The thermochemical properties of gases in the combustion chamber are the most significant for designing the nozzle configuration of the jet burner and for calculating the thermal characteristics of impinging jet flame.
The thermochemical calculation of air-kerosene jet burner is more troublesome than that of oxygen-kerosene jet burner due to the existence of nitrogen component. The authors carried out the thermochemical calculation of air-kerosene jet burner with an easy method. With this method an equation of fourth degree was devided into two quadratic equations by introducing two initial values. The solutions which satisfied chemical reaction, chemical equilibrium, energy conservation and total pressure were obtained.
The deduced nozzle exit temperature from the calculated combustion chamber temperature closely coincided with the measured flame jet temperature.
The following physical properties are reported:
A. relations between air-fuel ratio and (1) combustion chamber temperature (2) specific heat ratio (3) gas constant (4) partial pressures of gases (5) weight precent of toxic gases
B. relations between heat loss and (1) combustion chamber temperature (2) partial pressures of gases (3) weight percent of toxic gases
