10MW TYPE LARGE SCALE CALORIMETER

摘要

PURPOSE: A large scale calorimeter in the 100MW class is provided to improve the accuracy for measuring data with respect to a fired object even though a large size. CONSTITUTION: A large scale calorimeter(100) in the 100MW class comprises a collection hood(110), an exhaust duct(120), a combustion gas analyzing device(130), an orifice part(140), and a guide vane(150). Combustion gas generated in a fire is gathered and flows into the collection hood for a combustion test. The exhaust duct is connected to the upper part of the collection hood and horizontally installed. The combustion gas analyzing device measures the combustion gas passing through the inner side of the exhaust duct through the collection hood. The orifice part is installed so that an exhausting speed of the combustion gas is increased. The guide vane installed between the orifice part and combustion gas analyzing device guides the combustion gas flowing to the combustion gas analyzing device to the horizontal direction at a constant concentration.
