Preparation of Gas Holder Tank

The 500 liter capacity tank is required to be cut at the top. The visible top ridge will be used as guideline to cut the tank

Using a sharp knife make a slot along the line
Now you can insert a hacksaw blade in the slot and cut along the ridge
The hacksaw blade gets very hot. Wrap the end with a piece of cloth
Cut through the ridge and remove the top cut portion from the tank

Preparation of Digester Tank


The top portion of the digester tank also needs to be cut and removed. However, the width of cutting should be just enough for the free movement of gas tank

*Place the removed top portion of gas holder on top of digester tank

*Leave about 20 mm on all sides and mark the guide line for cutting

*Using a hacksaw, cut slots on top of projected portion of digester tank

*Now use a hacksaw blade to cut along the guide line and remove the top

*Finish the cut edges with sandpaper

Questions will be gladly entertained. Keep them rolling in.

Fixing the Feed Pipe to the Digester Tank


The 120 mm dia door elbow need to be fixed at the bottom of the digester tank

*Place the elbow and mark the cutting line

*Make a slot along the line with a sharp knife

*Insert the hacksaw blade in the slot and cut along the guide line

*Insert the Elbow in place

*Seal with M-seal epoxy compound on both outer and inner sides of the tank

Hi fellow Nlanders, For the complete tutorial on how to build your BIOGAS GEN., Pls kindly visit https://www.nairaland.com/2784884/make-ngn1999-daily-tru-biogas

Merry Christmas to you fellow Nairalanders.

Happy new year

[size=15pt]Class will commence soon. Pls be prepared.[/size]

pls I am joining the class also

Have taken a seat

We are waiting

The production of biogas by armatures should be discouraged as the methane gas that evolves is highly volatile and inflammable. Ordinary household cooking gas need be carefully managed talkless of biogas

Organic matter? Is that poo poo?

Bubu isn't interested in this. He just allocated some money for oil exploration in NE instead of looking for alternative source of energy.

Present btw

[size=15pt]Fixing Slurry Outlet Pipe With The Digester Tank[/size]

The 50 mm dia 300 mm long pipe is to be fitted at the top of digester for the slurry outlet

Place the pipe on top portion of digester tank opposite to the feed pipe

Mark the cutting line

Using a sharp knife cut along the guide line and remove the cut piece

Insert the slurry outlet pipe and seal with M-seal epoxy compound from both sides of the tank

You can cut and remove the extra projection inside tank if required. Otherwise leave as it is

[size=15pt]Fixing The Guides Over Digester for the Movement of Gas Holder Tank[/size]

Some sort of guides are to be provided for the easy up-and-down movement of gas holder tank. We will use the 250 mm long 32 mm dia pipes for this.There are six projected portions on top of the digester. The slurry outlet pipe and waste input pipe are in alignment with two them opposite to each other. Leaving these two we will fix 32 mm pipes on other four projections. These pipes will be extended after placing the gas holder tank.

Place the 32 mm dia pipe on top of projections and make a mark

Using a hacksaw cut and remove a square portion of the marked area.

Insert 32 mm dia pipes on all these cut portions and fix with M-seal epoxy compound

After the compound is cured cut and remove excess leaving about 25 mm projection

[size=15pt]Providing Guide Support on the Gas Holder Tank[/size]

As we have seen in the previous steps, 4 numbers of 32 mm dia guide pipes have been provided on top of the digester. In order to keep the gas holder tank in alignment, we will provide a sort of guide system on the sides of the gas tanks. Here we can use the 40 mm dia threaded couplers for this. Fix only two numbers opposite to each other. We can fix the other two once we place gas tank inside the digester and observing the movement of gas holder.

[size=15pt]Preparation of Gas Pipes[/size]

I spent one full afternoon in shopping and preparing the Gas pipes. There will be three sets of gas pipes as below.

From Gas Holder tank to the Link Pipe mounted on wall

Link pipe between gas holder tank pipe and kitchen

From the link pipe to Biogas stove

Parts required

Three pieces of gas pipes, all about 2.5 meters long

Ball valve 2 numbers one with gas outlet on gas tank and another with the end of link pipe

Bend 1 number over the gas tank

Nipple 1 number over gas tank

Adapter 1 number inside gas tank connecting nipple with the bend

Three numbers of barbs with male threaded ends crimped with clips at one end of pipes

Two numbers of barbs with female ends crimped with clips at other end of pipes (One end of the pipe is left free as this will connect with the stove)

Inner and outer washers

One roll of teflon tape

Few 12 mm size U-clamps for fixing the link pipe on the wall

At the shop itself I have measured all the pipes and used their hand-crimping tool to crimp all the ends of pipes. The pipes are tested for leakage by fixing the closed ball valve at each end separately, immersed in water and blowing air from the other end.
