工業鍋爐脫硝設備包括尿素溶液制備系統（攪拌罐、轉運泵、儲存罐）、尿素溶液輸送泵站模塊（立式多級離心變頻泵1用1備、背壓閥、返回閥、過濾器、止回閥、壓力表、底座、電控箱）、計量模塊（電磁流量計、止回閥、壓力變送器、旁路閥）、除鹽水輸送泵站模塊（立式多級離心變頻泵1用1備、背壓閥、返回閥、過濾器、止回閥、壓力表、底座、電控箱）、計量模塊（金屬管浮子流量計、止回閥、壓力變送器、旁路閥）分配模塊（管道式不鏽鋼轉子流量計、壓力表、針型調節閥、壓縮空氣調節閥、分配器等）、脫硝噴槍（噴嘴、槍杆、保護套管、混合器、快速接頭、快拆卡子等）、PLC電控系統、管道系統（尿素溶液管道、壓縮空氣管道）。

作爲還原劑的尿素溶液，預先在攪拌罐調配濃度爲20％尿素溶液，經尿素溶液輸送泵輸送至尿素溶液儲罐，經泵站模塊、計量模塊輸送至分配模塊，然後再經過分配裝置的分配至每個噴槍，經噴槍噴入爐膛，進行脫硝反應。SNCR系統將尿素溶液噴入爐膛中並使其均勻分布。SNCR系統是一個爐內的燃燒後脫硝反應，尿素溶液在爐膛內相應溫度窗口區域的精細分布程度是該系統性能的重要影響因素。

She closed the door of the room softly and gave a call. It was late at night, the exchange was quiet, and the answer came swiftly. Considered as means for transmitting power, the contrast as to advantages and disadvantages lies especially between belts and gearing instead of between belts and shafts. It is true in extreme cases, such as that cited at Crewe, or in conveying water-power from inaccessible places, through long distances, the comparison lies between belts and shafts; but in ordinary practice, especially for first movers, the problem as to mechanism for conveying power lies between belts and gear wheels. If experience in the use of belts was thorough, as it is in the case of gearing, and if the quality of belts did not form so important a part in the estimates, there would be but little difficulty in determining where belts should be employed and where gearing would be preferable. Belts are continually taking the place of gearing even in cases where, until quite recently, their use has been considered impracticable; one of the largest rolling mills in Pittsburg, Pennsylvania, except a single pair of spur wheels as the last movers at each train of rolls, is driven by belts throughout. I also met there a compatriot, who had got permission to go to The Netherlands, but declined to leave. She was Mrs. de Villers, née Borret. On August 27th I wrote about her to De Tijd:— Si snatched them apart, cuffed them, and lighted a bit of candle, which he kept for emergencies, to help them and the rest find their things. He improved the occasion to lecture them as to the way they should do in the future. That sounded more reasonable. Cadnan considered it for a minute. Wherever Marvor was hiding, it had to be somewhere in the jungle. And so, in order to find him, they had only to walk through it. "You can't keep me out here. It isn't my fault I'm late—and I'm not so very late, either." "On the great Moor of the lost "Yes, Edith Holgrave told me to give ten drops out of that little bottle," (pointing to the empty phial,) "and I—gave—but, oh! Master Calverley, I forgot—" "Calverley done all this!" said the baron in a tone of incredulity; but then, as the steward's persevering hostility to Holgrave flashed across his mind, it seemed to bring conviction.
