What Jansen Combustion and Boiler Technologies does

Jansen Combustion and Boiler Technologies, Inc. is a privately held industrial engineering firm founded in 1976 and headquartered in Kirkland, Washington. The company specializes in combustion optimization and boiler performance engineering for industrial facilities burning hard-to-burn fuels, including biomass, black liquor, municipal solid waste (MSW), refuse-derived fuel (RDF), and tire-derived fuel (TDF). Its primary customers are kraft pulp and paper mills, energy-from-waste operators, and electric utilities, with engagement spanning engineering evaluations, combustion tuning, CFD modeling, and full turnkey boiler modifications. Jansen has evaluated over 250 biomass-fired boilers and more than 100 kraft recovery boilers worldwide, and holds ASME Section I 'S' and NBIC 'R' code stamps for pressure-part design and repairs.

The company's core technology stack combines three proprietary assets: (1) the patented High-energy Multi-range Combustion Air Nozzle (originally patented 1989), an overfire air nozzle designed to penetrate furnace gases with minimal pressure loss; (2) more than 30 years of in-house Computational Fluid Dynamics (CFD) modeling with field-calibrated proprietary algorithms; and (3) pioneering use of Ultrasonic Flow Metering (UFM) for non-invasive boiler circulation analysis. Service offerings span combustion tuning, performance evaluations, fluidized bed boiler services, superheater and economizer upgrades, erosion/corrosion analysis, regulatory compliance (Boiler MACT/GACT, CISWI, NOx), and full Engineering-Procurement-Construction (EPC) project delivery. Documented performance outcomes include 20-50% recovery boiler capacity gains, an average 33% CO emission reduction on biomass boilers post-OFA upgrade, and material reductions in stack gas temperatures and fuel firing rates.

The business model combines project-based professional engineering services with custom equipment design, fabrication, and one-time supply, plus managed EPC turnkey engagements. Pricing is quote-based and confidential, with multi-year project cadences. Go-to-market is direct enterprise field sales supported by regional representatives across North America (TeamPro in the Upper Midwest, an internal Southcentral US manager) and Brazil (ibase), augmented by twice-yearly Biomass Boiler Workshops and an extensive technical publication record at TAPPI, ICRC, BLRBAC, and NAWTEC conferences. The firm operates with 11-50 employees, and in March 2025 acquired Lundberg, LLC (formerly of LDX Solutions), extending its scope into pulp mill environmental, evaporation, and chemical processing systems and adding offices in Redmond, WA and Bilbao, Spain.
