Heat recuperator efficiency calculation

Objective: 1. With the change of preheating from 298k to 600k,the adibatic flame temperature also increases linearly 2. 1.Q = (mass_of_air*enthalpy_of_air) + (mass_of_fuel*enthalpy_of_fuel) - (mass_of_products*enthalpy_of_products) Q_specific = Q/m_of_fuel Combustion…
