节能的冷凝式供热锅炉 总被引:9,自引:1,他引:8
冷凝式锅炉由于利用烟气水中蒸汽的潜热,可将热效率提高到100%以上(仍按燃料低发热量计)。且排烟中有害物浓度大大降低,可减轻对大气的污染,有利于环保。50kW以下的锅炉的凝水可不用各和处理直接排放。因锅炉增设冷凝部分及烟道、烟囱需防腐而啬的费用可在2 ̄4年内回收,这种锅炉燃用液体、气体燃料和应用于低温热水供热系统时节能效益尤为明显,应大力推广使用。 相似文献

The performance of a normal micro gravitational heat pipe was investigated using the analytical and numerical models previously developed. An innovative structure of the heat pipe, i.e. the micro gravitational heat pipe with artery, was then proposed in an attempt to overcome some of the drawbacks of the normal pipe. The thermal behaviour of the new type of heat pipe was simulated, and this was compared with that of a normal micro heat pipe. A performance estimation of both pipes was carried out based on the simulation results. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献

Heat pipes (HPs) play a pivotal role in efficiently managing the thermal challenges posed by high heat flux devices. To facilitate their operation at extremely low temperatures, specialized working fluids with low-boiling points are a necessity. HPs serve as efficient heat exchanger (HEX) in diverse applications, such as heat pumps and heat-transfer components. In the realm of space applications, HP is indispensable for cooling electronic components within two-phase thermal control systems. Notably, the recent significant reduction in HP production costs has paved the way for synergizing HP with HEX, promising substantial energy savings. This comprehensive review centers its focus on the advancements in HEX-based flexible HP systems. It critically evaluates various performance models and investigates key findings from a multitude of literature papers that pertain to HEX applications. The review encompasses a wide spectrum of innovations, including conventional, pulsating, and thermosyphons (gravity-assisted) in HEX. It further explores studies on recuperative and regenerative HEX configurations. The surveyed literature underscores the critical role played by the choice of operating fluid and heat load in significantly influencing HP performance. This study offers a comprehensive understanding of key outcomes, strengths, limitations, and specific applications of HP and HEX. The review also highlights the significance of operating fluid selection and considerations related to heat load while outlining exciting opportunities for future research in this domain. Moreover, it introduces several novel concepts for future studies in pertinent domains, offering promising directions for further exploration within this field. 相似文献
