Biomass-to-Energy Boilers Customized Engineered Solutions Since 1976, Jansen Combustion and Boiler Technologies, Inc. (JANSEN) has provided customized engineered solutions to owners/ operators of boilers in the Forest Products and Waste-to-Energy Industries. Our mission is to improve the operating performance (fuel burning capacity and economy, efficiency, and emissions perfor-mance) of existing boilers The Schuyler plant started producing in 2008. that burn difficult fuels such as biomass, chemical spent equipped a Conveying Industries EC-liquors, municipal with solid waste (MSW), r efuse derived fuel Fuji (RDF) and r tir e derived fuel (TDF). 201 Ace obot stacker and a Wulftec Biomass-to-Energy Boilers Customized Engineered Solutions Since 1976, Jansen Combustion and Boiler Technologies, Inc. (JANSEN) has provided customized engineered solutions to owners/ operators of boilers in the Forest Products and Waste-to-Energy Industries. Our mission is to improve the operating performance (fuel burning capacity and economy, efficiency, and emissions perfor-mance) of existing boilers that burn difficult fuels such as biomass, chemical spent liquors, municipal solid waste (MSW), refuse derived fuel (RDF) and tire derived fuel (TDF). JANSEN has conducted engineering perfor-mance evaluations of over 300 boilers, world-wide, and has provided combustion system and/or superheater upgrades of over 80 biomass, chemi-cal recovery, MSW, and RDF boilers.

Much of the physical fa-cilities and equipment were sold, scrapped, or torn down. About the only thing left is the forming line and 200,000 square feet of buildings that are used as warehouse space. The new plant has several innovative design features, especially in safety and cost efficiency. The mill floor is a com-pact layout housing an M-E-C triple-pass dryer, two 500-hp Bliss hammermills, four Andritz pellet mills, an automated Hamer bagger, and a Wulftec shrink-wrap turn-table. Only the plastic covering is manually positioned onto the stacked pallet before it enters the Wulftec system. Key design improvements include a Wellons furnace with an oversized dryer that allows a reduced drying temperature of just 315°C. This is considerably lower than in conventional drum dryers, which helps reduce volatile organic compound emissions. The in-house fabricated storage silos have fabric tops that allow the cloth to disintegrate in the event of an explosion and prevent structural damage to the stor-age cylinder. A Kice baghouse and six cus-tomized Fisher Klosterman cyclones help the plant meet New York’s stringent emis-sions permit requirements. NEWP worked with equipment ven-dors to incorporate a centralized process control system that manages every motor and control throughout the plant. Standard machine controls were either eliminated or bypassed so that one system controls the entire plant and there are no commu-nication problems from one machine to the next. “We did this basically for mill A synopsis of our broad range of services: > Full service engineering design for steam, power, and combustion systems > Biomass, MSW, RDF, TDF, fossil fuel, and chemical recovery boiler performance evaluations > Effective overfire air (OFA) delivery system upgrades on biomass and other waste-fueled boilers > Replacement or upgraded superheater design and supply > Boiler circulation analyses > Computational Fluid Dynamics (CFD) modeling > Feasibility studies and cost/benefits analyses > Emissions reduction (CO, NO x , PM, SO 2 , TRS, VOC) > Operations support and training CO 2 Find out how we can help you: (425) 952-2825 www.jansenboiler.com (425) 952-2825
