1·In passing through the turbine in the modern regenerative cycle, some of the steam is bled from the turbine at a series of three or four openings (more or less), for use in feedwater heaters.
在通过现代的再生周期的涡轮方面，一些蒸气以一系列的三或四个开口(或多或少)从涡轮被流血，对于给水加热器的使用。
2·Therefore, using steel spirally fluted tube replacing copper plain tube in HP preheater can be adopted for the boiler feedwater system without copper.
因此，可以采用钢质螺旋槽管替代低压加热器中的铜光滑管，实现锅炉给水系统无铜化运行的要求。
3·According to the characteristics of feedwater process of the drum boiler, an adaptive PID controller with process identification was introduced.
针对汽包锅炉给水过程的特点，采用了一种带在线辨识的自适应p ID控制器。
4·The author described philosophy, causes and precautions for water hammer appearance in steam piping, drum, feedwater piping, economizer, drum draining tube, sub-steam cylinder etc.
叙述了蒸汽管道、锅筒、给水管道、省煤器。锅筒放水管、分汽缸等发生水冲击的基本原理，产生原因和预防措施。
5·Boiler gross efficiency is obtained after corrections of environment temperature, feedwater temperature and coal quality to boiler test efficiency.
对锅炉测试效率进行了环境温度、给水温度及煤种修正，得到锅炉毛效率。
