Waterhammer in Steam Systems

Administrator — Mon, 01 Oct 2007 20:38:56 +0000

Water hammer is not only a system issue; it is primarily a safety issue. Understanding the nature and severity of water hammer in a steam and condensate system, will allow facilities to avoid its destructive forces.

This greater understanding should also help with introduction of preventative measures into system designs, steam system startups, maintenance and installations, which help provide maximum safety for personnel, reduce maintenance cost, and reduced system downtime.

Upflow in a Vertical Condensate Pipe

Ten — Fri, 27 Jul 2007 11:24:03 +0000

How feasible is an upflow in a vertical condensate pipe without using a pressurized (flash) tank?

Please assume modulating steam conditions: ~60.000 to ~6.000 lbs/h steam consumption @ 100 psi, ~10% flash steam @ 15 psi.

Boiler Efficiency

Great web site for calculating boiler efficiency.

” Quoted from the web site” Natural Resources Canada has developed an online Boiler Efficiency Calculator to help managers quickly analyze the efficiency of boiler operations associated with heating and steam plants fired by natural gas and fuel oil.
