Sloped solar chimney power plant (SSCPP) could be one of the appropriate technologies for powering Nepalese communities. The main components of the plant are chimney, collector and power-generating unit. In this study, the mathematical evaluation of the SSCPP has been conducted for the estimation of the power generation in Nepalese context. For the analysis, the mathematical models have been developed from the governing equations. The parameters such as chimney height and radius, collector radius, ambient temperature and solar insolation have been taken as inputs for simulation of the overall system. The output parameters such as overall system efficiency, chimney efficiency, air velocity, power output from the turbine and electrical power from the proposed system have been evaluated. The results showed that power developed by air, turbine power and electrical power is 120, 66 and 44 kW, respectively. The developed power is estimated when the height and the radius of the chimney were 190 and 5 m, respectively. It is seen that ambient temperature and velocity of air also play an important role in the power generation. The performance influencing the power output based on turbine pressure ratio, thermal conductivity and specific heat capacity of soil and the mass flow rate have also been estimated. Besides, the solar insolation data were taken for five different regions of Nepal to find the power generation and collector efficiency.

尼泊尔不同地区的倾斜太阳能烟囱发电厂的数学评估

倾斜的太阳能烟囱发电厂(SSCPP)可能是为尼泊尔社区供电的合适技术之一。该厂的主要组成部分是烟囱,集热器和发电装置。在这项研究中,对SSCPP进行了数学评估,以评估尼泊尔环境下的发电量。为了进行分析,已经从控制方程中开发了数学模型。诸如烟囱高度和半径,收集器半径,环境温度和日照等参数已被用作模拟整个系统的输入。已评估了输出参数,例如总体系统效率,烟囱效率,风速,涡轮机输出的功率以及所提出系统的电能。结果表明,力量是由空气产生的,涡轮功率和电功率分别为120、66和44 kW。当烟囱的高度和半径分别为190和5 m时,可以估算出所产生的功率。可以看出,环境温度和空气速度在发电中也起着重要作用。还根据涡轮压力比,土壤的热导率和比热容以及质量流量估算了影响功率输出的性能。此外,还对尼泊尔五个不同地区的日照数据进行了采集,以了解发电量和集热效率。可以看出,环境温度和空气速度在发电中也起着重要作用。还根据涡轮压力比,土壤的热导率和比热容以及质量流量估算了影响功率输出的性能。此外,还对尼泊尔五个不同地区的日照数据进行了采集,以了解发电量和集热效率。可以看出,环境温度和空气速度在发电中也起着重要作用。还根据涡轮压力比,土壤的热导率和比热容以及质量流量估算了影响功率输出的性能。此外,还对尼泊尔五个不同地区的日照数据进行了采集,以了解发电量和集热效率。
