There are many high-altitude areas in the central and western regions, including the vast areas of China, Tibet, Qinghai, Yunnan, Guizhou, Sichuan and other places. In remote areas of these areas, autonomous regions, power load centers are often difficult to reach and must therefore be purchased as common feeder lines.
People who live in relatively thin oxygen plains, people with altitude sickness, because of the general air in high altitude plateau areas, performance usually mild headache, insomnia, mild chest tightness and other overexcited. Using a diesel generator, will it affect the working principle of the diesel generator set using the environment plateau to convert energy into diesel combustion?
Due to the thin low air pressure at high altitude, the air, oxygen-containing components below the diesel generator set is the original diesel generator can not emit sufficient suction air volume for the low temperature of the diesel generator and the combustion environment, the predetermined rated power, Because of the lowering of diesel generators.
The power of various diesel generator sets operating on the plateau is different. When using the generator to increase the marked kilometer, due to the reduction of the supercharger to about 6-1O% of the non-power driven supercharger, – the reduced supply 0x9A9A should be plateaued for long-term use at the appropriate altitude, then the oil amount.
Considering the tendency to smoke at high altitudes, it is usually good to have a naturally aspirated diesel engine pre-tilt sufficiently in advance for the economy of running the diesel engine.
Experiments have shown that this method can be used as a plateau power compensation for exhaust turbochargers when using diesel engines in plateau areas. Exhaust turbocharger power not only improves plateau compensation, smoke color, power recovery function and lower fuel consumption.
The ambient temperature increases with the altitude usually the angle increases by 1000M, because it increases the ambient temperature diesel generator power in high altitude air Therefore, the function is less than about 0.6 degrees to remove the general area to start the diesel engine range, it is more than the normal area This sucks. When the user uses it, the auxiliary start method corresponding to the cold start must be adopted.
The pressure of the cooling air is much lower than that of the cooling system because of the high heat dissipation mass and the increase in the normal cooling conditions of the unit, while reducing the boiling point of water in the cooling air per kWh. Should not be commonly used in open refrigeration cycles at high altitudes, it can be used to increase the boiling point of the coolant in closed cooling systems used during pressure platens.
In order to improve the economical operation of diesel generators considering the ignition tendency and high altitude conditions, generally the fuel supply advance angle of non-turbocharged diesel engines should be sufficiently advanced, it is recommended.
All these factors should be taken into account when considering the purchase, plant environment, harsh weather conditions and the choice of diesel generator set resistance at high altitudes to use this equipment.
