unburned gas 中文意思是什麼
unburned gas
解釋
未燃氣體-
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
對于壓力差很大的兩股氣流，所形成的壓縮波系的結構可以增加燃氣駐留時間，提高燃燒穩定性;為了提高擴散燃燒的效率，在保證能放熱的化學反應溫度范圍之內，應適當提高燃氣及空氣的來流入口溫度;燃氣噴嘴應居於燃燒室軸線上，是改進超音速燃燒室結構的一種思路。 -
Taking the soft ? sensing of oxygen content in flue gas, unburned carbon content in fly ash and coal load in ball mill as examples, we emphatically analyze the current status, modeling method of their soft ? sensing and the secondary variable selection in the soft ? sensing ; and also summarize some other thermal parameter soft ? sensing techniques in our country, which is a guidance for the development of the thermal parameter soft ? sensing technique in power plant, and has some value for the optimization of thermal control systems
以煙氣含氧量、飛灰含炭量、球磨機負荷為例，著重分析和總結了其測量的現狀、軟測量建模方法和二次變量的選取，並概括了國內現有的其他熱工參數軟測量技術，對火電廠熱工參數軟測量技術的發展具有一定的指導意義，對熱工控制系統的優化具有一定的參考價值。
