　　煤制煤氣發電機組 COAL GAS GENERATOR

　　氣體概述：Coal gas general description:

　　煤氣是以煤為原料加工制得的含有可燃組分的氣體。根據加工方法、煤氣性質和用途分為： 水煤氣 、半水煤氣、空氣煤氣 （或稱發生爐煤氣） 。

　　Coal gas is produced by coal with combustible components. The gas can be divided into: water gas, semi-water gas, air gas (or gasified coal gas) on base of production method,coal type and its functions.

　　煤制煤氣主要成分：Coal gas main component:

　　單段爐 Single stage gasifier

　　主要成分為H2（7%~10%）、CO（23%~27%）、CH4（1.5%~3%）、N2(48%~54%)、CO2（6%~8%)另外還含有少量的H2S、O2。

　　Main component: （7%~10%）、CO（23%~27%）、CH4（1.5%~3%）、N2(48%~54%)、CO2（6%~8%) and bits of H2S、O2

　　雙段爐 Double stage gasifier

　　主要成分為H2（11%~15%）、CO（27%~31%）、CH4（1.5%~3%）、N2(46%~52%)、CO2（3%~5%)，另外還含有少量的H2S、O2.

　　300系列煤制煤氣發電機組的優勢：Advantages of 300 series gas generator

　　1.300系列燃氣發電機組具有缸徑大、行程長、排量大的優點，適應低熱值氣體，能夠確保機組輸出功率持續恒定。

　　2.300系列機組采用內混式進氣系統及空燃比自動控制系統，徹底避免了高氫燃氣回火放炮問題。阻絕回火，確保燃氣輸送安全。

　　3.自然吸氣，確保燃氣輸送安全，氣源的壓力只需大于 2kPa 即可，使燃氣機組的適用范圍更廣，對燃氣中焦油的適用性強，氣源低壓輸送更安全。自吸式進氣，氣體混合后直接進入燃燒室，不需要渦輪增壓器、中冷器等進氣環節，部件少，自然減少了故障率。

　　4.300系列燃氣機組點火系統采用美國或德國進口等點火系統，保證點火受控，確保獲得高的點火能量和精確的點火時間，使做功更徹底，能量更大，爆發力更強。

　　5.可拆卸進氣閥箱，不需拆卸缸蓋即可方便維護進氣閥，清理焦油。

　　6.低轉速確保機組使用壽命，保證年運行8000h,大修周期60000h。

　　7.機組可以手動、自動并機并網功能亦可孤島運行，可實現遠程監控及操作等功能。

　　1. 300 series gas generator’s main features are wide cylinder diameter, long stroke and large displacement, to ensure its continuous and steady power output.

　　2. 300 series adopts internal gas and air mixture system and gas & air ratio automatic control system to avoid back-fire and explosion that may caused by high content of hydrogen. No back-fire to ensure gas delivery safety.

　　3. Naturally gas intake gives high safety to gas delivery. The generator requires gas pressure only over 2kpa, which let the generator applied in a wilder range and more adaptive to the tars in gas. Gas intakes naturally, then after mixed with air,entered into burner directly, without going through turbo charger,inter cooler etc, less sections, less breakdowns.

　　4. 300 series adopts ignition system imported form USA and Germany to make sure the ignition controllable, to get high ignition power and accurate ignition time. By which, the ignition operation is more complete, more strong and with more explosive power.

　　5. Intake gas valve box can be demounted without moving cylinder head section. It is more convenient for maintenance and tar clearance.

　　6. Low speed,long life span. It runs 8000horus/year and overhaul circle is around 60,000hours.

　　7. Generator sets can parallel with other generator sets and parallel to gird manually and automatically. It can also run on iceberg model or even monitored remotely.
