[...]... than in a boiler furnace Since carbon is the major element in fuel, we make lots of carbon dioxide in a boiler Next in quantity is water Now, that brings up an interesting point, if we’re making carbon dioxide and water, both common substances that we consume, then what’s the problem with boilers and the environment? We’ll get to that but, Boiler Operator’s Handbook for the most part, firing a boiler. .. power and don’t have to be so big ELECTRICITY If there’s anything that boiler operators pretend to know nothing about it’s electricity I have met several boiler operators that would send for an electrician to change a light bulb To choose to know nothing about it is to doom yourself to becoming a janitor, with pay to Boiler Operator’s Handbook match Not only are we in an age where electricity powers our... know them ASME Boiler and Pressure Vessel Codes (BPVC): Section I – Rules for construction of Power Boilersa Section IV – Rules for construction of Heating Boilersa Section VI – Recommended Rules for Care and Operation of Heating Boilersb Section VII – Recommended Rules for Care and Operation of Power Boilersb Section VIII – Pressure Vessels, Divisions 1 and 2c (rules for construction of pressure vessels...

Changes in the scope of a boiler plant operator’s activities make maintaining that order important Modern controls and computers that are used to form things like building automation systems have relieved boiler plant operators of some of the more mundane activities We have taken huge strides from shoveling coal into the furnace to what is almost a white collar job today As a result, operators find themselves... steam pressure or with hot water below 250°F don’t need boiler operators present The justification is elimi- 25 nating the high wages of boiler operators There’s the main source of the false economy Installing many more boilers to maintain will reduce the cost of qualified operators Ha!
