Give answer of 1 and 2
The following data was recorded during a test
performed on a steam plant consisting of a Lancashire
boiler, economiser and a superheater.
Steam generated = 5,000 kg/hr at 14 bar pressure
Mass of coal burnt = 670 kg/hr
%3D
Calorific value of coal = 29500 kJ/kg
Temperature of feed water at entry and exit of economiser
= 30°C and 130 C respectively.
= 320 °C.
Temperature of steam leaving the superheater
Dryness fraction of steam leaving the boiler = 0.97
c, (superheated steam) = 2.3 kJ/kg-K
4.18 kJ/kg-K
Cp (water)
%3D
Calculate:
(1) Factor of evaporation.
(2) Overall efficiency of the plant.
