超临界压力锅炉超临界压力锅炉supercritical pressure boilerehoollnJ一e yol一guolu超临界压力锅炉(supereritieal pressure boil-er)主蒸汽压力超过临界压力22.12 MP。的锅炉称为超临界压力锅炉。通常大容量超临界压力电站锅炉的主蒸汽压力定在24.5 MPa左右，也有比之更高的。当主蒸汽压力达到27 MPa以上时(见蒸汽参数)，又称为超超临界压力锅炉(ultra super eritiealPressure boiler)。发展超临界或超超临界压力机组都是为了更有效地提高火力发电厂的经济性，因此对超临界压力锅炉还伴随着采用更高的汽温和更大的锅炉容t。妞临界压力锅炉技术特性由于水和蒸汽的压力超过临界压力后不可能有汽水双相混合物共存，因此超临界压力锅炉只能采用没有锅筒的直流锅炉。超临界压力也体现了当代电站锅炉最先进的技术。与亚临界锅炉相比，由于蒸汽参数更高，因此在锅炉受压元件的设计时需要采用更高等级的材质，并需要更完善的强度设计和寿命分析;由于它是直流锅炉，因此其水冷壁系统的设计与锅筒式锅炉有很大区别，并且还需要设t一套起动系统;由于超临界压力锅炉往往采用变压运行，因此在锅炉性能设计时还要兼顾超临界和亚临界各种不同运行工况时的特点，保证锅炉安全经济运行。此外，超临界压力锅炉在给水品质、自控以及防止高温部件高温腐蚀等方面，都有着更高的要求。超临界压力锅炉水冷盛与亚临界压力锅炉相比，超临界压力锅炉最大特点体现在水冷壁系统的设计方面.当代超临界压力锅炉水冷壁设计必需体现超临界、直流锅炉与变压运行的三大要素.水冷壁管圈型式、质t流速、热偏差、流量分配等都是超临界压力锅炉水冷壁设计的关键因素。水冷壁管圈型式超临界压力锅炉目前常用的管圈型式分为螺旋管圈和垂直管圈两大类型。螺旋管圈水冷壁管与水平线成一定倾角，从锅炉底部沿炉膛四周螺旋式盘绕上升，直至炉膛上部折焰角与炉膛出口处为止，通常盘绕1~2圈，螺旋倾角在100~2护之间。垂直管圈与通常的锅筒式锅炉相似，从冷灰斗至炉顶水冷壁管均作垂直布置，并且为满足变压运行需要，往往采用小管径一次上升式管圈。这两种型式在当代大容t超临界压力锅炉上都得到了广泛采用，二者在水冷壁结构设计、制造和安装等方面各有优缺点，但只要设计合理，都可以满足锅炉运行性能的要求。质t流速超临界压力锅炉水冷壁管内质量流速的合理选取十分关键，是关系到锅炉安全经济运行的重要因素.对于螺旋管圈，可以通过合理选择管径、根数和姗旋倾角等来确定合理的质量流速。
