在廣袤的農(nóng)村大地上，每年秋收后都會產(chǎn)生大量的農(nóng)作物秸稈。過去，這些秸稈往往被隨意丟棄或露天焚燒，不僅造成了嚴重的資源浪費，還帶來了空氣污染等環(huán)境問題。秸稈氣發(fā)電機組的出現(xiàn)，為農(nóng)業(yè)廢棄物的資源化利用開辟了一條嶄新的道路，讓廢棄的秸稈煥發(fā)出綠色的生機。

On the vast rural land, a large amount of crop straw is produced every autumn harvest. In the past, these straw were often discarded or burned in the open air, which not only caused serious resource waste, but also brought environmental problems such as air pollution. The emergence of straw gas power generation units has opened up a new path for the resource utilization of agricultural waste, allowing waste straw to radiate green vitality.

秸稈氣發(fā)電機組的工作原理基于生物質(zhì)氣化技術(shù)。秸稈、稻殼、木屑等生物質(zhì)在發(fā)生爐中，經(jīng)氧化還原反應(yīng)生成秸稈氣。這種氣體的主要可燃成分是一氧化碳（CO）和氫氣（H2），另外含有少量的甲烷（CH4）等。然而，剛產(chǎn)出的秸稈氣中含有大量的焦油、水分和一定的灰份，這些物質(zhì)對燃氣發(fā)動機運行極為不利。因此，秸稈氣在進入發(fā)電機組前，必須進行嚴格的預(yù)處理，通過過濾、冷卻、洗滌等工藝，去除雜質(zhì)和焦油，確保氣體的純凈度。

The working principle of straw gas generator set is based on biomass gasification technology. Biomass such as straw, rice husk, and sawdust undergo oxidation-reduction reactions in the reactor to generate straw gas. The main combustible components of this gas are carbon monoxide (CO) and hydrogen (H2), with a small amount of methane (CH4). However, the newly produced straw gas contains a large amount of tar, moisture, and a certain amount of ash, which are extremely detrimental to the operation of gas engines. Therefore, before entering the power generation unit, straw gas must undergo strict pretreatment through processes such as filtration, cooling, and washing to remove impurities and tar, ensuring the purity of the gas.

在發(fā)電環(huán)節(jié)，秸稈氣發(fā)電機組展現(xiàn)出了高度的靈活性和適應(yīng)性。小功率機組通常采用比例混合器，在0~100%負荷下只需做簡單的空氣進量調(diào)節(jié)；而大功率機組則采用轉(zhuǎn)速功率閉環(huán)混合稀薄燃燒控制系統(tǒng)，大大提高了可燃氣體的利用率，減少了秸稈氣的消耗量，同時降低了運行成本和尾氣NOx的排放。秸稈氣發(fā)電機組不僅解決了農(nóng)業(yè)廢棄物處理難題，還為農(nóng)村地區(qū)提供了清潔、穩(wěn)定的電力供應(yīng)，實現(xiàn)了經(jīng)濟效益、社會效益和環(huán)境效益的統(tǒng)一，是推動鄉(xiāng)村振興和綠色農(nóng)業(yè)發(fā)展的重要力量。

In the power generation process, straw gas generators have demonstrated high flexibility and adaptability. Small power units usually use a proportional mixer, which only requires simple air intake adjustment under 0~100% load; The high-power unit adopts a speed power closed-loop hybrid lean combustion control system, which greatly improves the utilization rate of combustible gases, reduces the consumption of straw gas, and reduces operating costs and exhaust NOx emissions. The straw gas generator not only solves the problem of agricultural waste disposal, but also provides clean and stable power supply for rural areas, achieving the unity of economic, social and environmental benefits. It is an important force in promoting rural revitalization and green agriculture development.
