Burners may rot or get blocked jets but don't generally "fail" so if it's

It will light, but blue flames immediately appear around the front of the boiler casing.


That sounds, um, a bit f*cked. ;-)

You really need to take a look at the burner to see what's what and if it's
repairable. As John says, a replacement burner is probably unobtainable.
