Here is the energy analysis of the hydronic heating system
depicted in the diagram.
The boiler plant consists of two identical boilers, each having
the following characteristics:
• Fuel: natural gas
• Burner Type: on/off
• Rated Output = 85 kW
• Rated Efficiency, nFL = 80%
The boilers operate in a “Lead/Lag” arrangement, i.e., Boiler 1
operates first to meet the load (up to its capacity), and Boiler 2
operates as necessary to meet any remaining load.
The pump...
