1、農(nóng)作物秸稈量大，覆蓋面廣，燃料來(lái)源充足。2、秸稈含硫量很低。國(guó)際能源機(jī)構(gòu)的有關(guān)研究表明，秸稈的平均含硫量只有千分之3.8，而煤的平均含硫量約達(dá)百分之一。且低溫燃燒產(chǎn)生的氮氧化物較少，所以除塵后的煙氣不進(jìn)行脫硫，煙氣可直接通過(guò)煙囪排入大氣。丹麥等國(guó)家的運(yùn)行試驗(yàn)表明秸稈鍋爐經(jīng)除塵后的煙氣不加其他凈化措施完全能夠滿足環(huán)保要求。所以秸稈發(fā)電不僅具有較好的經(jīng)濟(jì)效益，還有良好的生態(tài)效益和社會(huì)效益。3、各類作物秸稈發(fā)熱量略有區(qū)別，但經(jīng)測(cè)定，秸稈熱值約為15000KJ/Kg，相當(dāng)于標(biāo)準(zhǔn)煤的50%。其中麥秸稈、玉米秸稈的發(fā)熱量在農(nóng)作物秸稈中為最小，低位發(fā)熱量也有14.4MJ/kg，相當(dāng)0.492kg標(biāo)準(zhǔn)煤。使用秸稈發(fā)電，可降低煤炭消耗。

　　1. The amount of crop straw is large, the coverage is wide, and the fuel source is abundant. 2. Straw has a very low sulfur content. According to research by the International Energy Agency, the average sulfur content of straw is only 3.8% per thousand, while the average sulfur content of coal is about 1%. And the nitrogen oxides produced by low-temperature combustion are relatively small, so the flue gas after dust removal is not desulfurized, and the flue gas can be directly discharged into the atmosphere through the chimney. The operational tests in countries such as Denmark have shown that the flue gas from straw boilers after dust removal can fully meet environmental protection requirements without other purification measures. So straw power generation not only has good economic benefits, but also good ecological and social benefits. 3. The calorific value of straw varies slightly among different crops, but according to measurements, the calorific value of straw is about 15000KJ/Kg, which is equivalent to 50% of standard coal. The calorific value of wheat straw and corn straw is the smallest among crop straw, with a low calorific value of 14.4MJ/kg, equivalent to 0.492kg of standard coal. Using straw for power generation can reduce coal consumption.

　　4、秸稈通常含有3%~5%的灰分，這種灰以鍋爐飛灰和灰渣/爐底灰的形式被收集，含有豐富的營(yíng)養(yǎng)成分如鉀、鎂、磷和鈣，可用作高效農(nóng)業(yè)肥料。

　　4. Straw typically contains 3% to 5% ash, which is collected in the form of boiler fly ash and ash/furnace bottom ash. It is rich in nutrients such as potassium, magnesium, phosphorus, and calcium and can be used as an efficient agricultural fertilizer.

　　?5、作為燃料，煤炭開(kāi)采具有一定的危險(xiǎn)性，特別是礦井開(kāi)采，管理難度大。農(nóng)作物秸稈與其相比，則危險(xiǎn)性小，易管理，且屬于廢棄物利用。

　　As a fuel, coal mining has certain risks, especially in mine mining, which is difficult to manage. Compared with it, crop straw is less dangerous, easier to manage, and belongs to waste utilization.
