چکیده
About 33% of the thermal energy produced in nuclear reactions is converted into electricity. The remaining 67 released, for example, sea, etc., as waste heat. Therefore, heat recovery and its use power plants (NPPs) are important increasing generation efficiency. this paper, an absorption refrigerator using reactor cooling water (waste heat) seawater sources was used to generate cold heat, where a gas hydrate cycle (GHC) introduced temperature difference between NPP attempt increase main specifications, including system (GPS) performance, were inferred from results previous experiments. In order clarify economics system, discounted cash flow (DCF) method proposed reveal payback period investment. Also, case study analysis, typical Japanese (Kyushu Electric Power Co., Ltd., Genkai Unit 4, pressurized with rated output 1180 MWe 3423 MWth) investigated. As result, it found that can improve efficiency by 8.7%. also showed end GHC more than 40% simple integration balance net present value 11 years. DCF 19.8

Low-Grade Waste Heat Recovery for Power Production using an Absorption-Rankine Cycle
An investigation of heat recovery for power generation using an absorption-Rankine cycle with a low temperature waste heat source was conducted. In such a cycle, the condenser and boiler of a conventional Rankine system are replaced with an absorber and desorber. A recuperative solution heat exchanger is also incorporated between the absorber and desorber to minimize the external heat input. An...
متن کاملWaste Heat Recovery of a PEMFC System by Using Organic Rankine Cycle
In this study, two systems are brought forward to recover the waste heat of a proton exchange membrane fuel cell (PEMFC), which are named the organic Rankine cycle (ORC), and heat pump (HP) combined organic Rankine cycle (HPORC). The performances of both systems are simulated on the platform of MATLAB with R123, R245fa, R134a, water, and ethanol being selected as the working fluid, respectively...
متن کاملAn Improved System for Utilizing Low-Temperature Waste Heat of Flue Gas from Coal-Fired Power Plants
In this paper, an improved system to efficiently utilize the low-temperature waste heat from the flue gas of coal-fired power plants is proposed based on heat cascade theory. The essence of the proposed system is that the waste heat of exhausted flue gas is not only used to preheat air for assisting coal combustion as usual but also to heat up feedwater and for low-pressure steam extraction. Ai...
