Jordan Hospital,
Plymouth, Mass.
Two Waukesha natural
gas-fired reciprocating engines were installed in 1994 at Jordan Hospital,
Plymouth, Mass., to produce both electrical and thermal energy with an
overall plant efficiency of approximately 85%. The electrical energy is
fed into the hospital switchgear and runs in parallel with the grid (importing
approximately 10 kW). The hot water from the engine, at 250°F, is fed
into an exhaust heat recovery boiler that is then flashed into steam and
fed into the hospital's steam header for distribution throughout the hospital.
Excess steam passes through an absorption chiller and is used for hospital
cooling. The cogeneration system can be used as emergency generators in
case of an electrical utility outage, allowing the entire hospital to continue
to run despite any outside utility power failure.
Summary:
-
Cogeneration system has saved the hospital over $350,000
per year.
-
The hospital has two 525 kW units for self generation.
Full-rated power will be 1,050 kW per hour.
-
The system is capable of generating over 8,760,000
kWh per year.
-
Cogen produces 3,500 Ibs. of 15-lb steam per hour.
This thermal is piped into the steam header to be used for heating and
chilling.
-
Cogen also is used for emergency power.
-
System payback is estimated at approximately four
years.
Loctite Corporation,
Rocky Hill, Conn.
The Loctite Corp. decided
to install a cogeneration system in its new research and development center
in Rocky Hill, Conn., to lower operating costs and to achieve higher levels
of control of future utility costs. Other considerations were energy expenditure
savings that could be used in Loctite's business activities and using an
innovative technology that does not harm the environment.
The two Jenbacher cogeneration
units installed are reciprocating engines using natural gas to produce
both electrical and thermal energy. Combined, these units will produce
approximately 1,182 kW per/hr. of electrical energy and approximately 39,074
mmbtu/year thermal energy. Loctite will run in parallel with the utility,
making it a win/win situation for all.
Summary:
-
Capable of generating 9,500,000 kWh/year, which has
saved approximately $460,000 per year in energy cost.
-
Combined thermal and electrical efficiency will be
approximately 88%.
-
Thermal will be used in the form of hot water heating
and chilling of the building.
-
State of the art emission system contributes to a
clean environment .
-
Return of investment estimated at less than four years.
