Abstract

Abstract In order to increase biogas production during winter months/cold climatic conditions, a self-sustained N-photo-voltaic thermal and flat plate collectors (PVT-FPC) hybrid active heating biogas plant has been analyzed in terms of thermal energy and electrical energy. A general analytical expression for thermal and electrical energy of biogas plant has been derived as a function of climatic and design parameters from one order coupled differential equations. Various photo-voltaic thermal and flat plate collectors (N-PVT-FPC) configurations have been considered for optimizing maximum electrical and thermal energy gain for a given total number of N-PVT-FPC collectors. Based on mathematical computation for Indian cold climatic conditions, it has been found that the photo-voltaic thermal and flat plate collectors (N-PVT-FPC) combination is always better than the flat plate collectors-photo-voltaic thermal (N-FPC-PVT) collector for maximum electrical and thermal energy. Overall exergy analysis of hybrid active heating of biogas plant has also been carried out.

N-PVT-FPC混合主动供热沼气厂热电分析

摘要:为了提高冬季/寒冷气候条件下的沼气产量，对自持型n -光伏热平板集热器(PVT-FPC)混合主动加热沼气厂的热能和电能进行了分析。从一阶耦合微分方程出发，导出了沼气厂热能和电能作为气候参数和设计参数的函数的一般解析表达式。对于给定总数的N-PVT-FPC集热器，考虑了各种光伏热平板集热器(N-PVT-FPC)配置，以优化最大的电能和热能增益。通过对印度寒冷气候条件的数学计算，发现光伏集热器和平板集热器(N-PVT-FPC)组合在最大发电量和热能方面始终优于平板集热器-光伏集热器(N-FPC-PVT)组合。对沼气厂混合主动供热进行了全面的火用分析。
