Say "no" to suction strainers for condensate return and

Aug 20, 2018 · Volume 5/ Issue 2/ August 2018 Condensate return and boiler feed unit specifications frequently call for a strainer to catch particles that could damage pumps. Basket strainers or "Y" strainers are equally effective, as long as they're properly located and maintained. Suction strainers, on the other hand, aren't a good idea. They made sense inRead more

Steam Basics Part 12: Steam & Condensate Strainers

Mar 28, 2017 · The steam traps in condensate systems require larger openings. We suggest .045 perf up to 2" and .125 perf above 2". Condensate pumping systems normally have a strainer at the inlet of the condensate tank. Your client is best served if this is a basket strainer. Normally condensate units serve many areas or a main heating heat exchanger system.

The Feedtank and Feedwater Conditioning | Spirax Sarco

The return of condensate represents huge potential for energy savings in the boiler house. Condensate has a high heat content and approximately 1% less fuel is required for every 6°C temperature rise in the feedtank. Figure 3.11.5(a) shows the formation of steam at 10 bar g when the boiler is supplied with cold feedwater at 10°C.

Returning Condensate and When to Use Condensate Pumps

A pumping system is required to transport and recover condensate once the system backpressure becomes higher than the lowest possible trap inlet pressure. System backpressure can be calculated by totaling the sum of 3 discharge side components: Lift after a steam trap, pump, or pump/trap; Frictional loss of the transport piping

Steam Condensate - an overview | ScienceDirect Topics

Steam–condensate thermal engineering systems are applied in numerous industrial sectors. A scheme of a simple open conventional steam–condensate system is given in Figure 5.6.The steam produced in the boiler house is transported via pipelines to the heat consumers (heat exchangers; heat apparatus), where the steam condenses. At the exit of the heat exchangers, condensate batteries

Deaerators in Industrial Steam Systems

Deaerators provide the water storage capacity and the net positive suction head necessary at the boiler feed pump inlet. Returned condensate is mixed with makeup water within the deaerator. Operating temperatures range from 215° to more than 350°F, which reduces the thermal shock on downstream preheating equipment and the boiler. Insulation
