Jul 15, 2006 · My oil fired boiler is smoking. If the baffles are blocked, then the burner will only take in as much air as it can exhaust, but will still put in the metered amount of oil, hence the smoke. If the combustion has been rich for a while, then you only notice the smoke when the boiler blocks with soot.
Aug 22, 2018 · The fire tubes are immersed in water inside the main vessel of the boiler. As the hot gases are passed through these tubes, the heat energy of the gasses is transferred to the water surrounds them. As a result steam is generated in the water and naturally comes up and is stored upon the water in the same vessel of fire tube boiler.
Puff, Puff. Improper burning is the cause of black smoke coming from a boiler. If the oil does not burn normally, it will produce a dark-colored smoke that may be seen from the rooftop vent or wafting directly out of the boiler. Improper burning can have several causes including an improper mixture of air and oil, blocked fuel nozzles,
3.Two types of high pressure water tube boilers are specified, flex tube and D-type.
