Heat Energy Recovery

Drying processes are one of the main consumers of heat energy in production. Any decreases in heat consumption during the drying process will considerably decrease production costs. This study analyzes the high consumption of heat in the drying of baker`s yeast. The main task is to minimize the energy demand and lower the price of the final products with partial heat recovery. These changes will require system modifications. One of the most popular and effective methods that can be used in this case is heat process integration with Pinch Technology. In this study, a reference system was simulated with a mathematical model and analyzed for waste heat streams.This paper suggests the redesigning of a drying system for production of active dry yeast.  Selected streams that satisfy conditions for heat process integration were involved in the evaluation for a better solution. Two different scenarios were proposed as possible solutions. The suggested solutions are retrofit designs of Heat Exchanger Networks. These Heat Exchanger Networks include already installed heat exchangers as well as new heat transfer units. The selection of better design was made with economic analysis of investment. The proposed scenarios of the analyzed sub-system give improvement in heat energy recovery. The best determined solution reduces the cost and thus has the highest profitability, but not the highest heat energy recovery.

Supply Equipment

Vehicles are developing in the direction of energy-saving and electrification. suspension has been widely developed in the field of vehicles as a key component. Traditional hydraulic energy-supply suspensions dissipate vibration energy as waste heat to suppress vibration. This part of the energy is mainly generated by the vehicle engine. In order to effectively utilize the energy of this part, the energy-regenerative suspension with energy recovery converts the vibrational energy into electrical energy as the vehicle’s energy supply equipment. This article reviews the hydraulically powered suspension of vehicles with energy recovery. The importance of such suspension in vehicle energy recovery is analyzed. The main categories of energy-regenerative suspension are illustrated from different energy recovery methods, and the research status of hydraulic energy-regenerative suspension is comprehensively analyzed. Important factors that affect the shock-absorbing and regenerative characteristics of the suspension system are studied. In addition, some unresolved challenges are also proposed, which provides a reference value for the development of energy-regenerative suspension systems for hybrid new energy vehicles

The Impact

Exhaust gas heat utilization in the form of Thermal Energy Recovery (TER) has attracted a major interest due to its potentials with Internal Combustion Engines (ICE). Recovering useful energy, for example in the form of electrical power from the engine exhaust waste heat could benefit in the form of direct fuel economy or increase in the available electric power for the auxillary systems. The methodology in this paper includes the assessment of each waste heat recovery technology based on the current research and development trends for automotive application. It also looked into the potential for energy recovery, performances of each technology and factors affecting its implementation. Finally, the work presents an Electric Turbo Compounding (ETC) simulation using a Ford Eco-Boost as a baseline engine modeled with the 1-Dimensional AVL Boost software. A validated 1-D engine model was used to investigate the impact on the Brake Specific Fuel Consumption (BSFC) and Brake Mean Effective Pressure (BMEP) at full load. This paper presents some reviews on the turbo-compounding method and also the modelling efforts and results of an electric turbo-compounding system. Modelling shows that the turbo-compounding setup can be more beneficial than turbo-charging alone.

Recovery System

The Rankine Cycle Energy Recovery (or RACER) is an unfired waste heat recovery system designed for use aboard U.S. Navy gas turbine powered ships. The system converts waste heat from the exhaust of the main propulsion gas turbines into useful shaft horsepower and is currently planned for installation aboard the new DDG-51 class of ships. The design philosophy used in determining an overall system concept to minimize manning yet maximize availability, reliability and fuel savings is discussed. The paper also describes the trade-off analyses made to size the system in relation to overall fuel saving and gives a brief summary of the test programs to verify the system prior to ship installation.

Heat Recovery System

As the ever-changing world continues to desperately look for alternative energy sources in the midst of an energy crisis, new technologies to recover power are revealing themselves and being implemented all across the globe. Most power plants are looking for more sustainable sources of energy over the long term. One such technology being adopted now by a lot of enterprises are Energy Recovery Systems. These systems work to retain and reuse energy that would otherwise be lost to the atmosphere after a certain process. They are sustainable and require comparatively lower capital. The objectives of this project revolve around the modelling of a Waste Heat Recovery System (WHRS) for a heat-intensive manufacturing process. The heat, which would otherwise be lost to the atmosphere, is trapped and converted by a heat recovery unit into reusable energy. The main principle on which such a system would operate is The Rankine Cycle, an idealized thermodynamic cycle. Successful implementation of such an energy recovery system would not just boost energy efficiency but also reduce operational costs. The modeling and simulation of the heat recovery system are done on an open-source chemical process flow software known as DWSIM. An analysis of this heat recovery model shows an increase of 19.66% in the energy efficiency of the manufacturing process. Heat recovery systems also have great benefits for the environment, as they reduce the emissions of greenhouse gases by such manufacturing plants and help reduce global warming.
