Gilegno

Manager: Gilegno di Grossoni Ernesto & Figli Snc
Location: Sommalombardo (Varese, Italy)
Plant: 1 x ZE-100-LT ORC energy production module
Application: Primary energy production in combination with a boiler burning wood chips


Gilegno MappaThe Gilegno firm, from Sommalombardo - a small town in the province of Varese, not far from Malpensa airport - is a sawmill which has decided to convert their processing residues into energy. The wooden residues are converted into chips and then burned inside a movable-grate boiler which supplies overheated water to the ORC module which, in turn, transforms that thermal energy into electricity.

The ORC system supplied by Zuccato Energia, Texas Green Technologies' Italian partner, is  a ZE-100-LT module connected to the boiler via an overheated water loop, and hosted under a large lean-to.

One of the peculiarities of this system is that residual heat from the condensation stage of the ORC is used to dessiccate the wood chips before conveying them to the boiler, thus increasing their heat value. Another peculiarity is that, given that the location of the firm skirts a residential area, the skid has been enclosed in a sound-absorbing enclosure, to drop the already low noise emissions almost to zero. The electricity produced by the plant is oputput to the national grid, as usual.

The fuel this plant uses are wood chips, i.e, bark and wood bits shredded into small chips by specific machinery. Given that this material is derived from virgin, untreated wood which has undergone purely mechanical processing, it is considered as biomass and a renewable energy source.
