An industrial boiler with a household volume of 20.1 m^3 burns oil with a mass flow of 380 kg/h that has a PCS of 43 MJ/kg and a PCI of 40.5 MJ/kg.
a) What nominal power does the boiler have?
b) Think if the present heat release regime is admissible for a home with refractory walls.
c) What is the composition of the leaks if the combustion is with 20% excess air and the composition of the oil is (carbon 84%, hydrogen 14%, oxygen 2%).
