1. Methane desulfurization, pressure stabilization, and explosion-proof equipment: The biogas used for the initiator must first pass through the desulfurization equipment to reduce the corrosion of hydrogen sulfide on the initiator. A pressure stabilizing device is installed on the biogas intake pipeline to facilitate flow adjustment and achieve a better air fuel ratio. Additionally, to avoid backfire in the intake pipe, anti backfire and explosion-proof equipment should be installed on the biogas main pipe.

2，進氣調整體系：在進氣總管上，需設置一套準確、活絡的燃氣混合器，以調理空氣和沼氣的混合份額。

2. Intake adjustment system: An accurate and flexible gas mixer needs to be installed on the intake manifold to regulate the mixing proportion of air and biogas.

3，發起機焚燒體系：沼氣的焚燒速度慢，關于本來運用汽油、柴油已及天然氣的發起機的焚燒體系要進行必定程度的改造，以進步焚燒功率，削減后焚燒表象，延伸工作壽數。

3. Incineration system of initiators: The incineration speed of biogas is slow. The incineration system of initiators that originally used gasoline, diesel, and natural gas needs to be modified to a certain extent to improve incineration power, reduce the appearance of post incineration, and extend working life.

4，調速體系：若沼氣發電機組獨立工作，即以用電設備為負荷進行工作，用電設備的并入和卸載都會使發電機的負荷發生動搖。為了保證發電機組正常工作，沼氣發起機上的調速體系必不可少。

4. Speed regulation system: If the biogas generator unit operates independently, that is, with the electrical equipment as the load, the integration and unloading of the electrical equipment will cause the load of the generator to fluctuate. In order to ensure the normal operation of the generator set, the speed control system on the biogas generator is essential.

5，預熱運用體系：選用預熱運用設備，對發起機冷卻水和排氣中的熱量進行運用，進步沼氣的動力運用功率。

5. Preheating application system: Select preheating application equipment to apply the heat in the cooling water and exhaust of the initiator, and improve the power utilization of biogas.

6，并網控制體系：首要包含發電機調壓電路，主動準同期并排控制電路，手動并排寬和列控制電路，丈量電路，燃氣發起機及輔佐設備控制電路等。

6. Grid connection control system: It mainly includes generator voltage regulation circuit, active quasi synchronous parallel control circuit, manual parallel width and column control circuit, measurement circuit, gas initiator and auxiliary equipment control circuit, etc.
