February 2008:
Exergetic Systems is Issued US Patent for the
Input/Loss Method Using Genetics of Fossil Fuels
United States Patent No. 7,328,132 was issued February 5, 2008 for "Input/Loss
Method Using the Genetics of Fossil Fuels for Determining Fuel Chemistry,
Calorific Value and Performance of a Fossil-Fired Power Plant".
This parent patent is a foundation disclosure which protects the discovery of
the genetics of fossil fuels applied to the Input/Loss Method in which fuel
chemistry is determined based on effluents.
July 2007:
Exergetic Systems Issued European Patent for
Detection of Tube Leaks
European Patent (GB, IE) No. 1,502,188 was granted July 25, 2007 for "Method for Detecting Heat
Exchanger Tube Failures and Their Location When Using Input/Loss Performance
Monitoring of a Power Plant". This patent is a foundation disclosure which
protects an improved ability to determine the flow rate of a steam generator's
tube leak and identifies which heat exchanger has the failed tube.
July 2007: Lang, Rodgers and Mayer receive ASME's Prime Movers Award The American Society of Mechanical Engineers has awarded Fred Lang of Exergetic Systems, Dave Rodgers and Loren Mayer both of Portland General Electric the Prime Movers Committee Award for their paper: "Detection of Tube Leaks and Their Location Using Input/Loss Methods" (see Technical Papers). This award recognizes outstanding contributions to the literature of thermal electric station practice; it was established in 1954.
June 2007:
Fred Lang to co-author three ASME Papers
Our Company President will be co-authoring 3 papers at the upcoming ASME Power
Conference, July 17-19, 2007 in San Antonio, Texas.
These include: "An Oxy-Hydrocarbon Model of Fossil Fuels"; "What's Wrong with
Thermal Performance Engineering?"; and an Input/Loss Part V. The "What's Wrong"
paper, prepared by six experienced engineers, is a discussion of the current
state-of-affairs in maintaining and improving heat rate. The Part V paper
presents techniques which allow verification of on-line monitoring systems.
May 2007: Exergetic Systems announces
victory in European Patent Office case
ABB Patent GmbH (a subsidiary of ABB Ltd) and STEAG Ketek IT GmbH (a subsidiary
of STEAG encotec Gmbh), both of Germany, opposed Exergetic Systems’ European
Patent (GB, GR, IT, DE) 1171834, “Input/Loss Method for Determining Fuel Flow,
Chemistry, Heating Value and Performance of a Fossil-Fired System”. In a formal
hearing on May 3 in Munich, the European Patent Office ruled the patent was to
be maintained as issued, clarifying by amending one of 25 claims. Company
attorneys believe this amendment did not materially effect the scope of the
patent.
March 2007: E-messaging capability added to
Input/Loss Calculational Engine
Exergetic Systems has finished beta-testing of a new diagnostic package
associated with its Calculational Engine which allows automatic e-messaging of
instrumentation problems, plant efficiencies, general diagnostics, etc. This
Engine feature, developed by TQS Integration, will provide our clients with limited staffs
a wider and an easier
understanding of power plant performance.
October 2006: Exergetic Systems Forms New Marketing
Partnership

October 2006: Exergetic Systems to present at the
Symposium on Western Fuels International Conference
Fred Lang,
P.E. of Exergetic Systems; San Rafael, CA and Tom Canning of the Electricity
Supply Board; Dublin, Republic of Ireland will present the "Use of the
Oxy-Hydrocarbon Model of Fossil Fuels" at the Symposium on Western Fuels
International Conference on Lignite, Brown, and Subbituminous Coals
in Denver, CO on Thursday, October 26th. A draft technical
paper "An Oxy-Hydrocarbon Model of Fossil Fuels" is now available - comments are
invited (see Technical Papers).
September 2006: Exergetic Systems Forms New Marketing
Partnership
Exergetic Systems has formed a marketing partnership with Bill Smith, Jr., P.E.
of Exothermic Engineering; Liberty, MO. Bill has been practicing professional
engineering for 34 years and has developed many relationships in the power
generation industry. Exothermic Engineering is a consulting engineering firm
focused on combustion improvement work and solving performance problems in
coal-fired power plants. Exergetic Systems is pleased to have formed this
partnership with Bill and looks forward to his assistance in expanding its
product reach.
August 2006: Exergetic Systems Continues Beta-Testing
Its Oxy-Hydrocarbon Model
As announced in May, the Company released its Input/Loss
Method Version 2.8, Mod. 10, based on the new OHC Model. Beta testing at five
Input/Loss sites continues (two peat burning, two PRB and one high energy). The
OHC Model provides a genetic understanding of fossil fuels and eliminates
reliance on "reference fuel chemistries". Patents are pending in the U.S.,
Canada, Australia, and with the EPO. A draft technical paper "An Oxy-Hydrocarbon
Model of Fossil Fuels" is now available - comments are invited (see
Technical Papers).
August 2006: Exergetic Systems Awarded Installation of
the Input/Loss Method at Five Lignite Plants
ASPO Technology
of Athens, Greece and its partners Exergetic Systems and TQS Integration of
Waterford, Ireland have been awarded a contract from the Public Power
Corporation of Greece for the installation of five Input/Loss Methods at the
Agios Dimitrios Power Station, for monitoring and improving thermal performance.
These units range from 300 to 375 MWe, burn lignite, and are located in Northern
Greece.
