[Stoves] In praise of kerosene

[Paul Olivier]

AJH,

I tried many times to light rice hulls with kerosene.
This does not work very well in conjunction with updrafting air.
The kerosene fumes generated in this lighting process stink quite a bit.

I also tried to light rice hulls with a gas-jet flame.
This does not work at all.

So I tried cardboard.
When cardboard burns above the rice hulls, it initially emits a lot of
smoke.
After a while, it turns to a sort of charcoal and emits radiant energy.
As soon as the cardboard turns red, the rice hulls ignite.
When the rice hulls ignite and burn, they emit no visible smoke.

All of the smoke in the lighting of the gasifier comes from that initial
burning of cardboard.
So if we had a device that only generated radiant energy, this should be
ideal for lighting rice hulls.

The same logic applies to pelleted rice hulls.
They light easily as soon as the cardboard turns red.
I assume that the same logic would apply to pellets made from other types
of biomass.
Perhaps this assumption is wrong.


Thanks.
Paul
