Lignite storage – Coal Storage shed
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
- Lignite is abundant and accessible.
- Lignite-generated electricity is reliable.
- Lignite-generated electricity is environmentally compatible.
- Lignite-generated electricity is low-cost.
- Lignite is used in an environmentally responsible manner by power plants.
Lignite has a high content of volatile matter, which makes it easier to convert into gas and liquid petroleum products than higher-ranking coals. Unfortunately, its high moisture content and susceptibility to spontaneous combustion can cause problems in transportation and storage.
It is now known that efficient processes that remove latent moisture locked within the structure of brown coal will relegate the risk of spontaneous combustion to the same level as black coal, will transform the calorific value of brown coal to a black coal equivalent fuel, and significantly reduce
the emissions profile of ‘ densified ‘ brown coal to a level similar to or better than most black coals.
Because of its low energy density and typically high moisture content, brown coal is inefficient to transport and is not traded extensively on the world market compared with higher coal grades. It is often burned in power stations near the mines, Primarily because of latent high moisture content and low energy density of brown coal, carbon dioxide emissions from traditional brown-coal-fired plants are generally much higher per megawatt generated than for comparable black-coal plants, The operation of traditional brown-coal plants, particularly in combination with strip mining, can be politically contentious due to environmental concerns.
We would like to propose Large Span Steel Shed, which can be used to cover lignite; it can built with a span of up to 150 m and height of up to 40 m.The construction systems uses 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- 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 our erection process does not require machines to be installed internal periphery of the span.
Roofing of the structure:
Galvalume is typically use for roofing purpose, Galvalume is lustrous spangled appearance is attractive enough to be used without painting. The GALVALUME sheet is a unique product which is suitable for heating and ventilation applications. It has better resistance towards oxidation and can withstand temperatures up to 315°C without discoloration. This feature of Galvalume enables us to use on limestone shed for roofing purpose.
- Smooth Surface and uniform spangled appearance
- Excellent quoting with anti-fingerprint to ensure better appearance and longer life
- Surface treatment as per ROHS (Restriction On Hazardous Substance) norms
- Wider thickness range with tighter tolerances to ensure precision in end-applications
Advantage of Lignite storage shed:
- For achieving effective prevention and control of potential fugitive emission
- Lesser Operation and Maintenance cost
- Comply with current environmental guidelines by CPCB (Central Pollution control board)
- Protection from weird environmental condition
Our Structure is fully Complying with new environmental regulations for air quality, Prevention and control of fugitive emission. Instead of investing in temporary solution, it is recommended to adopt permanent solution. Our solutions presented here not only allow affordable compliance, but also enhance the reputation of your plant. In addition, one time investment is much more economical than the periodic investments
