Title: Coal in an E-Classic 1400?
Post by: Roger2561 on November 13, 2011, 01:19:26 PM: Hello again,

The simple question is, can one safely burn coal in an E-Classic 1400 to augment the wood supply? If I can make my wood supply last longer into the season I'd probably consider it, but I need to know if it's safe for me the operator and the OWB. I'd like to hear your thoughts and concerns.

Thanks so much.

Roger

Some have said the coal burns longer than the wood when the damper is closed and may cause a boilover. I would say in smaller amounts it wouldn't hurt. Probably have to experiment a little bit. Wish I had access to some here in Michigan, I'd love to try it.

Hi Scott7m,

Please elaborate as to why you wouldn't put coal in a gassifier? This is for my benefit as well as for those who may be contemplating the same thing.

Thanks,

Roger

Also gassifiers simply aren't designed for coal, just seasoned wood. Coal needs air coming in from below the fire to give a good burn, that's why coal units have shaker grates and a way to get air under the coal.

Another reason is th fan and secondary burn chamber is designed to be able to burn a certain % of wood gas and if this balance is disrupted I'm not sure what the results would be.

Post by: MattyNH on November 14, 2011, 07:48:55 PM: Ive notice that theres been a lot of coal posts lately.. And how much cheaper that coal is than wood.. They do make OWB's that are designed to just burn coal..Not sure after spending 10K on a E- Classic Id be throwing coal in it.. Might void warranty...I get the point of making the "burn" last longer ....If coal is cheaper.. Why not buy a coal OWB?

Thanks for you input. Generally not a good idea. I'll stick with wood. It'll be safer for me and the OWB plus I don't want to void the warranty.

Enjoy the warm weather here in NH. Another day of temps hitting the 60's. Very unusual if you ask me, but I'm not complaining.

Have a great week.

Roger

Why don't you call CB and ask them? They should be able to answer your question.

There answer would be because it voids the warranty. Says right on it wood fuel only
