The customer, HZI, needed to construct a waste-to-energy (WtE) plant for electricity and heat production in the Helsinki metropolitan area in Finland.
The WtE plant has a nominal capacity of 99 megawatts (MWth) of district heat and 62 MW of electricity for the power grid. Waste is burned in two grate-fired steam generators and the electricity produced by a gas turbine and a steam turbine. The live steam from the WtE boilers is super heated before entering the steam turbine in a separate HRSG boiler of the gas turbine.
Citec provided engineering and documentation services through our concept local presence with cost-efficient global resources.
Citec’s scope included basic engineering for:
- Boiler support steel structures
- Service platforms
- Building frame (including secondary steel structures). Building steel weight of approximately 2000 tonnes.
We also provided input for detail engineering, for example:
- Steel overview drawings
- Static drawings
- Joint forces tables
We also delivered Calculation reports related to building permit requirements and also a part of the final documentation created for the customer and end customer.
Software tools used in the project include Global BIM software, PDMS 3D design and TEKLA structures.
