| 1. | And the boiler ' s feedwater and burning control system based on foundation fieldbus is also designed in this paper 本文结合具体工程完成了锅炉给水和燃烧现场总线控制系统的设计。 |
| 2. | Simulation of boiler burning control system was also performed to study the controller ' s self - adaptive fuzzy control by matlab 用matlab对应用模糊自整定pid控制器的锅炉燃烧控制系统模型进行仿真研究。 |
| 3. | Although these two algorithms are mainly to burning control system of boiler , they can also be reference effect on other similar control system 我们所设计的这两种算法主要针对锅炉燃烧控制系统,但对其它类似控制系统也有借鉴作用。 |
| 4. | Equipment has been renovated many times , but heating energy waste is very high for lots of reasons , one reason is burning control level is very low 虽然设备几经更新,但由于种种原因,采暖能耗一直很高,其中锅炉燃烧控制落后是原因之一。 |
| 5. | Because of lower automating - control , the boiler ' s running efficiency is low , and heating energy waste is very high , one reason is burning control level is very low 锅炉,作为北方城市冬季取暖的主要设备,长期以来,由于自动化程度不高,运行效率低,能源浪费严重。其中锅炉燃烧控制的落后是高能耗的主要原因之一。 |
| 6. | It is the foundation of boiler burning control to find optimum excess air coefficient , in addition , it is key to adjust the damper opening and valve opening use fuzzy control algorithm according to the content signal of o2 and co in fume road 寻找最佳过量空气系数是锅炉燃烧控制的基础,而锅炉燃烧控制的关键是根据烟道含氧量、烟道一氧化碳含量信号,调整气风门开度,使过量空气系数保持在最佳值附近。 |
| 7. | Vb6 . 0 is used to realize above - mentioned algorithms and burning control is also simulated through soft . when program being designed , some room has been left for future . according to experiment , we testify the fuzzy control algorithm is right and dependable 我们使用vb6 . 0作为编程工具实现的上述算法,并通过软件模拟的方法,对燃烧控制进行了模拟,在程序设计时为今后和其它类似的系统控制留了扩展余地。 |
| 8. | There are 3 parts of heat loss for gas boiler , including heat emission loss , uncompleted burning loss and fume hot loss , uncompleted burning loss decreases following the increase of excess air coefficient , while fume hot loss increases . it is obvious that there exit an optimum coefficient of excess air which make boiler own highest efficiency which is the purpose of burning control 不完全燃烧热损失随过量空气系数的增大而减小,而排烟热损失随过量空气系数的增大而增大,不难看出,存在一最佳的过量空气系数使得两者之和最小,即使得锅炉的热效率最高,燃烧控制的目的即在于此。 |
| 9. | In this paper , two 50t / h coal - fired boilers " burning control system of 26 # heating station was studied as its thesis , the primary pid controller was improved as its purpose , fuzzy control theory developed rapidly at present was applied as its means . the design scheme is that controlling transducers change rotate speed of supplying coal electromotor , fan , and blower using 8051 micro - controller . it realized computer control of burning process 本文以26 ~ #供热站的2台50t / h燃煤锅炉的燃烧控制为课题,以改进原有pid控制为目的,以当前发展比较迅速的模糊控制理论为手段,提出了采用8051单片机控制变频器改变给煤机、引风机和送风机转速的设计方案,实现了燃烧过程的计算机控制。 |
