Energy Efficient Retrofit Solutions

We provide retrofit solutions for efficiency improvement

Steam Turbine R&M

Turbine Retrofit

We provide turbine retrofit solutions for efficiency improvement, life extension, operational flexibility, re-engineering & modernization. Our solutions can address performance deterioration and shortfall in efficiency of machine and help achieve enhance operational reliability. These retrofit solutions can be implemented through complete turbine shaft line replacement in the existing foundation or only by replacement of inner module in HP, IP and LP. This is complimented by high efficiency turbine blading developed by our promoter GE Power. The optimize solution can be tailor as per customer requirements, and both impulse and reaction technologies can be employed. We also have capabilities to provide individual cylinders solutions under our component retrofit programme. Our capabilities for life assessment studies, steam path audit provide necessary tools to developed customize solutions suiting each machine set.

Turbine Auxiliaries

We also provide turbine auxiliaries compatible to new solution or independent upgrade including state of the art governing system, condensate system, feed system, heaters & extraction system, lube oil system, HP-LP bypass system, etc. We also have solid experience in redesigning of critical pipes along with complete stress analysis for hangers & supports requirement.


  • Retrofitting turbines with new rotors, inner blocks and high-efficiency blades for heat rate improvement.
  • Improvement in system response by upgrading the electronic turbine governing system.
  • Improvement of turbine cylinders, rotors and bearing pedestal supports to achieve faster start up.
  • Performance optimization of condensers and vacuum improvement through effective on and off line cleaning, helium leak detection etc.
  • Re-powering with high efficiency turbines.

Steam Boiler R&M

We provide steam boiler & auxiliaries solutions for life extension, modernization, re-engineering & upgrade to address performance deterioration including effects of fuel degradation and shortfall in operational reliability with implementation of safety norms (BMS / FSSS) . We have in house capabilities to carry out complete computational fluid dynamics (CFD) studies to re-engineer & implement modification to ducts, dampers, expansion joint, etc. Our retrofit solutions bring unparalleled advantages in flexibility, and cyclic load management.
