During the design of a power plant, the steam flow rates extracted from the turbine must be determined. This is usually made by making the heat balance (heat in = heat out) and the mass balance (flow rate in = flow rate out) for the regenerative circuit. The steam flow rates result from the balance equations, written for each heat exchanger apart.
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.
heat balance calculation in cement plant . AS a leading global manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any sizereduction requirements, including quarry, aggregate, grinding production and complete stone crushing plant.
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.
effective and efficient energy management scheme. Actual data, which are taken from a cement plant located in Gaziantep, Turkey, are used in numerical calculations to obtain energy balance for the system. It is calculated that MWof energy is lost from the surface of the kiln which accounts for the % of the total energy input to the unit.
principle based model of grate cooler for cement plant. In this work, the temperature variation and assumptions of the model will be discussed. The model is developed for steady state condition. Variations of gas, solid temperature, wall temperature and heat losses through the wall are simulated with respect to grate cooler length.
