Fuel-a substance composed of chemical elements, which in rapid chemical union with oxygen produced combustion. Combustion-is that rapid chemical union with oxygen of an element, whose exothermic heat of reaction is sufficiently great and whose rate of reaction is sufficiently fast, whereby useful quantities of heat are liberated at elevated temperatures.
Grinding occurs at the beginning and the end of the cement making process. Approximately 1.5 tonnes of raw materials are required to produce 1 tonne of finished cement. The electrical energy consumed in the cement making process is in order of 110 kWh/tonne and about 30% of which is used for the raw materials preparation and about …
MIT's Department of Mechanical Engineering (MechE) offers a world-class education that combines thorough analysis with hands-on discovery.

Improving the Internal Combustion Engine, Part 1. The internal combustion engine may be a marvel of engineering, but that doesn't mean it's necessarily a modern one. In fact, the basic design pioneered by Jean Lenoir in the 1850s isn't too far off from the engine that is likely powering your car today. The idea of fuel ignited within a ...

Steam, CO2 and N2 Inerting Systems. Technically speaking it is generally accepted that achieving an "inert" environment inside a coal mill, the O2 level should fall below 14% O2. Technically speaking, only Steam, CO2 and N2 (Rare) systems are true inerting systems. Steam is the most common inerting media.
