廠家解析沼氣發(fā)電組成部分及發(fā)酵技術(shù)，沼氣發(fā)電體系對(duì)電能的最經(jīng)濟(jì)運(yùn)用方法是先滿意建設(shè)單位本身的用點(diǎn)需要，然后再將剩余的電力并入公共電網(wǎng)；發(fā)生的熱能也是先滿意發(fā)酵池的所需，然后再思考居處、農(nóng)場(chǎng)的取暖或運(yùn)送至共用供熱網(wǎng)。

The manufacturer analyzes the components and fermentation technology of biogas power generation. The most economical way to use biogas power generation system for electricity is to first satisfy the usage needs of the construction unit itself, and then integrate the remaining electricity into the public power grid; The generated heat energy is also satisfied with the needs of the fermentation tank first, and then the heating of the residence and farm or transportation to the shared heating network is considered.

一、沼氣脫硫及穩(wěn)壓、防爆設(shè)備：供發(fā)起機(jī)運(yùn)用的沼氣要先通過(guò)脫硫設(shè)備，以削減硫化氫對(duì)發(fā)起機(jī)的腐蝕。沼氣進(jìn)氣管路上設(shè)備穩(wěn)壓設(shè)備，以便于對(duì)流量進(jìn)行調(diào)理，到達(dá)最佳的空燃比。別的，為避免進(jìn)氣管回火，應(yīng)在沼氣總管上安頓防回火與防爆設(shè)備。

1、 Biogas 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. Pressure stabilizing equipment is installed on the biogas inlet pipeline to regulate the flow rate and achieve the optimal air-fuel ratio. Additionally, to prevent backfire in the intake pipe, anti backfire and explosion-proof equipment should be installed on the biogas main pipe.

二、進(jìn)氣調(diào)理體系：在進(jìn)氣總管上，需設(shè)置一套準(zhǔn)確、活絡(luò)的燃?xì)饣旌掀?，以調(diào)理空氣和沼氣的混合份額。

2、 Inlet conditioning system: An accurate and flexible gas mixer should be installed on the inlet manifold to regulate the mixing ratio of air and biogas.

三、發(fā)起機(jī)焚燒體系：沼氣的焚燒速度慢，關(guān)于本來(lái)運(yùn)用柴油、柴油已及天然氣的發(fā)起機(jī)的焚燒體系要進(jìn)行必定程燃?xì)獍l(fā)電機(jī)組度的改造，以進(jìn)步焚燒功率，削減后焚燒表象，延伸工作運(yùn)行壽數(shù)。

3、 Initiator incineration system: The incineration speed of biogas is slow. Regarding the incineration system of the initiator that originally used diesel, diesel, and natural gas, it is necessary to carry out a certain degree of transformation of the gas generator unit to improve the incineration power, reduce the appearance of post incineration, and extend the working life.

四、調(diào)速體系：若沼氣發(fā)電機(jī)組獨(dú)立工作運(yùn)行，即以用電設(shè)備為負(fù)荷進(jìn)行工作運(yùn)行，用電設(shè)備的并入和卸載都會(huì)使發(fā)電機(jī)的負(fù)荷發(fā)生動(dòng)搖。為了保證發(fā)電機(jī)組正常工作運(yùn)行，沼氣發(fā)起機(jī)上的調(diào)速體系必不可少。

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

五、預(yù)熱運(yùn)用體系：選用預(yù)熱運(yùn)用設(shè)備，對(duì)發(fā)起機(jī)冷卻水和排氣中的熱量進(jìn)行運(yùn)用，進(jìn)步沼氣的動(dòng)力運(yùn)用功率。

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

六、并網(wǎng)控制體系：首要包含發(fā)電機(jī)調(diào)壓電路，主動(dòng)準(zhǔn)同期并排控制電路，手動(dòng)并排寬和列控制電路，丈量電路，燃?xì)獍l(fā)起機(jī)及輔佐設(shè)備控制電路等。

6、 Grid connected control system: primarily includes generator voltage regulation circuit, active quasi synchronous parallel control circuit, manual parallel width and column control circuit, measurement circuit, gas generator and auxiliary equipment control circuit, etc.
