Keith Company Coiled Resistance Wire Wound Elements

Keith Company manufactures wire wound (aka coil resistance wire) heating elements that work best for air velocities of 5 to 2,000 SFPM. Higher air velocities could cause the coils to touch each other and short out, so tubular air heaters may have to be considered.

Keith Company Electric Heating Elements for Furnaces

Since an electric heating element transfers heat by convection and radiation to the interior of the furnace and to the load, the element surface temperature is always higher than the furnace/process temperature during the heat-up and soaks portions of the firing curve.

I. Determination of the heating element parameters

Design medium-temperature resistance heating elements in the form of a spiral (Fig.1) for a 3-phase resistance furnace of a given power P (value of power given individually to each student). The furnace is supplied from a 3-phase 230/400 V line. The heating elements should be made of a Kanthal A-1 round wire. Assume the temperature of the heating element equal to 1200 °C.

How to Test a Heating Element6 Steps (with Pictures

Aug 09, 2019 · Measure the resistance by disconnecting the heating element from any power source, and connecting the multimeter leads to the terminals of the heating element. If the reading is the same or very close to that of the calculated value, then the element is OK and the fault lies elsewhere.

Thus, a current of one ampere flowing through a wire with one ohm resistance would heat this wire at a rate of one watt. Because the current is squared in the equation, two amperes through the same wire would heat it at a rate of 4 watts, and so on.

But then I realized that when resistance of the heating element is too low, power drawn will be too high and can cause excessive heating on the element. So, the resistance is chosen as low as possible to produce more heat, but with caution to the risk of damage to the element if the power drawn is too much that can’t be withstood by the element.

Resistance Furnace Article about Resistance Furnace by

Most resistance furnaces are of the indirect type. In indirect-heat resistance furnaces, electric energy is converted into heat when a current flows through the heating elements. The heat is transmitted to the articles to be heated by radiation, convection, or conduction.

1. Resistance Heating Alloys NiFe Up to 600 °C 1110 °FNIFETHAL 70 and 52 are alloys with low resistivity and high temperature coefficient of resistance. The positive temperature coefficient allows heating elements to reduce power as temperature increases. Typical applications are in low temperature tubular elements with self regulating features.

resistors - Resistance of a heating element - Electrical

A heating element has neither "very high" nor "very low" resistance. The total energy dissipated by the circuit is proportional to current, so the resistance of the heating element has to be low enough to draw sufficient current to generate enough heat.
