Cogeneration Waste Heat Recovery at a Coke Calcining Facility
Abstract
PSE Inc. recently completed the design, construction
and start-up of a cogeneration plant in which
waste heat in the high temperature flue gases of
three existing coke calcining kilns is recovered
to produce process steam and electrical energy.
The heat previously exhausted to the atmosphere is
now converted to steam by waste heat recovery
boilers. Eighty percent of the steam produced is
metered for sale to a major oil refinery, while
the remainder passes through a steam turbine
generator and is used for deaeration and feedwater
heating. The electricity produced is used for the
plant auxiliaries and sold to the local utility.
Many design concepts were incorporated into the
plant which provided for high plant availability,
reliability and energy efficiency. This paper
will show how these concepts were implemented and
incorporated into the detailed design of the plant
while making cogeneration a cost effective way to
save conventional fuels. Operating data since
plant start-up will also be presented.
