A 90 MW CALCIUM CARBIDE FURNACE ... This paper describes the scale-up for a furnace design rated at 90 MW active (real) power for calcium carbide ... about 10 m diameter and a water-cooled roof (or cover). Three Soderberg electrodes supplied power to the furnace, with
9 · Electric furnace. The lime-coke mixture flows down the furnace until reaching the high-temperature reaction zone, where molten CaO reacts with coke and generates molten calcium carbide. The reaction zone is a packed bed of coke, where empty space is filled with molten calcium carbide and gaseous byproduct carbon monoxide.
The scaled-up calcium carbide furnace is a rectangular six-in-line electrode design with an overall size of 28.7 m x 8.1 m x 7.1 m. The furnace is equipped with a water-cooled roof (cover) that includes an off-gas port at each end.
Lime vertical kiln, just like its name, the shape is erect.It is used for calcination limestone. Due to has low energy consumption, less cover area, less investment, wide applicability fuel, and more advantages, it was widely used in metallurgy, construction materials, calcium carbide, Nanometer calcium carbonate, aerated concrete, sugaring, etc.
A plant experimenting with the utilization of calcium carbide furnace tail gas, built by the Chemical Industry Southwest Research & Design Institute (SWRDICI), at the Ningxia Yinglite Chemical Co, ran the project continuously for 1,000 hours, passed a 72-hour trial and was certified, on Oct 31.
carbide granules or dust. Calcium carbide dust in contact with the skin can react with moisture, creating heat and caustic carbide lime that could cause severe burns. 4.3 Calcium carbide production Calcium carbide is produced by a reaction between coke and burnt lime in an electric furnace at a temperature of 2000°C.
