Feasibility study to convert a furnace, fed by diesel oil, to RDF (Refuse Derived Fuel), throughput 150 MWe

W.T.E. designed a mathematical model based on characteristics of existing boiler and suitable to describe air suspended fuel burning and energy recovery in combustion chamber.

Reduced steam thermodynamic parameters were assumed in order for the boiler tubes to sustain corrosion phenomena. Following, the off-design boiler operations were evaluated.

New models describing actual performance with oil were tuned and validated. These models have been used after positive tests to describe new configurations.

The design of a new RDF warehousing, the RDF handling, the choose of new suitable burning systems were also included in the scope of work.

The new fuel required a deep performance analysis about the gas cleaning system. A modification of the existing equipment with new sections has been engineered in order to comply to more stringent rules on environmental emissions.

A budget price of the revamping was also delivered.
