Clay Radiant Heater Fired by Bituminous Coal -- any Real-Life example?

Posted by GreenXenon on September 11, 2009, 9:00 pm

Hi:

I'm currently daydreaming about a radiant heater that is made of the
same clay used by tandoor ovens and uses ignited bituminous coal as a
source of heat. Has such a heater ever been built in the history of
mankind?

I think this radiant heater would be pretty and would smell good. I
love the smell of clay and bituminous coals.

When I think of radiant heat I think not only of the heat itself but
also the visual beauty of the part of the device emitting the thermal
radiation.

It would be even prettier if this tandoor bituminous coal radiant
heater is shaped like a pyramid.

The red hot bituminous coals emit hot volatiles that heat the clay.
The causes the clay to emit infrared radiation. Within this heater
there is just enough oxygen for the coals to glow red hot and self-
sustain this combustion. The oxygen content is insufficient to make
the coals emit flames.

Once again, the purpose of this hypothetical radiant heater is not
just warmth but also to please the eyes and nose.

Thanks

I read plans many year ago, to make some kind of heater
under a clay flower pot. Certainly not as well engineered as
what you describe.

Any relation to the ceramic "Chimnea" which are sold in home
centers?

This is first time I've read about Chimnea. I just did a search on it
and yes there are some similarities but it is still different from my
hypothetical tandoor radiant bituminous heater. For example, the
source of heat, the shape, and the material the oven is made of.
