trying to recover some waste heat coming out from the industry. Most of the heat is wasted around the boiler of the steam power plant, or around the exothermic reactor, or through the flue gases coming out from chimney or stack. Using Kalina cycle we perform heat recovery task quite easily. Kalina cycle uses Ammonia and Water as working fluid.
A Review on Cement Waste Heat Recovery Mehul A Shah M.E. Student (Thermal Engineering) Department of Mechanical Engineering A. D. Patel Institute of Technology, New V.V.

Therefore, increasing de-mand for energy and water requires even more energy efﬁ ciency for the cement making process. Also, the cost of energy is a signiﬁ cant factor in the cost of ce-
Summary: The generation of power from waste heat in cement plants was for a long time the subject of controversial discussion. Today, hardly anyone remains unconvinced by the concept. Depending on the system used, 30–45 kWh/t clinker can be generated, which is up to 30 % of the electrical power requirement of a cement plant. The benefits of this technology are clear.
RD&D to advance waste heat recovery technologies. Technology needs are identified in two broad areas: 1) extending the range of existing technologies to enhance their economic feasibility and recovery efficiency, and 2) exploring new methods for waste heat recovery, especially for unconventional waste heat sources.

Dec 19, 2011· A process to capture CO 2 by integrating the recovery and utilization of waste heat has been designed. Aspen Plus software was used to calculate the amount of waste heat and the efficiency of energy utilization. The data used in this study was based on a dry process cement plant with a 5-stage preheater and a precalciner with a cement output of ...
Heat recovery for power production may not be feasible in plants where the waste heat is used in raw mills to extensively dry the raw material - which offers a more efficient and economic option (US EPA, 2010. p22). It has been reported that there are at least 33 cogeneration units in various cement plants with total capacity about 200 MW in Japan.
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.
Waste heat is a valuable resource. Johnston Boiler Company's line of single and triple pass Waste Heat Recovery (WHR) boilers offer your company a way to save valuable energy, energy typically lost in waste heat.

Principle Heat recovery units. Waste heat found in the exhaust gas of various processes or even from the exhaust stream of a conditioning unit can be used to preheat the incoming gas. This is one of the basic methods for recovery of waste heat. Many steel making plants use this process as an economic method to increase the production of the plant with lower fuel demand.
flow of heat in the plant in most cases. The basic idea behind waste heat recovery is to try to recover maximum amounts of heat in the plant and to reuse it as much as possible, instead of just releasing it into the air or a nearby river.
