Biogas and Internal Combustion Engines

04/16/2009 1:34 AM

I am a 4th year mechanical engineering student At Tribhubhan University, Institute of Engineering, Pulchowk Campus, Nepal. I would like to do project on Internal combustion Engine Running with Bio Gas. IS it good idea To pump water Using THe BIO GAs From Toilet OR It will BE more Costier THan Electricity OR it will NOt be technically POssible Please suggest me.............

It is done in larger municipal sewage works, to generate electricity that is both consumed within the works and exported to the local grid.

Biogas is also used for process heating within a sewage works. Surplus gas is sometimes simply burnt off at a waste gas burner. The surplus gas is the resource otherwise available for electrical generation for export. The economic viability of it depends upon the tariff agreed between the works and the local electricity utility company, and the price of investment capital.

Technically, it is possible. What you need is a biogas digester to ferment the wastes to produce the biogas. Whether it is feasible or not depends on how much wastes you have.

I believe that the GE product you are referring to is JENBACHER in Austria.

They have many engines operating on land-fill gas as well as 'clean' NG. Fermenter derived gas is an alternative to the other fuels but may need conditioning to achieve a stable calorific value.

Has anyone ever farted in an engine's air intake to see what happens? seriously...gas engines can be modified to run on natural gas (from the ground, that is) or propane. If you filled your tank with biogas, is there enough energy density to run an engine.

Try researching Wood Gas. You also might check out this web site AllPowerLabs.org

All power labs has designed a wonderful little wood gasifier that is built just for the bio gas researcher. And it is not limited to wood you can put anything that will burn in it.

And to answer your question is it possible yes. This type of fuel has been used for years.

Good luck with your research.

Waste Management Corporation in the USA is a leader in tapping methane from landfills. It is used in special large Caterpillar generators.

Biogas is a mixture of Carbon dioxide, Hydrogen and Methane; but the concentrations of the different gases varies with production process and raw material of the process. Obviously the removal of some of the carbon dioxide may be necessary but in general provided the concentration ratios are maintained then the biogas can be used consistently to produce stable power - both electrical and thermal.
