COMBINED HEAT AND POWER

COMBINED BENEFITS OF
DISTRIBUTED COGENERATION
Increasing demand for energy and long transmission distances from
power plant to end user affect the reliability of the electricity supply,
and also put pressure on the price of electrical and thermal energy. The
power and energy market has been deregulated and liberalized, pushing
power generation towards a decentralized model. More and more power
and heat is being produced close to the point of consumption. At the
same time, the world is calling for more efficient use of fuels to protect
the environment for future generations.
Wärtsilä addresses these demands with its Combined Heat and
Power (CHP) solutions for utilities, IPPs, industry and municipalities.
Typical plant sizes range from 4 to100 MWe, in single or multi-engine
configurations.
The combination of high efficiency and low emissions offered by
Wärtsilä CHP plants is unequalled in the market. Wärtsilä engines as
such comply with various national and local environmental requirements
and with World Bank guidelines for power plants.
Cogeneration is a closed process that requires no auxiliary cooling
of the engines since the heat from the process is taken into profitable
use. CHP plants, with their unbeatable electrical efficiency and high
total efficiency throughout the load range, have very low CO2 emissions,
so they easily comply with the most stringent environmental and CHP
regulations.
Wärtsilä CHP plants can run on various grades of natural gas and
liquid fuel, while still maintaining low emissions and high efficiency. The
plants include thermal heat recovery for hot water, steam, direct-fire hot
air, or chilled water – raising an already efficient power plant, 43-45%
in terms of net electricity, to a total efficiency of 90% or above. More
efficient use of fuel also translates into lower emissions per unit of fuel.

Where the building site is ample and not situated
in the midst of a densely populated area, the
single floor plant layout with an overall lower
plant profile is used. The main heat recovery
system is situated outside the main engine hall,

When the plant is situated in the middle of a
city or an industrial plant site, the layout is more
compact and the protective shielding is stronger.
The two floor plant lay-out allows a small and
compact footprint. The exterior of the plant and
possible architectural design of the power house
has also to be suited to its surroundings. The
emission levels have to be kept very low with
effective emission reduction systems and heavyduty silencers have to be installed to eliminate
any noice problems.

CUSTOMER CARE
Wärtsilä’s aim is to ensure that customers
obtain the best possible performance from
their power plant investment throughout its
lifecycle. After all, who could be better at this
than the people who designed and built the
plant?
Wärtsilä provides a comprehensive range
of services built on the concept of enhancing
the customer’s profitability by optimizing all
aspects of the power plant operation.
The services range from rapid spare
parts delivery to a complete operation and
maintenance partnership, allowing the
customer to focus on their core business.
10
Wärtsilä Operations & Maintenance currently
runs more than 130 plants around the world,
making it the world’s leading power plant O&M
contractor.
If customers choose to operate the plant
themselves, they can still rest assured that
they have the best possible support available
as and when needed – from training and
on-line support to service packages or plant
modernization and upgrading. Wärtsilä’s
global network is always ready to make sure
the power plant performs flawlessly, free
of breakdowns and unwanted downtime
throughout its lifetime.
COMBINED CYCLE SOLUTIONS
Wärtsilä’s combined cycle solutions with
reciprocating engines reach plant efficiencies
far above 50%. This is achieved by recovering
energy from the otherwise wasted heat
produced in thermal power plants, either by
using a conventional steam bottoming cycle
recovering hot exhaust gases or an organic
rankine cycle recovering heat from sources
with lower temperatures.

The purpose of Cheong Soo plant is to provide District heating and
electricity (CHP) to a newly established and build town with about
6400 house holds including public buildings. The CHP plant generates
electricity in parallell with the electrical grid and supplies the district
heating to the network for the town. During summer the plant provides
also district cooling.

a twenty-year power purchase agreement.
The trigeneration plant, generating a net electric power of 33 MW, is
connected to the airport’s internal grid and to the public grid. The plant
provides electricity continuously, as well as heating during the winter and
cooling during the summer.
