Combustion product stream through the oxygen concentration of the oxygen consumption and calculate the heat release rate, heat release rate of the material is also the material properties of the combustion products of the combustion burner of the most important parameters, more accurately measure the material during combustion heat release rate, for predicting fire hazard prevention and fire-retardant treatment is extremely important.
