Furnace Temperature Element Temperature And Surface Load For the suspended element types the element surface load in most cases cannot be defined. in addition to the surface load, ambient temperature, heating dissipating conditions and presence and location of other elements will influence the wire temperature and therefore also the choice of wire surface load and element surface load. surface load. The temperature referred to is actual element operating temperature. it is based on the inter relationship of furnace temperature, element watt loading, and the ability of the element to radiate the heat generated. design information is available from a variety of sources showing the effects of element placement on radiation ability and the.
