摘要

随着火电机组规模扩大,常规火电厂产能热效率利用已达瓶颈。且受到朗肯循环参数限制,发电过程中水蒸气热损耗较高,并会伴随着一定程度上的环境污染。文中基于卡琳娜循环技术,提出一种针对火电机组的降耗提效方案。通过深入分析卡琳娜循环工作原理,将其与火电机组循环发电过程结合应用,充分发挥循环优势,突破热转化效率瓶颈,进一步提升火电机组管道余热及排气凝结热利用率。此外,该种技术可深度利用化学能转化热能循环过程中存在的各类固有热损,完成降低热耗、提升发电效率的双向优化。经实际运行测试结果表明:此技术能在不影响原电场循环热效率的前提下,提升机组发电功率近1%。

Abstract:

With the expansion of thermal power unit, the utilization of thermal efficiency of conventional thermal power plant has reached the bottleneck. The limit parameters of Rankine cycle power generation process, water vapor heat loss is higher, and will be accompanied by a certain degree of environmental pollution. In this paper, based on the Karina cycle technology, a scheme for reducing consumption of thermal power units is proposed. By analyzing the working principle of Karina cycle and combining it with the cycle generating process of thermal power units, we should give full play to the advantages of circulation and break through the bottleneck of thermal transformation efficiency, and further improve the utilization of heat and exhaust condensing heat of thermal power units. Besides, this technology can make full use of chemical energy to transform all kinds of inherent heat loss existing in heat cycle process, and complete two-way optimization of reducing heat consumption and improving power generation efficiency. The test results show that the power generation power of the lifting unit can be nearly 1% without affecting the thermal efficiency of the original electric field cycle.

Keywords: Karina cycle   thermal power unit   consumption reduction and efficiency improvement   steam turbine   pipeline waste heat   condensation heat power generation
