat energy per year for approximately 20 years.

Generator $1.2MM + HRSG $169K รท Recovered Energy $182K = 7.5 Years Payback

Exhaust Heat Exchanger Pays for Generator and Itself in Less Than 6 Years!

Take a prime power generator, install a Cain Industries heat exchanger and great things happen...

Let’s start with a new 1000kW engine or turbine generator. Now we’re going to place a Cain HRSR heat exchanger into the exhaust stream. With a conservative fuel cost of 65¢ per therm and 8,000 annual operating hours our exchanger is going to yield enough recovered heat energy to pay for the generator in less than 6 years.

History Dictates Higher Fuel Prices!

The New York Mercantile Exchange (NYMEX) determines fuel pricing using the Henry Hub pipeline as a benchmark for natural gas and the West Texas Intermediate (WTI) for crude oil. We all know there’s been drastic price fluctuations over the last 20 years.

An investment in Cain Industries exhaust heat recovery equipment back in 1998 would have occurred during a low fuel price period, even lower than today. Still, equipment paybacks averaged less than 24 months. The anticipated life expectancy of Cain equipment is approximately 20 years. Marvel at the incredible yields that initial investment provided during this time frame. It’s important to note that this period also holds the highest fuel prices ever recorded: Natural Gas in 2005 and Crude Oil in 2008.

While we’re enjoying somewhat lower fuel prices today we must not forget the past. History dictates that fuel prices will climb again in the future. It also demonstrates that Cain Industries exhaust heat recovery equipment is a sound investment providing healthy returns under any fuel market condition.

Economizer Pays for Boiler and Itself in Less Than 7 Years!

Take a new or existing steam boiler, install a Cain Industries economizer and great things happen...

Let’s start with a new 500 HP (150 psi design) steam boiler at a cost of $200K. Now we’re going to place a Cain RTR rectangular economizer into the exhaust stack at a cost of $38K. With a conservative fuel cost of 50¢ per therm and 6,000 annual operating hours our economizer is going to yield almost $39K of fuel savings per year for approximately 20 years.

Boiler $200K + Economizer $38K ÷ Fuel Savings $39K = 6.1 Years Payback

Every economizer application is unique and will provide different payback results. Contact Cain Industries today to evaluate your specific exhaust heat recovery requirements and to receive a FREE Savings Analysis Study with Guaranteed Performance!
