Electric energy is an important energy in calcium carbide production. Large and medium-sized calcium carbide furnaces can meet the needs of living lighting in small and medium-sized cities. Therefore, energy conservation in calcium carbide production is an important thing. Energy conservation can not only be used to increase production and support construction, but also for units. Because the unit cost of calcium carbide products accounts for more than half of the cost, reducing the unit electric energy is also the key to reducing the product cost.
The former Ministry of chemical industry attached great importance to the saving of calcium carbide electric energy. The experience exchange meetings on high production and low consumption of enterprises in calcium carbide industry have been held for many times to formulate corresponding energy-saving measures and means. In recent years, due to the deepening of energy conservation and emission reduction, calcium carbide production has developed from extensive to fine, backward internal-combustion calcium carbide furnaces have been gradually eliminated, and a large number of closed calcium carbide furnaces have sprung up and developed, mainly to recover their waste gas. Calcium carbide industry association has made arduous efforts for this.
