Combustion Engine Performance

TGPS has conducted several dozens of combustion engine performance test around the world. Our thermal performance engineers has experience evaluating the combustion engine efficiency of different OEMs such as MAN, Hyundai, Caterpillar, Wärtsilä, B&W, among others. The purpose of the combustion engine performance test can vary, from contractual reasons to diagnostic purposes, such as understanding changes in the combustion engine heat rate.

Our performance testing company strictly follows the ASME PTC 17, ISO and DIN test protocols. These protocols are universally accepted as methods to measure the combustion engine heat rate and/or generator output in a reliable manner.

TGPS holds a large amount of precision testing instrumentation to evaluate the combustion engine efficiency. These instruments are used to reduced the performance testing uncertainty of the combustion engine heat rate or combustion engine power output results.

Combustion Engine Heat Rate

Probably the most important parameter in a combustion engine is the combustion engine heat rate, which is a relationship of fuel consumption and electricity production. It is important to consider the importance of monitoring this parameter during the entire life of the combustion engine and the project. Recently, several cogeneration projects select the combustion engine as the prime mover of the cycle for it’s flexibility and efficiency for industrial applications.

Performance Test Procedure

For a combined cycle performance test, there are certain specific items to place special attention in the combined cycle performance test procedure.

  • Combined Cycle Isolation (thermal and electrical isolation)
  • Test Boundaries Definition
  • Combined Cycle Performance Guarantees
  • Testing Instrumentation
  • Calculation of final Combined Cycle Performance

TGPS has a diverse range of experience, not only in the CC configuration, but also in complex evaluation of projects that occurs in a multi-stage testing program as defined in the ASME PTC 46.

Acceptance Test vs Diagnostic Test

Depending on the objective of testing certain parameters are more critical than others. Only an experience power plant performance engineer can guide the process through the most efficient path to achieve the specific objectives. For a contractual performance test topics such as test uncertainty, performance guarantees are more relevant. In a diagnostic test, not only these parameters are important, but also looking to historical trends, power plant upgrades, operation modes, load cycling, among others. Our team uses the latest tools to diagnostic the combined cycle performance in an accurate and practical way. Results that can impact directly the combined cycle efficiency.

Why is Power Plant Efficiency Important?

Power Plant Efficiency is directly correlated to the business sustainability in terms of financial performance and long-term feasibility.
