I am restoring a 5" Duchess the boiler of which is in generally good condition.
However the flue tubes, which are about 15/16 ins. I.D., are coated internally
with a layer of hard, black carbon. I have given it the usual flue brush
treatment which produced clouds of black dust but a hard layer about 1/64 ins.
thick remains.
I have tried fitting the flue brush into an electric drill and giving the tubes
a few minutes of rotary action to little effect. I am wary about trying
anything more aggressive as I have heard quotes of over £2000 for a replacement
boiler.
Any ideas anyone?
