1 Heatin with Wood Heatin Systems Industrial Systems Refrieration Systems

2 Why Wood Heatin? Risin cost of fossil fuels and rowin concern for the environment have led to an increasin demand for renewable enery. Modern wood heatin is an eco-friendly and economical alternative (or addition) to conventional fossil fuel heatin systems. Did you know? A number of federal, state and utility incentive prorams are available throuhout North America. Visit for a list of U.S. state incentive prorams. In Canada, check the Natural Resources Canada website or contact your local Viessmann Sales Representative. Sustainable When harvested in conjunction with sustainable forestry, wood is a renewable and environmentally-responsible form of enery and an important part of sustainable resource manaement. CO 2 -neutral Burnin wood releases as much CO 2 as trees absorb in their lifetime. Heatin with wood is therefore CO 2 -neutral** and does not contribute to climate chane. Economical As a local enery source, wood is affordable and independent of wide price fluctuations. In times of volatile enery prices, wood remains stable and hihly competitive. Hih-tech and reliable Modern biomass systems are fully-automatic and equipped with hih-tech control and safety devices for reliable, efficient and safe operation. Local and independent Wood is a local staple and independent of wide price fluctuations. Wood is harvested with minimal enery input and contributes to the reional economy. **Wood is a "near carbon neutral" fuel to reflect that fact that a small amount of fossil fuel is used to harvest, process and transport the wood. Typically this is less than 1% of the total carbon content.

3 2/3 What You Need to Know What type of wood can I use? Viessmann wood heatin systems can use a variety of untreated, hih-quality wood fuels that vary in heatin value, required storae capacity and cost (see riht column). What fuel type you choose will larely depend on your storae capacity, system requirements and the availability of the fuel in your area. As the quality of the fuel impacts the efficiency and life expectancy of your system, it is best to choose a ood-quality, untreated wood fuel with a low water content. How economical is it? In a biomass system, the fuel cost is an estimated 50% of the total lifecycle cost. Choosin a hih-efficiency wood-fired boiler and hih-quality, cost-efficient wood fuel thus is key in optimizin the economy of your system. Compared to traditional fossil fuels, the averae cost per heat unit of wood fuel is sinificantly lower in most areas in North America. So while the investment cost of a biomass system may in many cases be hiher than a conventional heatin system, the fuel cost savins per unit of heat can offset the investment in a relatively short timeframe - makin your biomass system as economical or better than a fossil fuel heatin system. Plus, with a fuel source that is local and independent, your fuel cost is less volatile than with traditional fuels. Is it safe? Absolutely. Today s wood heatin systems are as safe and reliable as leadin as/oil heatin systems. Equipped with advanced safety and fire protection devices, and a diital control, the entire system is closely monitored and controlled - from the fuel feed riht to the heat transfer and ventin. Viessmann wood-fired boilers are built to ASME, Section IV requirements, are CRN reistered, and have been tested to CSA/UL Safety Standards (includin all safety controls). Is it clean-burnin? Yes! Modern wood heatin systems, when professionally operated and maintained, reach similar emission levels to leadin fossil fuel heatin systems. Better yet, wood heatin is CO 2 -neutral. Viessmann wood-fired boilers meet the strinent reulations of the European Clean Air Act. What applications can it be used for? Our wood heatin systems are ideally suited for commercial and industrial applications, such as schools, hospitals, community heatin systems, wood processin plants and more. They are desined to carry either the entire heatin load of your system or the baseload, when combined with an oil-/as-fired boiler for peak times. Our comprehensive product portfolio also allows you to expand your biomass installation into a fully interated system, complete with Viessmann solar, oil/as boiler and custom control technoloy (see pae 13).

6 VITOFLEX-UF State-of-the-art underfeed combustion wood-fired boiler, 1330 to 4268 MBH For wood fuels with max. water content of 50% Grate firin at its best The Vitoflex-UF boiler uses a burner trouh with an attached external rate and a movin annealin rate to achieve optimal combustion results. An infeed auer moves the wood fuel into the burner trouh where the fuel is pre-dried and asified under precisely controlled primary air (underfeed combustion). On the external and the movin annealin rate the fuel completely asifies. Precisely controlled secondary air is injected for full combustion and thermal enery is released into the boiler s triple-pass heat exchaner. Clean-burnin and efficient Equivalent in quality to modern as combustion, the advanced combustion process of the Vitoflex-UF keeps emissions of CO and NOx to levels comparable to those of modern fossil fuel heatin systems.

8 Fully Automatic and Low Maintenance A complete rane of system components from one source ensures reliable and smooth operation of the entire system. Automatic deashin system (optional) Clean combustion leaves behind wood minerals in the form of ashes. A movin rate extracts the ashes from the combustion chamber and transfers them into the ash container. Once cooled, the ash removal auer extracts the ashes into a lare external ash container. Flue as cyclone to meet low dust emission requirements. Pneumatic cleanin system (optional) A clean heat exchaner is key for the lonevity and efficiency of a boiler. The pneumatic cleanin system periodically removes ashes from the fire tube heat exchaner with micro blasts of compressed air, extendin the boiler s maintenance-free operation period sinificantly. Ash removal auer and external ash container Flue as recirculation system (standard for Vitoflex-RF, optional for Vitoflex-UF) Flue as contains little oxyen (6-8%). When mixed with primary air, it ensures complete asification of the fuel under air deficiency. This produces a low rate temperature that results in increased boiler efficiency, reduced particle emissions as well as reater rate lonevity. Flue as cyclone (optional) Minimizes dust emissions by filterin the flue ases throuh a multi-cyclone array. Comes fully insulated with an exhaust fan mounted on the side or top, and a 64 USG ash container. A 212 USG ash container is optional. (Only required for fuels with hih fine particle content, e.. waste wood from wood processin plants or woodchips with fine particle content of > 4%.) Pneumatic cleanin system Automatic firetube cleanin brush (service tool) Automated, pneumatic, vibratin cleanin brush cuts the cleanin time of boilers by 50%. When inserted from the front and activated, the brush runs throuh the individual tube and back, ently removin ash and dust deposits. Clean fire tubes ensure optimal heat transfer and increased efficiency. Flue as recirculation system

11 10/ 11 Safe and Reliable Operation Viessmann wood-fired boilers are built to meet the most strinent safety requirements. Hih-tech, stateof-the-art safety equipment ensures a safe and reliable operation of your system at all times. Backflash safeuard A water-filled meterin container attached to the infeed auer and controlled by an optical sensor. Prevents sparks from enterin the fuel storae area. The backflash safeuard is a CSA safety requirement. Burnback preventer A sensor located in the fuel infeed pipe detects any daner of burnback and quickly counteracts by increasin the feed to the boiler. Burnback safeuard A sprin-loaded horizontally-actin slide valve interrupts the fuel line in case of power failure or daner of burnback. If the fuel storae room is under neative pressure a rotary valve is used instead of the slide valve for the same function. The rotary valve prevents unwanted air leaks from reachin the combustion process. Safety heat exchaner A safety heat exchaner built into the boiler connects to city water and prevents the boiler from overheatin in case of a power outae. A non-electric, thermally activated valve is triered at a fixed boiler temperature and cools the boiler water via indirect heat transfer throuh the heat exchaner. Additional safety devices In addition to the safety equipment listed, Viessmann wood-fired boilers come with the standard safety devices required by the Safety Standards. Fixed temperature hih limit ASME pressure relief valve Low water cut-off (LWCO) Pressure and temperature aes The Vitoflex-RF and Vitoflex-UF boilers are built to ASME, Section IV requirements and 30 or 60 psi max. operatin pressure.
