Jansen Combustion and Boiler Technologies

Jansen Combustion and Boiler Technologies is looking forward to seeing everyone at the PACWEST Conference next month! 😊

Our blog today tackles the age old question faced by every boiler operator, "What is the right amount of air flow to optimize combustion in my boiler?" And then, what about NOx? Today we attemp to shed light on the intrinsically linked components of combustion: CO and NOx, and how understanding their behavior is the key in combustion optimization. https://lnkd.in/ghTsakxh #combustion #CO #NOx #efficiency

In this blog post, we discuss superheaters which are boiler components that play an essential role in power generation. A superheater tube is unlike any other tube in a boiler. Unlike furnace water walls and generating bank/evaporator tubes where the inside medium always remains at the drum saturation temperature, steam temperatures in superheater tube can vary from tube to tube with the hottest tubes corresponding to the steam side outlet of the superheater. Therefore, the operation of superheaters becomes an intricate union of fluid flow and heat transfer which requires the superheater designer to track and account for the steam flow, flue gas flow, and heat transfer over every single superheater tube starting from the inlet tube to the outlet tube. Not paying attention to the varying degrees of heat transfer can lead to incorrect selection of surface area, tube thickness, and materials selection which can sometimes lead to catastrophic consequences. Today, we discuss the Do’s and Don’ts of Superheater design https://lnkd.in/gC-653zE Our team at Jansen has a proud history of designing and supplying superheaters that are effective at achieving performance goals while incorporating robust designs that are meant to last.

Our past blog has discussed options to restore Sweetwater Condenser capacity even when feedwater temperatures are increased. But sometimes, feedwater temperatures entering the steam drum are far too close to the drum saturation temperature thus introducing the potential for deficient circulation, tube overheating, and failures. This second part of our two part blog series investigates this scenario and offers potential solutions. We hope that you enjoy the read. https://lnkd.in/gKNGxKrJ Contact us to discuss your feedwater system issues. We have the expertise to provide you with robust and creative solutions. #steamboiler #feedwater #circulation #overheating #failures

Jansen Combustion and Boiler Technologies (Jansen) has acquired the Redmond, Washington based Lundberg LLC (Lundberg), formerly a division of LDX Solutions. Founded in 1976, Lundberg specializes in the design and supply of custom solutions including engineering, systems and equipment for the process industries to meet each client's unique needs. The acquisition includes Lundberg offices in both Redmond, WA and Bilbao, Spain. The acquisition expands Jansen’s product offerings beyond its pulp mill recovery boiler and biomass boiler technologies to include a variety of pulp mill technologies, including environmental, energy efficiency, evaporation and chemical processing systems. The combined company features recognized pulp mill industry experts in each of these areas to provide optimal process and equipment solutions. Jansen President Doug Giarde says: “We are very pleased to welcome the Lundberg teams in Redmond and Bilbao into the Jansen family. Their expertise in pulp mill systems will combine with Jansen’s boiler expertise to form a full service pulp mill/power & recovery engineering and equipment supplier for the pulping industry.”

In our previous Jansen Combustion and Boiler Technologies blogs, we have discussed areas of boiler performance related to combustion efficiency and effectiveness of heat transfer. Our latest blog is a two-part discussion of a critical aspect for maximizing steam generation related to the feedwater temperature entering the drum. Although hotter feedwater temperatures are desirable, sometimes too much of a good thing can lead to unintended consequences like boiler tube failure or superheater performance issues. https://lnkd.in/gy5up2Ci Stay tuned for Part II, which is coming next week! #steamgeneration #boiler #failures

The workshop in Charlotte is going to be a great event and we hope that you will consider attending.

In our latest blog post, Joe Klover discusses the various factors that need to be considered when evaluating the potential for power boilers to incinerate Concentrated Non-condensable Gases (CNCGs) and Stripper-off-Gases (SOGs) which are typically generated in pulp and paper mills. Existing power boilers can serve as an ideal location to incinerate these gases provided that the furnace size and combustion system design is adequate to satisfy the destruction/oxidization of the total reduced sulfur (TRS) and volatile organic compounds (VOC) contained in these streams. In addition, a holistic evaluation of the boiler system is necessary to ensure that corrosion will not become elevated due to CNCG and SOG incineration. The blog post also provides an example of a recent Jansen evaluation of a paper mill power boiler in the US Midwest where a detailed analysis confirmed the adequacy of a boiler furnace to incinerate CNCG and SOG and identified the main boiler modifications necessary to safely incinerate these stream and prevent corrosion. We are now working with our client to design the necessary equipment to incinerate CNCG and SOG and control corrosion. We hope that you enjoy the read. https://lnkd.in/gqqBRNx3   Contact Jansen to discuss how we can help you answer your “burning” questions regarding CNCG and SOG 🔥   #boilers #CNCG #SOG #SO2 #corrosion #incineration

Our newest blog post discusses how furnace geometry and other design deficiencies that lead to ineffective combustion can be investigated and often addressed using sophisticated tools like CFD modeling. All of Jansen’s CFD modeling is done in-house using custom developed programs to simulate combustion processes for solid, liquid, and gaseous fuels. Combustion is a complex amalgam of fluid dynamics, chemistry, and thermodynamics. CFD modeling has emerged as a powerful tool in helping to demystify the process and illuminate the opportunities. https://lnkd.in/gbNQY_nJ #cfd #combustion #furnace #combustionoptimization #efficiency #OFA #simulation
