The pioneer car tunnel kiln for the firing of roofing tile is described. The kiln is 324 feet, 11 1/2 inches long and holds 52 cars each of which carries 2.3 tons of fired ware. Ten furnaces equipped with Maxon Premix combination oil and gas burners arc used. A schedule of one car every 65 minutes is in operation, 56 hours and 20 minutes being required for a trip through the kiln. The ware reaches a maximum temperature of 1820°F and is drawn from the kiln at 400°F. Additional cooling is accomplished with a portable fan. The kiln has a capacity equal to ten 30‐foot round down‐draft kilns and shows a fuel saving over the latter of 64.2%. A total of 15 h. p. is required. A saving in setting and drawing labor of 29.2% and 45.8% respectively is effected.
