Tube Failure Detection in Recovery Boilers

INTRODUCTION

Exergetic Systems was founded in 1982 as an employee-owned engineering firm (video timeline of Exergetic Systems' history). The company specializes in the improvement of power plant efficiency. The company's core work is divided into three disciplines: 1) on-line monitoring systems, 2) testing power plants for improved heat rate and 3) advising utilities at the system level as to improved thermal performance. The following points highlight these endeavors:

Exergetic Systems has completed over nearly three dozen major thermal performance evaluations of power plants including testing, detailed analysis and recommendations for heat rate improvement. These were major thermal evaluation efforts, exceeding ASME Power Test Codes 4.1 and 6 procedures. The average recoverable heat rate has been 446 Btu/kWh (1037 kJ/kWh) and 16 MWe.
Exergetic Systems has installed the Input/Loss Method at ten power plants. The Input/Loss Method allows instantaneous gross unit heat rate, updating of fuel heating values, fuel flow, total "Energy Released by Combustion", Fuel Consumption Indices, etc.; all on-line.
Exergetic Systems has the experience and expertise to make generic evaluations of all power plants on a utilities' grid. A typical application of this service resulted in identification of 2% improvement/unit for 5 units, and an average 6% improvement/unit for another 4 units. These results were demonstrated in only two months!

The company's core efforts have developed from a solid technological base, historically developed and fully integrated with the company's testing projects. This includes software simulators for the boiler and turbine cycle, computer interfaces, testing procedures, user's manuals, system calculational closure techniques, copyrights and US method patents. The bulk of this technology base exercises our Input/Loss Method. As stated 24 years ago when founded, our objective has, and continues to be, state-of-the-art Directed Development in thermal performance engineering.
