Heat Exchanger Troubleshooting Short Course

Course Fee: US$650

Design decisions can have a costly impact on heat exchanger operation. Learn by reviewing several real cases in which unit designs had critical commercial consequences for operators/ owners. In some cases, the units did not work in service; in others, the designs were revamped before the units began operation.

Each case study is introduced as a problem; participants work individually or in groups to determine the cause and develop solutions. Prior to each case, the instructor reviews related HTRI methods.

Key Topics may include:

  • Steam generator with tube failure
  • Intercooler with vibration concern
  • Condenser-subcooler with design flaws
  • Recuperator with performance shortfall
  • Economizer with convergence issues
  • Brine chiller with insufficient duty
  • Flooded condenser with inadequate subcooling
  • Air-cooled condenser with noncondensables
  • Once-through reboiler with instability
  • Vapor-liquid separation
  • Fouling with tube failure
  • Gas cooler with inadequate performance

Suggested Participants

Engineers—from novice to expert—who want to ensure that design problems are identified before operation

Upcoming Instructors

  • Hitoshi Miyamoto


  • Technical Representative, Japan, holds both a BS and an MS in Mechanical Engineering from Aoyama Gakuin University, Tokyo, Japan. Miyamoto retired after over 35 years with IHI Corporation, where he held numerous Project Manager and Project Engineering positions in LNG/ LPG, chemical plant, nuclear power plant (PW/BWR), re-processing plant, and pharmaceutical plant. Following his retirement, he continued to do consulting work for his former employer on heat transfer and fluid flow, air coolers, and LNG/BWR/PWR plant engineering projects. Miyamoto also served on the HTRI Technical Committee from 1999 – 2003. His knowledge of HTRI technology and decades of engineering expertise enable him to provide quality technical support and training to our customers in Japan. Miyamoto is a registered Professional Engineer and First Class Management Engineer in Design & Construction (Japan).


  • Siddharth Talapatra


  • Group Lead, Research, earned his MS and PhD in Mechanical Engineering from The Johns Hopkins University, Baltimore, Maryland, USA. During his graduate studies, he was a Research Assistant at the Laboratory for Experimental Fluid Dynamics, where he worked on projects involving turbulence, effects of surface roughness, fluid structure interaction, and oceanography using high-speed imaging, particle image velocimetry, and holography. His dissertation research focused on elucidating coherent structures in the nearwall region for a rough channel flow, and understanding the key biophysical interactions in the coastal ocean. Talapatra also holds a BS degree in Mechanical Engineering from Indian Institute for Technology, Kharagpur, India. At HTRI, his primary research responsibilities are focused on qualitative and quantitative flow visualization and laser anemometry to examine single- and two-phase flow inside pipes and heat exchangers. His research activities also include the study of shellside condensation, subcooled condensation, and thermosiphon reboiler turndown and instabilities. Talapatra is actively involved with HTRI’s training efforts, including development of new courses.
