Cogeneration means combined heat and power (CHP).
Cogeneration is defined as the sequential generation of two different forms of
useful energy from a single primary energy source.
It produces electricity and thermal energy at high efficiencies using a range of
technologies and fuels.
Cogeneration used for many years all over the globe across different industries in
several forms like steam boilers and steam turbines, gas turbines, reciprocating
engines, and heat recovery systems.
In Cogeneration, the fuel is used first to drive the prime mover to generate
electricity and produce heat.
The heat is then used to boil water and generate steam. Some of the steam is used
to support a process while the remaining steam is used to drive a steam turbine to
generate additional power.

Cogeneration is very efficiently helpful by using waste heat recovery technology to
capture wasted heat associated with electricity production.
Cogeneration systems typically achieve total system efficiencies of 60 to 80%.
For micro-cogeneration systems, the main output is heat, with some electricity
generation, at a typical ratio of about 6.1 for domestic appliances.
In the case of steam turbines, cogeneration technologies widely commercialized
include extraction and backpressure steam turbines.
The capital cost to build a cogeneration plant and the size of the plant required to
demand a constant load 24/7 for viability and financial advantages, but the main
advantage of this type of cogeneration is the long plant life for the steam turbines
due to low wear and tear.
In steam cogeneration systems the fossil fuels mostly used are coal, oil, and natural
gas.

Cogeneration is likely to be most attractive because the requirement of demand for
both steam and power is balanced which is consistent with the range of steam. And
also power output ratios that can be obtained from only suitable cogeneration.
Cogeneration is also most likely to be attractive for a single plant or group of plants
that has sufficient demand for steam and power to permit economies of scale to be
achieved.
Cogeneration also helps peaks and troughs in demand can be managed or, in the
case of electricity, adequate backup supplies can be obtained from the utility
company.
The ratio of heat to the power required by a site may vary during different times of the
day and seasons of the year.
Importing power from the grid can make up a shortfall in electrical output from the
cogeneration unit and firing standby boilers can also satisfy additional heat demand.
Turtle Turbines is one of the most reputed Steam Turbine Manufacturers In India.
Turtle Turbines has been in the business of supplying Steam Turbines for
Cogeneration and Micro Cogeneration.
Turtle Turbines has supplied numerous Steam Turbine Cogeneration plants across
India, South East Asia, and African Countries.
