The heat balance application always contains IN1, OUT1 and BAL sheets. A pair of IN and OUT sheets is called a Balance area, which may be considered equivalent to a control volume. A total number of 127 balance areas may be inserted, to create a multiple balance area workbook.
However there are few detailed thermodynamic analyses of operating cement plants that evaluate the option of waste heat recovery. This paper builds up an energy balance for an operating plant and estimates the power that can be generated from the waste heat streams.
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.

competition in cement industry, lowering the product cost has become the need of the hour for survival. An effective measure to reduce the production cost is by optimisation of operational practices. Process optimisation is an effective tool for improving the effectiveness of the system and hence, cost reduction in cement industries.
The heat balance calculation provides a snap shot of the specific heat consumption of the kiln system with the kiln in stable operating conditions. The purpose of heat balance calculation is to:- Establish the specific heat consumption of the stably operating kiln. Yield information about where the heat losses occur in the system.
