This book is very helpful for those who want to prepare for the BOE examination because in this book all the topics covered which are asking in Boe examination directly and also solved boe numerical in this book which is repeated again and again into this exam.
TABLE OF CONTENTS 1. Properties of steam
Steam uses of steam table - important points to remember- conversation factors - symbols used in steam table - uses of steam table finding saturation temperature , specific volume , specific enthalpy , specific entropy , finding the condition of steam - calculations for finding enthalpy , amount of heat added , increase in volume , external work done , internal energy , specific volume , entropy , change of enthalpy , rise in temperature , dryness fraction of steam , weight and total heat of steam , degree of superheat , increase in volume , amount of steam generated and various problems - Problems for boiler operation engineering examination.
4.FUELS AND COMBUSTION
Theoretical air requirement - important points to remember - mass of air required for complete combustion- mass of products of combustion per kg of fuel - percentage composition of dry flue gases by volume - mass of carbon per kg of dry flue gases - Actual air percentage of excess air - Conversion of volume analysis of gas sample to weight analysis - Strength of mixture - volume of air gravimetric - composition of products of combustion - molecular weight - density of gas - lower calorific value - higher calorific value- problems from boiler operation engineering examination
Important points to remember - calculations for finding draught in mm of water column produced by chimney - minimum height of chimney required - velocity of flue gases - efficiency of chimney - mass of air actually used - % of excess air - power required to drive fan - problems from boiler operation engineering examination
Important points to remember - Theoretical mean effective pressure - back pressure - indicated power of engine , break power of engine.
Important points to remember - Quality of cooling water required - dryness fraction of steam entering condenser - amount of heat removed - rate of cooling water flow - weight of cooling water - number of tubes used in condenser - problems from boiler operation engineering examination
Important points to remember - calculations for finding power developed , power at the coupling , internal efficiency of the turbine - problems from boiler operation engineering examination.
