Venting Steam: The Largest Energy Loss in Steam Systems

Identify and mitigate the sources of steam loss to optimize your steam heating system.
Kelly Paffel, Inveno Engineering LLC

No Comments

With today’s competitive international market, all plants need to reduce operating costs, and lowering energy consumption can have a positive impact on the bottom line. A plant’s steam and condensate systems cannot afford to vent any utility steam, blowthrough steam or flash steam to the atmosphere. An additional benefit of not venting steam is a significant reduction in emissions in the boiler operation.

How to Eliminate Steam Venting and Stop Major Energy Losses

Recovering flash steam rather than venting it to atmosphere allows process plants to avoid energy losses from process steam systems. The techniques used to recover flash steam depend on the steam system design and process steam demands.

Lowering energy consumption can have a positive impact on the bottom line, and all plants can benefit from reduced operating costs. Any steam venting from the steam and condensate system is the top reason for lost energy in today’s steam systems.
