The research and development organization from central Poland is looking for partners for to project. The project is focus on the management of waste heat from industrial installations. In order to the management of waste heat from industrial installations that is lost irretrievably by discharging it to the environment, the organization propose the exchange of the thermal energy of waste heat into useful electric energy with the use of thermogenerators. Description of the project: 1. Obtaining the maximum value of the electric current power from the heat flux under the conditions of energy balance in the system. 2. Providing high-temperature heat energy to the hot side of the thermogenerator, taking into account the compensation of uneven temperature distribution on the surface of the waste heat source and maintaining the nominal operating temperature of the thermogenerator. 3. Conversion of DC output waveforms of thermogenerators into power grid parameters with the possibility of working in on-grid and off-grid (island) systems and ensuring that the operating point is maintained at the maximum power of the thermogenerator. 4. Effective heat collection from the cold side of thermogenerators ensuring minimum energy consumption. 5. Integration of system elements in the form of a control system that monitors the condition and parameters of the system and enables cooperation with external systems. The following aspects have been developed and prepared: -The stand for testing of thermogenerator systems. The station includes a simulated waste heat source with temperature control and an external cooler with a water reservoir. The stand enables the determination of the characteristics of thermogenerators using two methods. - Two model systems of thermogenerator sets with different methods of heat energy supply, each with a power of 160 W. -A single-phase power electronic converter with a power of 1 kW, feeding energy to the power grid. The research and development organization disseminates the idea in the industrial environment. The organization has held conversations with several companies, including the glassworks and cement plant interested in this solution. The research and development organization has experience with systems of thermogenerator sets shows that the main problem of this type of installation is the reception of energy from the cold side of thermogenerators. The organization intends to use an adsorption chiller in the project. Such a unit provides cooling at the power consumption acceptable for the system. An external fan cooler cools the unit for ambient temperatures not exceeding a dozen or so degrees; it practically does not use electricity.
