Boiler Operator Training

NIFES offer a two-day on-site steam boiler operator’s course, specifically for boiler plant engineering staff.

NIFES have provided on-site boiler plant operators training courses for decades, the training ensures that the delegates are fully conversant with the latest documentation including the new standard BG01 – Guidance on the Safe Operation of Boilers which replaces Guidance note PM5: Automatically Controlled Steam and Hot Water Boilers.

If required, the training can also incorporate a critical review of Boiler Operating Procedures and accompanying Safety Rules and Procedures and can specifically present and discuss the general requirements for insurance inspections.

NIFES courses typically follow the structure below:

NIFES offer the service of Measured Surveys to various different levels of detail. Plans are produced in CAD software and can be issued as deliverables in a variety of formats and uploaded to CAFM systems.

Floor plans, elevations, sections and bespoke details can be produced in order to suit the needs of the project.

Analytical information such as polylines defining room areas can be added to floor plans. These plans can then be integrated into property appraisal database systems to aid estate management.

Course Aim

To raise delegates’ awareness and knowledge levels with respect to the technical principles of steam generation and the safe and efficient operation of boiler plant.

Proposed Content

The proposed content is based on NIFES standard Boiler Operations training course and would be modified to suit the plant and operating conditions at the site. Particular reference will be made to the general requirements for insurance inspections on the site boiler plant.

Course Duration

Two-day classroom based at the clients site, although this can be rearranged to suit the particular requirements.

Course Outline

  • Indirect method of calculation, i.e. by assessing dry flue gas loss, radiation and other losses. Feedwater hotwell temperature, heat recovery opportunities and insulation.

HSE and other Safety Guidance Notes

  • BG01 Guidance on Safe Operation of Boilers (and differences to PM5)
  • SAFed Guidance Notes for Hot Water Boilers (as appropriate)
  • INDG436 Safe Management of Steam and
  • Hot Water Boilers
  • PM60 Steam Boiler Blowdown Systems
