Jet air stove

An air door or air curtain is a device used to prevent air or contaminants from moving from one open space to another. The most common use is a downward-facing blower fan mounted over an entrance to a building , or an opening between two spaces conditioned at different temperatures.

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) defines an air door as follows: "In its simplest application, an air curtain is a continuous broad stream of air circulated across a doorway of a conditioned space. It reduces penetration of insects and unconditioned air into a conditioned space by forcing an air stream over the entire entrance. The air stream layer moves with a velocity and angle such that any air that tries to penetrate the curtain is entrained. Air curtain effectiveness in preventing infiltration through an entrance generally ranges from 60 to 80%". [1]

The Air Movement and Control Association defines an air curtain as: "A directionally-controlled airstream, moving across the entire height and width of an opening, which reduces the infiltration or transfer of air from one side of the opening to the other and/or inhibits flying insects, dust or debris from passing through".

Changes may be made to the materials in the schematic according to personal preference or based on availability of materials. Materials for fabricating stove legs are not present because many different configurations may be acceptable. Any design may be accepted for personal preference, as long as it is able to support at least 100lbs and withstand high temperatures for this model.

The legs of the stove are usually meant to be short, as to be able to easily look into a pot or pan on top of the stove from a standing position. Any design may be accepted for personal preference, as long as it is able to support at least 100lbs and withstand high temperatures. For this stove, small lengths of C-channel were used to make a sturdy base. Weld the legs to the tank before going any further; when the tank is full it is very heavy. Another feature that may be added and/or altered on the stove are the carrying handles.

The burning chamber weldment must be positioned a few inches off of the bottom of the tank. In order to seat the burning chamber in the proper place, use some of the sand to pack a level surface 2-3in high to place the burning chamber on. After fitting the feed tube through the side of the tank and centering the burning chamber in the tank, the feed tube can be welded into place.
