WHRPP on Engine Exhaust Gases
Offered By Division T1

TESPL offers “Waste Heat Recovery Power Plants” (WHRPP) on Engine exhaust gases. The waste heat from exhaust gases is recovered to generate steam/Hot oil which in turn is used to generate electric power. Various available options for power generation include Steam Ranking Cycle Power Plants & Organic Rankine Cycle Power Plants. TESPL is experienced in designing customized and turnkey solutions of WHRPP on Engine Exhaust Gases to optimize power output and customer’s process requirements.


Huge amount of heat energy is rejected to the atmosphere through exhaust gases. The heat energy rejected to atmosphere through exhaust is to the tune of 28-35% of the fuel combusted in the engine. For a total installed capacity of 12 MW and above, the quantity of heat rejected is substantial and the option of secondary power generation through installation of WHRPP on Engine Exhaust gases becomes viable.

This waste heat from exhaust gasesis converted in to useful forms like steam/hot oil by installing waste heat recovery system: -

  • Electricity generation through Steam Rankine Cycle power plant
  • Electricity generation through Organic Rankine Cycle power plant

Reference installations

TESPL already has successful installations in operation for many years.
