“…Also, for a required production rate of biogas, the period to achieve the optimum temperature should be reduced. Tiwari et al (1992) have suggested heating of the slurry by a heat exanger connected to a flat plate collector. Gupta et al (1998), Sodha et al (1987Sodha et al ( , 1989, Tiwari et al (1997) have suggested installation of PVC greenhouse type structure over a biogas plant.…”

In this paper, an attempt has been made to design and test the performance of a portable floating type biogas plant of volume capacity 0.018 m3 for outdoor climatic condition of New Delhi, India. The field study has been carried under the monsoonal season of New Delhi, India. In this experiment, we have taken an aluminium made digester of 30 Kg slurry capacity for batch system. In the batch system, the slurry has been added once to the digester for whole duration of the process. The rate of biogas production with slurry temperature has been observed. It has been observed that (i) the biogas production depends strongly on slurry temperature and (ii) the retention period is nearly 85 days. The range of slurry and ambient temperature of atmosphere recorded during the observed period have been found as 26 to 42 ºC and 30 to 40 ºC respectively. Physical and chemical analysis of biogas and slurry have also been carried out. Further, the CO2 mitigation and carbon credit has also been evaluated for the present system.

“…In their study, either floating or fixed dome type biogas plant has been considered. On the basis of their finding, it has been concluded that active heating of slurry in digester is more effective in comparison with other heating methods [12][13][14][15]. The temperature of slurry can be increased upto optimum level (~ 37 o C) by optimizing the area of flat plate collector for a given capacity of the slurry.…”

Abstract:In this paper, the energy balance equations for the different components of hybrid photovoltaic thermal (HPVT) biogas plant have been written for quasi -steady state conditions to develop a thermal model. An analytical expression for slurry temperature has been obtained as a function of design and climatic parameters namely mass of the slurry, mass flow rate of fluid in collector, number of collectors, solar intensity, ambient temperature etc. Numerical computations have been carried out for climatic conditions of Srinagar, India. Based on mathematical computations it has been observed that the optimum slurry temperature (~ 37 o C)is achieved for a given set of design parameters of biogas plant and hybrid collectors (M S =2000,It has been observed that number of hybrid PVT collector has significant effect on slurry temperature.
