Insulated Steam Accumulators
Roben, Mfg, Inc. engineers and fabricates insulated steam accumulators providing peak steam demand management and process steam quality improvement. Our insulated accumulators feature high-temperature insulation systems that minimize heat loss during storage, enabling efficient steam buffering for batch processes, peak shaving, and load leveling applications.
What Are Insulated Steam Accumulators?
Insulated steam accumulators are pressure vessels designed to store high-pressure hot water that partially flashes to steam when pressure is reduced, providing supplemental steam during peak demand periods. Insulation systems minimize heat loss during storage, maintaining accumulator energy content and reducing makeup heating requirements.

Frequently Asked Questions
How does insulation affect steam accumulator performance?
Proper insulation reduces heat loss to 1-2% of stored energy per hour compared to 10-15% for uninsulated vessels. This maintains accumulator capacity during standby periods, reduces makeup heating, and improves overall system efficiency by preserving stored thermal energy.
What storage capacity do insulated steam accumulators provide?
Steam storage capacity depends on operating pressure range. Each cubic foot of water at 300 psig releases approximately 20 lbs of flash steam when reduced to 100 psig. We size accumulators based on peak demand magnitude and duration requirements for each application.
How is insulation designed for steam accumulator thermal cycling?
Steam accumulators experience thermal cycling as they charge and discharge. We specify resilient insulation systems, expansion joints in metal jacketing, and attachment methods that accommodate thermal movement while maintaining insulation integrity and weather protection.
