Determine the ambient temperature if the temperature of flue gases inside the chimney is 363 C and the 20 kg of air is supplied for complete combustion of 1 kg of fuel. The discharge though the chimney is maximum.
A chimney is used to develop natural draught of 20 mm of water. The ambient temperature is 30 C. Determine the chimney height if the discharge though the chimney is maximum.
The temperature of flue gases was observed to be 350 C with a chimney (natural draught) of 45 m. The same draught was developed using an induced draught fan and the temperature of the flue gases was measured to be 150 C. The mass of air supplied for complete combustion of 1 kg of fuel is 20 kg. The ambient temperature is 30 C. Assuming c<sub>p</sub> = 1.004 kJ/kg for flue gases calculate the efficiency of chimney.
