AESPL

Base Line Testing & Performance Guarantee Test

Boiler performance test programs have been conducted with various objectives including baseline performance characterization, new and retrofit equipment acceptance testing, and combustion and pollution system tuning and optimization. AESPL personnel are highly familiar with ASME test procedures. Examples of test projects AESPL undertakes include:
