Crown Capital Eco Management – Biomass Boiler Addresses Environmental Concerns

http://crownecocapital.livejournal.com/363.html

Crown Capital Eco Management Indonesia – The heavily forested city of Ketchikan, Alaska, is built on rock and surrounded by water. Every commodity that comes into Ketchikan must arrive by sea or air. The use of fuel oil is problematic for both economic and environmental reasons because the oil must be obtained and refined elsewhere and transported (using additional fuel). What’s more, fuel oil is subject to price instability.

Southeast Alaska Discovery Center in Ketchikan, which provides information to more than a million visitors each year, is the site of a pilot biomass boiler system now coming to life. Two oil-fired boilers serving the 250,000-sq-ft center were replaced with a highly efficient system fueled by local wood. Manufactured by Hurst Boiler & Welding Company Inc., the hot-water boiler was custom-designed to fit within very limited indoor space.

Under the direction of E. Dane Ash, project manager for Tyonek-Alcan Pacific LLC, the biomass boiler system was developed with Hurst representative Gregory W. Smith of Global Energy Solutions Inc. to address environmental concerns, as well as issues related to building space, fuel costs, comfort, reliability, and simplicity of operation.

 

The new boiler is located on the lower level of the Discovery Center, which requires heating for a minimum of nine months a year. Local wood densified into fuel pucks is delivered to an elevated walking-floor storage bin in a vestibule area built to protect against excessive moisture. (The biomass-fired boiler can burn any wood product with up to 50-percent moisture content.) An auger moves pucks from the storage area to a metering bin and into the boiler. Freezing is not an issue because the walking floor easily breaks up any frozen contents.

The boiler system was designed to highlight how biomass can reduce or eliminate the use of fossil fuels. Visitors can see the boiler operate through specially designed windows. In the hall just outside of the boiler room, the noise level and ambient temperature is consistent with the rest of the building.

 

Savings

 

Fuel costs have been cut by two-thirds. The densified pucks are used with almost no residual ash; eventually, however, tree clippings from the Ketchikan walking trails will be ground and fed into the boiler, eliminating the need for transport to a landfill, burning, and other methods of disposal.

 

The Boiler

 

The Hurst S100 Series Fire Tube 27 HP Hydronic Water Heating Boiler features a pre-heater to optimize combustion and an underfeed stoker with dry-ash-removal system.

 

Results

 

The system easily can be replicated for heat or heat/power generation up to 20,000 kw. In June 2011, Smith served as a keynote speaker for the fifth annual Native American Economic Development Conference in Anaheim, Calif., where he described the initiatives being implemented in Ketchikan and shared success stories of biomass-fired boiler systems installed on institutional campuses and in manufacturing facilities throughout the United States, particularly in challenging and remote locations. Systems include municipal solid waste, as well as woody biomass for steam production and steam to power.

  1. Growing evidence of great climate change scams

    HERE’S some news to put a great big smile on your face: apparently, Arctic sea ice volume is up by 50 per cent. Have you cracked open the champagne yet? Did you ring all your mates? Me neither. In fact, to be honest, I couldn’t care less whether it’s up 50 per cent or down 50 per cent. It’s just weather doing what weather does – changing all the time. But you wouldn’t guess this from the way it is reported in the media. Sceptical websites are presenting it as a vindication of their longstanding claim that all the fuss about catastrophic, man-made global warming has been greatly overdone. Warmist news outlets (“a rare piece of good news”, declared the BBC) are greeting it as a sign of hope that maybe there is time left for us to save the planet from the Greatest Threat It Has Ever Known.
