BOILER PLANT OPERATOR POSITION DUTIES ‐ ABERDEEN Proving Ground, MD: Plant operators start, operate, adjust, stop, maintain, and perform various operational repairs on single or multiple fuel 500 or more horsepower boilers to include a cogenerating heat and power turbine and associated auxiliary and pollution control equipment. Boilers use oil and gas to produce steam or high temperature water required for heating operations. Boilers operated require constant attention to maintain efficiency and control the formation of pollutants. Operators maintain efficient combustion levels and ensure compliance with air pollution laws or regulations. Through the use of manual, automatic, or microprocessor controls or control systems, boiler plant operators monitor, adjust, and control all phases of boiler plant operations. Incumbent use electronic, hydraulic, and pneumatic controls, and zone charts in conjunction with meters, gauges, and computer‐generated date to determine adjustments or corrections necessary for proper boiler operations or changing load requirements. They operate, adjust, and maintain auxiliary and pollution control equipment such as electrical or steam driven pumps. Forced and induced draft fans, air compressors, deaerating equipment, feed water heaters, economizers, fuel heaters and delivery equipment, and demineralizing systems. They adjust fuel feeds and the volume and velocity of draft and other fire box variables to achieve maximum combustion efficiency with changing load demands or variations in fuel quality. They regularly observe and note readings on gauges, meters, detectors, recorders, boiler water level indicators, and computer generated and analog displays to detect danger signals in operations. They analyze test feedwater, boiler water, and condensate using standard chemical tests. The operator determines the treatment and chemicals to be used to control chemical concentrations, remove impurities and entrapped gases, or stabilize fluctuating water conditions in the boiler. In some work situations, due to operating pressures or user requirements, they are required to maintain low water cutouts, high pressure cutouts, and purge type combustion safeties.
They perform operational maintenance (e.g., lubricate equipment and power clean water tubes) and repairs of limited to moderate complexity (e.g., replace or repair valves, Gauges, and pumps) on mechanical parts and systems and may be required to perform limited or basic electrical repairs. They may operate emergency electrical generators to meet plant electrical requirements when the main electrical source is unable to provide the necessary power. During the non‐ heating season, the incumbent will be responsible for performing preventative maintenance to heating, ventilation, air conditioning and refrigeration equipment. 55%
