Public Ins5tu5on Boiler Systems Messersmith boiler systems are installed in schools, universi5es, hospitals, state facili5es and many other public ins5tu5ons Messersmith Wood Chip Boiler Systems displace the use of fossil fuels while providing clean, reliable energy as heat, hot water, and steam Current installa5ons range in building footprints from 15,000 sq. [. to 1.5 million square feet Single and mul5ple buildings En5re Campuses District Energy Combined Heat & Power

Boiler Room Equipment

Boiler Room Equipment Fuel Handling The Messersmith Traveling Augers pull wood chip fuel out of a chip bin to convey to the biomass boiler system

Boiler Room Equipment Fuel Handling A series of belt conveyors transfer the fuel from the chip bin to the fuel metering bin

Boiler Room Equipment Fuel Handling The fuel metering bin accepts fuel from the belt conveyors and meters the fuel that gets transferred into the combus5on system

Boiler Room Equipment Fuel Storage Fuel storage bins can be designed to be at or below grad e Semi trailers with a live bo]om walking floor empty the fuel into the storage bin where it is removed by the Messersmith Traveling Auger

The Messersmith Combus5on System burns a variety of biomass fuels ranging from 3% to 50% moisture content (wet basis) Boiler Room Equipment Combus5on

Boiler Room Equipment Controls Messersmith boiler systems come with PLC controls designed for your facility Remote Monitoring & Diagnos5cs Op5onal Building Automa5on Controls

Benefits of Biomass Boiler Systems There are many economic, community and environmental benefits to burning wood chips: Significantly lower your facili5es energy cost Create jobs in your local community Eliminate waste wood that could otherwise go to a landfill Decreased reliance on fossil fuels Stable fuel cost that doesn t fluctuate like gaseous fuels Decrease your facili5es carbon footprint Wood chips harvested from managed 5mber stands are a carbon neutral fuel because the CO 2 produced by their use is reabsorbed by the ecosystem through regrowth of the forest.

Wood Chip vs. Propane Cost Wood Chips @ $45/ton = Propane @ $0.56/gallon ($0.15/liter) Wood Chips @ $50/ton = Propane @ $0.62/gallon ($0.16/liter) Wood Chips @ $55/ton = Propane @ $0.68/gallon ($0.18/liter) Wood Chips @ $60/ton = Propane @ $0.74/gallon ($0.20/liter) Wood Chips @ $65/ton = Propane @ $0.80/gallon ($0.21/liter)

Wood Chip vs. Oil Cost Wood Chips @ $45/ton = Oil @ $0.76/gallon ($0.20/liter) Wood Chips @ $50/ton = Oil @ $0.86/gallon ($0.23/liter) Wood Chips @ $55/ton = Oil @ $0.94/gallon ($0.25/liter) Wood Chips @ $60/ton = Oil @ $1.03/gallon ($0.27/liter) Wood Chips @ $65/ton = Oil @ $1.10/gallon ($0.29/liter) Current Fuel Oil Cost in Canada

Case Study Norwich University Norwich University is located in Northfield Vermont and was founded in 1819. The biomass plant was completed in October 2013

Case Study Norwich University Two 400 HP, 150 PSI steam boilers have a total output of 26 MMBTU/ hr (7.6MW) at 125 psi in winter and 50 psi during summer months. They generate up to 230 kw with a back pressure steam turbine. The biomass system displaces 700,000 800,000 gallons of fuel oil/yr by burning 10-13,000 tons of green wood chips which are purchased from local suppliers within a 100 mile radius. Overall project cost of $6 million includes a new biomass plant, boiler equipment and new underground piping to two new dorms. Savings of $2.2 million in first 20 months of operacon! Uses best available technology (electrosta5c precipitator) to reduce par5culate emissions to 0.028 lb/ MMBtu, less than half of U.S. EPA requirement for this size boiler system.

Case Study Hotchkiss School The Hotchkiss School is located in Lakeville, Connec5cut and serves 635 students in grades 9-12. The biomass plant was completed in July 2012 and has shown cost savings of $600,000 per year.

Case Study Hotchkiss School

Case Study Hotchkiss School Two Messersmith 300 HP, 10 MMBTU/hr. 150 psi steam boilers generate a combined 20 million BTU/hr (6MW) burning wood chips acquired from sustainably harvested local forests. This Central Hea5ng Facility heats all 1.2 million square feet of the 8 5 buildings that comprise the campus of the Hotchkiss School. Biomass hea5ng has reduced the Hotchkiss carbon footprint by more than 6 million pounds of CO 2 /year. Sulfur Dioxide emissions were c ut by over 90%. Waste ash from combus5on is collected for use as fer5lizer for the school s gardens to increase the soil ph, and an electrosta5c precipitator removes 98 % of par5culate ma]er from emissions.

Case Study Androscoggin Valley Hospital Androscoggin Valley Hospital is located in Berlin, New Hampshire. The new biomass plant was completed in March 2014 and has shown cost savings of $350,000 per year.

Case Study Androscoggin Valley Hospital One Messersmith 250 BHP 8.5 MMBTU/hr. (2.5MW) 150 psi steam boiler opera5ng at 80 psi The hospital burned 135,000 gallons of No. 2 fuel oil annually before the biomass boiler installa5on. AVH replaced their oil with 2300 tons of locally sourced wood chips. The biomass plant saves the hospital ~$350,000 annually in hea5ng costs. The biomass plant will pay for itself in eight years. The processed steam gets used to heat the hospital facility as well as sterilize equipment in the opera5ng rooms and in the kitchen.

Case Study Na5onal Life Insurance Group Na5onal Life Insurance headquarters is a 500,000 sq. [. facility located in Montpelier, VT. The new biomass plant was completed in December 2010 and yields an average cost savings of $400,000 per year.

Case Study Na5onal Life Insurance Group Two Messersmith boilers with combined 350 BHP or 12 MMBTU/hr (3.5 MW). Low pressure steam boilers opera5ng at 12 psi The biomass system displaces 210,000 gallons of No.4 fuel oil / year. The biomass facility meets 95% of the building s heat demand while reducing the company s carbon footprint by 45%. Cost for the new facility was ~$2 Million with a payback of 5 years. An ESP reduces par5cle emissions by 98%.

Case Study New Hampshire State Office The New Hampshire State Office Facility is located in Concord, NH. The new biomass plant was completed in April 2016.

Case Study New Hampshire State Office This 150 psi steam boiler system produces 8.3 MMBTU/hr (2.5 MW). The biomass boiler consumes 2,100 lbs per hour of wood chips at maximum output and displaces 422,000 therms of natural gas annually. The State of New Hampshire will see an 80% reduc5on of fossil fuel usage at this facility with their new biomass boiler system. The chips burned in this system are coming from local vendors and being trucked by local drivers. This enables New Hampshire to invest their hea5ng dollars back into their local community.

Wood Chip Project Challenges in Public Ins5tu5ons Successful projects require a Local Champion. Lack of educa5on on the benefits of wood based fuels Long project development 5me for public ins5tu5ons The footprint needed for a biomass boiler facility is larger than that of a typical boiler room due to the fuel storag e area required. Logis5cs with fuel truck delivery 5mes needs to be coordinated around high traffic 5mes in parking areas.
