What is a solar furnace?
Solar furnace is a structure used to dry and treat solar energy. Solar furnaces can be used by people like woodcatters and fans, as well as wood processing equipment. Depending on the position, season and the amount of timber, it may take less than a month to almost two months before the timber is completed in a solar furnace. It has a very high moisture content and is swollen with liquids. Green wood can be processed into lumber, but cannot be used immediately. If green lumber is used in construction, it tends to deform and distortion as it dries. As a result, the timber must be cured before use. One option is to have it stacked outside, but it may take a long time because the ambient moisture captures the moisture inside the lumber. The solution is a furnace, a heated environment that quickly and evenly dries the lumber.energy and requires a power source. The solar furnace relies on solar energy to warm the air fans and power to draw hot air over the lumber to dry it. SolarThe furnaces can also be mobile, allowing wood processing anywhere and usually building very cheap. This can be important for people who want to process their own lumber for budget.
Solar furnaces are designed a lot like a greenhouse. The sloping roof is tilted to use sunlight, and fans are used to maintain air circulation in an oven. Fans for the upper air attraction to the hottest part of the sunflower, while the fans at the bottom pull out the heated air through the curing timber and vent it as soon as the humidity is loaded. Fans can be powered by a photovoltaic panel.
The initial investment needed to create a solar furnace depends on the size and building materials. Once built, the furnace is free to operate, although regular expenses may be required to perform tasks such as replacement of broken panels on the roof. After cure, the timber can be stored nobo use immediately.
Several innovative people have explored the idea of building a solar furnace for ceramics. Shooting of ceramics requires temperatures much warmer than temperatures achieved in a wood furnace. Most solar pottery furnaces use a parabolic reflector that lags the heat on a very small chamber. The chamber is small enough that it can heat up sufficiently, but usually cannot hold more than one or two items for firing, so the furnace is somewhat ineffective.
