SKV40 Wood Chips-stack
Dong Energy Thermal Power is planning to implement district heating production based on biofuels through erection of a number of wood-chip boilers, providing steam for existing steam turbine and/or stand-alone district heating condensor. Two boilers are envisaged as an add-on to the existing gas fired plant, Skærbækværket. The new biomass fired boilers shall deliver up to 320 MW heat to the district heating system. It is envisaged that the new boiler plant shall have a capacity of maximum 280 MW and the remaining heat shall be provided by flue gas condensers.
In normal operation the steam will be fed to an existing turbine. It will also be possible to operate the whole plant only producing heat through by-pass operation to the stand alone by pass condenser.
Fuel will be wood chips. Recycled wood will not be used. The fuel specification will be included in the Invitation to tender.
The intention is to provide the boiler with an SNCR system for NOx reduction.
The boilers will be equipped with a complete flue gas treatment system consisting of bag filters to clean the flue gas before the flue gas condensers.
Concerning installation of the stack:
The civil works contract concerns:
— removal of existing chimney pipes
— supply and installation of new chimney pipes
— refurbishment of the existing stack in connection with installation of new chimney pipes
— supply and installation of interface ducts for the flue gas from the plant
— other consequential mechanical installations at the stack
— service and maintenance of chimney pipes
The material of the chimney pipes shall be either steel or fiberglass.
The existing concrete structure of the flue gas stack for unit 2 can be re-used for handling flue gas from the new biomass boilers.
The stack is approximately 120 meters high.
Flue gas specifications (flow, temperature, pressure, moisture content etc.) will be stated in the tender documents.
