600KW Biomass Genetator
This biomass gas generator set adopts 12V190ZL engine, which is one sort of highly intelligent,low heat consumption, high reliability, low emission, especially designed for biomass gas with high contents of hydrogen.
1.Specially design
Engine 12V190ZL is specially designed for low heat value gas with one-button start function.
2. Precise control of air-fuel ratio
It can realize the air-fuel ratio control algorithm based on the high-speed controller with imported air-fuel ratio control actuators. The air-fuel ratio control is precise and the adjustment speed is fast. The engine automatically monitors the combustion status in real time and the central control unit issues instructions to adjust the gas channel, thereby changing the gas intake, and automatically adjusting the mixing ratio. Through this technology, the temperature of the cylinder of the unit can be controlled below 400℃,which significantly reduces the heat load and significantly improves the reliability of the operation of the unit, especially to prevent knockig.
3. High-energy digital ignition system
Using German Motor-tech high-energy digital ignition system, real-time adjustment of ignition advance angle can be realized to prevent knocking and high-temperature in cylinder, which can ensure the safe operation of the generator set.
4. Centralized control of gensets
Through centralized control, digital collecting generator sets feedback signals and adjust the air-fuel ratio automatically. It can reduce manual operation work load and avoid mis-operation during starting.
5. Measurement protection
All parameters such as cylinder temperature and exhaust temperature can be measured and the
engine protection is complete.
6. Automatic grid connection
Automatically match the phase, adjust the frequency and voltage, and realize the direct grid connection function of power generation.
