沼氣發(fā)電的優(yōu)勢(shì)

Advantages of biogas power generation

1、原料來(lái)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(chǎn)甲烷菌對(duì)有機(jī)物進(jìn)行厭氧消化而產(chǎn)生的。因此，只要有機(jī)物存在，在適宜的環(huán)境條件下，會(huì)產(chǎn)生甲烷。例如，人畜糞便、有機(jī)工業(yè)廢水、垃圾填埋場(chǎng)、農(nóng)作物秸稈等均可作為生產(chǎn)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(fā)電，我擔(dān)心總有會(huì)枯竭。

I am afraid that biogas will dry up one day.

3、蒸汽發(fā)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(jīng)過氣體預(yù)處理后，硫化物含量已降至低濃度，對(duì)環(huán)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(fā)電建設(shè)規(guī)模小，建設(shè)周期短

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

小型沼氣電站的建設(shè)可在數(shù)周或數(shù)月內(nèi)實(shí)現(xiàn)，并可根據(jù)需求發(fā)展隨時(shí)增擴(kuò)，有利于資金的回收和周轉(zhuǎn)。

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(fā)電機(jī)組如何發(fā)電

How to generate electricity for biogas generating set

1、沼氣脫硫穩(wěn)壓、防爆設(shè)備：發(fā)生器使用的沼氣必須先通過脫硫設(shè)備，以減少硫化氫對(duì)發(fā)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(jìn)氣調(diào)節(jié)系統(tǒng)：在進(jìn)氣歧管上應(yīng)設(shè)置一套靈活的氣體混合器，以調(diào)節(jié)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(fā)劑焚燒系統(tǒng)：沼氣焚燒速度慢，對(duì)原來(lái)使用汽油、柴油、天然氣的發(fā)電機(jī)焚燒系統(tǒng)進(jìn)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(xiàn)，延長(zhǎng)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(diào)速系統(tǒng)：如果沼氣發(fā)電機(jī)組獨(dú)立工作，即以電氣設(shè)備為負(fù)載工作，電氣設(shè)備的并入和卸載會(huì)導(dǎo)致發(fā)電機(jī)的負(fù)載增加。為了保證發(fā)電機(jī)組的正常運(yùn)行，沼氣發(fā)電機(jī)上的調(diào)速系統(tǒng)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(yù)熱應(yīng)用系統(tǒng)：利用預(yù)熱應(yīng)用設(shè)備，利用發(fā)動(dòng)機(jī)冷卻水和廢氣中的熱量，提高沼氣的動(dòng)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(fā)電機(jī)組并網(wǎng)控制系統(tǒng)：主要包括發(fā)電機(jī)電壓調(diào)節(jié)電路、自動(dòng)準(zhǔn)同步并列控制電路、手動(dòng)并列寬度和列控制電路、電路、氣體發(fā)生器啟動(dòng)及輔助設(shè)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.
