If a measured steam pressure falls below the setpoint, the PID increases the boiler firing rate, and conversely if the measured steam pressure rises higher than the setpoint, the PID will decrease the firing rate demand.
Steam is greener than many realize, and additional fuel sources like hydrogen and even ammonia may become a more viable way to fire a boiler to provide steam.
Following BOILER 2022, I was in awe of what we accomplished with planning and executing a new conference and trade show coming out of a global pandemic but realized we needed to quickly transition to how we were going to top the inaugural event.
The installation of Weil-McLain SVF 725 boilers at St. Paul Catholic Church not only addressed the immediate heating needs of the church but also positions them for future hot water requirements.
There are many misconceptions around achieving highly efficient operation from hydronic condensing boiler systems. The reality is, various factors will influence the operational efficiency of boiler plants.
