00:00 | Hello. Welcome to this spoken tutorial on Material required to construct a biogas plant. |
00:09 | In this tutorial, we will learn about:the various materials required to construct a biogas plant |
00:18 | Area required to construct the plant |
00:22 | The site No. of days required for construction and the best time to construct the plant. |
00:32 | Let us begin. The materials required to construct a biogas plant can be procured from any hardware & cement shop. |
00:44 | The following materials are required to construct the plant: |
00:49 | cement 14 packs, |
00:51 | gravel – half brass, |
00:55 | sand - 1 brass, |
00:57 | 3 bundles of chicken mesh- 30 feet each, |
01:02 | weld mesh sheet of size 3 feet x 4 feet with 1 inch x 1 inch of the hole size, |
01:11 | 12 feet of 6 mm steel rods- 35kgs, |
01:18 | 1 kg of steel wire to be cut into 7-8 inches per piece, |
01:27 | bricks 3, 2kg of white cement, |
01:31 | 1 kg of lime powder, |
01:34 | jute gunny bags- 25 approximately, |
01:38 | plastic sheet- 13 feet x 10 feet and |
01:43 | 7 bamboo sticks of approximate size - 3.5 feet |
01:49 | Liquid waterproofing material - 1 litre |
01:53 | wooden square trowel with a concave bent from inside. |
01:58 | These are especially used for smoothening the cement plaster on the dome of the biogas plant. |
02:06 | metal square trowel, |
02:08 | shovel,small trowel, hook, |
02:12 | trough with a capacity of 10 kgs. |
02:16 | scissor to cut the chicken mesh, |
02:18 | one measuring tape, |
02:20 | 1kg of newspaper, |
02:23 | scale with two hooves at the two ends and |
02:28 | an iron rod with hollow ends at either sides. |
02:33 | We will now look at other items required to construct the plant such as tubes, pipes and valves. |
02:45 | We require main gas control valve of size 1 inch, metal pipe to be connected from the center of the dome, 30 cms x 1 inch of diameter. |
03:01 | This will be the main gas pipe. |
03:04 | Gas conveyor pipe of 1/2 inch diameter: |
03:08 | the length of this pipe will depend upon the distance between biogas plant and the kitchen. |
03:17 | Inlet pipe connected from mixing tank to digester tank should be 6 inches diameter and approximately 5 feet of length. |
03:30 | Another outlet pipe of 6 inches diameter to be connected from slurry tank to the slurry collection pit. |
03:39 | If the outlet pipe is not required, alternately construct a drain between slurry tank and the slurry collection pit as shown. |
03:52 | The depth of this slurry collection pit can be between 4 to 6 feet. |
04:00 | The slurry collected in this pit can be manually poured in the fields. |
04:06 | We also require a safety-valve of 1 inch. |
04:11 | Approximately, 6 metres of rubber hose pipe of ½ inch diameter. |
04:19 | This rubber hose pipe will be used to convey the gas from the safety valve to the kitchen stove. |
04:27 | 2 Vohj clips are required to secure the pipe. |
04:32 | A few other items like synthetic resin adhesive 250 ml and teflon tape. |
04:42 | Always use good quality cement, gravel and sand. |
04:48 | These are really important for the durability of the biogas plant. |
04:54 | Let’s now talk about the area, site, No. of days required for construction and best time to construct the plant. |
05:06 | To construct the biogas plant, we need approximately 12 feet X 8 feet of land, near the house. |
05:16 | The site should be such that construction cost is minimized and it receives ample sunlight to maintain the right temperature inside the biogas plant. |
05:31 | The selected site should also ensure easy operation and maintenance of mixing tank, digester tank, main gas control valve to switch off gas inflow and the slurry tank. |
05:49 | The site should also be located near the source of animal dung and the toilet. |
05:57 | This will help to easily operate the plant and avoid wastage of raw materials. |
06:06 | The total no. of days required to complete the civil work of a biogas plant are 3 to 5 days. |
06:17 | The best time of the year to construct the biogas plant is between November and June. |
06:27 | Constructing biogas plants during the rainy season is best avoided, as it becomes messy. |
06:36 | This brings us to the end of this tutorial on the material required to construct a biogas plant. |
06:45 | The construction part of the biogas plant will be explained in next tutorial under the same series. |
06:55 | Let’s Summarize. |
06:57 | In this tutorial, we learnt: The material required to construct a biogas plant |
07:06 | Area required to construct the plant |
07:09 | Preferred site and |
07:12 | No. of days required along with the best time to construct the plant. |
