Review your blowdown practices to identify energy saving opportunities. Examine operating
practices for boiler feedwater and blowdown rates developed by the American Society of
Mechanical Engineers (ASME). Considerations include operating pressure, steam purity, and
deposition control. Consider an automatic blowdown control system (see sidebar).

The Office of Industrial Technologies (OIT), through partnerships with industry,
government, and non-governmental organizations, develops and delivers advanced
energy efficiency, renewable energy, and pollution prevention technologies for
industrial applications. OIT is part of the U.S. Department of Energy's Office of
Energy Efficiency and Renewable Energy.
OIT encourages industry-wide efforts to boost resource productivity through a
strategy called Industries of the Future (IOF). IOF focuses on the following nine
energy- and resource-intensive industries:
" Forest Products
" Metal Casting
OIT and its BestPractices program offer a wide variety of resources to industrial
partners that cover motor, steam, compressed air, and process heating systems.
For example, BestPractices software can help you decide whether to replace or
rewind motors (MotorMaster+), assess the efficiency of pumping systems (PSAT),
or determine optimal insulation thickness for pipes and pressure vessels (3E Plus).
Training is available to help you or your staff learn how to use these software
programs and learn more about industrial systems. Workshops are held around the
country on topics such as "Capturing the Value of Steam Efficiency," "Fundamentals
and Advanced Management of Compressed Air Systems," and "Motor System
Management." Available technical publications range from case studies and tip
sheets to sourcebooks and market assessments. The Energy Matters newsletter, for
example, provides timely articles and information on comprehensive energy systems
for industry. You can access these resources and more by visiting the BestPractices
Web site at www.oit.doe.gov/bestpractices or by contacting the OIT Clearinghouse at
800-862-2086 or via email at firstname.lastname@example.org.
BestPractices is part of the Office of
Industrial Technologies' (OIT's) Industries
of the Future strategy, which helps the
country's most energy-intensive
industries improve their competitiveness.
BestPractices brings together the best-
available and emerging technologies
and practices to help companies begin
improving energy efficiency, environmental
performance, and productivity right now.
BestPractices focuses on plant systems,
where significant efficiency improvements
and savings can be achieved. Industry
gains easy access to near-term and
long-term solutions for improving the
performance of motor, steam, compressed
air, and process heating systems. In
addition, the Industrial Assessment Centers
provide comprehensive industrial energy
evaluations to small and medium-size
