“Energy and Efficiency analysis of 210MWe coal base Thermal Power Plant with running parameters” Goutam Khankari‚DVC‚Kolkata. INTRODUCTION Power projects are essentially capital intensive. Not only they involve a highly initial cost which is around Rs. 4.5 to 5.0 crores per MW for coal-based plants but also huge operation cost. The running expenses of a 210MW thermal power station may range around thirty crores every month and usually about 80% of this goes towards the fuel cost. Not only fuel

Thermochemistry Lab #2 - Heat of Reaction - Hess’s Law Return The foundation of the study of thermochemistry was laid by the chemist Germain Hess‚ who investigated heat in chemical reactions during the last century. One statement of the law that bears Hess’s name says: The enthalpy change for any reaction depends on the products and reactants and is independent of the pathway or the number of steps between the reactant and product. In this experiment‚ you will measure and compare

substance condenses. The temperature does not change during this process‚ so heat released goes directly into changing the state of the substance. It is expressed as kg/mol or kJ/kg. The energy released in this process is called heat of condensation. The heat of condensation of water is about 2‚260 kJ/kg‚ which is equal to 40.8 kJ/mol. The heat of condensation is numerically exactly equal to the heat vaporization‚ but has the opposite sign. In the case of evaporation‚ the energy is absorbed by the substance

this lab‚ we are now able to calculate the molar heat of combustion for paraffin‚ since we have the difference of the mass in candle before/after and the periodic table of elements (for converting g to moles of paraffin). Molar heat of combustion = (kJ of heat)/(mole of fuel) However‚ we do not know how much heat was released nor the mole of fuel (paraffin). In order to find the amount of heat released‚ we use the formula: g=mcΔT. Here‚ g represents the heat‚ m represents the mass of water‚ ΔT represents
