Cottonseed oil has been used as a fuel source either as a blend with diesel in varying proportions or undiluted (100%) in numerous studies evaluating its potential use in internal combustion engines. However, limited research is available on the use of cottonseed oil as a fuel source in a multi-fueled burner similar to those used by cottonseed oil mills and cotton gins in their drying operations. The purpose of this study was to evaluate emissions from five fuel oil treatments while firing a multi-fueled burner in a setup similar to those used for drying operations of both cottonseed oil mills and cotton gins. For each treatment, gaseous emissions were measured while firing the burner at three fuel flow rates. The five fuel oil treatments evaluated were: (1) No. 2 diesel at 28.3 degrees C, (2) prime bleachable summer yellow (PBSY) cottonseed oil at 28.3 degrees C (PBSY-28), (3) crude cottonseed oil at 28.3 degrees C (Crude-28), (4) PBSY at 60 degrees C (PBSY-60), and (5) crude at 60 degrees C (Crude-60). Results indicate that PBSY treatments had the lowest overall emissions of all treatments. The other treatments varied in emission rates based on treatment and fuel flow rate. Preheating the oil to 60 degrees C resulted in higher NO(x) emissions but displayed varying results in regards to CO. The CO emissions for the crude treatments were relatively unaffected by the 60 degrees C preheat temperature whereas the preheated PBSY treatments demonstrated lower CO emissions. Overall, both cottonseed oils performed well in the multi-fueled burner and displayed a promising potential as an alternative fuel source for cottonseed oil mills and cotton gins in their drying operations.
在众多评估棉籽油在内燃机中潜在用途的研究中，棉籽油已被用作燃料来源，要么与柴油按不同比例混合，要么未经稀释（100%）使用。然而，关于在类似于棉籽油厂和轧棉厂干燥作业中使用的多燃料燃烧器中，将棉籽油用作燃料来源的研究有限。本研究的目的是在一个类似于棉籽油厂和轧棉厂干燥作业所用的装置中，对多燃料燃烧器燃烧五种燃料油处理方式时的排放情况进行评估。对于每种处理方式，在燃烧器以三种燃料流速运行时测量气体排放。所评估的五种燃料油处理方式分别为：（1）28.3摄氏度的2号柴油，（2）28.3摄氏度的优质可漂白夏季黄（PBSY）棉籽油（PBSY - 28），（3）28.3摄氏度的粗棉籽油（Crude - 28），（4）60摄氏度的PBSY（PBSY - 60），以及（5）60摄氏度的粗棉籽油（Crude - 60）。结果表明，PBSY处理方式在所有处理方式中总体排放最低。其他处理方式的排放率因处理方式和燃料流速而异。将油预热至60摄氏度会导致更高的氮氧化物（NO(x)）排放，但在一氧化碳（CO）方面表现出不同的结果。粗棉籽油处理方式的CO排放相对不受60摄氏度预热温度的影响，而预热后的PBSY处理方式则显示出较低的CO排放。总体而言，两种棉籽油在多燃料燃烧器中表现良好，作为棉籽油厂和轧棉厂干燥作业的替代燃料来源显示出有前景的潜力。
