Abstract

The main purpose of this research was to determine the chemical composition of deposits in gas engines fuelled by coal mine methane (CMM), as well as its dependence on the place of collection. This composition was compared with that for deposits formed in biogas-powered engines. It was also found that the chemical composition of deposits varies depending on the place of their formation in the engine and on the gaseous fuel used. The dominant mineral deposits found in gas engines fuelled by CMM contained Ca, Zn, P, and S, which originate from oil additives. The Al, Cr, Cu, Ti, and Fe elements present in the tested samples are related to the wear of the engine under normal operation. The remaining trace elements can originate as impurities from the air.

摘要

本研究的主要目的是确定以煤矿瓦斯（CMM）为燃料的燃气发动机中沉积物的化学成分，以及其与采集地点的相关性。将该成分与沼气驱动发动机中形成的沉积物的成分进行了比较。还发现，沉积物的化学成分因其在发动机中的形成位置以及所使用的气体燃料而异。在以CMM为燃料的燃气发动机中发现的主要矿物沉积物含有钙、锌、磷和硫，这些元素源自机油添加剂。测试样品中存在的铝、铬、铜、钛和铁元素与发动机在正常运行下的磨损有关。其余微量元素可能源自空气中的杂质。
