Specification for hydraulic port and stud coupling using ' o ' - ring sealing and ' g ' series fastening threads 用o型圈密封及g系列紧固螺纹的液压系流入口及连接螺栓规范
Lower inlet style means the dusty flow inlet is situated on the lower part of the bag - house , and the direction of flow is opposite to that of dust precipitastion 下进风是指含尘气体流入口位于袋室下部,气流与粉尘沉降方向相反。
Great difference in pressure for two flow made pressure wave system and it help to extend the delay time for gas in chamber , which increases combustion effusion . second , to increase combustion effusion , the inlet temperature of air and gas should be enhanced in the range of heat releasing in chemical reaction . third , the first work condition is unburned absolutely and the second work condition is burnt in shear layer of inlet and the end of down wall zone in straight segment 对于压力差很大的两股气流,所形成的压缩波系的结构可以增加燃气驻留时间,提高燃烧稳定性;为了提高扩散燃烧的效率,在保证能放热的化学反应温度范围之内,应适当提高燃气及空气的来流入口温度;燃气喷嘴应居于燃烧室轴线上,是改进超音速燃烧室结构的一种思路。
