Abstract:
PURPOSE: A device for standardizing a regenerator using a ceramic honeycomb is provided to reduce pressure loss and weight, to optimize and quantify a heat storage structure and to accomplish standardization of a design method by considering the operational conditions of a furnace. CONSTITUTION: A ceramic honeycomb(3) is used instead of a ceramic spherical body for a heat storage chamber. Such operational conditions as an amount of combustion, a ratio of combustion air, the operating time of a burner and the structure are considered when designing a regenerator. Thus, weight of the regenerator is reduced and structure is compacted. Since the regenerator is designed by considering the operational conditions determined by a design standard, regeneration efficiency and waste heat recovery efficiency are maximized. Moreover, the design efficiency of a furnace is satisfied.
