The closure of the coal storage yard is to cover the coal yard with a large-span steel space frame structure and color steel sheets to build a stable, safe and environmentally friendly building.
It is designed as a strip-shaped closed coal yard or a dome closed coal yard, and a fully enclosed environmentally-friendly coal storage yard is adopted. It can complete the optimization design of construction drawing, material manufacturing, processing and supply, site installation and construction, etc.
To design the ventilation of the fully enclosed coal bunker, it can be use the fully enclosed coal bunker ventilation design and evaluation system, which can design and evaluate the ventilation of the coal bunker according to the working conditions of the coal bunker, and give a perfect ventilation plan. Air curtain type ventilation belts can also be used to achieve zero dust spillage while ensuring good ventilation.
To properly ventilate a fully enclosed coal silo, the wind environment after the coal yard is fully enclosed should generally be determined according to the prevailing wind direction, wind speed and the layout of the coal yard.
It is necessary to establish a ventilation system for the upper, middle, lower and both ends of the coal bunker, and calculate the size of each ventilation area and the structure of the ventilation components to prevent the leakage of coal dust while ventilation. Good ventilation can greatly improve the working environment in the fully enclosed coal bunker and reduce the risk of dust explosion and occupational health and safety of operators by more than 70%.
In order to ensure the safe operation of the power plant, the power plant has a coal storage yard. It can store a certain amount of coal to prevent the interruption of fuel transportation and affect power production. At the same time, it can adjust the imbalance of coal quantity and boiler fuel quantity. Sometimes the coal yard can also be used for natural drying of blended coal and high-moisture coal.
The overall layout of different power plants is different, and the types of closed coal storage yards are also different, such as round, strip and fan shaped. Most power plants use strip coal storage yards, and a few power plants use circular or fan shapes.
