Ospedale di Borgo Roma, Verona (IT)

The university hospital of Borgo Roma is one of the 2 hospitals in the city of Verona and is second in Italy for the number of beds and fifth for the number of hospitalizations.
 
NEEDS:
 
Sector
In many Italian hospitals, especially in older ones, it is common to have unique steam systems for space heating, instrument sterilization and canteen service.
If for some of these processes it is necessary to have steam at high temperatures, to heat the rooms it is sufficient to use hot water.
By dividing the heating system into 2, steam line and hot water line, a significant increase in overall thermal efficiency can be obtained.
 
Customer
The Borgo Roma Hospital has a heating system managed by an external ESCO (Energy Service Company).
In this case we are talking about Carbotermo, a company specialized in the design and construction of heating and cooling systems.
As a heat manager, Carbotermo is particularly attentive to the global efficiencies of the heating system, as well as those relating to management and maintenance processes.
The new thermal power plant therefore not only had to have high yields, but also had to be simple to manage and highly reliable as a hospital structure.

THE NEW THERMAL SYSTEM

The Borgo Roma Hospital has a vast and widespread heat distribution network.
Despite the substantial investments made over the years to thermally insulate the distribution network, this still remains a source of inefficiencies.
By analyzing the needs of hot water and steam over the course of the day and the seasons, we realized the high variability of the volumes required by the hospital.
This imposed the need to effectively "manage" the low requests for steam and hot water recorded for certain time slots in certain months of the year, such as the evening ones in the summer months.
To do this, we used our E-term electronic control system to constantly analyze the hospital's needs, manage the switching on of the various generators in cascade and
monitor their performance.
The technical characteristics of e-term and the high modulation capacity of our Ecovapor integrated steam generator allowed us to increase the overall efficiency of the thermal power plant by better "supporting" the demand curves.
 
The plant
1. 3 steam generators with modulating burners, vertical economizer and 72h continuous supervision system.
2. Industrial boiler for hot water production with modulating burner and economizer.
3. Ecovapor + electronic system for cascade management of the plant, completely automated.

THE RESULTS

The efficiency of the boilers if taken individually exceeds, on average, 94%, but Carbotermo's objectives were and still refer to levels of efficiency and pollution, reported by the new concept of thermal power plant.
In fact, the new plant is ensuring better overall yields thanks to the high modulation of the new combustion systems, with a more efficient management of the various daily and seasonal needs.
The new steam and hot water generators have led to a considerable reduction in the NOx levels emitted by the plant, reaching values below 100mg / kWh.
In addition to the improved efficiency achieved, the system is connected live to our servers, allowing faster monitoring and maintenance actions.
