Discussion on Over-temperature of Heating Surface in Blowpipe of Supercritical Unit Boiler 超临界锅炉吹管中受热面超温现象探讨
Tambun, 60, said he was crouching to shoot a squirrel with his blowpipe when he spied the big cat eyeing him for dinner. 60岁的谭布称,当时他正蹲着准备用吹箭筒射击一只松鼠,不料被一只老虎盯上,差点成了它的晚餐。
The hot air is always carried to the furnace by a powerful turboblower, through the hot blast main, bustle pipe, bootleg, blowpipe and tuyere. 热风由功率强大的鼓风机通过热风总管、环形风管、风口小弯管、直吹管和风口不断鼓人高炉。
The earth reclamation with marine muck filled through blowpipe has been the main technical method of ground development in Shenzhen region. 利用海相淤泥吹填造陆已成为深圳地区进行土地开发的重要技术手段。
N the blowpipe the isothermal two-phase flow fields behind an oxygen-coal lance for various structures were investigated. 研究热风管中不同结构的氧煤枪出口下游冷态两相流场。
Steam blowpipe for the HRSG of 400 MW-class co-axis gas-steam combined cycle unit 400MW级同轴燃气-蒸汽联合循环机组余热锅炉的蒸汽吹管
On the basis of the characteristics of BF Pulverized coal combustion, the combustion of pulverized coal in the blowpipe and tuyere is simulated step by step. The simulation result of the blowpipe is used as the input of the raceway calculation. 根据高炉喷吹煤粉燃烧特点,对直吹管和风口回旋区分段模拟,以直吹管模拟结果作为回旋区输入。
Mathematic Models for the Combustion of Pulverized Coal in BF the Blowpipe and Raceway 高炉直吹管和回旋区煤粉燃烧数学模型
