The Haney Group Article Code 85258080733: Better boiler c...

Source Link: http://www.environ mental-expert.com/ news/better-boiler -control-could-cut -business-energy-b ills-by-30-or-more -389908 Gain control of your boiler to make quick energy savings of 30% or more says ENER-G Controls Inefficient boilers, where water is re-heated unnecessarily, mean business energy costs can be more than 30% higher than they should be, according to ENER-G Controls. 'Your typical boiler is unintelligent and will often fire up unnecessarily, when there is still sufficient heat within the system', explained, Steve Berry, General Manager for ENER-G Controls. 'When this happens the boiler re-heats water that is already sufficiently heated and the excess heat is wasted up the boiler flue. This is commonly called dry-cycling and can add more than 30% to the cost of an organisation's heating bill. ' ENER-G Controls has introduced the E-MAGINE Boiler Optimiser that makes boilers demand driven. As such, the boiler only runs when it needs to and at the temperature required to satisfy demand, thus saving energy and unnecessary wear of the equipment. Steve Berry added:'Heating and hot water accounts for more than a third of UK business energy consumption, therefore boiler control is one of the quickest and easiest ways an organisation can reduce energy bills and make energy savings to comply with environmental targets on carbon reduction. Typical payback on investment will take 12 to 24 months, depending on the size of the system. The technology also qualifies for Enhanced Capital Allowances, enabling businesses to offset a portion of the purchase cost against tax. Or if businesses would prefer they can take out an energy performance contract which may provide a better option in receiving guaranteed savings from day one'. ENER-G Controls is providing a 14-day proving period of its E-MAGINE Boiler Optimiser to energy intensive businesses to demonstrate the actual reduction in fuel cost and carbon savings that can be made. The E-MAGINE Boiler Optimiser is compatible with most types of boilers. These can be sequence controlled and duty-rotated to ensure even boiler running hours. further information here: http://thehaneygro up.org/ http://ireport.cnn .com/docs/DOC-1022 917 http://www.slidesh are.net/annheir17/ haney-gruppe-artik kelen-koden-852580 80733  (Aug 24, 2013 | post #1)

Transforming China’s Grid: Will Coal Remain King in China...

Transforming China’s Grid: Will Coal Remain King in China’s Energy Mix? http://theenergyco llective.com/micha el-davidson/251931 /transforming-chin a-s-grid-will-coal -remain-king-china -s-energy-mix Coal has been the primary fuel behind China’s economic growth over the last decade, growing 10 percent per year and providing three quarters of the nation’s primary energy supply. Like China’s economy, coal’s use, sale and broader impacts are also dynamic, changing with technology and spurring policy interventions. Currently, China’s coal sector from mine to boiler is undergoing a massive consolidation designed to increase efficiency. Coal’s supreme position in the energy mix appears to be unassailable. However, scratch deeper and challenges begin to surface. Increasingly visible health and environmental damages are pushing localities to cap coal use. Large power plants with greater minimum outputs are shackling an evolving power grid trying to accommodate new energy sources. Further centralization of ownership is rekindling decade-old political discussions about power sector deregulation and reform. This unique set of concerns begs the question: how long will coal remain king in China’s energy mix? Managing conflicts between security of supply and the environment China faces the typical conundrum of any large coal-rich nation: as an energy source, coal has an unrivaled security of supply while also being the dirtiest to extract and use. However, whereas other countries enjoy some amount of fuel diversity, China’s resource endowments in other fossil fuels are severely limited (see figure). China is home to perhaps the world’s largest deposits of shale gas, but these resources are still many years away from commercial exploitation. To meet rising electricity demand, China is rapidly exploiting its renewable and hydropower resources: by 2020, China aims to have 200 gigawatts (GW) of wind, 50 GW of solar, 30 GW of biomass, and 300 GW of hydro. Nuclear is expected to increase six-fold, to 80 GW. Yet, even with these massive additions of non-fossil energy sources, China still plans to add 50 GW of coal-fired capacity every year in order to keep up with the projected growth in energy demand. At the same time, environmental and health damages driven by China’s rampant coal use are increasingly apparent. Cancer is the leading cause of death in Beijing, with lung cancer the most common form. Monitoring PM2.5 is now like checking the weather report – a daily necessity for city-dwellers. A recent study pegged coal’s use in northern China to heat homes as contributing to an average loss of 5 years in life expectancy. In the long term, the International Energy Agency’s 450ppm scenario for climate stabilization calls for an 80% reduction in CO2 emissions from coal-fired electricity in China by 2035, compared to business as usual, a goal which could only be met with a drastic reorganization of the power sector and significant technological advances in carbon capture. China is currently experimenting with local emission trading schemes to complement administrative energy efficiency measures. As I blogged about earlier, these face a host of challenges before they can really take off. read more: http://thehaneygro up.org/blog/ http://thehaneygro up.org/index.html  (Jul 24, 2013 | post #1)
