ELECTRICAL HEATING METHODS - ramani144 - 08-16-2017 Submitted by: - SHASHI KUMAR .K [attachment=7513] INTRODUCTION Electrical heating is based on the principle of that when electric current passes through a medium heat is produced. Let us take the case of solid material which as resistance R ohms and current flowing through it is I amps for t seconds than heat produced in the material will be H=I Rt Joules. DOMESTIC APPLICATIONOF ELECTRICAL HEATING Room heater for heating the building Immersion heater for water heating Hot plates for cooking Geysers Electric kettles Electric Iron Electric oven for baking products Electric toasters INDUSTRIAL APPLICATION Melting of metals Electric welding Mould ling of glass for making glass appliances Baking of insulator Mould ling of plastic components Heat treatment of pointed surpasses Making of plywood. CLASSIFICATION OF ELECTRICAL HEATING Power Frequency heating Resistance heating Direct Resistance heating Induction heating Indirect Resistance heating induction heating Arc heating Direct Arc heating Indirect Arc heating High Frequency heating 1. Induction heating a. Direct Core type b. Core less type 2. Dielectric heating RESISTANCE HEATING This method is based upon the I R loss. Whenever current is passed through a resistor material heat is produced because of I R losses. 1. DIREDCT RESISTANCE HEATING 2. INDIRECT RESISTANCE HEATING CAUSES OF FAILURE OF HEATING ELEMENTS Formation of hot spots. Oxidation Corrosion Mechanical failure DIELECTRIC HEATING APPLICATION OF DIELECTRIC HEATING Plywood Industry Sand Core Baking Plastic Industry Tobacco Industry Bakeries Electronic Sawing Dehydration of food Electro medical application Book Binding ADVANTAGES OF ELECTRICAL HEATING OVER OTHER METHOD OF HEATING Clean and atmosphere No pollution Controlled temperature Localized application Uniform heating Highest efficiency of utilization Cheap furnaces Mobility of job ELECTRICAL HEATING METHODS - ShockWave17 - 08-16-2017 Submitted by: - SHASHI KUMAR .K [attachment=7547] INTRODUCTION Electrical heating is based on the principle of that when electric current passes through a medium heat is produced.
