Image-Caption:Testimonial |
You will also see testimonial of Biogas users. |

Image-Caption: Household food waste [[Image:]] Image-Caption: Cow Dung |
Recollect, an earlier tutorial that mentioned-
The raw materials to be added to the Biogas plant, which were:
Cow-dung forms a favorable anaerobic environment for generation of Biogas. |
Slide 3
When should the raw material be added in the Biogas plant ? |
So, when should the raw materials be added in the Biogas plant? |
[[Image:]]
Image-Caption: Add raw-material to Biogas Plant on 18th day. |
Once the civil work is over, the plant is left for curing for 17 days.
On the 18th day, first load of raw materials can be fed into the plant. |
Video cum Image-Caption: Feeding the waste material to Biogas plant through inlet pipe | As shown in this image-

Slide 4
How much of the raw materials should be added to the Biogas plant? |
At this point, the important question is-
|

The answer is-
|
Slide 5
How to add the raw material into the inlet tank? |
Next, we will learn how to add the raw material into the inlet tank. |

Note that, the time required for fermentation depends upon-
For eg.
|
[[Image:]]
Image-Caption: Leave raw material for 4-5 days in the digester tank for fermentation. |
So, in warmer regions, leave the raw material in the digester tank for 4-5 days. |

Slide 6
What are the different ways to use slurry? [[Image:]] Animation of gas-pressure mechanism to remove slurry from Biogas plant. |
The different ways to use this slurry are as follows: |
[[Image:]]
Image-Caption: Slurry being manually poured in the fields as manure. |
1. It can be directly sent into the farms through drains 2. It can be manually poured into the nearby fields and 3. Can also be dried in drying pits to be used as dry manure |
Slide 7
Choosing the right burner for using the Biogas |
Next, we will talk about choosing the right burner for using the Biogas. |
[[Image:]]
Image-Caption: Biogas Burner connected to Biogas Plant via Gas Conveyor Pipe |
The gas that is generated in the plant is conveyed through the main gas pipe.
This main gas pipe should further be connected to an appropriate burner. |
So which burner should be used? | So which burner should be used? |
Slide 8
Two types of burners available are:
|
The two types of burners available are-
|

Image-Caption: No LPG Burners Show Red Cross Mark denoting danger |
Please note, an LPG burner should not be used for Biogas. |
The reason is- LPG burners are specifically used for high compression LPG only. Hence, LPG burners are not advisable for Biogas usage. |
The reason is- LPG burners are specifically used for high compression LPG only. Hence, LPG burners are not advisable for Biogas usage. |

Image Caption: Cast Iron Burner |
For using Biogas, it is best to buy a burner made of cast-iron due to its durability. |
Slide 9
Two types of Biogas burner models are:
|
It is to be noted that -
|

Image Caption: Typical Biogas Burner (Single Burner Model) |
Single burner stove is of 8 cubic feet size |
[[Image:]]
Image Caption: Typical Biogas Burner (Double Burner Model) |
Double burner stove is of 16 cubic feet size |
Slide 10
Where to procure Biogas burners from? |
So, where to procure Biogas burners from? |

Image-Caption: KVIC, Govt. of India |
To buy the Biogas burner, one needs to contact the concerned-
|
Slide 11
How to confirm if Biogas has been generated? |
To confirm the generation of Biogas do the following. |
[[Image:]]
Image-Caption: Lighting matchstick to check if Biogas is generated. |
Light the burner and check the flame for the Biogas. |
[[Image:]]
Image-Caption: Family using Biogas for cooking |
The gas generated will be sufficient for the cooking needs of a family of 4-5 members. |
Slide 12
