  17. The condensing length increases with the boiler heating power and air content increasing, while it decreases with the system pressure increasing. under the normal pressure, the wall temperature and the centerline temperature along the condensing length nearly remain constant for pure steam, while they decrease continuously for steam / air mixture. however, when the steam condenses over, the temperatures drops rapidly

  18. This means the saturation degree of concrete is different. by means of analyzing the l9 ( 34 ) orthogonal table, the air content is the chief factor, the second factor is water binder ratio and the third is mineral admixture in both high water pressure and low water pressure. the water saturation degree of concrete in damaging point ( e6 / e0 = 60 % ) can be found by measuring the dynamic modulus of elasticity after six freezing - thawing cycles
