Boiler Operations & Boiler Maintenance | O&M | BetterBricks
Although boilers have many different specific ignition systems, they all follow the same basic sequence of steps: 1. Pre-purge of the furnace. 2. Reduction of air flow for stable ignition. 3. Pilot burner ignition 4. Main burner ignition. Small boilers often have completely automatic ignition systems. Some older, or
Burner Start Procedure ..18 Initial Air Settings at least the minimum pressure required to the burner gas train inlet at the burner's full capacity rating. Refer to Table 1. Boiler Manufacturer and Model, When Applicable Additional Codes. CG15, CG25,
The specific boiler/burner manual provides the details on what type of transitions are required, and these must be followed to prevent combustion noise and vibrations. The ABMA publication "Packaged Boiler Engineering Manual " offers a helpful general overview for typical Firetube boilers and other large commercial and industrial products.
Most boilers use natural gas, fuel oil, or coal burners to provide heat to the boiler. The key components of natural gas burners include pilots, impellers, spuds, spiders, and igniters. Knockout pots remove liquids and condensate from the fuel gas before it is sent to the burners. Damp-ers regulate the flow of air to the burner. Impellers in boilers are not the same as impellers in turbines or pumps.
Confirm proper location and orientation of burner diffuser spuds, gas canes, etc. Look for any burned-off or missing burner parts, and replace as needed. b. Check for Clean Boiler, Steam Generator, or Process Heater Tubes and Heat transfer Surfaces. External and internal build-up of sediment and scale of the
