Natural gas/biogas generator set Rated power：130KW
Voltage frequency：400V/50Hz
Product introduction
The WL130-CNG series gas generator set is an automated generator set specially developed for natural gas and biogas by our company using advanced domestic and foreign technologies and integrating many years of market experience. This unit can meet the full-load power generation requirements of low-concentration biogas (CH4≥30%). After our rigorous engine structure upgrades and combustion technology development, this series of natural gas and biogas generator sets have the characteristics of high efficiency, low energy consumption, easy maintenance, and high reliability to meet customer needs.
Energy efficient
The unit adopts our company independently developed large excess air coefficient combustion organization technology and digital boost matching technology to ensure that the unit achieves lean combustion in the full power range and accurately controls the excess air coefficient ≥ 1.5. The engine adopts our gas composition adaptive technology, which can automatically adapt to natural gas and biogas of various concentrations and calorific values, enabling the engine to achieve rapid combustion, even operation of each cylinder, and improve power generation efficiency when using natural gas and biogas.
High reliability
The unit uses a stable and mature engine, which has been upgraded with our technology and replaced with specially developed engine cylinder liners, pistons, valves, camshafts and other easy-to-wear parts. This has overall improved the engine's high temperature resistance and corrosion resistance, significantly improving its performance of reliability.
Low operation and maintenance costs
All components of the unit have been verified through rigorous simulation tests and 8,000 hours of full-load field use. The oil consumption rate of the gas engine upgraded by our company has been greatly reduced, and the oil replacement interval is ≥1000h. The spare parts developed for the unit are all at market prices, and combined with the long maintenance cycle of the unit, maintenance costs are significantly reduced.
Security
The unit is equipped with a high-end monitoring and control system, equipped with single-cylinder temperature monitoring, single-cylinder exhaust temperature monitoring, and single-cylinder ignition angle adjustment to ensure stable operation of the unit in real time. The unit is equipped with explosion-proof valves, real-time water temperature and oil pressure monitoring, and gas leakage alarms to ensure the safety of the unit.
Alternator
Mature high-end generators in the unit supporting industry have the advantages of high power generation efficiency, low temperature rise, low waveform distortion rate, good dynamic performance, and stable AVR parallel operation. They have first-class reliability and durability and can meet the needs of various harsh environments. Requirements.
