Gaec des Friches (56): regular maintenance for maximized cogeneration
Gaec des Friches (56): regular maintenance for maximized cogeneration
An engine that achieves up to 99.4% productivity
The Gaec des Friches, in Saint-Nicolas-du-Tertre (France), operates a biogas plant, now structured around two cogeneration engines: a Deutz V8 with a capacity of 260 kWe, operational since 2015, and a MAN Rollo V12 350 kWe, commissioned in 2017. These facilities were designed and implemented by a German integrator. Coupled with the work of the integrator, the regular maintenance of the installation by CHAPLAIN Energie allowed the Deutz engine to post a record availability, at the end of the first year of operation. In fact, the V8 had 8,707 operating hours, a productivity of 99.4% and an injection average of 248 kWe / h!A feat all the more notable as the process feed is very heterogeneous: Gaec by-products – livestock effluents, intermediate crops – and external inputs: straw, vegetable waste, etc. In connection with the ramp-up of its installation, the operator has also signed a waste recovery plan for the waste from the Yves Rocher production site, located 10 km away.The nature of the biogas, which varies according to inputs, is analyzed every 250 hours. The concentration of certain elements makes it possible to target the organs of the process showing signs of fatigue. This preventative maintenance provided by CHAPLAIN Energie plays a key role in preventing unplanned shutdowns of the installation. If necessary, the Gaec has a hotline, with remote control of the installation. If necessary, the CHAPLAIN Energie technician arrives in less than 4 hours, 24 hours a day, 7 days a week.
Professional words: « Optimized maintenance costs »
« Once the Gaec des Friches facilities were in place, our mission was to turn the knobs to start them, and then monitor their operation, » explains Romain Chamard, Chargé d’Affaires Grand Ouest cogeneration at CHAPLAIN Energie. We provide maintenance for both engines, during a single visit, which optimizes the maintenance costs which represent both the guarantee of the performance of the installation and a major expense item. As such, the Gaec plans to entrust us with the follow-up of a new project engine. « chaplain energy
