Effect of calcium sulphate and calcium carbide on nitrogen use efficiency 31 application even at lower rate supplemented with calcium as CaSO4 or CaC2 showed better performance than that of straight N application in both normal and saline-sodic

From this beginning, calcium carbide and acetylene manufacturing spread around the world. Acetylene, used first for lighting homes, railways, mines, and marine buoys and then for oxyacetylene welding, became one of the foundations of the synthetic organic chemicals industry.

Carbide slag, also known as calcium carbide residue (CCR), is a by-product of the hydrolysis of calcium carbide. It is commonly generated from the industrial production of ethylene, polyvinyl chloride (PVC) and other products as a solid waste. Currently, it has no value for recovery and is commonly landfilled. At some Chinese plants, this slag is used as an alternative raw material for cement ...

The carbide lamp in action! These devices offer efficient, carry-along lighting for all kinds of outdoor activities. Mixing water with calcium carbide crystals inside the burner produces acetylene ...

The development and use of this engineered carbide desulphurizer has made possible great environmental and efficiency improvements in the field of calcium carbide desulphurizing. Consequently, the lifespan of calcium carbide in ductile iron desulphurization has been increased as have the benefits of its use in the foundry industry.

Calcium carbide market size may further grow due to its usage in integrated steel mill desulfurization. The product acts ladle deoxidizer and slag conditioner to remove sulfur and iron oxide. It is also added in an electric arc furnace owing to its property to enhance energy efficiency.

Desulphurization of pig iron using calcium carbide based reagents C. BRODRICK SA Calcium Carbide Use of calcium carbide based reagents is a long established practice for the desulphurization of pig iron/hot metal resulting in the removal of the sulphur from the molten metal as calcium sulphide into the slag floating on the molten metal surface.

and calcium carbide production process providing electrical energy for own-use and thermal (heat) energy for use in the aggregates drying kiln – and is in no way a "project tag on". Increased furnace production efficiency, for example, produces increased efficiency on .

A calcium carbide based power system for stationary and mobile power plants. The carbide is reacted with water to create heat and acetylene, with the acetylene then being burned to heat a boiler for providing steam to a steam turbine. The exhaust of the turbine is condensed and pumped back into the boiler, first being pre-heated by a heat exchanger in the carbide-water reactor to pre-heat the ...

The exhaust of the steam expander is condensed and pumped back into the boiler, first being pre-heated by a heat exchanger using the heat in burner exhaust gas ...

It's much easier and more cost-effective to design a plant for energy efficiency up-front than retrofit an existing one. We conduct energy-efficiency reviews throughout all stages of design, from concept studies to detailed engineering design. This ensures energy use is .

Electric arc furnaces are also used for production of calcium carbide, ferroalloys and other non-ferrous alloys, and for production of phosphorus. Furnaces for these services are physically different from steel-making furnaces and may operate on a continuous, rather than batch, basis.

Two hydraulic pumps help to open and close the supply of calcium carbide, which is fed into the generator by screw feed conveyors. The screw feed mechanism and the agitators are operated by flameproof motors and fittings. The entire operation is perfectly synchronized to achieve maximum efficiency and simplicity in operation.
