Hand-controlled burner

Hi guys,

I am working with a boiler with automatic controls. I know semi automatic burner but I have no clue at all with "hand-controlled" burner system. I googled for hours but it seemed I cannot find the answer.

Gentlemen, please help, what is hand controlled burner?

Thanks

Um, maybe a burner that has no automatic functions whatever??? [Incidentally, are you assuming none of the female contributors to these fora would be able to provide you with an answer of any value?]

Such burners can be very dangerous, depending on the circumstances, since by implication they have no control system at all, and possibly even no safety devices such as an automatic cadmium-cell-based tripping system to shut down the burner on detection of a flame-out condition. Their safe and efficient function depends entirely upon attentive and diligent care by a plant operator.

Take as an example an old school oil burner operating on a medium to heavier fuel oil, and that as a consequence employs steam as an atomizing medium. The operating engineer performs all starting, stopping and regulating actions not only for the burner but for the entire boiler, namely placing forced and induced draft fans in service, purging the furnace of combustible gases, then reducing air flow to a suitable value for lighting off, lighting and inserting a portable ignition device such as a propane burner or, going way, WAY back, a kerosene-soaked rag on a stick or rod, establishing sufficient atomizing steam flow, starting the fuel oil pump, admitting fuel oil to the burner and observing that fuel oil ignition takes place promptly, removing the igniting device, then adjusting by hand the boiler air flow, atomizing steam flow, and oil admission and oil return valves in such a manner as to obtain the heat release rate required, whether it be to slowly bring the boiler up to operating pressure from a cold state, to control the steam pressure and/or temperature and-or steam flow of an already-operating boiler to the value or values desired, et cetera and so forth.

I suspect your best source for information about such primitive systems would be the classic Audel series books for stationary and marine engineers; other contributors may suggest other resources.

Hope this helps.
