Feedback on THE SAWDUST STOVE

There's really no way to determine the degree of incomplete combustion—and corresponding danger—in a stove such as the one described in the article. The device must certainly be used with adequate ventilation, as the author stated, but this might make it ineffective as a heat source. At any rate, it would seem inadvisable to use the non-vented heater in a sickroom or other area in which the occupants are sleeping or incapacitated (I'm thinking especially of babies and elderly persons). If combustion were poor, one average night's rest could turn into an eternity.

The larger models of the stove appear safer, since a flue would likely be used to vent any fumes. Nevertheless, anyone who uses either this or the smaller heater for long periods should immediately seek fresh air—preferably outdoors—if headache or dizziness develops.

In case you're wondering, I'm by no means an expert on combustion. As a chemical engineer now working for a government agency on air pollution control, however, I'm often concerned with incineration and with the use of wood waste as fuel . . . and I must emphasize one point: Although various efforts have been made to control air pollution from the burning of wood by controlling the combustion process, such operations have proven very tricky. With many types of combustion devices it's possible to reduce the amount of smoke produced, but not the amount of carbon monoxide. Deaths from poisoning by this deadly gas have resulted in the past from the use of charcoal as an indoor fuel . . . and the principle of the sawdust stove is very similar. I offer these comments in the hope of preventing MOTHER's readers from injuring themselves.

Although I have my doubts about the sawdust stove in the form described, I thank B. R. Saubolle for sharing his knowledge.

    I tried this out today in the garden and was very impressed by how well this works and how efficient it is. I then enclosed the burner by putting the paint tin lid on with a metal pipe going through acting as a chimney.

    Could you use the sawdust burner inside a woodstove with the
    dampers wide open? Phil
