沼气发电的优势

Advantages of biogas power generation

1、原料来源广泛

1. Wide range of raw materials

沼气的主要燃烧成分是甲烷，它是由产甲烷菌对有机物进行厌氧消化而产生的。因此，只要有机物存在，在适宜的环境条件下，会产生甲烷。例如，人畜粪便、有机工业废水、垃圾填埋场、农作物秸秆等均可作为生产沼气的原料。

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.天然气是可再生能源

2. natural gas is renewable energy

用沼气发电，我担心总有会枯竭。

I am afraid that biogas will dry up one day.

3、蒸汽发电清洁、染色少

3. Steam power generation is clean and less dyed

沼气中含有少量硫化物，经过气体预处理后，硫化物含量已降至低浓度，对环境基本有影响。

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、蒸汽发电建设规模小，建设周期短

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

小型沼气电站的建设可在数周或数月内实现，并可根据需求发展随时增扩，有利于资金的回收和周转。

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.

沼气发电机组如何发电

How to generate electricity for biogas generating set

1、沼气脱硫稳压、防爆设备：发生器使用的沼气必须先通过脱硫设备，以减少硫化氢对发生器的腐蚀。

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、进气调节系统：在进气歧管上应设置一套灵活的气体混合器，以调节空气与沼气的混合比。

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、引发剂焚烧系统：沼气焚烧速度慢，对原来使用汽油、柴油、天然气的发电机焚烧系统进行一定的改造。它的制造是为了提高燃烧效率，减少后焚烧的出现，延长使用寿命。

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、调速系统：如果沼气发电机组独立工作，即以电气设备为负载工作，电气设备的并入和卸载会导致发电机的负载增加。为了保证发电机组的正常运行，沼气发电机上的调速系统是必不可少的。

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、预热应用系统：利用预热应用设备，利用发动机冷却水和废气中的热量，提高沼气的动力利用率。

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、沼气发电机组并网控制系统：主要包括发电机电压调节电路、自动准同步并列控制电路、手动并列宽度和列控制电路、电路、气体发生器启动及辅助设备控制电路等。

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.
