Boiler Efficiency and Steam Quality: The Challenge of

For example, if a process of which steam consumption is only 5% of boiler output is turned on rapidly (such as with an on-off valve), the system demand can easily increase by 15% or more until the process reaches a steady state of operation. When a steam valve opens, two problems occur in the boiler. First, steam pressure drops rapidly.
