Boiler Services

Boiler services repair, rebuild, maintain, and install industrial boilers. They may also provide cleaning, calibration, condition assessment, field inspection, failure analysis, and part replacement services. Boiler services may service many different types of boilers, or specialize in one of more specific types. Common boiler types include fire tube or Scotch marine boilers, water tube boilers, cast iron boilers, steel boilers, copper-finned boilers, composite or hybrid boilers, firebox boilers, steam generator boilers, radiant boilers, and fluidized bed boilers. Applications for boiler services are categorized as light industrial, heavy industrial, marine, residential, hospital, and commercial.

Many boiler services perform boiler repairs and boiler rebuilds. Boiler repair services may specialize in the repair of boiler casings, drums and headers, soot blowers, ductwork and breeching, expansion joints, de-aerators, feedwater systems, and other boiler components. Boiler repair services may also perform pipe fabrication and installation, re-studding and welding, and tank erection operations. Some boiler repair services hold an NBIC R-stamp, a national board inspection code (NBIC) designation for both workmanship and materials. Boiler rebuild services are also commonly available. These boiler services may rebuild large-scale industrial boilers by replacing components such as tubes, pre-heaters, and refractory materials.

Boiler services provide boiler maintenance services, boiler installation services, and boiler cleaning services. Boiler maintenance services perform preventive maintenance (PM) activities in order to maximize boiler efficiency and prevent boiler failure. Boiler installation services may install new equipment or upgrade existing equipment. Often, they can advise clients about factors such as pipe sizing, flow calculations, and structural analysis. Boiler cleaning services use high-pressure water jet equipment to remove ash and slag from consumed fossil fuels. These boiler services clean boiler areas such as air pre-heaters, fire box walls, heat and reheat pendants, hoppers, and screen tubes.

Types of boiler services include boiler calibration services, boiler condition assessment services, boiler inspection services, and boiler failure analysis services. Some companies also provide boiler replacement parts. Typically, boiler maintenance activities consist of changing the boiler water sight glass and checking the air level in the boiler room. Boiler technicians who work for these boiler services also check the bleeder valves, burner flame output, carbon monoxide spill switch, circulator pump, circulator pump flanges, and drain-out valves. Boiler maintenance checks may also include inspection of the emergency switch, flu damper, flue pipe, pilot light, return line, switch relays, and nozzles.
