May 04, 2009· There are twenty-two primary reasons for tube failures in a boiler, which can be classified under six major groups. They can be analyzed and corrective and preventive action can taken. Good operating and maintenance practice reduces tube failures. Tube failures during the initial operation period, the normal operation period, and after ten to fifteen years operation show different trends.
combustion of the fuel particle is recorded by a high speed camera, Phantom v310 with the recording speed up to 300 000 fps. The camera is simultaneously activated when the shield blockage is released. Particle temperature is not higher than 353 K when the biomass particle is placed into cool shield tube just before the beginning of experiment.
