Thanks for the responses to my last question they were extremely helpful.
Here is my next problem. The soda kiln is going to be located in the
basement of an art center in the same room with five other kilns. one gas
and four electric. all of the kilns currently have enter-connected hood
vents powered by a single unit. in addition the gas kiln has a pipe leaving
its chimney that inters the wall and connects with a preexisting chimney
from an old fire place. The building is surrounded by public property and is
considered an historical monument which means the exterior appearance of the
cannot be altered. I'm wondering what the options are for venting a soda
kiln. is a hood vent in addition to a pipe out the chimney adequate. or are
the fumes released heavier than air so that it would require a floor vent of
some kind too. Is it OK for the ventilation system of a soda kiln to be
incorporated into that of other kilns or does it need its own? If it does
need its own how powerful does it need to be? Also, there currently no doors
on the kiln room, would you recommend putting some on? (the building is
pressurized so this may effect the firing of the kilns) Any advice you might
have would be great. Thanks Dana Shearin

Dear Dana Shearin,=20

Whatever system you use to ventilate your Soda Kiln remember; firstly =
that much of what is vented will be particulate material and will build =
up at bends in the system if the exhaust velocity is not high enough; =
secondly that if Carbon Dioxide escapes into the room it will settle =
because of its density in relation to that of air. In a basement it will =
remain as a stagnant pond of deadly gas. Eliminates vermin but could be =
death of the faculty cat.
