There are plenty of pressure jet boilers that run on 35 sec / gas oil, this is what the bog standard domestic boiler used to be and still are. Drip feed were usually 28sec oil /paraffin/kerosene. The difference between the two systems was that 28sec oil would ignite with a hot wire coil and could be gravity fed /drip feed to the boiler.
In the case of 35sec oil this system would not work as the diesel would not ignite easily,it had to be pumped through a minute jet atomising the fuel and then ignited with an electrical spark, hence the name pressure jet.
Now before you all jump on me and say my stove is gas oil gravity fed and that works, this is true, the two systems described previously are for automatic start up, in the case of drip feed diesel stove these have to be started manually.
The principle of the ignition is different, with a drip feed diesel stove the burner chamber has to be pre-heated, usually with a firelighter, this then heats the base of the burner pot so when you turn the knob on the fuel regulator to start the flow and the diesel arrives at the burner pot, as it dribbles in it is vaporised by the heat in the metal on the base of the burner pot.This vapour is ignited by the remnants of the flame from the firelighter. The difference being here you are igniting a fuel vapour as opposed to igniting an atomised fuel.
A correct burn is when the fuel ignites about 12mm above the burner pot base. with what looks like empty space between but is actually rising vaporised fuel.This is why if you overdo the fuel flow and turn it up too much you can actually cool the burner pot with diesel and the burn rather than being vapour will become diesel boiling and sounding something like a hot chip pan, which is exactly how chip pan fires start - the hot oil boils over and ignites, this then fires the vapour and as it's in free air the cycle just continues.
I used to short cut the start up of my stove by heating the burner pot base to red hot with a turbo gas torch. Start up time 2 minutes as opposed to 10. Just keep your face away from the hole when you start up as the fuel will vapourise very quickly and on ignition will blow up through the lighting port.
