    Abstract
    Procedures to obtain accurate heat flux measurements from a 50 mm diameter gas-fueled burner using a diluent fuel gas mixture were examined that required following steps. Local heat flux measurements on the surface of a thick porous copper plate burner were corrected with a pure convective burning assumption and stagnant layer solution. Calibration procedures for thermopile-type heat flux gauge was developed and compared with NIST BFRL heat flux gauge calibration system. Calibration of gauges has found to be possible without controlling the temperature. The absorptivity and emissivity of the coating used on the burner and heat flux gauges were measured via calibrated heat flux gauges and copper slug calorimeter. Independently, an apparatus was designed, built, and calibrated to measure burner flame radiant fraction. The heat flux distribution at the burner was measured. Sample measurements were taken to show accurate measurements and potential analysis of the collected burner data is examined.
