摘要
Abstract
To accurately calculate the terminal temperature difference of a double-back pressure condenser t0 better guide the actual operation of the unit,three methods for calculating the condenser terminal difference are compared and analyzed through case studies from three power plants.The conclusions indicate that,Method One results in an overall lower terminal difference value,which could lead to misjudgment.Method Two calculates the terminal difference for the low-pressure condenser in the three cases,showing values approximately 3.0 ℃,9.0 ℃ and 0.5 ℃ higher than those for the high-pressure condenser,respectively.Method Three obtains the precise condenser terminal difference by adding the circulating water outlet temperature measurement point for the low-pressure condenser.Therefore,the calculation method for the terminal temperature difference of a double-back pressure condenser based on adding a circulating water outlet temperature measu-rement point for the low-pressure condenser provides more significant guidance for the actual operation of the unit.关键词
