Regenerative Combustion Experiment Research & The Application In The Tunnel Kiln

Regenerative combustion technology at the same time,also known as high-temperature & air combustion technology, which highlight the flue gas heat recovery capacity, low NOx and CO2 emission characteristics of a current hot spot of energy conservation, while preheating the combustion air to improve combustion efficiency, expanding the range of fuels.Firstly, the principle of regenerative combustion, combustion characteristics, domestic and foreign research and application status elaborate, focuses on experimental research explores the main factors influencing the regenerative combustion system is running, the results point guns fire stability, system commutation period, regenerator heat storage and heat release performance affect system operation stability, efficiency of the main factors. By focusing on performance ignition point guns, regenerator heat storage, heat release performance and system commutation cycle selection, obtained air-fuel ratio of 12 K, the excess air ratio a is 1.2, the amount of natural gas was 2.5 L / min, the point flame characteristics guns to achieve the ideal state of engineering applications, the ratio of air and gas, the extent of excess air, gas initial temperature is stable(flame length and stiffness) of the main factors affecting the flame, and commutation period determined by the Factors affecting flame stability, combustion chamber volume, flue gas temperature, flue gas volume, volume, etc. regenerator point guns at the same time due to the change to the cycle of the different heat storage capacity and the ability to release heat regenerator, also affected the effect of air preheating, requiring theoretical analysis and practical production combined to determine the proper commutation cycle. Final energy consumption analysis and theoretical calculation, analyze the feasibility of regenerative combustion technology applied in the tunnel kiln, to prepare for the further promotion and application of regenerative combustion technology.Through experiments gantry construction, installation, commissioning, to the gradual completion of the experiment, and finally to the successful conclusion of the overall system operation, effective verification system and its stability experiments by the various components of efficiency, to explore the main factors, and lay a solid theoretical and experimental basis for its engineering applications.
