Detroit, I'd look for a stoker and put a squirrel cage blower on the furnace(s) to get decent efficiency. A bituminous coal stoker will allow you to burn inexpensive bituminous stoker coal (~100/ton)
That sounds like good advice. What is a squirrel cage blower? And is a stoker a device that feeds coal into the furnace automatically per temperature or time?
Can I hook those up myself? What about grates for the furnaces?
Do I need to post pictures of the furnaces?
Do you, or anyone else here have a picture of an Octopus furnace with a squirrel cage blower and a bottom stoker attached.
I'd like to see the construction. I'm not sure what the squirrel cage is doing: is it intended to pull the smoke out of the furnace?
