Disclosed is a mixed composition fuel produced after the combustion of hydrogen and oxygen. The mixed composition fuel produced after the combustion of hydrogen and oxygen is prepared by a process in which secondary combustion gas pyrolyzed in a steam injection-heat storage unit is mixed with a fuel in which water vapor is mixed with a water electrolysis gas. In particular, this process includes: a first step for preparing the mixed composition fuel in which the secondary combustion gas pyrolyzed in the steam injection-heat storage unit is mixed with the fuel in which water electrolysis gas and water vapor are mixed; and a second step for using combustion equipment to combust the mixed composition fuel in which the secondary combustion gas pyrolyzed in the steam injection-heat storage unit is mixed with the fuel in which water electrolysis gas and water vapor are mixed. Therefore, the present invention can solve the problem inherent in technology for improving combustion efficiency and reducing pollutants wherein the amount of water electrolysis gas that can be mixed and combusted is significantly limited because flame temperature increases when water vapor is not mixed.
