Steam Turbines for Critical Applications and Emergency or Standby Drives
(Energy Systems Laboratory (http://esl.tamu.edu), 1986-06)
Steam turbines are frequently preferred over electric motors where operational continuity is important. This often imposes extreme premiums in operating cost. The parameters affecting relative economics are explored and a ...
Separation Process Economics
(Energy Systems Laboratory (http://esl.tamu.edu), 1985-05)
Heist Engineering is comparing the
economics of separations processes as
part of current programs with the US
Department of Energy, the Electric power
Research Institute, and industrial
clients. The initial results ...
Absorption Heat Pumping- Have You Tried It?
(Energy Systems Laboratory (http://esl.tamu.edu), 1985-05)
The concept of a thermal powered absorption heat pump is not a new or revolutionary idea. It has been successfully demonstrated in the lab and prototypes have been installed in the field. Units have been successfully applied ...
Small-Scale Industrial Cogeneration: Design Using Reciprocating Engines and Absorption Chillers
(Energy Systems Laboratory (http://esl.tamu.edu), 1985-05)
This paper describes a packaged cogeneration system
designed for light industrial applications (i.e.,
situations where a user wants a maximum of 1 MW of
cogenerated electricity). The design employs reciprocating
engines ...
Hybrid Heat Pump Design and Application
(Energy Systems Laboratory (http://esl.tamu.edu), 1985-05)
The Hybrid Heat Pump (HHP) converts industrial waste heat into process steam. Waste heat at temperatures as low as approximately 200°F can be used. Steam output covers a range between 12,000 Ib/h and 50,000 Ib/h, depending ...
Design and Economic Evaluation of Thermionic Cogeneration in a Chlorine-Caustic Plant
(Energy Systems Laboratory (http://esl.tamu.edu), 1985-05)
The study shows that it is feasible to equip a chlorine-caustic plant with thermionic cogeneration. Thermionic combustors replace the existing burners of the boilers used to raise steam for the evaporators, and are capable ...
Why Energy Projects Do Not Get Approved
(Energy Systems Laboratory (http://esl.tamu.edu), 1986-06)
We have all struggled to convince management to
pursue energy conservation alternatives using
economic arguments such as internal rates of
return, project payback, and net present value.
Some have tried life cycle ...
Industrial Heat Pumps--Types and Costs
(Energy Systems Laboratory (http://esl.tamu.edu), 1985-05)
Many potentially beneficial applications for industrial heat pumps are not being pursued because of confusion regarding both energy savings and economics. Part of this confusion stems from the variety of heat pumps available ...
Variable Flow Chilled Water Systems
(Energy Systems Laboratory (http://esl.tamu.edu), 1985-05)
Today, substantial savings can be achieved by converting constant flow-rate chilled water systems to variable flow-rate systems. This conversion is best suited for large, central plant chilled water systems where two or ...
Economic and Technical Tradeoffs Between Open and Closed Cycle Vapor Compression Evaporators
(Energy Systems Laboratory (http://esl.tamu.edu), 1986-06)
Evaporators are used extensively in the chemical,
pulp and paper, food and beverage, and related
industries. Mechanical vapor recompression (MVR)
evaporators are a type using an open heat pump
cycle with steam as the ...
