In fact, there are two types of biogas generating units, one is a single fuel biogas generating unit that uses biogas completely, and the other is a dual fuel biogas diesel that uses biogas partially
Working principle of single fuel biogas generator unit: compress the mixture of “air biogas” in the cylinder, burn it with spark plug, get power through reciprocating motion of piston, and then connect the generator to generate power. It has the following advantages:
1. Auxiliary fuel oil and its supply equipment are not required
2. The fuel is a system, which is simpler in control than the generator set that can burn two kinds of fuel
3. The price of generator set is low
Working principle of dual fuel biogas diesel generator set: compress the mixture of “air combustion gas” in the cylinder, burn it with ignition fuel, get power through reciprocating motion of the piston, and then connect the generator to generate power. It has the following advantages:
1. It can work with liquid fuel or gas fuel
2. It can adapt to the change of biogas production and methane concentration
3. If the gas fuel is changed to diesel fuel and the operation is stopped, there is no unburned gas left in the generator set because of its corrosion resistance
