Kotka Energy 

Kotka Energy
has launched their utility power plant project after obtaining a lawful
permission for the plant. ALSTOM Finland Oy will supply a complete flue gas
cleaning system for the plant. The delivery comprises a NID system based on the
semi-dry technology, flue gas fans, silos and flue gas ducts.


The erection work at the site will begin in the summer of 2007, and the
start-up of the flue gas cleaning plant will take place in the summer of 2008.
The flue gas cleaning system meets all the stringent emission limits defined in
the EUs new waste incineration directives.


Boiler plant power is 36 MW. The main fuels are municipal solid waste,
industrial energy waste, and demolished and recirculated wood. The total
quantity of waste fuel to be fired is approx. 100,000 tons a year. The
incineration plant will supply industrial steam and produce heat to the
district heating network in the Karhula area as well as electricity to the
national network.

Ekokem Oy Ab will
invest in a new flue gas cleaning system for lines 2 and 3 at their
incineration plant in Riihimäki. ALSTOM Finland Oy will supply the complete
flue gas cleaning system, which will be delivered on a turn-key basis
comprising of  flue gas ducts, district heating economizer, semi-dry NID
system, flue gas fans, silos and stack.


On incineration line 2, the waste is burned in a high-temperature rotary kiln
(1200-1350^oC) and on incineration line 3 in a medium-temperature
rotary kiln (500-850^oC). The waste to be burned on these lines is municipal
solid waste, solid and industrial waste, contaminated and treated wood, metal
and electronics scrap and different types of hazardous waste. Line 2 has a
waste-handling capacity of 33,000 tons a year and line 3 a capacity of
8,000-40,000 tons a year. The energy produced by the incineration of hazardous
waste is utilized for the production of district heating and electricity.


The erection of the flue gas cleaning system at the site will begin in February
2007 and test run in August 2007. The plant will be started up in the autumn of
2007. The new flue gas cleaning plant meets all the stringent emission limits
defined in the EUs new waste incineration directives, and partly the emissions
will be even lower.
