Thermochemical heat storage based on CaO/CaCO3 cycles suffers from an obvious decline in heat storage capacity attributed to the sintering of particles. Reactive molecular dynamic simulations are carried out to investigate the sintering mechanism of CaO and CaCO3 particles. Lower mass center distance ...
The apparatus of the invention makes use of a heat exchanger which functions as a radiant cooler and also as a mixer for the gases and solids, the heat exchanger being connected directly to the gasification reactor at the exhaust gas side thereof. The heat exchanger is followed by at least ...
The meaning of CALCIUM is a metallic chemical element of the alkaline-earth group that occurs naturally only in combination and is essential to cellular functions in all known organisms. How to use calcium in a sentence.
DescriptionCalcium oxide (CaO, CAS Reg. No. 1305-78-8) is also known as lime, quick lime, burnt lime, or calx. Lime does not occur naturally since it reacts so readily with water (to form hydrated lime) and carbon dioxide (to form limestone). It is produced from calcium carbonate, ...
