Coal Storage Solutions in Thermal Power Plants

Establishment of the Coal Storage Unit

For electricity generation, many thermal power plants used to store coal at a very large scale or in bulk quantity. Coal (a non-renewable & highly flammable black rock) is a prime and the cheapest producer of heat & electric energy and coal storage is emerged as valuable asset for thermal power producing plants, since combustible quality of coal can be used for electricity generation at an economic cost. Bunkering, Unloading, Stacking and Reclaiming of Coal are the four processes followed in accomplishing coal storage and handling in coal storage area or yard. Bunkering and Unloading of coal is done using transportation as medium only when the source of generated coal is far away from storage place. The two types of coal storage unit are:
  • Open House Unit
  • Covered Shed Unit

Coal Storage & In-plant Safe Handling

Handling the material including the processes – (bunkering and unloading) known as Out-plant coal handling. For rest of the coal handling procedures, a grand machine pronounced as Stacker or Reclaimer is used for facilitating stacking and reclaiming of bulk storage of coal. The prime objective of coal stacking is to produce efficient industrial outcome from coal storage by avoiding problems like oxidation, spontaneous combustion, self-heating, increase in moisture and many more. For environmental friendly coal storage and production of an optimized outcome power, today almost all out-performing thermal power plants use to store coal stockpiles under a strong, durable, eco-friendly and solution-rich coal storage shed.

Hindustan Alcox Limited Specializes In

The proficient and well-versed organisation emerged as India’s apex coal storage shed manufacturer, Hindustan Alcox Limited holds a tremendous experience of 20 years in producing Coal domes & storage sheds. The competitive and best feasible storage solutions provided by the company for storage of coal are:-
  1. Coal Storage Barrel Vault Structural Shed
    In barrel vault shed structure, the conventional stacker cum reclaimer is used for coal storage handling and reclaiming purpose. The length and span of the shed are adjustable depending on the storage needed for power production.
  2. Coal Storage Dome Structural Shed
    In dome shed structure, the shape of the shed is hemispherical. This kind of storage shed can accommodate higher quantity of coal in a smaller area as the height of storage can be increased.

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.
