Oil burners and oil stove safety in 3 points

   It is ideal not to operate any oil stoves because:

1.They never burn with a clean blue flame, they smoke, clog up, have very low efficiency, up to twice as low, and are not environmentally friendly.

2. When burning in heaters and stoves, toxic substances escape exactly according to the color of the flame - dioxins, fluorines, and sulphites, which only burn at temperatures of 2000 degrees Celsius and above on an atomic level.

3.Often, stoves and heaters heat up to the point where only radiant heat is capable (especially in an auto repair shop) of igniting flammable materials such as oil-soaked rags, degreasers, plastics. They are capable of igniting soot in the chimney, which they eagerly produce, and then it becomes a super problem as soot can burn as very good and heat-generating fuel - pure carbon with access to air and temperatures over 1000 degrees Celsius. Older chimneys without stainless steel liners can crack, then exhaust gases can leak into living spaces and poison family members! You really don't want that. Furthermore, there must be a minimum of 3 meters of absolutely clean space around such stoves and heaters without any flammable material.

Regarding oil burners:

1.Ideally, the burner should be located in a boiler, preferably gas-fired, which is dimensioned for such purposes; any stationary gas boiler is sufficient (they old are practically free nowadays, or very cheap), or even better, completely enclosed in a boiler intended for oil. (These are expensive, as are the burners for them, and not everyone can convert them to used oil). In both cases, so that no emissions can escape from the boiler.

2.The burner must be of auto-stabilizing construction, meaning that in the event of a micro-explosion from water ingress into the burner and flame extinction, the operation must spontaneously return to its original state - the flames must reignite spontaneously, immediately!

3.The burner must be equipped with a fan with an anti-flashback flame flap and must have reliable protection against oil overflow, such as a valve, float switch, electro-valve, and reliable protection in the event of a power failure from a UPS and the like.

I know from discussions that many of you do not have this, I can only appeal to your caution and advise appropriately. I can't do more...

       Perhaps I can point out the current trend, where many wise used oil burners are moving away from stoves and oil heaters in favor of oil burners located in central heating boilers. They then have much greater system efficiency. The wiser ones then sell their creations of stoves and heaters, which burn incompletely and with low efficiency.

       I also see a lot of burners being sold for boilers that are poorly designed at first glance (especially those low and square ones - simply from the logic of vortex flow, it cannot work), so they burn yellow-blue at best, but that also clogs up boilers and does not have the correct efficiency, not to mention that they get clogged completely within 4 hours of operation and then burn yellow-orange, and then you have the same problem as with stoves and heaters - clogging up of heat exchangers and flue paths.

       I wish you all the best of luck, dear lovers of oil flames! May it burn as efficiently as possible for you, i.e., as cheaply as possible, and may nothing smoke come out of your chimney no matter what you have...
