B3 - Using Biogas Generators Flashcards
What happens during a continuous biogas generator?
Large batches are continuously made at a steady rate.
What must a biogas generator have? [3]
1) an inlet for waste.
2) an outlet for waste.
3) an outlet for biogas.
Which biogas generator, batch or continuous, will cost more and why?
The continuous generator because it requires mechanical pumping.
Which biogas generator, batch or continuous, is less convenient and why?
The batch generator because it must be continually loaded, emptied and cleaned.
How do you maintain a biogas generators efficiency? [2]
1) by keeping it at 35c using insulators or solar heaters.
2) by ensuring there are no leaks.
Where must biogas generators be positioned and why?
Away from houses & close to the material source due to the smell.
Why are biofuels good? [6]
1) carbon neutral.
2) no acid rain.
3) no waste lying around so no methane.
4) cheap & readily available.
5) the output ease is a better fertiliser.
6) acts as waste disposal.
What happens during a batch biogas generator?
Small batches are manually loaded.
