Cow Dung Power Plant

06/09/2010 2:36 AM

Dear Fellow Engineers and Seniors,

If I wanted to set up a 1MW cow dung power plant.

Q1- What equipment would one use to set it up?

Q2- What would be the process flow of such a plant?

Q3- What would be the optimum heating value of the Biogas to operate an Engine or a Generator to produce 1MW of electricity?

Q4- How much gas would be need to produce 1MW?

Q5- How efficient would the Biogas Power Plant be?

I know I am asking a lot of questions, but I'm sorry, I'm new to the topic and information out there is quite scarce. There is also a lot of useless info which is quite de-moralizing. I hope that I will get a positive output from you Fellow Engineers.

Best Regards,

Knowledge Builder

DG EE

Everybody sing now!:

(It's a cultural thing; sorry if you haven't it before.)

First of all you need a lot of cows!

Anaerobic digestion process.

The heating value of the Biogas is what it is, optimum or not. Typical value is 24 MJ/m3.

Overall efficiency about 25%. I make that biogas input about 600 m3/h.

I estimate about 30000 people needed for that biogas flow. You need to convert that to cows. My guess is something like 24% = 7500.

Cheers.......Codey

In my area, a cows farm invest in a biogas plant, from 1800 cows ( adults with few hundreds babies cow) they got 550KW of electric power, in your case you need something like 4000 cows to produce 1MW

Cheers

In the late 1960s the erstwhile Punch magazine carried a cartoon that shows an Indian bullock cart zipping past cars on the road, with a couple of bulls nonchalantly munching fodder on the cart with a biogas engine. Bioramani

Hi DamnGudd,

In India we have many plants installed many years back. They are called "Gobar Gas Plants",just type these words in google and you will get many sites with detailed information.

Dear ...

Could you get the information. if so forward it to me. I am also looking for some such information. Hope you know you know that you require 5oo cows (its gober) to produce 100 kwh of electricity. Then you require 5000 cows to produce 1MW of electricity in a day, not 1 MW day.pl note.
