  • Case study - Heat exchanger retrofit

    Overview A manufacturer of insulation films for the electronics industry needed to evaluate the capabilities of four existing oxidizers that treated emissions from its coating lines. The company was concerned that, due to oxidizer deficiencies, it would not meet regulatory requirements. The oxidizers had been manufactured by two different companies. One of them was no longer in business; ...

  • 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 ...

  • Combined Heat and Power – Questions and Answers

     1. What are the benefits of CHP for business?   combined heat and power (CHP) is a well-proven technology, recognised worldwide as a cleaner alternative to traditional centralised generation. Its long-term future in the global energy markets is secured by CHP's ability to provide a multitude of financial, ...

  • Invisible Structures’ Products vs. Heat Island Impacts

    As many city residents can tell you, cities can be very hot places during the, summer. On warm summer days, the air in a city can be 6-8°F hotter than its, surrounding areas. Scientists call these cities "Urban Heat Islands." What, causes this to happen? There are fewer trees, shrubs, and other plants to shade buildings, intercept, solar radiation, and cool the air by "evapotranspiration." ...

  • Small-scale heat and power at B.C. mills

    Fred Scott introduced the B.C. Bioenergy Network (BCBN) as an alliance between Pristine and Nexterra Energy Corp. BCBN is a network of 15–20 individuals, with 10 MW power plants located across B.C. at mill operations in forest communities. Nexterra has developed a proprietary gasification technology that “takes wood waste material and [produces] clean burning synthetic gas or syngas,” Scott said. ...

  • Utilisation of deep geothermal energy for heating purposes

    The Hot-Dry-Rock-(HDR) technology allows a location-independent utilisation of geothermal heat, because aquifers in deep formations, i.e. layers filled with water, are not necessary. The flow paths for the circulating water in a depth of 4 km are created by hydraulic fracturing of existing gaps. Due to the fact that this new technology is quite cost-intensive, high annual load duration of the ...

  • Opening markets for CSP – the industrial heat application

    Heavy industry can be a viable secondary market today for CSP producers, but questions remain on whether start-up costs are justifiable for industrial users, and how reliable CSP can be for processes that can't pace production by the sun. Solar thermal heat implies steam, and industries that need steam include refining, food processing, wood-working, desalination and chemicals, among others. ...

  • Customers problem: steam injection tank heating

    Northwood pulp and Timber Company in Prince George British Columbia, was plagued with a problem of violent vibrations and banging when heating a large volume paper machine chest with a conventional steam sparger. The tank walls were lined with ceramic tiles which were cracking, sections were coming off the wall due to the vibration from the collapsing steam bubbles. Komax Solution: Bill Neville, ...

  • Floating nuclear power plants

    Nuclear energy, in comparison with other modes of energy generation such as hydro, thermal and non-conventional sources, has high energy density with little environmental pollution or greenhouse gas emissions. The methodologies to check the problems of nuclear radiation hazards and waste associated with this technology are continuously being developed towards perfection. The nuclear plants are ...

  • Exergoeconomic optimisation of steam power plant

    The second law of thermodynamics combined with economics forms a powerful tool for systematic analysis and assessment of energy systems. This paper presents an exergoeconomic optimisation of 50 MW steam turbine power plant associated with a large fertiliser industrial unit through Thermoeconomic Evaluation and Optimisation (TEO) method, and identifies the losses in various components. As the ...

  • Heat as a by–product or sub–product of CO2 storage in mafic and ultramafic rocks

    Since carbonates are at a lower energy state than free CO2, storage through carbonation of silicate rocks is thermodynamically favoured and proceeds spontaneously by releasing heat. In an in–situ CO2 injection site, the heat released in these exothermic reactions can be exploited in a geothermal power–plant, effectively contributing ...

  • Heat recovery and energy efficiency, improves profitability and reduces CO footprint

    Using latest technology in combustion of oil and gas can provide significant savings in overall energy consumption. Modern oxygen control that compensates changes in ambient temperature and fuel qualities can increase energy efficiency up to 3%. By adding the usage of hot combustion air another 2-3% can be saved. Modern burner technology without mechanical linkage, operating with accurate ...

  • As Global Demand for Electricity Grows, Geothermal Energy Heats Up

    January 9, 2017 — At 2:46 p.m. local time on Friday, March 11, 2011, Japan was rocked by the largest earthquake ever to strike its shores. The 9.1 magnitude quake triggered a devastating tsunami that killed more than 15,000 people. It also took out the back-up emergency generators that cooled the reactors at the Fukushima Daiichi nuclear power plant complex, causing a series of ...

  • Cellulosic biofuel plant - Case study

    Cellulosic Biofuels meets National Emission Standards for Hazardous Air Pollutants A multitude of new cellulosic bio-fuel processing facilities across the country are now faced with having to meet new National Emission Standards for Miscellaneous Organic Chemical Manufacturing. One specific NESHAP is 40 CFR part 63, subpart FFFF. The applicability of meeting this NESHAP is: A facility must be a ...

  • The Aberdeen Heat and Power district energy schemes - Case Study

    District energy schemes seemed to be the right decision for the Aberdeen City Council (ACC). They had conducted a study of its housing stock and established that the multi-storey buildings (of which they have 59 in Aberdeen) were too expensive to heat. These buildings also had lower energy ratings, thus people living in them were subject to high energy bills. In 2002, as one of the results of the ...

  • 24kW Ground Source Heat Pump In Essex - Case Study

    The space heating and hot water for this property was previously done by an oil boiler. The client was considering a ground source heat pump in order to lower running costs and benefit from tariff payments under the Renewable Heat Incentive (RHI). Better Planet carried out a room by room heat loss calculation. This is required in order to size the heat pump ...


  • Ethanol, Biomass Plants Planned for Minnesota

    Proposed facilities prepare to turn organic residuals into electricity, methane and synthesis gas “with minimal emissions and more profit.” AN ETHANOL plant in Little Falls, Minnesota is building an on-site gasifier that will convert wood waste and distiller's grains to gas for generating electricity and heat to serve the needs of the Central Minnesota Ethanol Cooperative. At the same time, ...

  • Advanced plants to meet rising expectations for nuclear power

    Nuclear power produces 15.2% of the world's electricity. Many countries are planning to either introduce nuclear energy or expand their nuclear generation capacity. Design organisations are incorporating both proven means and new approaches for reducing the capital costs of their advanced designs. In the near term, most new nuclear plants will be evolutionary design, often pursuing economies of ...

  • Quick response to assist nuclear power plant

    A US nuclear plant and their engineering contractor were faced with an unexpected challenge in the course of design work regarding installation of an emergency steam dump sparger in the plant’s Low Pressure (LP) condenser. During pre-outage reviews of the planned installation, it was found that an existing partition plate running nearly the length of the condenser was obstructing access. ...
