A boiler uses 20 kg of air per kg of fuel. The fuel consumption is 33 kg/sec and actual draught required is 18 mm of water taking into account all losses. Determine the chimney height and its diameter if the actual velocity of flue gases is 0.38 times the theoretical velocity due to friction. The surrounding is at 25°C and flue gases temperature is 230°C.
