Waste heat recovery

Context

Belgrade's district heating (DH) system is one of the largest in Europe with a total network length of 1420 km and capacity of over 2800 MW. The majority of the network is run on the natural gas boilers and fuel oil boilers with no waste heat from cogeneration or other sources being used and very little renewables (0,75% of capacity). Energy efficiency of the building stock is quite low, and the intensity of energy consumption is high. The city needs harmonized approaches to efficiency.

Eco-Tech Ceram (ETC) is a European Small Enterprise focused on the industrial energy efficiency market.  EcoStock, using refractory ceramic made from waste. This solution contributes to two of the European 2020 objectives: 20% reduction of greenhouse gas emissions and 20% reduction in primary energy use, by recovering and reusing their waste heat
 

The objective of Cluster Solaire is to help strengthen skills and develop industrial expertise in the field of renewable energy. By coordinating professional organizations, manufacturers, researchers and academics, Cluster Solaire combines multiple resources and skills, encourages cooperation, and promotes development of synergies between public and private stakeholders. Cluster Solaire supports green energy companies across Morocco and the MENA region in their effort to design new technologies that reduce carbon emissions and preserve the planet.

IIGE is a research institute that promotes development, innovation and transmission of technology focused on energy efficiency and renewable energy. The institute aims to contribute to the sustainable development of the Ecuadorian society, through the implementation of energy efficient and energy renewable policies and projects.

The Global Environment Centre Foundation (GEC) is an entity that supports the UNEP’s International Environmental Technology Centre (IETC), based in Japan. GEC is dedicated to the transfer of environmentally sound technologies, in both developing countries and countries with economies in transition. The foundation aims to contribute to Japan’s international efforts on the environment, sharing project collaborations as well as promoting Japan’s rich conservation knowledge and experience in developing nations.

Desalination has been a practical solution to water shortage problems encountered in numerous countries in the world. Several commercial scale desalination plants have been designed built and operated such as multi-stage flash (MSF) type the multi-effect desalination type the membrane-based reverse osmosis (RO) plants hybrid RO and MSF plants and Ion exchange systems.

Researchers at Santa Clara University have designed and tested a Concentrated Solar Power (CSP) device on a residential scale can generate electricity and use rejected heat for many applications including domestic hot water space heating/cooling and absorption refrigeration. This system uses a combined thermoelectric and heat system with a proprietary low-profile solar tracker described in docket 12-S01.

The invention concerns devices for water storage heating and delivery. A storage water heater of the invention provides an amount of unmixed recently heated water from an internal small volume during a draw along with water from a main volume. When water is drawn from the storage water heater an amount of recently heated water substantially unmixed with the remaining volume of the tank is drawn along with heated water from the remaining volume.
