WHRS on Gas Turbine
Offered By Division T1

TESPL offers Turnkey Waste Heat Recovery Power Plants (WHRPP) and Waste Heat Recovery Systems (WHRS) on GasTurbine exhaust gases. 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 depending on the temperature of heat source. Apart from electric power, TESPL also has experience in designing customized and turnkey solutions of WHRPP and WHRS on Gas Turbineto offer various other outputs for process use.


Huge amount of heat energy is rejected to the atmosphere through exhaust gases. The heat energy rejected to atmosphere is to the tune of 60% of the fuel combusted in the gas turbine. Therefore,a Turnkey WHRPP and WHRS on Gas Turbine exhaust gases becomes viable.

This waste heat can be converted in to following useful forms by installing WHRS:-

  • Steam / Thermic fluid (hot oil)/ Hot water for process use
  • Generation of electricity through Steam Rankine Cycle power plant
  • Generation of electricity through Organic Rankine Cycle power plant
  • Chilling up to +6 deg C
  • Refrigeration up to -60 deg C
  • Waste water Recycling
  • Different Drying applications in Process

Reference installations

TESPL has many successful installations in operation for many years. One of the pioneering and path breaking projects of WHRS on Gas Turbines executed by TESPL is quintuple generation plant using gas turbine cogeneration cycle. This WHRS on Gas Turbine is a process integrated cogeneration project generating five different forms of energy from single heat source i.e.Electricity, Thermic fluid for process, Chilling, Steam for waste water recycling (including Spray drying for Zero liquid discharge).
