KILN THERMOCOUPLES. The Basics. A thermocouple is a heat-measuring sensor composed of two dissimilar metals joined at one end. When the joined end is heated or cooled, it creates a temperature gradient along the length of the thermocouple. That gradient will create a predictable voltage correlated to the temperature of the joined end.
the vertical shaft kiln. This kiln can be described as an upright heavy steel cylinder lined with refractory material. The limestone is charged at the top and is calcined as it descends slowly to discharge at the bottom of the kiln. A primary advantage of vertical kilns over rotary kilns is the higher fuel efficiency. The primary disadvantages of
