Coal Storage Shed, Dome, Vault & Stockpile
Bulk Storage Dome


Coal sheds are large in size and stores tons of coals. As for any thermal power plant, steel plant, cement plant etc where the boilers require the continuous supply of coal, the coal handling plants are a necessity and play a critical role. For continuous supply the conveyors and stackers reclaimers are installed for effective feeding. To protect equipments from extreme weather conditions and also to protect the coal exposed to these weather conditions, the need to construct the coal shed is important. We are the leading coal storage sheds, dome, vault, building and stockpile manufacturer, installation and all solutions from last 20 years in India and worldwide with assurance of quality and durability

Bulk Storage

Moreover, the dusty conditions created by the coal, it is very important to have the covered coal shed. Due to the fugitive dust emission, the dust particles are carried by the wind and causes pollution. This would pollute the plant area and could damage other utilities of the plant. The loss of coal is also due to spontaneous combustion. Large quantity of water is consumed daily for dousing the fire due to spontaneous combustion. This should be avoided, as excessive moisture in the coal would aid heating of the coal. The erosion due to wind and rain is reduced with the covered storage. By providing the covered storage, the operating expenses of the plant are also lowered. Space efficiency, structural strength and durability, adaptability, cost savings, quick construction, environmental advantages, increased safety, better inventory control, and aesthetic appeal are a few advantages of bulk storage dome.

The covered storage can be longitudinal covered shed or Dome type covered shed.

Longitudinal Covered Shed

In this case, coal storage will be formed by the conventional rail mounted stacker cum reclaimer. The entire coal and the Stacker cum reclaimer machines will be covered within the shed. The length and span of the shed could be adopted depending on the quantity of storage required. In case of future expansion the length of the shed can be increased and same stacker reclaimer can be used for higher volumes.

Dome type structural storage shed

In this type of structure, the shape of the shed will be in the semi hemispherical form. There will be a concrete wall up to a certain height from the ground level and the structure will be erected above this wall. The dome structure of various sizes could be adopted depending on the quantity of storage required. A circular stacker and scraper type reclaimer could be used for reclaiming the coal. With this type of shed, coal will protected from wind and rain and hence the problems associated with these will be avoided. This kind of storage shed can accommodate higher quantity of coal in a smaller area as the height of storage could be increased.

Lignite Storage & Dome

Lignite generated electricity is abundant, low-cost, reliable and environmentally compatible. It 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, It is 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. We would like to propose a Large Span Steel Shed, which can be used to cover a lignite dome; it can be built with a span of up to 150m and height of up to 40m. The construction system 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. Bulk storage is a large span, designed to hold tons of coal so the boilers may be continuously supplied with fuel. Modular space frames are used in the design of bulk storage to save costs when compared to more traditional structure types.

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 a lignite dome, 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 on the internal periphery of the span.

The integrated terminal buildings are designed with number of structural innovations. The key feature of airport structure is their long span roof covering with massive column spacing. The mega columns and large cantilevers make the structure unique. By using modular space frame structure supported by cantilevered columns makes the roof aesthetically good with doubly curved.

Pre-Engineered Buildings

It offers a futuristic solution for creating durable and efficient structures in cost effective manner. Apart from great flexibility of designing and minimal construction time offered by PEB’s, they are also preferred for their robustness and durability. Moreover, it is possible to add a wide range of structural and non structural components, which enhances their aesthetic appeal and also improve their usability.

Space Frames

Space frame is a three dimensional structure. The 3D behavior ensures optimum utilization of material. The quality of roofing is exceptional good as the deflections are almost negligible. Despite their light weight, these structures are designed to carry much heavier load and have a huge spanning capacity. Erection time is minimal as the material is pre fabricated from the factory.

Multi-Storey Buildings

Steel frames construction is a very popular structural form for multi storey buildings as it provides great flexibility. The structure has adequate strength and stiffness to resist the applied loads due to gravity and wind. The function of the structure in resisting vertical loads due to gravity and horizontal loads due to wind is generally considers separately.

Bulk Storage Sheds

Bulk storage sheds are large span structure to accommodate tons of coals for continuous supply to the boilers.The structures are designed with modular space frame to make it cost effective compared to other conventional structures. Catwalks, ducts and other services can be accommodated within the top and bottom chord.

Membrane Structures

Textile supported by steel combines the high flexibility of use of this one, from reticular arches to infinite space geometries, with a singular covering applied only with optimum conditions in order to avoid abrasion and corrosion due to contact with main bearing structure. The all season use is guaranteed by a singular system of side opening in order to obtain maximum ventilation in hot season.

Self Supporting Roofs

Self supporting roofing system makes it possible to erect a warehouse in one span without trusses, purlins and rafters. The systems are mechanically sealed which ensures better weather proofing and a hygienic and clean environment. The absence of holes, nuts, bolts, overlaps or sealants, these structures require minimal to zero maintenance making them highly cost efficient.
