11.10.2020· Brown coal can be more difficult to use than other types of coal. For instance, it can be susceptible to spontaneous combustion, making transporting and storing it problematic. Due to its transportation limitations, brown coal is often burned in a utility plant that has been set up near a lignite

Lignite has the lowest ranking in the coal classification system, and it is mostly used as fuel in the power sector. Lignite's colour ranges from brown to black (see Figure 2.7) and its heating value is less than 19.306 KJ/Kg. Due to the fact that lignite deposits are geologically young they may contain plant debris.

The spontaneous ignition that occurs with upgraded lignite products is a concern for its storage, handling, and transportation. The Basket testing method and Oxidation Kinetics testing method were used to identify the propensity for upgraded lignite products to spontaneously ignite. The evaluation index for the Basket testing method was spontaneous ignition temperatures and duration. The

Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat.It is considered the lowest rank of coal due to its relatively low heat content.It has a carbon content around 60–70 percent. It is mined all around the world, is used almost exclusively as a fuel for steam-electric power generation, and is the coal which is most

Spontaneous combustion has become a critical limiting factor for the safe and efficient utilization of low rank coals. In this work, the alkali-oxygen oxidation (AOO) of Chinese Shengli lignite was conducted to inhibit the spontaneous combustion tendency, and the influences of AOO on the structures and combustion properties were investigated.

Uses of lignite. The high moisture content and susceptibility to spontaneous combustion as well as relatively low energy density of lignite coal can cause problems in transportation and storage. Hence, the coal is generally used close to the mines (known as mine mouth operations).
