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.
