  • Utilizing Waste Heat For Power

    Continuous duty gen-sets provide base-load power generation in diverse applications around the globe. However, high fuel costs and engine maintenance are pain points felt by operators. A low-maintenance path to significant fuel savings and lower emissions is what the U.S. Department of Defense (DOD) had in mind when they approached ElectraTherm to integrate the company’s Green Machine waste ...

  • Is waste heat the silver bullet?

    The energy industry tends to get stuck on certain words. Silver bullet is one of them. Insiders and policymakers often like to say there is no silver bullet to fix US energy woes. We need a portfolio of solutions – renewables, efficiency, smart grid, transmission expansion, coal sequestration, etc. That may be true, but Tom Casten begs to differ. Casten is a bit of a rock star in the field of ...

  • Exergy or the entropic drive: waste heat and free heat

    The dissipation of exergy is conventionally held to be the inference of the entropy growth. In this conventional perspective, the universe is running down towards equilibrium or heat death. Recent cosmological findings of 1998–2000 give empirical evidence that the universe is instead moving away from equilibrium while its entropy increases. We can better comprehend this non–equilibrium world by ...

  • Thermo–economic analysis of heat pipe heat exchanger for waste heat recovery in thermal systems

    Thermo–economic analysis of Heat Pipe Heat Exchanger (HPHE) for waste heat recovery in thermal systems using the P1–P2 and NTU methods is presented. The optimum effectiveness of a HPHE is given as a polynomial equation, whereas the net savings and payback period are given in closed form to enable the HPHE designer to determine the optimised values directly. In addition to this, exergy analysis of ...

  • CDQ waste heat boiler for iron and steel industry manufacturer

    Energy use is additionally a major supply of emissions from the iron and steel industry, making energy efficiency improvements a lovely chance to reduce both emissions of pollutants and greenhouse gases. The global steel industry has recently taken the lead on developing future low-carbon iron and steelmaking technologies. Waste heat boiler ...


  • Case-study - Utilising waste heat for water production and climate control

    Water purification is needed to produce high quality water for consumption, agriculture and industrial needs. Conventional water treatment processes, like distillation and reverse osmosis, consume vast amounts of energy. However, there is a large potential for significant reductions in energy consumption and CO2 emissions in this sector. It can be achieved by the exploitation of waste heat for ...

  • Heat recovery from wastewater

    Heat recovery from gray water is particularly important in water-intensive industries such as pulp and paper plants, dairies and breweries. Rather than flushing used water down the drain, consider whether a heat exchanging system can help you put that energy to work in your process again. Most plant operators arc aware of the need to save money and reduce the environmental impact of their plant ...

  • Enhancing the dynamic performance of electricity production in steam power plants by the integration of transient waste heat sources into the feed-water pre-heating system

    Since the deregulation of the energy market the enhancement of steam power plant's dynamic performance has become more and more important. Nowadays, peak load is a profitable product at the energy stock markets if it can be provided reliably. This is in contrast to many power plants running constantly at full load. A very promising technique to improve the peak load capability of such power ...

  • A study on the thermodynamic analysis of a cascaded latent heat storage system over the single storage tank system for diesel engine waste heat recovery

    This article presents the comparison of performance of a cascaded Latent Heat Storage (LHS) system over the Single Storage Tank (SST) system for heat recovery from a diesel engine. The energy and exergy saved and efficiencies during the charging process are evaluated and reported using actual system data. The discharge process is analysed with a case study and it is concluded that it is possible ...

  • Much light, little heat efficiency

    Energy efficiency in the US is much light and little heat – literally.  Government policy pays a great deal of attention to saving electricity, but focuses little on the thermal energy we waste.  “Policy is electricity-centric in the US. Unless you are making kilowatts, the most efficient investments are off the radar,” said Rob Thornton, president of the ...
