“…1 In addition to automotive applications, the focus is shifting towards the stationary systems of metal forming industry because of the huge heat fluxes which are available and less restrictive conditions for setting up a system compared to mobile application in automobiles, e.g., the geometric and temperature conditions in a car. Kuroki et al 2 developed and tested a TEG gaining heat from a continuous casting line.…”

The hot forming process of steel requires temperatures of up to 1300°C. Usually, the invested energy is lost to the environment by the subsequent cooling of the forged parts to room temperature. Thermoelectric systems are able to recover this wasted heat by converting the heat into electrical energy and feeding it into the power grid. The proposed thermoelectric system covers an absorption surface of half a square meter, and it is equipped with 50 Bismuth-Telluride based thermoelectric generators, five cold plates, and five inverters. Measurements were performed under production conditions of the industrial environment of the forging process. The heat distribution and temperature profiles are measured and modeled based on the prevailing production conditions and geometric boundary conditions. Under quasi-stationary conditions, the thermoelectric system absorbs a heat radiation of 14.8 kW and feeds electrical power of 388 W into the power grid. The discussed model predicts the measured values with slight deviations.

“…As summarized in Table 1, about 40% or more of the energy consumed in a marine engine is emitted in the form of waste heat, 75% of which is discharged directly to the atmosphere in low-temperature exhaust gas and jacket coolants [2]. Recent research introduced various technologies including an organic Rankine cycle (ORC) and a thermo-electric generator (TEG) to convert engine waste heat into useful power [3].…”

Dual parallel organic Rankine cycle (ORC) system for high efficiency waste heat recovery in marine application

et al. 2015

A dual parallel organic Rankine cycle (ORC) system is proposed for the efficient waste heat recovery of marine applications, which present a relatively large variation of waste heat relative to sailing conditions. Simulations for single and dual ORC systems are conducted with a wide range of heat input. The performance results are compared to evaluate the benefits of the proposed dual configuration. Annual total power outputs produced by single and dual ORCs are calculated to assess the appropriateness of applying the dual ORC to a marine engine by using four models of fuel consumption distribution based on the actual sailing data of a container ship. Results demonstrate the ability of dual ORC to produce more total power output than the single ORC.
