The plasma-chemical hybrid process (PCHP) has been effectively employed for the simultaneous removal of NO_x and SO_x in combustion gases. In this study, a PCHP-based semi-dry-type desulfurization reactor was developed for high-temperature exhaust gas from a glass melting furnace with a 10-MW-class thermal input. The NO in the exhaust gas is oxidized to NO₂ by ozone generated from scale-up dielectric barrier discharge-based plasma ozonizers with a total input power of 77 kW and total ozone generation of 10 kg/h. SO₂ reacts with NaOH solution in the semi-dry reactor to produce Na₂SO₃, which further reacts with NO₂ to reduce NO_x to N₂. The produced Na₂SO₄ is in the form of dry particles and can be collected and reused in glass manufacturing. The exhaust gas at the outlet of the semi-dry reactor is maintained between 200 and 250 °C to protect the dry-type electrostatic precipitator. A localized cooling area is created by spraying cooling water, which is necessary to prevent the thermal decomposition of ozone and to spray an efficient aqueous solution for achieving dry conditions at the reactor outlet. Simultaneous desulfurization and denitrification were tested at low glass-production rates by injecting adequate flow rates of ozone for NO removal. Optimal removal efficiencies of 45 and 39% were obtained for NO and NO_x, respectively. More than 90% of the byproducts were recovered in the form of Na₂SO₄. The designed facility with the semi-dry-type PCHP was confirmed to be highly effective and promising for exhaust gas treatment in glass manufacturing.

等离子体化学混合工艺 (PCHP) 已被有效地用于同时去除燃烧气体中的 NO _x和 SO _x。在这项研究中，开发了一种基于 PCHP 的半干式脱硫反应器，用于处理热输入为 10 MW 级的玻璃熔窑的高温废气。排气气体中的NO被氧化成NO ₂通过与77千瓦的总输入功率和10公斤/小时的总臭氧产生从按比例放大介质阻挡基于放电等离子体臭氧发生器产生的臭氧。SO ₂在半干反应器中与NaOH溶液反应生成Na ₂ SO ₃，Na ₂ SO ₃进一步与NO ₂反应将NO _x还原为N₂ . 产生的 Na ₂ SO ₄以干燥颗粒的形式存在，可被收集并重新用于玻璃制造。半干式反应器出口的废气保持在200～250℃之间，以保护干式电除尘器。通过喷淋冷却水形成局部冷却区，这对于防止臭氧的热分解和喷淋有效的水溶液以在反应器出口处实现干燥条件是必要的。通过注入足够流速的臭氧以去除 NO，在低玻璃生产率下测试了同时脱硫和脱硝。NO 和 NO _{x 的}最佳去除效率分别为 45% 和 39%， 分别。超过 90% 的副产物以 Na ₂ SO ₄的形式回收。设计的半干式 PCHP 设备被证实对玻璃制造中的废气处理非常有效和有前景。
