Natural gas-its main component is Ch4, which takes 90% of the whole content. The displacement of NOX, CHM and Co from burning are much lower than the state standards and without dust pollution; Thermal efficiency of conversion is 65%, which is same to the LPG and higher than Coal. Calculated on the same calorific value, the price of natural gas is lower than the price of coal and petroleum.
Requirements for natural gas:
1. The ratio of Ch4 in natural gas ≥70%;
2. Pressure of natural gas 80-200kpa, rate of pressure change ≤1kpa/min
4. Moisture content ≤40g/m3;
5. Impurity particle size ≤5μm, Impurity content ≤30mg/Nm3.
If fuel gas contains higher quantity of sulfur and ammonia, it not only corrodes the pole of spark plug seriously, but also increases the acid value,which corrodes internal parts of generator set and corrodes the generator set with precipitates.
EXON gas Genset feather:
1. use CUMMINS NGV engine, advanced structural innovation (water/oil cooled turbocharger technology, low friction technology, corrosion-resistant valve technology, compression ratio optimization, electrical cabinet integrated, institutional and more compact, lower cost, easy maintenance);
2. advanced control technology (with EXON control system, to achieve low-pressure combustion, lean burn, high-energy ignition, advanced closed-loop control, adaptive transient, fully functional start,EOBD);
3. low exhaust temperature, long life;
4. free switching function of Genset from 50HZ↔60HZ, is possessed of stronger applicability and generality. Reduce the cost;
5. can use a potentiometer to adjust the target speed;
6. our air-fuel ratio control system developed for real-time feedback via the lights. From the light color, brightness, on-off get real-time air-fuel ratio operating range. To provide a good reference for the running state of the engine;
7. a wide range of the gas;
8. high economic;
9. flexible maintenance;
10. high emission;
11. all-electronic intelligent control, high automation level.
