  • CHP efficiency for biogas

    Combined heat and power plant efficiency is a function of the conversion efficiency of the energy in the fuel gas to useful energy in the form of electricity and heat. A combined heat and power (CHP) plant is typically a reciprocating gas engine that uses the energy in the gas to drive a crank shaft. The crank shaft turns an alternator to ...

  • 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 ...

  • CHP gains stature as efficiency measure

    Combined heat and power is a form of alternative energy that has been available for many decades. Yet it’s remained below the radar screen in policy discussion about our energy future. However, it appears to be gaining new stature as lawmakers and regulators seek ways to make energy use more efficient.Also called cogeneration, the technology creates both electricity and heat in one unit. Most ...

  • Greenstars portable monitoring for CHP and flares

    Greenstar’s award-winning KTK landfill site in Kilcullen, Co. Kildare, is unusual in Ireland in that it has three gas engines feeding electricity to the grid and two flares. In Ireland, while flaring is common, engines are not. The flares are run in tandem with engines so that if an engine is ramped down for repair or service, the flare ramps up automatically. All are supplied by 122 ...

  • Maize Products Biogas CHP Gujarat - Case Study

    With a legacy of over seven decades, Maize Products has exemplified corn milling from a modest 1 tonne/day of crushing in the year 1941 to a crushing of 650 tonnes/day today. Honoured with the National Award for Import Substitution in the year 1976, Maize Products actively contributes in the research and development of starch & starch derivatives. Harnessing renewable energy, Maize Products ...

  • Qualifying Combined Heat and Power (CHP) activity

    The EU 2002 draft and 2004 final CHP Directives propose qualifying CHP activity with the quality norm. This norm benchmarks the energy efficiency of CHP plant outputs on external reference power and heat efficiencies. Because the quality norm amalgamates cogeneration and condensing activity its application entails particular perverse effects for high-quality and adapted scale investment in CHP ...

  • How to generate an accurate load profile for CHP

    If you fail to accurately work out your site's energy demands, you'll give rise to a cogeneration system that underwhelms when served up to your customer. That's why load profiling is the key ingredient in successfully specifying your cogeneration project and ensuring that you meet your clients' expectations. Generating an accurate ...

  • Deploy CHP in China that Utilize Coke Oven Gas for Fuel Feedstock

    Combined Heat and Power systems offer significant energy efficiency opportunities in Partner countries. The United States will lead this project in which key turbine components will be provided to Chinese industry along with training in these systems. Once systems are operable, a savings of approximately 1.2 million tons of CO2 per year is ...

  • CHP Sizing: why Goldilocks style guesswork isn`t enough

    In storyworld, Goldilocks would stroll into the plant room and state "this CHP's too big", "this CHP's too small", "ahh ... this CHP is just right" – happy ever after. The end. But in the real word, the tricky issue of CHP sizing isn't quite so straightforward. This can be a tough lesson for some ...

  • Biogas CHP supplies in Uruguay electricity and heat case study

    Dreyer & Bosse Kraftwerke as a seasoned manufacturer of CHP (Combined Heating and Power) has provided a complete CHP system of series Vita for generating heat and power for a wool producer in Uruguay. The biogas cleaning system including biogas cooler and activated carbon filter were ordered and delivered as well for a smooth operation. There are 3.9 millions of sheep at this farm, about 40% ...

  • Dreyer & Bosse deliver renewable energy CHP project to Sofia in Bulgaria

    The Sofia council decided to invest in renewable energy to make use of the many tons of biowaste (vegetative material),  20,000 tons per annum, from the waste removal collections that take place daily in Sofia and surrounding area. To make this possible it was decided to go for wet fermentation where the substrate or raw material ferments and the biogas is collected. After three weeks the ...
