【正文】 basis) in experimental and con trol biogas plants under the parative study in hilly region is shown in this study,the cooking was not done in winter period due to low availability of biogas and the gas generated during this period was utilized for lighting application so that the illumination from the biogas lamp also liberated heat radiation to raise the room temperature conditions for fort of major portion of the biogas yielded was utilized for lighting application against cooking both in experimental and control biogas plants in the present study. The temperature reversal during day and night variationsdiffers far from the ambient conditions。it affects the bacterial growth ,reduction in the performance is encountered in the existing conventional ,use of plastic in biogas plant fabrication will overe all the above the conventional designs once installed can not be relocated on any other ,the plastic biogas plant identi?ed in this present study can be shifted to any convenient place at any time (can be placed outdoors in summer season and indoors during winter season). The sand and sediment depositions in the conventional Indian 太陽能增溫丘陵地區(qū)沼氣廠實地考察 10 standard design if not removed at regular intervals will bring down the retention time and ultimately the drop in its over,the gas yield recorded in experimental biogas plant was % higher than the control biogas plant. Table 2Time consumption for cooking and lighting from experimental and control biogas plant (seasonal basis) Seasons Time consumption(hrs:min) Plastic tank with greenhouse canopy (experimental)biogas plant Deenabandhu without greenhouse canopy (control)biogas plant Cooking Lighting Cooking Lighting Winter(October–December,2020) 0:28 0:18 Postmonsoon(January–March,2020) 0:25 0:42 0:15 0:28 Summer(April–June,2020) 1:26 0:47 0:27 0:33 Premonsoon(July–September,2020) 0:25 0:33 0:13 0:22 Total time consumption per year 4:10 4:50 2:05 3:05 In the present study, the testing of plastic as an alternate building material for biogas plant in hilly regions with solar greenhouse proves to be effective than other conventional masonry model being adopted in most part of yearly average slurry temperatures recorded during the study period was ℃ in experimental and control biogas plants against the ambient of 17℃ .It is evident that the rise in slurry temperature recorded in plastic and conventional control biogas plants and % higher than the ambient condition production in the winter season recorded was lower than other major portion of the biogas produced was utilized for lighting application against cooking both in experimental and control biogas plants in the hilly the basis of generated experimental database of the present investigation,it can be concluded that there is a good scope to employ plastic material for biogas plant construction and further research may substantiate this approach. 沈陽農(nóng)業(yè)大學學士學位論文外文翻譯 11 References [1]Bansal,.,Bhand,.,Ram,S,Singh,K., study of a greenhouse concept on conventional biogas systems for enhancing biogas yield in winter months[M],International Journal Energy Resources9,119–128.
