沼氣發電的優勢

Advantages of biogas power generation

1、原料來源廣泛

1. Wide range of raw materials

沼氣的主要燃燒成分是甲烷，它是由產甲烷菌對有機物進行厭氧消化而產生的。因此，只要有機物存在，在適宜的環境條件下，會產生甲烷。例如，人畜糞便、有機工業廢水、垃圾填埋場、農作物秸稈等均可作為生產沼氣的原料。

The main combustion component of biogas is methane, which is produced by anaerobic digestion of organic matter by methanogens. Therefore, as long as organic matter exists, methane will be produced under appropriate environmental conditions. For example, human and animal excrement, organic industrial wastewater, landfill, crop straw, etc. can be used as raw materials for biogas production.

2.天然氣是可再生能源

2. natural gas is renewable energy

用沼氣發電，我擔心總有會枯竭。

I am afraid that biogas will dry up one day.

3、蒸汽發電清潔、染色少

3. Steam power generation is clean and less dyed

沼氣中含有少量硫化物，經過氣體預處理后，硫化物含量已降至低濃度，對環境基本有影響。

Methane contains a small amount of sulfide. After gas pretreatment, the sulfide content has been reduced to a low concentration, which basically has an impact on the environment.

4、蒸汽發電建設規模小，建設周期短

4. Small scale and short construction period of steam power generation

小型沼氣電站的建設可在數周或數月內實現，并可根據需求發展隨時增擴，有利于資金的回收和周轉。

The construction of small-scale biogas power stations can be realized within weeks or months, and can be expanded at any time according to demand, which is conducive to the recovery and turnover of funds.

沼氣發電機組如何發電

How to generate electricity for biogas generating set

1、沼氣脫硫穩壓、防爆設備：發生器使用的沼氣必須先通過脫硫設備，以減少硫化氫對發生器的腐蝕。

1. Biogas desulfurization, pressure stabilization and explosion-proof equipment: the biogas used by the generator must first pass through the desulfurization equipment to reduce the corrosion of hydrogen sulfide to the generator.

2、進氣調節系統：在進氣歧管上應設置一套靈活的氣體混合器，以調節空氣與沼氣的混合比。

2. Intake air conditioning system: a set of flexible gas mixer shall be set on the intake manifold to adjust the mixing ratio of air and biogas.

3、引發劑焚燒系統：沼氣焚燒速度慢，對原來使用汽油、柴油、天然氣的發電機焚燒系統進行一定的改造。它的制造是為了提高燃燒效率，減少后焚燒的出現，延長使用壽命。

3. Initiator incineration system: the biogas incineration speed is slow. The original generator incineration system using gasoline, diesel and natural gas shall be modified to some extent. It is manufactured to improve the combustion efficiency, reduce the occurrence of post incineration and prolong the service life.

4、調速系統：如果沼氣發電機組獨立工作，即以電氣設備為負載工作，電氣設備的并入和卸載會導致發電機的負載增加。為了保證發電機組的正常運行，沼氣發電機上的調速系統是必不可少的。

4. Speed regulation system: if the biogas generator unit works independently, i.e. takes the electrical equipment as the load, the incorporation and unloading of the electrical equipment will lead to the increase of the load of the generator. In order to ensure the normal operation of the generator set, the speed regulation system on the biogas generator is essential.

5、預熱應用系統：利用預熱應用設備，利用發動機冷卻水和廢氣中的熱量，提高沼氣的動力利用率。

5. Preheating application system: use the preheating application equipment and the heat in the engine cooling water and exhaust gas to improve the power utilization rate of biogas.

6、沼氣發電機組并網控制系統：主要包括發電機電壓調節電路、自動準同步并列控制電路、手動并列寬度和列控制電路、電路、氣體發生器啟動及輔助設備控制電路等。

6. The grid connection control system of biogas generator unit mainly includes generator voltage regulation circuit, automatic quasi synchronous parallel control circuit, manual parallel width and column control circuit, circuit, gas generator startup and auxiliary equipment control circuit, etc.
