Multi-atmosphere furnace | Supports firing and exhaust gas treatment accompanied by harmful gas generation.
Addressing the hard-to-see exhaust gas risks on a small scale through scale-up solutions in furnace, exhaust, and emission control design.
Our company offers a "Multi-Atmosphere Furnace" designed to handle the firing process that generates harmful gases such as NH3, CO, and NOx. During the firing of raw materials containing organic substances, resin-based materials, catalyst carriers, and battery materials, gases such as NH3, CO, NOx, HCN, and hydrocarbon gases may be emitted during heating and holding. Gases that were not an issue in small tubular furnaces or small-scale tests can become significant challenges in terms of exhaust concentration, emission volume, corrosiveness, and safety measures as the number of tray layers and processing volume increase. Our Multi-Atmosphere Furnace can design the entire firing process, including vacuum replacement, atmosphere control, heating, exhaust, and coordination with emission treatment equipment. 【Features】 ■ Furnace design considering the generation of gases such as NH3, CO, and NOx ■ Gas replacement in the furnace before and after processing through vacuum replacement ■ Compatibility with various atmospheres such as N2, Ar, Air, and NH3 ■ Consideration of emission treatment methods such as scrubbers, catalytic oxidation, and thermal oxidation ■ Support for scale-up considerations anticipating increased tray layers and processing volume *For more details, please download the materials or contact us.

Applications/Examples of results
【Applicable Fields】 ■ Material processing that generates NH3, CO, NOx, HCN, etc. ■ Atmosphere sintering of catalysts, ceramics, battery materials, and powder materials ■ Dehydration, decomposition, carbonization, and nitriding condition studies for organic-containing materials ■ Scale-up considerations from small tests to multi-stage tray and mass production furnaces ■ Design of sintering processes including exhaust and emission control 【For Such Challenges】 ■ Gas generation increases dramatically when scaling up ■ NH3 and CO, which were not problematic in small furnaces, become significant under mass production conditions ■ Concerns about exhaust line blockages, condensation, corrosion, and backflow ■ Insufficient gas resistance and corrosion resistance of heating furnaces, crucibles, and sealing materials ■ Want to consider not only the furnace but also scrubbers and catalytic oxidation Even at a stage where raw materials, processing temperatures, processing amounts, and generated gases are uncertain, you can consult with us regarding exhaust and emission control.
