Cogeneration Solution for Commercial Buildings

Solution provided with both Gas Turbines / Reciprocating engines.

Absorption Chillers (VAM) are installed on the exhaust of Gas Turbine or Gas Genset to produce chilled water. Chilled water is used in the commercial complex to produce air-conditioning. Thus heat energy from the exhaust is converted to useful energy saving total power requirement to otherwise run electric chiller.

Application: Buildings, malls, IT parks, Data Centers, Airports, Hospitals and specific Industries such as Spinning mills are prospects.

Solution Advantage:

  • Reliable source of energy
  • With Cooling and heating requirement of modern buildings upto 70% of the total power requirement, energy bills upto 50% reduction can be achieved
  • Surplus power produced can also be sold to grid
  • Improved quality of power supply

Cogeneration Solution for Industries:

Solution provided with both Gas Turbines / Reciprocating engines.

Steam / Hot water / Thermal oil – heat recovery medium is installed on the exhaust of the Gas Turbine or Gas Genset. This way Heat and Power are produced simultaneously resulting in high overall efficiency upto 85%. The solution is customized for each project

Application: Textile, paper, chemical, pharmaceutical, tyre, food and breweries, refineries, petrochemicals are major prospects.

Solution Advantage:

  • Reliable source of energy
  • Modular Approach-Depending on the power requirement proime movers can be used-with quick start-stop characteristics
  • Energy bills upto 50% reduction can be achieved
  • Surplus power produced can also be sold/freewheel to grid (depending on the country policy)
  • Improved quality of power supply

Waste to Heat & Power Solution

Solution provided with both Gas Turbines / Reciprocating engines.

Waste Material can be any of the following depending on Methane and Carbon dioxide content.

  • Municipal Waste-Liquid manure, Household Solid waste
  • Secondary-growth raw materials, e.g., corn silage, non-food grains
  • Sewage sludge and grease sludge
  • Biowastes from slaughter houses
  • Breweries and distilleries, fruit and wine press houses
  • Cellulosic wastes from Sugar and Dairy factories

The organic material is collected and sterilized to remove harmful germs and moved to the digester. The biogas produced in the digester is collected in a gas storage tank to ensure a continuous supply of gas independent of fluctuations in the gas production. Finally, the biogas is fed into a machine.

The end product from the fermentation of the biomass can be utilized as fertilizer.

Solution Advantage:

  • About 60-80% of Municipal waste utilized-reduces land requirement, transportation costs, environmental costs
  • Environmental friendly solution-biomass is a CO2-neutral, renewable energy source
  • Highly efficient for on-site power and heat generation
  • The remaining substrate from the digester can be used as high-quality, agricultural fertilizer

District Cooling (we can convert this to heating)

A central cooling plant supplies chilled water to multiple buildings / district. Hybrid configuration of Gas Turbines and Gas Engines is used in District Cooling Plant (DCP) so as to provide both Base Power & Peak Power.

There can be many DCPs distributed across the cities. Each DCP has its own Co-gen. All DCPs are grid connected. Direct exhaust fired Absorption chiller preferred.

Solution Advantage

  • High load factor on chillers due to better load management-high operating efficiency
  • Reduces investment and space on individual buildings for chillers, etc.
  • Power Savings through water cooled chillers
  • Modular Approach-Depending on the power requirement Machines can be used-with quick start-stop characteristics
  • Use of expensive Natural Gas more efficiently
