How much space is required for vertical lime kilns to burn lime
The site requirements for a vertical lime kiln require a comprehensive consideration of factors such as process layout, environmental protection facilities, and production capacity planning. It is usually divided into three parts: core production area, auxiliary functional area, and safety buffer zone.
Core production area
The kiln base covers an area of about 100-200 square meters (estimated based on a daily production capacity of 100-300 tons), and equipment maintenance channels need to be reserved. The raw material storage yard needs to have a limestone storage capacity of 3-7 days. Calculated based on an area of 2-3 square meters per ton, it requires 2000-5000 square meters. The finished product warehouse and loading and unloading area need to accommodate temporary storage of quicklime, and it is recommended to plan for 500-800 square meters. The fuel storage area (coal or gas equipment) needs to be independently set up, covering an area of approximately 300-600 square meters.
Auxiliary functional area
Environmental protection facilities (dust collectors, desulfurization towers) require supporting equipment rooms, covering an area of approximately 400-800 square meters. The distribution room, control room, and office area require 200-400 square meters. The circulating water tank and water pump room (if using water mist cooling) require 300-500 square meters. The road system needs to meet the passage of heavy-duty vehicles, with a main channel width of not less than 8 meters and a circular lane occupying approximately 1000-1500 square meters.
Safety buffer belt
According to the Design Code for Kilns in the Building Materials Industry, the distance between the kiln body and the surrounding wall should be ≥ 15 meters, and the distance between the storage yard and the office area should be ≥ 30 meters. The recommended width for the green isolation belt is 5-10 meters, which also has the function of noise reduction and dust reduction.
Comprehensive calculation
The daily production of 100 ton lime kilns covers a total area of approximately 12000 to 15000 square meters, while 300 ton kilns require 20000 to 25000 square meters. In actual planning, consideration should be given to terrain slope (recommended ≤ 5%), dominant wind direction (environmental protection zone arranged on the downwind side), and geological bearing capacity (kiln foundation needs to reach 20 tons/square meter or more). By optimizing the three-dimensional storage design and automated conveying system, the land utilization rate can be increased by about 15% -20%. Suggest reserving 10% -15% expansion space to accommodate future capacity upgrade needs.
