rate of evaporation

BTИ is often used in calculations of the condenser heat transfer coefficient,however,practice showed that there could be deviations between the BTИ calculation result and the actual runtime value since BTИ′s correction coefficients to the steam load and the circulating water flow were not acceptably accurate under some new conditions.

在凝汽器传热系数的计算中,通常采用的是前苏联别尔曼公式,通过实例发现别尔曼公式中凝汽器蒸汽负荷和循环水流量对传热系数的修正不足,造成了别尔曼公式计算结果与实际运行值存在偏差。
