工作中研究了加热器倾斜角对热量和凝结水逆流运动时泛洪模式边界的影响。确定洪水模态的边界由库塔特拉泽稳定性准则定义。接收用于计算取决于加热器的倾斜角和压力标准的“溢流”边界的标准方程。在加热器的所有操作模式下，倾斜角度对冷凝时的热辐射没有任何影响。当热负荷超过临界值时，冷凝时的热交换强度几乎降低两倍。得到了计算加热器内冷凝传热系数的判据方程。提供稳定工作模式的加热器的几何参数在此确定。
The influence of a tilt angle of a heater on the borders of the flood mode at the heat and condensate counterflow movement is investigated in the work. It is established that the borders of the flood mode are defined by Kutateladze's stability criterion. Criterion equation for the calculation the borders of "flood" depending on a tilt angle of a heater and pressure criterion is received. A tilt angle does not have any influence on heat irradiation at condensation at all operating modes of a heater. The intensity of heat exchange at condensation is reduced almost twice at heat loads that are more than critical. Criterion equations for the calculation of heat-transfer coefficient at condensation inside a heater are received. The geometrical parameters of a heater providing steady modes of its work are determined there.
