 Types of fuels, calorific value calculations, manufacture of solid, liquid and gaseous fuels.

UNIT I                             WATER TECHNOLOGY

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 foaming- desalination of brackish water –reverse osmosis.

UNIT II                          ELECTROCHEMISTRY AND CORROSION

Electrochemical cell - redox reaction, electrode potential- origin of electrode potential- oxidation
potential- reduction potential, measurement and applications - electrochemical series and its
significance - Nernst equation (derivation and problems). Corrosion- causes- 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.

UNIT III                       ENERGY SOURCES

Introduction- nuclear energy- nuclear fission- controlled nuclear fission- nuclear fusion- differences
between nuclear fission and fusion- nuclear chain reactions- nuclear reactor power generatorclassification
of nuclear reactor- light water reactor- breeder reactor- solar energy conversion- solar
cells- wind energy. Batteries and fuel cells:Types of batteries- alkaline battery- lead storage batterynickel-
cadmium battery- lithium battery- fuel cell H2 -O2 fuel cell- applications.

UNIT IV                      ENGINEERING MATERIALS
