Application of ESP for gas cleaning in cement industry ...
ESP–FF combination is also useful for large size plants, considering large gas volumes emitted by such plants and the requirement of large size ESP for gas cleaning. As an example, a 4000 tonnes per day cement plant will emit approximately 0.5×10 6 m 3 /h of gas from its preheater kiln at 250°C. This makes ESP size considerably large ...

Furnace Types. Table 3-2 lists the types of furnaces used for municipal solid-waste, hazardous-waste, and medical-waste incineration. Municipal solid-waste furnace designs have evolved over the years from simple batch-fed, stationary refractory hearth designs to continuous feed, reciprocating (or other moving, air-cooled) grate designs with waterwall furnaces for energy recovery.

Gas Turbine - an overview | ScienceDirect Topics
Then, rather than deploying a steam plant, it might be more appropriate to use an organic Rankine cycle (ORC) power plant. In such cases, the vapor-generating system would be simpler (only a heat exchanger would be needed) and the condenser could be air-cooled. ORC units are smaller in output than steam units and typically generate about 5 MW ...

Energetic and exergetic analysis of waste heat recovery ...
For the water-steam cycle it is clear that the main exergy loss is from the exhaust gas (Table 4a) because of its high exit temperature (270 °C), which is a restriction imposed by the production process of the cement plant. The next major exergy destruction is located in the two heat exchangers that operate as evaporators.

Parametric Studies of Cement Production Processes
The cement industry is one of the most intensive energy consumers in the industrial sectors. The energy consumption represents 40% to 60% of production cost. Additionally, the cement industry contributes around 5% to 8% of all man-made CO 2 emissions. Physiochemical and thermochemical reactions involved in cement kilns are still not well understood because of their complexity.
