Steam System Losses: Five Places to Look Before Buying New Boiler Capacity

Why this matters in food manufacturing A boiler that appears short of capacity may actually be feeding avoidable distribution and process losses. Before investing in additional steam generation, establish when pressure collapses, where it collapses and what demand is active at the time. Trend boiler output, header pressure, make-up water, condensate return and major user operation. Capacity decisions should be based on measured peak demand and recovery behaviour, not operator perception alone. 1. 1. Failed steam traps Failed-open traps pass live steam into condensate systems; failed-closed traps flood heat exchangers and reduce heat transfer. Both can look like a capacity problem. Create a trap register and test using temperature, ultrasound and operating context. Prioritise high-pressure and large-orifice failures because their loss can be material. 2. 2. Poor condensate return Hot condensate contains valuable heat and treated water. Low return rates increase boiler fuel, water treatment and make-up demand while potentially hiding leaks or failed equipment. Measure return percentage and investigate where condensate is intentionally or unintentionally discharged. Check flash steam recovery opportunities and contamination risks before changing return arrangements. 3.…
