三次风 meaning in English
tertiary air
Examples
- Hot waste gas from grate cooler is divided into four parts : part of it is sent to kiln as secondary air , part of it is sent to decomposition furnace as burning air by tertiary duct , and the rest is drained to the atmosphere after purified by electric dust collector at kiln head
出篦冷机高温废气一部分作为窑用二次空气入窑；一部分由三次风管送到分解炉作为燃烧空气；剩余废气经窑头电收尘器净化处理后排入大气。 - These produels are produced by the techniques same with chemical bonded non - sintered bricks with semi - silica raw materials , they have high strength , good heat insulating and alkali resistant properties , they are mainly applied to the zones of large - sized cement rotary kilns which are croded badly by alkali , for example , the input zone , preheater , three - windtunnel , and decomposing zone
本产品采用半硅质原料，以化学结合不烧工艺生产而成，它具有强度高、隔热效果好、抗碱侵蚀能力强的特性，主要用于大型水泥回转窑筒入料区段、预热器、三次风管和分解带等碱侵蚀严重的部位。 - Reburning technology is a valid method . this paper focuses on nox - emission problem of traditional units with hot air transferring pulverized coal . the main technical route of this paper is to use the pulverized coal contained within tertiary air to reduce the nox emission as the reburning fuel
本文主要是针对传统的缺少有效降低no _ x方法的热风送粉机组进行研究，通过对制粉系统和燃烧器的改造与调整，利用三次风中的含粉作为再燃燃料送入炉膛，实施再燃烧以降低no _ x的排放。 - This paper consists of the following parts : firstly , the physical properties ( particle size distribution , specific area , porosity ratio and pore volume ) and pyrolysis characteristics have been studied in experiments with four kinds of coals . according to experimental results , the advantages of combustion characteristics of micro - pulverized caols are analysed on the theory . secondly , the reconstructing plan is designed in details for a conventional system of the hot air transferring pulverized coal to reduce nox emission
本文主要包括以下内容：首先，通过基础的实验分别对四种具有代表性煤种一、三次风所含煤粉的物理特性(粒径分布、孔隙率、孔容积和比表面积)和热解特性进行研究，从理论上分析煤粉细化后，较细颗粒(即三次风含粉)在燃烧特性上的优越性，为三次风含粉用于再燃燃烧打下基础。
