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

Image-Caption: Building a Biogas Plant |
In the earlier tutorial, we learnt how to build a Biogas plant. |
[[Image:]]
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 were:
Cowdung 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 figure-
Raw material should be fed into the mixing tank through the inlet pipe. |
Slide 4
How much of the raw materials should be added to the Biogas plant? |
At this point, the important question is-
How much raw material should be added to the Biogas plant? |
[[Image:]]
[[Image:]][[Image:]] |
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? |
[[Image:]][[Image:]]
Image-Caption: Mixing of raw materials and water in the inlet tank. |
To add the raw material into the inlet tank-
1. first, mix the raw material and water properly in the ratio of 1:1 2. and then put this mixture into the feeding tank-

Note that, the time required for fermentation depends upon-
For eg. fermentation in warmer regions-
|
[[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. |

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:]]
Image-Caption: No LPG Burners Show Red Cross Mark denoting danger |
Please note, an LPG burner should not be used for Biogas. |
Why LPG burner should not be used for Biogas? | Why 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 like LPG stoves-
Biogas stoves are also available in:
|
[[Image:]]
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? |

To buy the Biogas burner, one needs to contact the concerned-
You can get the further contact details in the downloadable section. |
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 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
Do’s and Don’ts for running a Biogas plant |
Some Do’s and Don’ts for running a Biogas plant are- |

|
Some safety measures to be followed when using the Biogas burner. |
[[Image:]]
Image-Caption: Switch OFF the safety valve when the burner is not in use. (Point#1) [[Image:]] Image-Caption: Removing condensed water.
|
* After every 4-5 days, drain out condensed water if any
This will ensure that-
