1，沼气脱硫及稳压、防爆设备：供发起机运用的沼气要先通过脱硫设备，以削减硫化氢对发起机的腐蚀。沼气进气管路上设备稳压设备，以便于对流量进行调整，到达较佳的空燃比。别的，为避免进气管回火，应在沼气总管上安顿防回火与防爆设备。

　　1. Methane desulfurization, 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 adjust the flow rate and achieve a better air-fuel ratio. In addition, to avoid backfire in the intake pipe, anti backfire and explosion-proof equipment should be installed on the biogas main pipe.

　　2，进气调整体系：在进气总管上，需设置一套准确、活络的燃气混合器，以调理空气和沼气的混合份额。

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

　　3，发起机焚烧体系：沼气的焚烧速度慢，关于本来运用汽油、柴油已及天然气的发起机的焚烧体系要进行必定程度的改造，以进步焚烧功率，削减后焚烧表象，延伸工作寿数。

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

　　4，调速体系：若沼气发电机组独立工作，即以用电设备为负荷进行工作，用电设备的并入和卸载都会使发电机的负荷发生动摇。为了保证发电机组正常工作，沼气发起机上的调速体系必不可少。

　　4. Speed regulation system: If the biogas generator unit operates independently, that is, working 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，预热运用体系：选用预热运用设备，对发起机冷却水和排气中的热量进行运用，进步沼气的动力运用功率。

　　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，并网控制体系：首要包含发电机调压电路，主动准同期并排控制电路，手动并排宽和列控制电路，丈量电路，燃气发起机及辅佐设备控制电路等。

　　6. Grid connected 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.
