Oil Ignitors In a CE Tangential (Corner) Coal Fired Utility Boiler?
Oil Ignitors In a CE Tangential (Corner) Coal Fired Utility Boiler?
(OP)
Does anyone here have any expertise or know someone on here that might have some expertise in designing of ignitors for a tangential fired boiler that has the HORN TYPE SETUP that uses the slit between the boiler tubes as the entry for the oil ignitor and its combustion air?
Looking at thoughts of how the air and coal coming in at 90 degrees to the ignitor flame would effect it... if the flame was not kept starting back in the horn- would it be extinguished?
I also wonder if anyone knows if a combustion air velocity for an oil ignitor of 70-80ft/sec (a little over 50mph) would have any negative effects on a flame.... remember the shape of the area of the air flow is that slit (about 1.5"x16" or so) between the boiler tubes...
Thanks a lot.
