To make the students conversant with boiler feed water requirements, related
water treatment techniques.
Principles of electrochemical reactions, redox reactions in corrosiion of materials
for corrosion prevention and protection of materials.
Principles and generation of energy in batteries, nuclear reactors, solar cells, wind
mills and fuel cells.
Preparation, properties and applications of engineering materials.
Types of fuels, calorific value calculations, manufacture of solid, liquid and
Introduction to boiler feed water-requirements-formation of deposits in steam boilers and
heat exchangers- disadvantages (wastage of fuels, decrease in efficiency, boiler
explosion) prevention of scale formation -softening of hard water -external treatment
zeolite and demineralization- internal treatment- boiler compounds (phosphate, calgon,
carbonate, colloidal) - caustic embrittlement-boiler corrosion-priming and foamingdesalination of brackish water –reverse osmosis.
ELECTROCHEMISTRY AND CORROSION
Electrochemical cell - redox reaction, electrode potential- origin of electrode potentialoxidation potential- reduction potential, measurement and applications - electrochemical
series and its significance - Nernst equation (derivation and problems). Corrosioncauses- factors- types-chemical electrochemical corrosion (galvanic, differential aeration),
corrosion control - material selection and design aspects - electrochemical protection –
sacrificial anode method and impressed current cathodic method. Paints- constituents and
function. Electroplating of Copper and electroless plating of nickel.
Introduction- nuclear energy- nuclear fission- controlled nuclear fission- nuclear fusiondifferences between nuclear fission and fusion- nuclear chain reactions- nuclear reactor
