  • Thermodynamic and exergy efficiencies of magnetocaloric energy conversion utilising industrial waste heat

    An investigation under which conditions industrial waste heat utilised with magnetic energy conversion machines can be a possible alternative to conventional energy conversion technologies is presented. The application of a numerical model leads to the thermodynamic efficiency, the exergy efficiency, and approximate values of the total mass and the total volume of a magnetic energy conversion ...

  • Advanced Application of Product Gases of Thermal Conversion of Biomass and Waste; Integration With the Fischer-Tropsch Synthesis

    The Netherlands Energy Research Foundation (ECN) is studying the advanced application of product gases from the thermal conversion of biomass and waste (B&W). The Fischer-Tropsch (FT) synthesis is the most promising as it affords diesel-like fuels of high quality and free from sulfur and aromatics. A slurry bubble FT reactor with an iron catalyst is the most suitable for B&W syngases. To optimize ...

  • Thermodynamic analysis of efficient recovery and utilisation of waste heat resources during sintering process

    Efficient recycling and utilisation of waste heat resources are among the primary methods in saving energy during sintering process, as waste heat resource recycling and utilisation are essentially energy conversion process. The purpose of this study is to analyse energy conversion and utilisation during the sintering process, and waste heat resources in each subsystem during the sintering ...

  • What 2017 holds for Energy from Waste in the UK

    The UK’s EfW industry has enjoyed two decades of stable investment under the public private partnership (PPP)/public finance initiative (PFI) regime. This has led to a reduction in the amount of biodegradable household waste sent to landfill via the construction of local authority-backed EfW plants and contributed to an increase in recycling rates by incorporating facilities that remove ...

  • Amit Kumar and Gregory Stephanopoulos on turning waste gases into biofuels

    Research conducted by Kumar, along with a team led by Professor Greg Stephanopoulos, looks to the future of emissions reduction and recycling. Original story at MIT News One of the most promising ways to combat carbon emissions is to transform those emissions into ...

  • Effects of combustion efficiency on an Otto cycle

    This paper explains how the combustion efficiency influence the performance of an irreversible Otto cycle under conditions of varying fuel-air ratio. The irreversibility of Otto cycle comes exclusively from the expansion and compression processes. It is assumed that some fraction of the fuel's chemical energy cannot be fully released inside the engine because of incomplete combustion. Amount of ...

  • The shifting landscape for renewable energy in the UK

    The UK Government has a commitment to reduce the UK’s greenhouse gas emissions by at least 80 percent by 2050 (from 1990 levels). As a result, the UK landscape surrounding renewable energy is shifting rapidly to help deliver a low carbon future. Recently, there have been a number of national consultations which are likely to have a significant bearing on the future viability of non-fossil ...

  • Using Venturi Scrubber Technology for Syngas Cleaning

    As part of our nation's program to reduce dependence on fossil fuels, various gasification technologies are being applied. These processes take renewable organic material and, through the application of heat and pressure, convert the materials into syngas for further use. Arguably, in nearly all of these processes, the most critical design aspect is the reliable and efficient removal of ...

  • What is energy recovery?

    Processes like incineration and anaerobic digestion not only provide sources of energy, but they also reduce waste volume The term “energy recovery” often is applied only to a narrow number of methods for converting wastes into energy, when in fact it applies to a broad range of technologies used to create heat, electricity, or fuel. Energy recovery gives ...

  • Bio-SNG featured in energy world in February 2011

    The use of bio-fuels for heating and lighting pre-dates the use of fossil fuels by thousands of years. However, unlike with fossil fuels, a systematic knowledge of the challenges posed by solid bio-fuels is not as widely understood, a fact attributable to the exponential acceleration of fossil fuel usage as global demand increased during the industrial revolution. In the wake of this, producers ...

  • CHP: Not the Brad and Jen of energy, but….

    I hesitate to start this blog with the words “combined heat and power.”  You might stop reading. Okay, so it’s not the Brad and Jen of energy. (That would be solar and wind.) But what it lacks in glamor, it makes up for in constancy and results. It’s an old guy, been around for about a century. And while its name might not sound green, it offers an extraordinarily ...

  • Saving Renewable Energy for a Rainy Day

    Despite advances in renewable energy technologies, one of the largest hurdles in their widespread adoption has been their intermittent reliability. Energy is only useful if it is available as the grid demands it, which is why concerns about carbon emissions are overridden in favor of the more dependable oil, coal and gas for baseload power. In order for renewable sources such as wind and solar ...

  • Renewable Energy - A Key Solution to End Global Warming

    Scientists have spent years trying to find the causes of global warming leading to significant changes in the world’s climate. Their research shows that several factors have contributed to the rise of earth’s temperature and altering of natural cycles and actions. One key reason is excessive emission of greenhouse gases like, methane and carbon dioxide (CO2) in the atmosphere. These ...
