Error Correction: (4:29) The part that states, "Boiler water inevitably becomes acidic over time" is incorrect and has been corrected as follows. Boiler water is least corrosive when slightly alkaline. Therefore, the water is initially supplied to the boiler in a slightly alkaline state. If the boiler is operated continuously, the water will circulate and gradually increase in alkalinity. This will gradually increase the risk of alkaline corrosion. To prevent this, a slightly acidic cleaning agent is injected periodically. However, if the operator is careless and over-injects the cleaning agent, the water will gradually become acidic. In other words, it doesn't always become acidic; it will either become alkaline or acidic depending on the boiler's maintenance. ^^ This lecture covers common theory for the Energy Management Technician/Industrial Engineer/Master Technician written exams. For the Industrial Engineer exam, combustion calculations, thermodynamics, furnaces, and refractories are added after the common theory, and the questions in the past exams differ. The Master Technician exam includes an industrial management subject added after the common theory section, and there are differences in the previous exam questions.
