| Abstract: | According to the broken problem of heating furnace by adopting the honeycomb regenerator,by using the numerical simulation technology,the numerical simulation experiment about the flowing gas inside the regenerative burner at cold gate is researched.The velocity decentration phenomenon can be clearly seen during the regenerative and exothermic process inside the regenerative burner.According to the research,it is the main reason for the efficiency decrease of regenerative burn and ceramic honeycomb damage. |
