over 1 year and have gone through all of the trial and error of this type of coal burning.I burn the same coal

as Berlin,and Pittsburgh seam,and use a under burner coal boiler which has under fire air and an adjustable

secondary air for burning the volatiles in the initial startup of combustion.It is a trial and error process to get this setting

right for a smoke free burn and high efficiency from the many different types of Bituminous coal.

If I burn a Pittsburgh coal which is much more dense I have to almost keep the secondary air

closed like the hard coal burners,it also needs a much higher draft about .o8 to get a clean burn, it likes

a lot of heated under the fire air to burn with a hot and clean flame.The Pittsburgh coal is of very high

quality and never forms any clinkers just white/gray ash of about 8% , the Puxy coal from Valier also has

similar ash and also no clinker.Clinker is from a high ash and lower quality coal not the Western PA coals.

These coals have near 14000 btu/# even more than anthracite.

I keep my boiler at 170/180* and when the air flow is off the chimney is at 100/120* and I can hold my hand

on the pipe one foot above the flue outlet of the boiler.
