"Steam System Specialist Qualification" Best Practicest Workshop -- Center Valley, Lehigh County -- January 24-26, 2006 (for more information) New Steam Technical Briefs Available Online These briefs focus on technical analysis of steam process issues, including process control schemes, heat-transfer solutions, fuel-saving heat pumps, and determining the real cost of steam. Details. Steam System Scoping Tool Now in Visual Basic DOE has just released a Visual Basic Version of the Steam Scoping Tool, in addition to the Microsoft Excel version. This scoping tool is designed to help steam system energy managers and operations personnel for large industrial plants. Updated Steam System
Scoping Tool (version 1.0d) DOE’s BestPractices
Steam program announces an updated version of its Steam System
Scoping Tool. Version1.0d assists steam operation and management
personnel in assessing steam system operations against identified
best practices. More...
New Resource: Steam System
Survey Guide Steam Best Practices - DOE Industrial Technologies Program (ITP) Over 45% of all the fuel burned by U.S. manufacturers is consumed to raise steam. Steam is used to heat raw materials and treat semi-finished products. It is also a power source for equipment, as well as for building heat and electricity generation. But steam is not free. It costs approximately $18 billion (1997 dollars) annually to feed the boilers generating the steam. More... Many manufacturing facilities can recapture dollars by the installation of more efficient steam equipment and processes. A typical industrial facility can realize steam savings of 20% by improving their steam system. If steam system improvements were adopted industry-wide, the benefits would be $4.0 billion in fuel cost reductions and 32 million metric tons of emission reductions. Steam Generation Key components include the boiler itself, boiler controls, valves piping and meters, water treatment equipment, economizers, and de-aerators. The primary purpose of an effective steam generation system is to produce steam at the flow rates and pressures required for the system end-uses. It is important to generate the steam at the highest possible generator efficiency. It is equally important that high-quality (dry) steam be produced; transmission of wet steam to the distribution system can lead to water hammer and also to inefficiencies in the end use of the steam produced. More... Steam Distribution Key components include piping, pressure control/reduction systems, valves and flanges, distribution system insulation, steam traps, air vents, drip legs, and strainers. The distribution system should supply high-quality steam to the end use equipment at the required rate and pressure, and with the minimum heat loss. More... Steam End-Use Key components are either heat exchangers, such as unit heaters, steam coils and jackets, or direct injection systems. The primary purpose of the steam end-use system is to maximize the effective use and heat content of the steam transmitted to the end-use equipment. Other key components include piping to transmit steam through the end-use equipment and condensate out of the end-use equipment, and steam traps to drain condensate from the end-use equipment. More... Steam Recovery Key components include condensate return piping and insulation, flash tanks, and condensate pumps. An effective condensate recovery system will make the best use of steam and condensate energy after process use and will return the maximum possible percentage of the condensed steam to the boiler.
