![Solve the following completely.
1. In a boiler observation made were as follows:
Rate of feed water per hour = 1,000 kg
Temperature of feed water =
30°C
Steam pressure
= 10 bar
Quality of steam = 0.9
Coal consumption rate per hour = 100 kg
Calorific value of coal = 33,000 kJ/kg
Mass of ash and unburnt coal= 10 kg/h
Calorific value of ash and unburnt coal = 3,000 kJ/kg
Quantity of flue gas/kg of coal = 20 kg
%3D
Discharged gas temperature = 300°C
Atmospheric temperature = 20°C
Specific heat of flue gas = 1.03 kJ/kg K
Calculate:
(i) Boiler efficiency.
(ii) Percentage of heat loss in flue gas.
(iii) Percentage of heat loss to ash and unburnt coal.
(iv) Percentage of heat loss unaccounted for.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb85f0ed0-3bd6-42fb-9187-1aeb63286344%2Fb6afa84f-2ab3-48e9-99e7-06ba51327cea%2Fugq8o9u_processed.jpeg&w=3840&q=75)
