Can lignite be burned using a chain burner? How is it performing in practice?
Thread Content
I now come into contact with lignite fuel at work; I wonder what its properties are? Is it suitable for combustion using a chain grate? What issues should be considered when using a chain grate? How is it performing in practice?
Compared to other types of coal, lignite has a lower calorific value, higher moisture content, higher oxygen content, higher volatile matter, and more ash; it is generally considered to be a low-quality fuel. In particular, the high ash and moisture content result in a large amount of heat being lost during combustion. Power station boilers that burn lignite primarily use a suspended combustion method, namely pulverized coal combustion boilers (pulverizer boilers). Cyclone combustion boilers (cyclones) are used in small quantities. In recent years, with the development of fluidized bed combustion technology, fluidized bed combustion boilers have also begun to be used for burning lignite to generate electricity. When used in small-capacity industrial furnaces and industrial boilers, lignite is primarily burned in a layered manner, such as in chain furnaces, reciprocating furnaces, and fluidized bed burners. .
