電極型鍋爐
英文
electrode type boiler-
There are many plants that have the character of time - varying, large delay, large inertia in the process of production of modern power station such as the superheated steam temperature, the reheated steam temperature, the water treatment of boiler and the load regulation. some of them have the strong character of nonlinear and some of them are multivariable coupling systems it is very difficult to obtain good effect of control by conventional pid control. it is necessary to set up the mathematics models of controlled plants if applying control means of modern control theory such as self - adaptive control, optimal control ， decoupling control and predictive control. and these control systems have large calculation and bad character of real time in general. these disadvantages make them be not able to meet the need of real production process and limit the application of them in modern power station. now the generator units are developing towards large capacity and high parameters. many new kinds of generating electricity means are coming into being. the characers of production units of power station become more and more complex but the demand to quality of control becomes more and more strict. the new control means are in bad need to control them effectively
現代電站的生產過程中存在過熱汽溫、再熱汽溫、鍋爐水處理、負荷調節等許多大遲延、大滯后、特性時變的對象，它們中有些還是具有強非線性特性的對象或多變量耦合系統，採用常規的pid控制手段很難取得良好的控制效果。若應用現代控制理論中的自適應控制、最優控制、解耦控制、預測控制等控制手段，則需要建立被控對象的數學模型，而且往往控制系統的計算量大、實時性差。這些缺點使其很難滿足實際生產過程的需要從而極大地限制了其在現代電站中的應用。Directing against state of affairs at present, such as margin of type - selection parameters being selected comparatively large during design stage of air fans for boilers in thermal power plants, the opening degree of air fans in operation being often smaller ( for adjustment of inlet regulator ) or operation at lower revolution speed ( for speed - regulating operation mode ), and efficiency of air fans being lower etc., factors and corresponding measures having to pay attention in margin selection of air fan ' s parameters have been put forward through analysing practical example of retrofitting forced draft fans in one power plant, playing certain positive role for energy - saving and benefit - increasing in power plants
摘要針對目前火力發電廠鍋爐風機在設計選型時參數裕量選取較大，運行時風門開度較小（對入口調節器調節）或低轉速運行（調速運行方式） ，風機效率較低的狀況，通過對某電廠送風機改造實例的分析，提出了在風機參數選擇中的裕量選取需要注意的因素及相關對策，對電廠的節能增效有一定的積極作用。Automatic electrical controls for household and similar use - part 2 : particular requirements for automatic electrical water level sensing controls of the float or electrode - sensor type used in boiler applications
