Ⅲ 一篇描寫農田秸稈燃燒現象的英語作文，介紹看到的景象，反映出的危害，採取的措施
通過對稻稈來原料進行常規源特性分析和EDX元素含量分析,發現鉀在稻稈無機元素中佔有重要地位。參考原料化學分餾法和土壤中鉀的分類與測試方法,給出了對生物質原料及其燃燒產物中鉀的定性與定量簡易方法。通過程序控溫型固定床對稻稈先進行緩慢氧化,然後以100℃為間隔從400~900℃進行成灰,並分別測試其成灰率、有效鉀和全鉀的份額。結合稻稈原料及其灰中鉀的份額分析,進行了稻稈灰中有效鉀轉化與釋放的計算,發現有效鉀在700~800℃之間有快速的釋放和形態轉變。稻稈灰的XRD分析結果表明秸稈灰中鉀主要以KCl、K_2SO_4形式存在,得到了鉀以鹽的形式進行轉化與釋放的機理。該文中燃燒溫度對鉀轉化與釋放的影響規律對設計秸稈電廠時的爐型選擇和燃燒參數確定有一定參考價值。
