42 Best-in-Class Community-Scale Biomass Systems Case Study Series Biomass Energy Resource Center (BERC) Founded in 2001, BERC is a national not-for-profit organization working to promote responsible use of biomass for energy. BERC s mission is to achieve a healthier environment, strengthen local economies, and increase energy security across the United States by developing sustainable biomass systems at the community scale. Introduction BERC partners include communities, colleges and universities, local state and federal governments, businesses, utilities, schools, institutions, other conservation and energy nonprofits, energy offices, and federal organizations.

43 Best-in-Class Community-Scale Biomass Systems Case Study Series Presentation Overview Fuel availability, quality, and delivery Integration with other renewables Boiler configuration Thermal storage Introduction Emissions controls Containerized units Boiler design

44 Best-in-Class Community-Scale Biomass Systems Case Study Series Regional Pellet Production and Availability Fuel Supply

45 Best-in-Class Community-Scale Biomass Systems Case Study Series Traditional Pellet Delivery Fuel Supply

46 Best-in-Class Community-Scale Biomass Systems Case Study Series Bulk Delivery Advancements Use of pneumatic systems Reduced pellet breakage during delivery!!! Dust control systems for indoor storage bins are essential Fuel Supply On-board scales = accurate measure of every delivery Allows indoor storage for better aesthetics

47 Best-in-Class Community-Scale Biomass Systems Case Study Series Energy Integration Solar Hot Water Integration Roof top mounted solar hot water panels Typically covers woodchip storage roof Feeds directly in buffer tank storage and integrates with boiler fed hot water

48 Best-in-Class Community-Scale Biomass Systems Case Study Series Buffer/Accumulator Tanks Large hot water storage Range widely in size (1,000 10,000 gallons per MMBtu/hr of boiler capacity) Vertical alignment and stratified zone management Allows small boiler sizing and reduces boiler run time in idle/pilot mode Applicable from residential to large district heating plants Increasingly packaged with boilers by vendors Thermal Storage

49 Best-in-Class Community-Scale Biomass Systems Case Study Series Boiler Configuration Coupled Boilers Typically two parallel boilers (generally 2 nd boiler = +/-½ capacity of 1 st ) Better load management in shoulder months and ability to run boilers at full capacity Results in better efficiency and cleaner emissions Apartment building in Wesenufer, Austria National Life, Montpelier, Vermont District heating plant in Kirchham, Austria Crotched Mountain Rehab Center, Greenfield, New Hampshire

50 Best-in-Class Community-Scale Biomass Systems Case Study Series Emissions Controls Electro-Static Precipitators Previously only cost-effective at very large scale Now cost-effective in the >3 MMBtu size range Control efficiency of 99% for particulates Far better the control efficiencies than cyclones Lower O&M costs than bag houses Wide spread use in Austria but catching on here in US for woodchip boilers

51 Best-in-Class Community-Scale Biomass Systems Case Study Series Emissions Controls Condensing Units Capture and heat recovery of water vapor in stack gases Boosts overall thermal efficiency by +/-10% Dramatically lowers fine particulate and VOC emissions Effective for green wood fuel What to do with the water afterwards? District heating plant in Eugendorf, Austria

52 Best-in-Class Community-Scale Biomass Systems Case Study Series Containerized Units Plug and play design Integrated fuel storage and boiler housing Not just for pellets chips too Considerably lower overall capital costs Can be architecturally blended

53 Best-in-Class Community-Scale Biomass Systems Case Study Series Boiler Design Boiler Design Features Vertical boiler tubes with continual mechanical cleaning (gravity based) in small boilers Water lined boiler walls (less boiler jacket loss) Longer refractory lined gas routing before heat exchange (longer gas residence time) Preheated primary and secondary air

54 Best-in-Class Community-Scale Biomass Systems Case Study Series What does it all mean? Higher quality fuel = better system performance, lower O&M costs, and lower emissions Buffer/accumulator tanks = more constant boiler loads, lower peak loads allowing smaller boiler sizing Solar thermal integration = lower heat loads allowing smaller boiler sizing and less wood fuel consumption Coupled boilers = better load management and higher efficiencies ESPs and Condensing Units = lower fine particulates and happy neighbors and air quality regulators Containerized systems = lower capital costs and faster paybacks Innovative boiler designs = high thermal efficiencies, cleaner emissions and less maintenance
