VIESSMANN MANUFACTURING COMPANy INC. HURST BOILER ANd WELdING CO., INC. www.hurstboiler.com www.viessmann.ca Clean burning and efficient, Viessmann biomass boilers offer state-of-the art safety equipment and fully automatic operation in an efficient, environmentally friendly so-lution suited to a broad range of commer-cial and industrial applications. Viessmann Pyrot (512 to 1843 MBH) and Pyrotec (1330 to 4268 MBH) wood-fired boilers feature advanced combustion technology to match the quality of modern gas com-bustion while generating comparable CO and NOX emissions. When outfitted with Viessmann digital modulating output con-trols, these boilers achieve an excellent ef-ficiency up to 85%, making them ideal for integration with renewable energy systems that may also incorporate Viessmann gas/ oil-fired boilers (for peak loads/biomass boiler backup), solar systems and DHW storage tanks. All Viessmann wood-fired boilers are built to ASME, Section IV re-quirements and have been tested to CSA/ UL Safety Standards. Hurst Boiler Co. specializes in the manu-facturing of modular biomass boiler sys-tems with outputs ranging from 28 kW to 52 MW thermal. Boiler vessel designs (CRN registered) include firebox, vertical tubeless, hybrid water/ fire-tube, and wa-ter-tube. Operating pressures range from 15 to 900 psi, with steam superheat avail-able. Modular biomass thermal to electric cogeneration systems are offered in 250 kWe, 500 kWe, 1 MWe, 3 MWe and 5 MWe packages. Hurst manufactures seven differ-ent types of biomass stoker/gasifiers, which have used almost 2,000 different types of biomass fuels over the last 40 years. Hurst has grown with more than 350 employees, becoming an experienced, reliable, and stable biomass thermal system supplier. PRATT & WHITNEy is committed to providing clean, efficient and reliable power within the renewable energy market. Pratt & Whitney PWPS’ Organic Rankine Cycle (ORC) power plants provide heat to electric power generation for biomass, geothermal, heat recovery, and concentrated solar appli-cations. Our biomass ORC systems for cogeneration allow simple and highly ef-ficient production generation of electric power and heat with sizes ranging from 1 kW to 10 MW. PWPS’ ORC prod-ucts include benefits such as 24/7/365 remote control and monitoring, 195°F to 660°F (90°C to 350°C) temperature range, and standardized components and assembly processes. WELLONS www.wellonsfei.ca/www.wellons.ca www.pw.utc.com Pratt & Whitney Power Systems (PWPS), a division of United Technologies (UTC), Wellons, Wellons Canada and Wellons FEI are all part of the Wellons group of companies, supplying the North Ameri-can market with wood fired energy sys-tems and dry kilns for the past 40 years. Wellons FEI supplies energy systems us-ing a stepped grate technology with a fully automatic ash extraction system. Capacity of the systems we build is appropriately sized for medium-and large-sized district heating systems such as hospitals or a uni-versity campus. Applications include process kRANN ENGINEERING LTd. www.krann.ca Krann offers biomass boiler systems in 1 to 20 MW range for both hot water and steam, pow-ered by Krann gasification furnaces. Typically, no filters are needed for flue gases handling because of the low emission levels. These sys-tems can be used to generate electrical power through either the steam turbine or the ORC module. Fuels used include hog fuel, shavings and recycled wood waste, with moisture content up to 60%. Applications for the systems include sawmills, greenhouses, drying facilities, municipal buildings and hospitals. Sys-tems are turnkey, fully automated from fuel storage to exhaust.
