Steam Systems

Ensure safe and reliable system performance while reducing steam usage, leaks and energy costs.

The steam generated by a boiler, or provided by a district or campus energy distribution system must be conveyed through pipework to the point where its heat energy is required.

Steam at high pressure occupies a lower volume than at atmospheric pressure. The higher the pressure, the smaller the bore of pipework required for distribution of a given mass of steam. When steam condenses, its volume is dramatically reduced, which results in a pressure reduction that enables the flow of steam through the pipes.

Advanced steam trap performance monitoring solutions for optimizing condensate system efficiency.

Steam traps are used to release condensate from the pipework while preventing the steam from escaping from the system. Poor steam trap performance can cause significant energy loss. When a steam trap fails open, steam is not completely consumed and is blown directly into the condensate return system. It can also raise the pressure in the condensate system, inhibiting the discharge of other traps, causing system-wide inefficiencies. If it fails closed, the system will flood, causing a loss of heat transfer. Steam trap failures also increase the potential for water hammer that may lead to equipment damage and downtime.

Online steam trap health monitoring solutions.

Periodic manual inspections of steam traps can result in weeks or months of undetected failures and leaks. Manual methods for acoustic listening are imprecise and expensive. With unparalleled temperature and ultrasonic measurement, the Rosemount™ 708 Wireless Acoustic Transmitter with its specialized Steam Trap Monitoring software monitors and identifies trap health and failures in real-time.

Engineered with WirelessHART technology, the Rosemount 708 accurately communicates your acoustic level, temperature, and device data as well as event status and leak detection. The Steam Trap Health Monitoring software offers cost-effective installation, provides easy integration with host systems and data historians and allows enhanced insight into steam trap conditions, energy usage and emissions.

Leaking steam valves increase personnel safety risks, energy usage and your carbon footprint.

In most any steam system, you can find steam leaking through the stem packing of gate and globe isolation valves, wasting valuable heat energy and creating personnel safety risks.

Emerson's Vanessa™ was the industry's first triple offset valve (TOV). Its unique, non-rubbing design was created to provide bidirectional, zero leakage performance for positive isolation using a technology not previously available with other valves.

Vanessa TOV benefits versus gate and globe valves:

Unique non-rubbing, zero leakage triple offset design provides longer service life
Quarter turn operation eliminates any negative effects on packing, such as extrusion and stem abrasion that cause steam leaks and losses
Ease of manual operation and simpler to automate
A more compact gate/globe/ball valve replacement design that meets ANSI B16.10 face-to-face dimensions
Suitable for dead-end service
