FINK AND KÖB TURN WASTE WOOD INTO DOLLARS
Fink is the authorized sales agent for KÖB, which manufactures the Low-Particle Firing Pyrot Rotary Combustion Chamber Boiler and the Pyrtec Moving Grate Combustion Boiler. These fully automatic chip and pellet boilers are available in sizes from 80 kW to 2500 kW (270,000 to 8.5 million BTU).
The Pyrtec takes wood fuels ranging from dry pellets to moist forest wood chips, while the Pyrot uses dry woodchips, wood pellets or wood byproducts. The equipment meets commercial, institutional and/or industrial heating requirements, and the company’s specialty is installing large heating systems. Fink is experienced in biomass-based systems for district heating grids, woodchip and pellet systems for municipal buildings and local heating networks.
EFFICIENT KMW ENERGY SYSTEMS
KMW Energy Inc. specializes in the engineering and supply of thermal and combined thermal and power systems. Each KMW Energy system is custom designed and engineered to suit the requirements of each application, with thermal energy outputs ranging from 150 boiler hp to 4000 hp and power generation from 1 MW to more than 25 MW. Successful combustion/gasification tests have been made using KMW Energy test units installed at Ortech International in Mississauga, Ont., and CANMETEnergy Technology Centre, Ottawa, on such materials as refuse-derived fuel (RDF) from municipal waste, scrap tires, construction debris, waste paper, peat, chicken litter, corn stover, rice husks and mill sludge.

JANSEN ENGINEERS AND UPGRADES
Jansen Combustion and Boiler Technologies, Inc. provides engineering evaluations, CFD modelling, boiler retrofit/modifications, engineering/design and design. The company provides engineering and equipment to upgrade and modify existing biomass and waste-fuelled boilers, including stoker grate units and fluidized bed boilers. Jansen has provided upgrades on biomass and combination fuelled fossil/biomass boilers ranging in size from 60,000 lb/hr steaming rate up to 800,000 lb/hr. Generally its work has been in the industrial and independent power-producing industry. Its engineering includes detailed evaluation/characterization of the boiler, design of cost-effective combustion and heat transfer solutions, and detailed design and equipment supply. Jansen’s upgrades provide increased steam production from biomass and waste fuels, improved air emissions, improved boiler efficiency, and reduction/elimination of fossil fuel co-firing. Engineering analysis includes in-house computational fluid dynamic (CFD) modelling of each individual boiler, steam/water circulation analyses that include ultrasonic flow monitoring of critical boiler circuits, design engineering, equipment supply and project management.

HIGH EFFICIENCY, LOW EMISSIONS TEAFORD TRADEMARKS
High efficiency, low environmental emissions, and generous sizing are the trademarks of Teaford Company biomass-fired boilers. These units are designed with multi-stage burners, and can be provided in the following sizes: field-erected boilers with up to 300,000 PPH steam output and superheated up to 1200 PSIG/1200 F, and package boilers with up to 70,000 PPH steam output and superheated up to 1200 PSIG/1200 F. Teaford’s field-erected and package boilers feature saturated or superheated steam; high- and low-pressure designs; tangent tube, tube and tile, and membrane wall designs; wet and dry fuel systems; wet fuel up to 55% moisture content wet basis; reciprocating grate; auxiliary gas or oil burners; air preheaters and economizers; pollution control including ESPs; SCR and SNCR NOx reduction systems; and high combustion efficiency systems. Package boilers feature compact low-cost firetube designs; watertube designs for high pressure; combination watertube and firetube designs; high- and low-pressure designs; and complete turnkey plants. Teaford’s custom design of boilers can include many different options to meet individual site requirements while maintaining high efficiency and low cost parameters. Most Teaford systems are for industrial operations that use steam in dry kilns, heat exchangers, dryers, for conditioning of materials and electrical generation/cogeneration. Some electrical generation users are power companies trying to get renewable energy as part of their overall electrical production, while others are single companies (universities, mills, etc.) powered by cogen systems. www.teafordco.com, www.teafordcanada.com
WELLONS ON ITS WAY WITH TWO BOILER OFFERINGS
|Wellons’ Combuster Cell applications include sawmill and board plant energy systems, biomass fired electrical generation and CHP systems and direct-fired systems. The Stepped Grate Furnace suits the medium- and large-sized district heating systems used in hospitals and university campuses.
With the Combustor Cell you can choose either an overfeed green fuel configuration with automatic ash removal or an underfeed dry fuel configuration with manual ash removal. Modular design of the unit in two- to six-cell configurations provides gross combustion input ranging from 4 to 140 MW. With a capacity of 3 to 73 MW for steam boilers, and 6 to 30 MW for thermal oil heaters. Suitable fuel types include bark, sawdust, wood chips, wood pellets and forest residuals. Applications include sawmill and board plant energy systems; biomass-fired electrical generation and CHP systems; and direct-fired systems to provide hot gases to dryers for pellet plants, MDF or OSB facilities.
