UNIT I WATER TECHNOLOGY 9
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 9
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- typeschemical,
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 power
generator- classification of nuclear reactor- light water reactor- breeder reactor- solar energy
conversion- solar cells- wind energy. Batteries and fuel cells:Types of batteries- alkaline batterylead
storage battery- nickel-cadmium battery- lithium battery- fuel cell H2 -O2 fuel cellapplications.
UNIT IV ENGINEERING MATERIALS 9

Refractories: definition, characteristics, classification, properties – refractoriness and RUL,
dimensional stability, thermal spalling, thermal expansion, porosity; Manufacture of alumina,
magnesite and silicon carbide, Portland cement- manufacture and properties - setting and
hardening of cement, special cement- waterproof and white cement–properties and uses. Glass
- manufacture, types, properties and uses.

UNIT V FUELS AND COMBUSTION 9
Fuel: Introduction- classification of fuels- calorific value- higher and lower calorific values- coalanalysis
of coal (proximate and ultimate)- carbonization- manufacture of metallurgical coke (Otto
Hoffmann method) - petroleum- manufacture of synthetic petrol (Bergius process)- knockingoctane
number - diesel oil- cetane number - natural gas- compressed natural gas(CNG)-
liquefied petroleum gases(LPG)- producer gas- water gas. Power alcohol and bio diesel.
