膜态沸腾膜态沸腾film boiling moto一fe一teng膜态沸腾(film boiling)在一定条件下，亚临界压力锅炉的蒸发受热面中水或汽水混合物与管壁间被一层汽膜隔开，导致传热系数急剧下降，管壁温度急剧升高，甚至出现过烧的现象。膜态沸腾又称传热恶化，按机理分为第一和第二两大类。 第一类传热恶化发生在欠热区和低含汽率区。热负荷很高时，蒸发管内壁汽化核心数剧增，汽泡生成速度超过脱离速度而形成汽膜，也称偏离核态沸腾(departure from nueleate boiling，DNB)。发生此类传热恶化时，传热系数急剧下降，壁温飞升，往往出现过烧。受热面热负荷是引起传热恶化的决定性因素，判定转入传热恶化的热负荷称临界热负荷，其他影响因素有质量流速、含汽率(或欠热值)、压力、管径及受热面状态等。 第二类传热恶化发生在含汽率较高的环状流动区。很薄的水膜被撕破或蒸发，管壁仅受蒸汽冷却，也称燕干(dry一out)，此时传热系数下降，壁温飞升(均小于第一类传热恶化)，经常伴有壁温波动(幅度为60~125℃)，常导致管壁发生热疲劳破坏。引起第二类传热恶化的决定性因素为含汽率。判定转人传热恶化的含汽率为临界含汽率。其他影响因素有质量流速、热负荷、管径及压力等。 保证一定的质量流速，采用内螺纹管、来复线管、扰流子，降低受热面热负荷等均可推迟传热恶化或改善传热恶化发生的壁温异常。 在超临界压力下，最大比热区也能发生传热恶化(又称类膜态沸腾)。在一定热负荷下，传热恶化与否，主要取决于质t流速。如果质量流速太高又会引起阻力上升。因而超临界压力锅炉可采用复合循环方式，来提高水冷壁的安全性。
