Ⅶ. Biogas Generator FAQ
Q1: Can the biogas produced by rural biogas digesters be directly used in a regular gas generator?
A: It's not recommended. The gas from rural biogas digesters contains more impurities and corrosive components, and regular generators don’t have anti-corrosion structures. Long-term use can lead to internal rust and unstable power supply. Specialized biogas generators, paired with a full set of purification equipment, are suitable for long-term operation with biogas sources.
 Q2: What equipment does a complete rural biogas generator system include?
A: The complete system consists of four main parts: biogas purification devices, biogas generator, waste heat recovery equipment, and distribution cabinets. The purification equipment is essential; without it, the equipment’s service life will be significantly shortened.
Q3: How should villages choose a suitable biogas generator?
A: Choose the generator based on the daily biogas output and the village’s total daily electricity usage. Villages with fluctuating gas production can use multiple generators to ensure basic electricity supply during maintenance. Technicians can provide free planning advice for suitable options.

Q4: Can the excess electricity generated by rural biogas generators be fed into the grid?
A: Our biogas generators support grid connection for excess electricity. We can provide full equipment testing and company qualification documents and cooperate with local power authorities for grid connection approval, along with technical guidance.
Q5: In villages with low winter temperatures, can biogas generators start normally?
A: For cold regions, models with preheating options are available. There are established cases of biogas projects in northern villages, and the generators can start and operate stably in low-temperature environments.
Q6: What does the warranty for rural biogas generators cover?
A: The equipment comes with a standard warranty, with extended coverage for core power components. Failures caused by manufacturer design or production defects can be repaired or replaced for free. Damage caused by excessive gas impurities, operational mistakes, or lack of timely maintenance is not covered under the free warranty.
