A Waste Heat Recovery (WHR) installation is a relatively complex system that is made up of multiple interrelated subsystems. The basic package of a steam-based WHR system consists of heat recovery boilers, a steam turbine, an electric generator, a condenser, steam piping, condensate piping, lubrication systems, cooling systems, water-treatment systems and electrical equipment.
Installation of waste heat recovery equipment capable of 20.6 MW of power generation was completed after construction and system demonstration. The system generates approximately 280 MW of power, which accounts for 6% of all the electricity used at the Vizag Steel Plant.

Abstract: Waste heat recovery is the use of thermal energy that would otherwise be transferred to the environment to accomplish a useful function.Examples for internal combustion engines include the use of engine coolant for cabin heat, turbocharging to increase power density, bottoming cycles to produce additional work from exhaust gas, or integrated exhaust manifold to facilitate engine warm-up.
The study aims to investigate the effects of the steam plant components deterioration in a marine Waste Heat Recovery (WHR) system. WHR technology can significantly improve the energy efficiency of merchant ships, because it allows to recover thermal energy from the exhaust gas of the main diesel engines, in order to produce electric energy through a steam turbo-generator.
Improve Plant Efficiency with Waste Heat Recovery . In the process industry today, where environmental sustainability is becoming and increasingly important driver in plant decisions, operators need to focus on any means available to reduce energy consumption.
The heat sources are energy recovery from exhaust heat of large diesel internal combustion (IC) engines, geothermal brines as a byproduct of oil and gas production and waste steam from a typical process industry plant.

Of the various technology options for external heat recovery, the combined gas steam power plant is by far the most effective and commonly used worldwide. For internal heat
WASTE HEAT RECOVERY SYSTEM 1. WASTE HEAT RECOVERY SYSTEM 2. INTRODUCTION The primary source of waste heat of a main engine is the exhaust gas heat dissipation , which accounts for about half of the total waste heat, i.e. about 25% of the total fuel energy. the exhaust gas temperature is relatively low after the turbocharger, and just high enough for producing the necessary steam for the

6 WASTE HEAT RECOVERY IN TURKISH CEMENT INDUSTRY Turkey is the fourth-largest producer of cement in the world and the largest one in Europe. The industry is the second-biggest consumer of industrial energy in Turkey, with a total consumption of 6426 thousand TOE equivalent in 2016, representing about 6 percent of Turkey's total energy use.
It was not until 1999 that the concept took center stage again when two compressor stations in Alberta, one with TransCanada Pipelines at Gold Creek and the other with the Alliance Pipeline system, were enhanced by waste heat-recovery plants. Both of the heat-recovery systems were based on a propane cycle and were designed and built by Ormat.

Waste Heat Recovery (WHR) If not captured and used, waste heat is released to the atmosphere missing an energy efficiency and environmental protection opportunity. Waste Heat Recovery (WHR) is the process of collecting waste heat and converting it to electricty or using it on a desired purpose elsewhere.
Recovering waste heat is one of the easiest and most effective means of reducing operating cost. Exhaust heat from energy consuming processes and exhaust stacks is returned through a metal heat exchanger it as process air, preheated combustion air or plant comfort heat.
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.
Waste heat can be considered as either low grade (<100°C), medium grade (100°C-400°C) or high grade (>400°C). Low grade waste heat can only be recovered effectively when there is a high quantity of waste heat and a ready use for it. There are many examples of successful heat recovery projects for temperatures between 100°C and 200°C.
