Key words:Cement Plant, Rotary kiln system, Energy Balance, Heat Balance, Heat Recovery Abstract Waste Heat Recovery (WHR) is the process of recovering heat dischargedas a byproduct of one process to provide heat needed by a second process. So it is the capture and the use of
Waste Heat Recovery Power Plants, contribute significantly, to the electrical energy saving (to the tune of 25%). The reduction in CO 2 emission, makes it environmental friendly. Installation of the waste heat recovery plant has to be tackled as a system approach, rather than considering cement plant and WHRPP operations, independently.

Three exergy efficiencies of a cement kiln plant are defined as follows: 1 Exergy efficiency, η ex = clinker formation exergy/ exergy input. It corresponds to the net thermal efficiency, η g, defined as the fraction of fuel heat that is consumed as latent heats of various clinker forming reactions (1) .
i KEYWORDS Cement, energy, emission, life cycle inventory ABSTRACT This report is an update of Life Cycle Inventory of Portland Cement Manufacture published in 2002. The purpose of this update is to incorporate the most recent energy use data from the
waste heat from cement plants into electricity. The ABB ORC power plant The core of the power plant is a onestage turbine. Due to the waste heat''s lowtemperature, water vapour can not be used efficiently, both in terms of energy and of costs. Therefore, organic fluids are
cement plant. Reduction of the production cost and consumption cost is very much important because of that waste heat recovery is implemented in the cement industry. The waste heat recovery reduces the Green house gas emissions and enhances the overall system performance.

There is a more potential in a cement factory for electric power generation using waste heat recovery compared to the other industries. A case study has been done at a cement factory having two units, 1600 TPD and 5500 TPD, identified three waste heat rejections at 176 °C, 330 °C and 420 °C and designed a suitable power plant configuration.
