Energy‐saving glass‐melting‐furnace with semi‐dry plasma‐chemical hybrid process

Abstract

A low‐cost plasma‐chemical hybrid process (PCHP) is proposed for simultaneous NOx and SOx treatment. PCHP can be integrated into existing desulfurization reactors by combining plasma oxidation and chemical reduction. PCHP is applied to glass melting furnace emissions with limited denitration technology, achieving higher removal efficiencies of NO, NOx, and SO2 (43%, 38%, and 28%, respectively) by optimizing reductant spray and installation angles. PCHP also improves fuel consumption, with a 0.04 increase in air ratio reducing energy consumption by 3.6 kL/day (equivalent to 6.6 t(CO2)/day reduction). In addition, PCHP allows for the collection and reuse of treated SO2 as sodium sulfate particles, making it a suitable aftertreatment technology for glass manufacturing exhaust.

Special issue: Renewable energies

“…[17] CO 2 separation from the dry methane reforming reactor effluent is generally energy intensive but necessary to increase the product yield as high CO 2 :CH 4 ratios are necessary; the paper provides insightful information from the application perspective. Additionally, alloyed catalyst preparation by glow discharge, [18] industrialscale exhaust gas clearing by plasma ozonizer, [19] and N 2 fixation by the warm plasma combined with catalysts [20] are presented.…”
