Combustion Efficiency calculation after pre-heating using Python

Objective: Recuperator: A form of heat exchanger in which hot waste gases from a furnace are conducted continuously along a system of flues where they impart heat to incoming air or gaseous fuel. 1. Effect of pre-heating on Adiabatic Flame Temperature Combustion of Methane: `CH4+2(O2+3.76N2)=CO2+2H2O+7.52N2` Range of pre-heating…
