Ecosesto SpA, coordinated by Actelios Spa, ordered to W.T.E. the design and the supply of a superheated steam boiler and auxiliary equipment for a power plant, located in Rende (Italy), fed by wood chips and olive residues. The plant was undergoing a complete revamping system in order:
1) to increase efficiency of energy recovery and
2) to allow complying with the requirements of European Union regulations concerning the obtaining of the status of IAFR (Plant fed by renewable fuels) basing on Italian regulations.
W.T.E. replaced the convective pass of existing boiler, supplying new convective bundles (economizers, evaporators, superheaters), designed according to the new operating conditions.
Moreover, a new low temperature economizer was added. The air/fumes exchanger used to preheat combustion air has been replaced. A new shell and tube heat exchanger has been installed. Additional interventions concerned
1) the supply of a new thermo-physical degasser 2) improvements to the furnace and the radiating
pass such as: replacement of the slag discharge hopper; renewal of the refractory lining.
