| Abstract: | This paper introduces the calculation method of cylinder effect and heat consumption of high-voltage cylinder,medium-voltage cylinder and low-voltage cylinder and deduces the relation between cylinder effect and heat consumption,and taking sub-critical 600 MW unit in a power plant for example,adopts experimental data of thermal performance under different working conditions to calculate the effect of high-voltage cylinder,medium-voltage cylinder and low-voltage cylinder,and analyzes how cylinder effect influences heat consumption under different working conditions and gives reasonable evaluation on the running economy of this unit. |
