Fuel consumers face a double challenge. One is economic – to get the best heating value for every fuel dollar. The other is environmental – to keep emissions low, at least within legislated limits. Fortunately, what benefits the first objective also benefits the second.

A boiler installation costing $75,000 can easily consume over $400,000 in fuel every year. Consequently, even with very economical fuel costs, a difference of just a few percentage points in boiler efficiency can translate into substantial savings. Understanding boiler operating costs is the key to maximizing investments year in and year out.

This 6 - hour course attempts to provide simple facts and energy efficiency opportunities in the areas of combustion management, makeup & feed water management, condensate return, blow-down system, waste heat recovery and steam distribution and utilization.

This course is designed for chemical engineers; chemical and process engineers; system design engineers working in power, oil and gas, chemical, and metal and mining; energy auditors; and operational and maintenance personnel.

Learning Objectives

Upon completion of this course, participants will be able to:

• Compare direct and indirect methods for evaluating boiler efficiency.
• Identify energy losses in a boiler system.
• Explain combustion analysis, including excess-air control and the air-fuel mixture.
• Describe heat-recovery systems, including economizers, preheaters, and flue-gas condensing systems.
• Distinguish between common waterside and fireside boiler problems.
• Explain boiler-water treatment approaches.
• Describe the importance of condensate recovery.
• Explain blowdown optimization and waste-heat recovery using flash tanks and heat exchangers.
• Identify opportunities to improve energy efficiency in steam distribution.
• Describe methods for improving energy efficiency in steam utilization.
• Explain automation using burner controls and oxygen-trim systems.
• Apply boiler-audit checkpoints and the associated questionnaire.

Certificate of Completion

You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 30 questions. CPD credits are not awarded until the course is completed and quiz is passed.
