Stationary engineers and boiler operators control stationary engines, boilers, or other mechanical equipment to provide utilities for buildings or for industrial purposes.
Stationary engineers and boiler operators typically do the following:
Most large office buildings, malls, warehouses, and other commercial facilities have extensive heating, ventilation, and air-conditioning systems that maintain comfortable temperatures all year long. Industrial plants often have additional facilities to provide electrical power, steam, or other services. Stationary engineers and boiler operators control and maintain these systems, which include boilers, air-conditioning and refrigeration equipment, turbines, generators, pumps, and compressors.
Stationary engineers and boiler operators start up, regulate, repair, and shut down equipment. They monitor meters, gauges, and computerized controls to ensure that equipment operates safely and within established limits. They use sophisticated electrical and electronic test equipment when servicing, troubleshooting, repairing, and monitoring heating, cooling, and ventilation systems.
Stationary engineers and boiler operators also regularly perform routine maintenance. They may do a complete overhaul or replace defective valves, gaskets, or bearings. In addition, stationary engineers and boiler operators lubricate moving parts, replace filters, and remove soot and corrosion that can make a boiler less efficient.
