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

| In this tutorial, we will learn different techniques to maintain and repair the biogas plant and  the '''biogas burner'''.

| Periodic partial and complete cleaning of the biogas plant is a must.  

|This will ensure that the biogas plant runs smoothly.

|It will also ensure efficient working of the biogas plant for many years.

| So, how often should one carry out maintenance of the biogas plant?  

| Maintenance should be carried out on a daily basis by doing the following.

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

|Soil, sand or stone should also not be added

|as they will accumulate at the base of the digester''' and hinder gas production.

|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.  

| Hence, manure will come out in the slurry tank without being digested.

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

| Water condensation should be checked regularly

| as water in the pipeline will block the passage of gas.

|  Do so by lifting the gas pipe so that the water can run back into the digester tank.

|Also, keep a check that the slurry is being pumped out smoothly into the slurry tank.

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

| Another important thing to be done is that slurry in the digester tank should be completely removed once in three years.

| Let us now look into the repair section.

|Repair of biogas burner should always be done by a qualified technician.

| What you see here is a biogas burner with the flame.  

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

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

|A ring with clean holes will ensure smooth flow of gas and fuller flame.

|Otherwise, the generated biogas can escape into the atmosphere through these cracks.

| Once in 3 years,  the mason also repaints the inner wall of the digester tank.

|This is done by using '''white cement''' and '''synthetic resin adhesive''' mixture.

|This mixture  will also help to seal the cracks, if present.

| To make this mixture, use the following- 2 liters of water,

| 250 gms of Synthetic Resin Adhesive and  2 kgs of white cement.

|  Let us summarize. In this tutorial, we learnt about different techniques to maintain and repair of the biogas plant and the biogas burner.
