WebIn the direct resistance heating, the electric current passes through the charge itself. This current produces I 2 R losses in the form of heat within the body itself. This principle is used in heating water by means of an electrode boiler. In the case of the electrode boiler, the electrodes are lowered into the tank filled with water. WebDirect-fired-type. This is the simplest form of heat application. As the name implies, fuel is fired into the furnace without any form of baffle. The burners may be located on the sides, ends, or sometimes the roof of the furnace. The flue gases are removed through flues in the roof, sidewalls or hearth (Figure 6d ).
