Woodstoves fireplace

Unvented kerosene and gas space heaters leaking chimneys and furnaces back-drafting from furnaces, gas water heaters, woodstoves, and fireplaces automobile exhaust from attached garages environmental tobacco smoke. Humans are normally the main indoor source of carbon dioxide. Unvented or imperfectly vented combustion appliances can also increase indoor COj concentrations. 

If you like, you can collect potassium carbonate the old way by leaching it from wood ashes (especially oak wood, grape vine, and fern ash.) This will give you something to do with all those ashes you clean out of your fireplace or woodstove. Just scoop them out and place them into a large plastic bucket. Pour clean water over them (tap water is fine) stir and let settle. Pour off the clear liquid from the top, filter and evaporate the water. Be careful, because it is quite caustic and can bum the skin and seriously injure your eyes. It is like lye (in fact it is lye) and they used to make soap this way. 

Long and Weaver (1985). The efficiency does not include a correction for moisture content. When adjustments are made for moisture, the efficiency of the average airtight woodstove or fireplace for wood fuel with 20% moisture, for example, would be 50% rather than 63%, or 10% rather than 13%. 

EXPOSURE ROUTES Inhalation (present in natural environment as a product of plant respiration, incomplete wood combustion in fireplaces and woodstoves, coffee roasting, burning of tobacco, vehicle exhaust fumes, coal refining and waste processing) absorption.

When a propane heater, fireplace, or woodstove is used in a closed room, there must be adequate ventilation. If the supply of oxygen is limited, incomplete combustion from burning gas, oil, or wood produces carbon monoxide. The incomplete combustion of methane in natural gas is written...
