In Reply to: Re: Proper air/fuel requirments in a wood fired boiler posted by Chris Berger on November 04, 2004 at 12:50:51:
: I run the boilers and kilns at our facility and the wood waste is clean, no garbage, chemicals or oils.
: We manufacture baseboard and casing moulding so we dry the wood down to 7%.
: Stack temp runs between 300F and 400F.
: The firebox consists of stationary grates with overfire and underfire fans. There is an ID fan in the stack. The fans are all controlled by a computer, we just do not have good air/fuel curves.
: We have done an ash fusion test and found the softening temp. to be 2150F in a Reducing atmosphere and 2240F in a Oxidizing atmosphere (not sure the differance)
: Thanks for your help.
: Chris
