Lignite Storage

Lignite-generated electricity is abundant, low-cost, reliable and environmentally compatible.

Lignite is a dark brown to black combustible mineral formed over millions of years by the partial decomposition of plant material subject to increased pressure and temperature in an airless atmosphere. In simple terms, 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 25-35%.

Lignite is brownish-black in color and has a carbon content around 25-35%, a high inherent moisture content sometimes as high as 66%, and an ash content ranging from 6% to 19% compared with 6% to 12% for bituminous coal. LF would like to propose Large Span Steel Space Frame Shed, which can be used to cover lignite. it can be built with a span of up to 150 m and height of up to 40 m. The construction systems use mild steel in case of lignite storage, no welding is required because the connection of the member consists of a very efficient moment-resistant mechanical joint. Lignite storage shed may be built in single-layer or double-layer configurations, depending on the load and span.

Experience suggests large spans are required in lignite storage; a-double-layer is the most cost-effective. Lignite storage sheds are often built over operating stockpiles since construction can proceed without interrupting operations, because the erection process does not require machines to be installed at the internal periphery of the span.
