Challenge
The project presented several hurdles, primarily the need for a single chimney system to accommodate diverse installations and performance requirements. We overcame this by selecting Schiedel ICS and ICS 5000 double-wall stainless steel systems. Their universality and exceptional performance in terms of sealing, temperature resistance, and overpressure allowed us to cater to various coexisting installations seamlessly.
Another challenge was the existing cavities of the historic building, with extremely small spaces for duct installation and handling. Finally, all systems had to satisfy stringent fire prevention and compartmentalization requirements. Our certification for Fire Resistance with an EI 120 classification, according to the specific chimney standard UNI EN 1366 Part 13, ensured this crucial requirement was met.
Solution
The project's success hinged on the versatility, exceptional performance, comprehensive certifications, and straightforward design and installation of our Schiedel ICS and ICS 5000 systems. These attributes allowed us to deliver a uniform and rapid solution that perfectly aligned with all project requirements.
Schiedel proudly supplied and installed a high-performance, 450 mm diameter ICS double-wall stainless steel chimney. This impressive system supplies a collective of three 900 kW and two 670 kW condensing boilers, rising over 106 meters (26 floors) from the underground thermal power plant to the rooftop.
Additionally, we installed three 600 mm diameter ICS 5000 system chimneys for overpressure systems, serving as a pre-disposition for kitchen hood exhalation, also extending over 100 meters.
Finally, two ICS 5000 chimneys were dedicated to generator sets and a motor pump. This section presented a unique challenge due to its extensive horizontal route within the extremely confined basement spaces. This demanding segment proved to be a genuinely exciting design, construction, and installation challenge that the Schiedel team of professionals expertly conquered.
