煤的特性煤作为燃料,对锅炉、煤粉制备和燃烧系统的设计如运行具有很大影响。燃烧的复杂性起源于煤种特性。根据试验和经验公式可从煤的含灰量、灰的成份及其在煤中的相对比例来确定它的结渣性和沾污性,并以此指标作为蒸汽锅炉设计的依据,按照煤的发热量及可磨度确定所需磨煤机的型式及数量;热失重曲线表示燃料燃烧的相对稳定性及燃烧所需的时间。还可作为确定燃烧方式 Characteristics of coal Coal, as a fuel, has a great influence on the design of boilers, pulverized coal preparation and combustion systems such as operation. The complexity of combustion originates from coal characteristics. According to the experimental and empirical formula, it can be determined from the ash content of ash, the composition of ash and its relative proportions in coal to determine its slagging and stainability. Based on this indicator as the basis for designing a steam boiler, Calorific value and grindability to determine the type and amount of pulverizer required; and the thermogravimetric curve represents the relative stability of combustion and the time required for combustion. But also as a way to determine the combustion
