Our unique waste heat powered turbine system permits you to use waste-heat from your regenerative,
catalytic or direct fired thermal oxidizer exhaust stack to power the turbine generator. You may use the
equipment on new or retrofitted equipment. This technology was developed to operate on typical exhaust
stack temperature, the exhaust stack temperature supplies a minimum of 125F differential temperature
between the heat source and sink.
Utilizing Low Temperature Waste Heat
Waste heat availability worldwide is very large with 95 percent of waste heat is at or below 100 C (212 F)
range. Our Micro-Turbines are more efficient operating within this range.
The Use of Smaller Micro Turbine Systems
There are a very small number of companies that offer micro turbines, most of the manufacturing is
focused on systems which operate above the 500 kw/hr output. Very few large manufacturers’ focus on
turbine systems above 1 MW/hr output. Much of the world's waste-heat availability may operate 10-250
kw/hr turbine system size. For this reason, we have focused our efforts on systems that are able to use
stack waste as the heat source. Small micro turbine systems capture the lost energy and profit from the low
grade heat exhaust.
Our focus is on capturing this low grade thermal oxidizer heat which would otherwise be vented to the
atmosphere and converting it to generate rotational horsepower, which can be used to power a electrical
generator. In addition, the exiting, heat from the turbine can be used to preheat the incoming process air to
reduce operating costs on the thermal oxidizer.
American Recovery and Investment Act.
This bill would allow taxpayers to receive a grant from the Treasury Department in lieu of tax credits. This
grant will operate like the current-law investment tax credit. The Treasury Department will issue a grant in
an amount equal to thirty percent (30%) of the cost of the renewable energy facility within sixty days of the
facility being placed in service or, if later, within sixty days of receiving an application for such grant.
American Clean Energy and Security Act
This milestone legislation would pay for 50% of the Waste Heat Micro Turbine Equipment based on "... The
value of 25 percent of the energy projected to be recovered or generated during the first 5 years of
operation at the facility...". Click here for more info: American Clean Energy And Security Act
The Turbine Cycle
The working fluid is turned into vapor by the application of a heat source in the evaporator. The fluid vapor
expands in the turbine and is then condensed using an ambient air heat exchanger on the inlet process
flow for cooling. The condensate is pumped back to the evaporator thus closing the thermodynamic cycle.
Heating and cooling sources are not directly in contact with the working fluid or with the turbine.
Micro Turbine Advantages
a. High system effectiveness
b. High turbine efficiency (up to 85 percent)
c. Low mechanical stress of the turbine, suitable to the low peripheral speed
d. Low turbine speed, direct drive generator devoid of reduction gear
e. No erosion of blades, due to the absence of moisture in the vapor nozzles
f. Long life
g. No operator required, PLC Controlled
h. Can be service by standard refrigerant technician
i. May Operate on Existing Thermal Oxidizer PLC platform and controls
The system has practical advantages, such as simple HMI start-stop procedures, low noise operation and
minimum maintenance requirements.
Our Turbine System consists of a single skid-mounted assembly, containing all the equipment required for
the power skid to be operated (i.e. Heat exchanger's, piping, working fluid feed pump, turbine, electric
generator, control and switch-gear). Larger units are composed of multiple modules, pre-assembled at the
factory. All systems are easy to transport and to installed, and they are easy to interface with the hot and
cold sources on site with our thermal oxidizer heat exchanger's.
Example of Energy Provided on 250kw System
Cost Per Kilowatt: $0.072
250 Kw: 250 x $0.072 = $18.00 Per Hour
24 Hr. Cycle: $18.00 x 24 Hrs. = $432.00
360 Days Per Year: $155,520.00
American Clean Energy and Security Act (Award Program)
$155,520.00 x 5 Years = $777,600.00
