Heat Energy Recovery

The prime objective of this paper is to present the details of a thermoelectric waste heat energy recovery system for automobiles, more specifically, the surface heat available in the silencer. The key is to directly convert the surface heat energy from automotive waste heat to electrical energy using a thermoelectric generator, which is then regulated by a DC–DC Cuk converter to charge a battery using maximum power point tracking. Hence, the electrical power stored in the battery can be maximized. Also the other face of the TEG will remain cold. Hence the skin burn out accidents can be avoided. The experimental results demonstrate that the proposed system can work well under different working conditions, and is promising for automotive industry.

Industrial plants are excellent sources of waste heat and provide many opportunities for energy harvesting using thermo-electric principles. A thermoelectric generator (TEG) is utilized in this study for harvesting expended heat from various sources. The main challenge associated with this type of technology lies in the creation of a sufficient thermal gradient between the hot side and the cold side of the TEG device. This is necessary for the module to generate an appreciable quantity of electrical energy. The performance of the TEG generator is tested using different configurations, different heat sources and different cooling methods. Heat sources included electrically driven devices, gas, biomass and gel fuel. Expended heat from different sites within an industrial environment was also chosen for operating the TEG device. The power produced by the generator is sufficient to operate low power LED lights, a DC radio receiver and a cellular phone charger.

The growing concern on energy conservation and reduction of carbon footprint has led to a lot of inventions and innovations in terms of energy-efficient technologies in all the energy consuming applications. The automobile sector is a crucial zone where these technologies have a major role to play due to the sheer abundance of the number of automobiles.Many small refinements, alterations and innovations are happening in this field which has led to furthermore energy economic automobiles than before.But even in an advanced internal combustion engine, about two-thirds of fuel consumed by an automobile is discharged into the surroundings as waste heat. The effect of this is the increase in the surrounding air temperature which in turn contributes significantly to global warming. This paper proposes amethod to reduce the emission of heat from automobiles by designing and implementinga waste heat recovery system for internal combustion (IC) engines. The key aim is to reduce the amount of heat released into the environment and to convert it into useful energy. A thermoelectric generator (TEG) assembly is used to directly convert the wasted heat energy from the automobile into electrical energy. This electrical energy is conditioned using a Cukconverter and maximum power point tracking (MPPT) algorithm is embedded in the converter for impedance matching and maximum power transfer from TEG to the converter. The conditioned output is used to charge the battery of the vehicle. This methodologyalso increases the energy efficiency of the vehicle as a higher capacity battery can be employed.The proposed system can work well under varying temperature conditions to give a constant output. It can be implemented in any mechanical/ electrical systems were there is wastage of heat energy like gas pipelines, wearable electronics, space probes, cookstoves, boilers, thermal vision, etc. One of the thrust areas where this technology can be effectively utilized in today’s world is in electric vehicles where the energy efficiency is the most important factor.

Geothermal power plants are the plants that provide the conversion of thermal energy in geothermal fluid to electrical energy as a result of the extraction of underground hot water resources to the earth by drilling. The total installed power of geothermal power plants in the field of geothermal resources in Turkey has reached 1,336 MW. The geothermal fluid, which is used for electric power generation in geothermal power plants, is re-injected into the underground wells after electrical energy production. For efficient generation of electrical energy in geothermal power plants, it is aimed to reuse the waste heat energy within the geothermal fluid before it is sent to the re-injection well. To achieve this aim, thermoelectric generator modules which convert waste heat energy to electrical energy can be used. In this study, a thermoelectric generator-based geothermal power plant simulator that converts geothermal fluid waste heat into electrical energy is installed and commissioned in the laboratory conditions.

The present scenario is like that the need of the electrical energy is growing rapidly whereas the resource availability is lagging behind the load demand due to its extinction which leads to hinder our overall generation. It has been observed that the sustainable resources have great future potential to take lead to generate power and supply demand. In the present scenario there exists a few energy resources equivalent to fuel resource. So, there must be a technology to trap the waste and unutilized heat available in the atmosphere and utilize it into the form useful electrical energy. In the current situation, waste heat in the form of thermal energy is recovered and converted into conventional electrical energy. Today, 70% of produced energy in automobiles is wasted in form of heat by exhaust gases. The main outcome of this paper is to manage the waste heat is being generated in the vehicles efficiently, by introducing the concept of “Thermo Electric Generator” (TEG) which convert the waste heat produced inside the vehicles and Re-Generate in the form electric current and give it back to the “storage unit” due to “Seebeck effect” concept.
