Question : 182 of 200

Marks: +1, -0

The enthalpies of feed - water and steam at the exit of a boiler are 73 kJ/kg and 2800 kJ/kg respectively. Steam output is 1128.5 kg/hr. The equivalent evaporation is:

1301.4 kg/hr
1363.5 kg/hr
11 kg/kg fuel
900 kg/hr

Validate

Solution:

Given:

ṁ_s = 1128.5

kg/hr
h = 2800 kJ/kg

h_f = 73

kJ/kg
Equivalent evaporation of the boiler =

{1128.5×(2800−73)}/2257=1363.5

kg/hr
