1200KW Baudouin Biogas CHP Biogas Electricity Generator
Technical Specification
Gas Generators
Weichai 16M33D1280NG gas engines and mecc alte ECO46 alternators are selected. In one canopy, one 1.2MW gas generator, one horizontal cooling system and one control system are integrated. The canopy is sand and catkin proof. The temperature zone control design enables the generator be normally operated at temperature range -30℃ to 50℃.
Total power plant capacity is 12MW and all generators are combined. Any of the generators can be backup set which enables urgent shift of any other generator. An isolate switch is installed for each of the generator which will isolate any gas generator when necessary.
Generator Model: EW-1200NGB-1/4A.
1.2MW Gas Generator Design
Canopy
The 30-feet long canopy is exclusively designed for the 1.2MW generator. The surface is coated by polyurethane which is shining and wear-resisting. In the canopy, there are control cabinet, generator cabin, air inlet/outlet filtering system. On the top of the canopy, there is horizontal cooling system. Gas supply is set at one end and power cable is connected from another end. This layout makes site gas pipe and cable arrangement easy and convenient.
Gas Engine
Baudouin 16M33D1289NG gas engine is selected. The gas engine is deeply developed in fuel control systems to improve its electric efficiency, reliability and fuel adaptivity for certain working conditions. The development also give consideration for dynamic responsiveness, fuel economy, reliability and safety.
Proven gas engine is controlled by imported gas close-loop lean-burn control system which includes latest Woodward control system, Hoerbiger intelligent ignition system, ABB high efficient turbocharger, single cylinder in-dependant compactive ignition, electrical speed regulating system, fuel close-loop control system, environment self-adaptation system and self diagnose and protection system. All these systems will ensure accurate and reliable control of gas engine and ensure its economic, dynamic and environmental performances. The systems are also optimized by our company to achieve high reliability and efficiency.
Cooling System
High-low temperature horizontal cooling system, high efficient, low power electrical fans, inter-cooler and jacket water cooling capacity close-cycle control are equipped to enable the generator being used in different ambient temperature.

Fume Nox contends ≤500ppm； | ||
The gas generators are started by 24V DC battery. No other diesel generator or grid power supply needed.
There are manual emergent stop and automatic failure emergency stop in the cases of natural gas leakage, overcurrent etc.
One-button control, air-fuel ratio auto adjustment, power factor auto control, automatic load increase and decrease can be realized on the generator.
Generator Control System: The control cabinet has one displayer. In the cabinet, there are controllers, relays, fuses, meters, adjusting buttons, indicators and emergent stop button to monitor and control the generator’s working process.
The control system has protection functions and sound/light alarmings for over load, over current, short circuit, reverse power, underfrequency, overfrequency, undervoltage, overvoltage, over speed etc.
For slight failures like high temperature of cooling water, low pressure of lubricant, over load, fail startup, there will be light and sound alarming and auto or manual stop is allowed.
For severe failure like high temperature of engine, low lubricant pressure, over speed etc, it will stop automatically and alarming will be sent out.
