| Hello and Welcome to the '''Spoken Tutorial '''on Maintenance and Repair of the '''Biogas plant.'''

|-
| 00:10
| In this '''tutorial, '''we will learn different techniques to maintain and repair- the '''Biogas plant''' and the '''Biogas''' burner

|-
| 00:27
| Periodic partial and complete cleaning of the '''Biogas plant''' is a must.

|-
| 00:36
|This will ensure that the '''Biogas plant''' runs smoothly.

|-
| 00:43
|It will also ensure efficient working of the '''Biogas plant '''for many years.

|-
| 00:52
| Let us first look into the maintenance section.

|-
| 00:58
| So, how often should one carry out maintenance of the '''Biogas plant'''?

|-
|01:07
| Maintenance should be carried out on a daily basis by doing the following-

|-
| 01:16
|Always, mix the bio-waste with water in the proper ratio.

|-
| 01:25
| This will ensure- smooth flow of the bio-waste from the mixing tank into the digester tank.

|-
| 01:36
| If adding plant waste, crush and chop the leaves up to 1-4 cms.

|-
| 01:49
| Do not feed too much straw into the digester tank as it is difficult to be digested.

|-
| 02:00
| Sticks and branches of trees should also be avoided.

|-
| 02:08
| Soap, oil, chemical, insecticide and pesticides should not be added.

|-
| 02:18
|Soil, sand or stone should also not be added.

|-
| 02:26
|As they will accumulate at the base of the digester and hinder gas production.

|-
| 02:34
| Quantity of bio-waste to be supplied depends upon the size of the plant.

|-
| 02:42
| Too much bio-waste should not be fed into the digester.

|-
| 02:47
|This will lead to shorter retention time- i.e. bio-waste will be in the digester tank for lesser time and fermentation won’t be completed.

|-
| 03:04
| Hence, bio-waste will come out in the slurry tank without being digested.

|-
| 03:12
|If less bio-waste is fed into the digester, then gas production will be low.

|-
| 03:22
| Water condensation should be checked regularly.

|-
| 03:27
| As water in the pipeline will block the passage of gas.

|-
| 03:33
| Do so, by lifting the gas pipe so that the water can run back into the digester tank.

|-
| 03:45
|Also keep a check that the slurry is being pumped out smoothly into the slurry tank.

|-
| 03:55
|Ensure that the slurry is being emptied out of the slurry tank when it is full.

|-
| 04:04
| No inflammable items like- lighter and/or cigarettes should be brought near the outlet pipe of the dome.

|-
| 04:17
| Another important thing to be done is that- Slurry in the digester tank should be completely removed once in three years.

|-
| 04:33
|This is usually done by the mason himself.

|-
| 04:40
| As shown, keep the mixing tank and the slurry tank covered.

|-
| 04:48
|This is done to ensure proper hygiene and to avoid breeding of mosquitoes near the plant.

|-
| 04:59
| Let us now look into the Repair section.

|-
| 05:06
|Repair of '''Biogas''' burner should always be done by a qualified technician.

|-
| 05:15
| What you see here is a '''Biogas''' burner with the flame.

|-
| 05:22
| To start repairing, first switch off the inflow of gas by turning off the knobs on- the hose pipe and at the burner

|-
| 05:39
|Doing so is very important.

|-
| 05:43
| What you see here is the burner without the flame after the knobs have been turned off.

|-
| 05:52
|Wait for few minutes and light the burner to ensure that gas inflow has stopped.

|-
| 06:03
| Now remove the hose pipe connected to the burner.

|-
| 06:09
|Do so by loosening the '''Vohj clip''' tightened on the hose pipe connected to the burner.

|-
| 06:19
|Once it is loosened, pull out the hose pipe.

|-
| 06:25
| Now place the hose pipe near your ear to check for the sound of gas.

|-
| 04:36
|No sound means no gas inflow and the repair work can be carried out safely.

|-
|06:47
| Now we start dismantling the burner.

|-
|06:53
| Next we will remove the debris in the burner.

|-
| 06:59
|As shown in the image, blow air through the hose-burner connector.

|-
| 07:09
|This will also help to check if air is reaching smoothly to the flame ring.

|-
|07:19
| Slightly tap the burner and then turn it upside down.

|-
| 07:26
|You can see the debris fallen from the burner.

|-
| 07:33
| In case of hard debris which cannot be removed by blowing air, a dry scrubbing pad can be used.

|-
| 07:47
| To clean the flame ring, use a pin and insert it into the holes for cleaning.

|-
| 07:58
|A ring with clean holes will ensure- smooth flow of gas and fuller flame

|-
| 08:09
| A clean ring will look like this.

|-
| 08:15
| Apart from what is mentioned, periodic inspection of the plant is necessary.

|-
| 08:24
|Inspection will help to locate cracks on the surface of the digester tank.

|-
| 08:33
|Otherwise, the generated '''Biogas '''can escape into the atmosphere through these cracks.

|-
| 08:43
|Hence, these cracks need to be sealed quickly.

|-
| 08:51
| Once in 3 years, the mason also repaints the inner wall of the digester tank

|-
| 09:03
|This is done by using White '''cement''' and synthetic resin adhesive mixture

|-
| 09:14
|This mixture will also help to seal cracks, if present.

|-
|09:23
| To make this mixture use the following- 2 Ltrs of water

|-
| 09:33
| 250 gms of Synthetic Resin Adhesive and 2 kgs of white '''cement'''

|-
| 09:49
|Mix these thoroughly and use.

|-
| 09:54
| Let us summarize: In this '''tutorial''' we learnt about different techniques to maintenance and repair the''' Biogas plant''' and the Biogas burner.

|-
