The security of a reliable steam boiler that’s always operational.
At Italian hospitals, especially the older ones, steam is commonly used for many purposes, from heating to canteen services, and sterilization.
Sterilization, canteens, and heating require high and extremely variable steam flow rates, resulting in considerable inefficiencies.
In fact, the steam often needs to be transported through an extensive distribution network, while being maintained at high temperatures (around 190 degrees).
And the more extensive the network, the greater the losses due to heat dissipation.
The result is a drastic decrease in the efficiency calculated for the entire system.
In order to improve these inefficiencies, hospitals often need to undertake major upgrades.
Do you want to improve your production line’s performance?
The problems of the thermal system at the Borgo Roma hospital were similar to those described above.
Major inefficiencies due to the use of steam in processes where it wasn’t necessary, and a system that hadn’t been optimized for the different seasons and time frames.
Although well insulated, the extensive distribution network and the old boilers with limited modulation capabilities were jointly responsible for the poor efficiency.
After analyzing the steam requirements over the span of one day, and later over an entire season, we realized that they varied continuously.
The new system, therefore, had to be able to handle both the higher demand volumes in the morning and the lower demand volumes in the evening.
Since the facility is a hospital, a highly reliable system was needed, as any steam flow blockages or interruptions could have dire consequences.
This implied the installation of an electronic system to control the entire system, to which our engineers could connect via the Internet for performance monitoring purposes.
The solution was designed to ensure optimal integration with the existing plant.
The solution adopted for the Borgo Roma hospital involved the introduction of one boiler for hot water production and three boilers for steam production.
Proportionate solutions with separate water and steam boilers allow for a considerable reduction in dissipation, thus improving overall efficiency.
We began by decreasing the total amount of steam consumed, by eliminating that which was formerly used for heating.
The remaining steam was that which was considered most important.
In fact, it was used for the canteen services and, more importantly, the sterilization processes.
System reliability was the keyword underlying all of the hospital’s requirements.
The remaining steam needed for the entire hospital to function properly had a flow rate that varied considerably based on the different seasons and time frames.
Therefore, in order to improve the entire system’s performance, it was also necessary to include a smaller boiler to handle smaller loads and to compensate for the load variations, in addition to the boiler for hot water production and the 2 large boilers for steam production.
In addition to this, a system for the cascade management of all the boilers was needed, so that they would only be turned on if necessary.
And what model could perform this task better than our very own EcoVapor?
Thanks to the high degree of modulation provided by its integrated burner, the EcoVapor allows for daily steam production to be managed more efficiently.
The EvoVapor also features advanced electronic components that are capable of managing all the other boilers in cascade, while at the same time monitoring their performance parameters and transmitting them to our engineers via the Internet.
The EcoVapor, therefore, monitors your plant room for you.
The efficiency of the individual boilers is high and exceeds 94% on average, but that which makes us even more proud of the service we provided to the customer is the improvement of the entire system’s performance, in addition to that of the individual boilers.
The continuous monitoring of the system guarantees that the performance is maintained over time, avoiding any deviations from the optimal parameters.
The data collected over the course of the entire calendar year will allow us to validate the partial results obtained so far.
The high load modulation and the “smart” steam production will provide for considerable annual savings on natural gas costs.
For us, cost savings and the use of innovative production technologies have always been a must, and we’re now looking forward to completing the innovative projects at the Borgo Trento and San Bonifacio hospitals.
We know that continuous innovation can be complicated.
