Show PA Tells Stove Advantages, Drawbacks From the time of the caveman, wood burning has been a source of heat. And, although the popularity of wood for home heat has waxed and waned over the years, its currently on the upswing. High heating bills, soaring electric costs, and the lack of efficient and cost effective alternate heat sources have encouraged homeowners to look to wood burning stoves and fireplace inserts as main or supplemental sources of heat. Experts estimate that 1.5 million new fireplaces and wood burning stoves are installed or built in homes annually. This rapid increase in installations and use of wood burning units may help ease some Americans' dependence on foreign oil, but in some cities, it's also added fuel to an old problem - air pollution. Just how much wood burning contributes or will contribute to pollution is not definite. Few studies on the quantity and specific nature of residential wood burning emissions have been conducted, although several studies are now in progress. In most cities, air pollution comes from a number of different sources -cars and trucks, industries and power plants. One contributor, that has for the most part been ignored, is Individuals residential and organizations are realizing that the problem is significant. Many believe that carbon monoxide problems can be directly linked to wood burning in certain cities. One scientist put the problem in perspective when he pointed out that g stoves emit about ten wood-burnin- g. wood-burnin- "When women shop for homeowners insurance, I'm usually their last stop."

Paula R. Machlin, senior technical advisor for the Environmental Protection Agency, said, "From the data we have seen it's easy to conclude that we should be concerned and proceed cautiously in the use of wood as a fuel. It would be premature, however, to sound an alarm. We can't ignore the potential of wood as an energy source." Part of the concern in the scientific community about wood burning goes beyond the absolute quantity of one particular pollutant. Scientists are looking at the nature of the emissions and finding significant quantities of cancer causing compounds. In fact, one study estimates that 80 percent of the total national concentration mobile and natural (excluding sources) of a particular type of compound, polycyclic organic material, is from wood burning. "The technical community is not alone in its concern about wood smoke," Machlin noted. "I receive calls weekly from citizens in different areas asking whether EPA is aware of or doing anything about wood burning as an air pollution problem. I think people are noticing the increase in visible air pollutants in their neighborhoods and then wondering what effect they might have on their health and what can be done. Unfortunately, I don't have an easy answer right now." The particulates and carbon monoxide from wood smoke are simply the product of incomplete combustion of the wood. Soot and gases that are not able to burn go up the chimney. Unsightly emissions from wood burning stoves and fireplaces are generally of inhalable take to ensure greater and more efficient beat from a fireplace or stove is to insulate wall and attics and weatherize windows and doors. The out, Machlin EPA's pointed needed, more winterized a house is, the less "We need to work with state and local fuel will need to be burned, fewer air quality agencies to do more emissions will go up the chimney, and analysis of ambient air in cities where fewer dollars will be spent on fuel. wood smoke is suspected to be a A study by Monsanto Corporation serious pollutant.

The results are the same - uncontrollable emissions. Plastics should not be burned and paper CUP AND f AVE burning should be restricted. Plastics emit toxic and corrosive pollutants and provide little heat. Some materials also ."coat" chimneys, raising the danger of chimney fires. Others may damage the stove itself. Another fact to consider in burning is the type of fuel. Coal burning generally produces more emissions than wood, and different types of wood vary in the amount of emissions they give while burning. Studies have indicated that moderate moisture in wood wood is far better than kiln-dr- y "' or "green wood and that fuej such as charcoal, although expensive, burns cleaner. And, finally, for safety reasons and maximum efficiency, a clean chimney is essential. For many, the "atmosphere" provided by a fire is as important as the heat it provides.

So announced Dr. Roger Plothow, director of the office of Continuing Education and Evening School at Utah Tech, who said spring quarter classes will begin March 24 and run through the first week of June. "The spring quarter is a time when roads and weather are usually good," said Dr. Plothow. "If you don't have a job; the Evening School offers you the opportunity to further enhance your skills." Evening School classes, for regular college credit except a few specified courses, usually run one to three or four times a week. Persons holding daytime jobs, or mothers and wives with daytime responsibilites may use their leisure time at night at Utah Tech. Evening school students may register anytime between now and the start of the quarter, said Dr. Plothow, from 8 a.m. to 8 p.m., Mondays through Thursdays and 8 a.m. to 3:30 p.m., Fridays, at the Evening School headquarters on the and welding, with , non-cred- it 7 6:00-9:0- 5:00-7:0- QBGDILILIieil 5:00-7:0- at provo 1395 NORTH 150 EAST, PROVO, UT PHONE P.O.
