基于能量价值分析的给水泵驱动方式的技术经济论证

Technico-economic Argumentation of a Feedwater Pump Drive-mode Based on an Energy Value Analysis

通过对发电厂各种能量的价值分析 ,提出了“能量价值分析”原理 ,按此原理推导出了“综合成本煤耗率”的计算公式 ,此方法克服了传统热力学分析方法的局限性 ,把热力学和经济学有机地结合在一起 ,成为在市场经济条件下发电厂技术经济分析的科学方法 ,找到了市场经济条件下发电厂降低成本的有效途径和节能分析准则 ,并成功地应用于给水泵驱动方式的技术经济论证。

Through the value analysis of various forms of energy produced by a power plant the authors have put forward a principle of 'energy value analysis'. On the basis of this theory deduced is a calculation formula for 'comprehensive cost-based coal consumption rate'. Under this approach it is possible to overcome the limitation of a traditional thermodynamics-based analytical method. By way of organically integrating the theory of thermodynamics with economics a scientific method is found for the technico-economic analysis of power plants under market-economy conditions. Moreover, an effective approach for cost reduction at power plants under market-economy conditions and the criteria for analyzing energy savings have also been identified. All the above has been successfully applied in the technico-economic argumentation concerning the drive mode for a feedwater pump.
