In line with the vision to offer energy services throughout the life of an energy asset, EnergyWorks builds Distributed Power Plants, Co-Generation Plants, Combined Cycle Power Plants and Waste Heat Recovery Plants on turnkey basis while offering a full-fledged long term supply of spares & services including skilled manpower thus protecting investment of owners on one hand while on the other hand, operating & maintaining plants at most optimum levels. This integrated single window approach is a compelling proposition.

Right from sizing of power plant from varied considerations like plant loads on one hand to environmental conditions, choice of fuel, grid codes and future demand projections, EW puts together best practices in every area of engineering to pull off most efficient power plants built on modularity, scalability and flexibility.

Gas & Steam turbines, Heavy Fuel Oil / Diesel / Gas Engines, HRSG, Boilers, Chimney, Water Treatment, Cooling Towers, Cooling Pumps, Electrical Control & Instrumentation, Sub Stations and its integrity using latest Design tools, Quality Assurance programme, Conformance to international standards, Factory testing to construction at site through Field Quality Plan, assembly, commissioning & handover. EWs maintenance team takes over the operation on behalf of owner seamlessly providing key services like boroscope inspection, hot section inspection and overhauls in case of turbines as an illustration.

A typical CoGen plant with a Gas Turbine providing electricity, thermic fluid heating, steam, hot water for chilling

Gas Turbine is used to generate power of 7,233 KWe at 100% load and waste heat carried by the flue gases is recovered to heat the thermic fluid up to 240 Deg C, followed by generation of saturated steam at 10.54 bar and remaining heat is turned into chilled water to cool inlet air to gas turbine. In stage 1, flue gas at 513 Deg C is passed through the TF-HRU where it heat Thermic Fluid from 220 Deg C to 240 Deg C utilizing about 2 million Kcal of energy. Stage 2 recovery involves flue gas at 434 Deg C after the TF- HRU passing through boiler for steam generation utilizing about 7.6 million Kcal. Stage 3 turns remaining heat from the flue gas into supply of hot water for chilling in a VAC, which maintains the inlet temperature of gas turbine at 15 Deg C. Heat Balance Diagram shown below will explain this solution with CoGen efficiency of 84.7%.
