OBJECTIVES:
To make the students conversant with boiler feed water requirements, related problems and
water treatment techniques.
To develop an understanding of the basic concepts of phase rule and its applications to single
and two component systems and appreciate the purpose and significance of alloys.
Preparation, properties and applications of engineering materials.
Types of fuels, calorific value calculations, manufacture of solid, liquid and gaseous fuels.
Principles and generation of energy in batteries, nuclear reactors, solar cells, wind mills and
fuel cells.
UNIT I WATER AND ITS TREATMENT
Hardness of water – types – expression of hardness – units – estimation of hardness of water by
EDTA – numerical problems – boiler troubles (scale and sludge) – treatment of boiler feed water –
Internal treatment (phosphate, colloidal, sodium aluminate and calgon conditioning) external
treatment – Ion exchange process, zeolite process – desalination of brackish water – Reverse
Osmosis.
UNIT II SURFACE CHEMISTRY AND CATALYSIS
Adsorption: Types of adsorption – adsorption of gases on solids – adsorption of solute from
solutions – adsorption isotherms – Freundlich‘s adsorption isotherm – Langmuir‘s adsorption
isotherm – contact theory – kinetics of surface reactions, unimolecular reactions, Langmuir –
applications of adsorption on pollution abatement. Catalysis: Catalyst – types of catalysis – criteria
– autocatalysis – catalytic poisoning and catalytic promoters – acid base catalysis – applications
(catalytic convertor) – enzyme catalysis– Michaelis – Menten equation.
UNIT III ALLOYS AND PHASE RULE
Alloys: Introduction- Definition- properties of alloys- significance of alloying, functions and effect of
alloying elements- Nichrome and stainless steel (18/8) – heat treatment of steel. Phase rule:
Introduction, definition of terms with examples, one component system -water system – reduced
phase rule – thermal analysis and cooling curves – two component systems – lead-silver system –
Pattinson process.
UNIT IV FUELS AND COMBUSTION
Fuels: Introduction – classification of fuels – coal – analysis of coal (proximate and ultimate) –
carbonization – manufacture of metallurgical coke (Otto Hoffmann method) – petroleum –
manufacture of synthetic petrol (Bergius process) – knocking – octane number – diesel oil – cetane
number – natural gas – compressed natural gas (CNG) – liquefied petroleum gases (LPG) – power
alcohol and biodiesel. Combustion of fuels: Introduction – calorific value – higher and lower calorific
values- theoretical calculation of calorific value – ignition temperature – spontaneous ignition
temperature – explosive range – flue gas analysis (ORSAT Method).
UNIT V ENERGY SOURCES AND STORAGE DEVICES
Nuclear fission – controlled nuclear fission – nuclear fusion – differences between nuclear fission
and fusion – nuclear chain reactions – nuclear energy – light water nuclear power plant – breeder
reactor – solar energy conversion – solar cells – wind energy. Batteries, fuel cells and
supercapacitors: Types of batteries – primary battery (dry cell) secondary battery (lead acid
battery, lithium-ion-battery) fuel cells – H2-O2 fuel cell.
OUTCOMES:
The knowledge gained on engineering materials, fuels, energy sources and water treatment
techniques will facilitate better understanding of engineering processes and applications for
further learning.
