摘 要: 采用水平-上升管组合法测量垂直上升管内气水两相流动在泡状流和弹状流情况下的截面含气率,同时应用理论模型对结果进行预测,预测值与测量结果吻合良好,从而证实此方法在工程应用中是一种简单、准确、可行的测量方法。 Abstract Based on the primaryel ements of Venturi wind flow instruments and by using the principle of temperature-pressure correction and compensation of flue gas mass flow,the author has configured the secondary instruments with DDZ-Ⅲ electrical unit and made them applicable to the Venturi wind flow instruments.These instruments are very convenient and accurate for boiler combustion air flow measurement and provide necessary con ditions for the automatic control of boiler combustion.
