unstable main flame of steam boiler Agent

Boiler Safety - OSHA

The flame scanner is tested with the burner firing to simulate a flame failure. A flame failure can result in a furnace explosion from the ignition of accumulated fuel in the burner. The flame scanner is removed and the scanner sensor is covered. The main fuel valve should close and the flame failure alarm sounds.

Common Steam Boiler Problems & How to Troubleshoot Repairs

Here are seven common steam boiler problems: 1. Infrequent or Irregular Maintenance. Irregular maintenance often is the heart of problems with boilers. Your boiler needs regular maintenance based on how often it's used. Not inspecting it often enough can lead to minor issues being missed, which can lead to major issues later and possibly injury.

Boiler Combustion | CleanBoiler.org

High flame temperatures and intimate air/fuel mixing are essential for low CO emissions. Some NOx control technologies used on industrial and commercial boilers reduce NOx levels by lowering flame temperatures by modifying air/fuel mixing patterns. The lower flame temperature and decreased mixing intensity can result in higher CO levels.
