空氣過剩系數(shù):增大空氣過剩系數(shù)，可以加速混合，使火焰變短，反之則混合緩慢，火焰拉長。這兩種情況都有一些實際利用的例子。

Air surplus coefficient: increase the air surplus coefficient, can accelerate the mixing, make the flame shorter, and vice versa, slow mixing, flame elongated. There are some examples of practical use of these two cases.

爐子的燃燒器采用的是自動點火器，并帶火焰檢測。在正常點火后，如果突然停電，安全裝置電磁閥自動切斷氣路內(nèi)燃氣供應(yīng)。燃料氣，空氣的相對速度二者之間的相對速度也對混合有極大的影響，速度差越大，混合就越快。此時必需重新開啟電磁閥開關(guān)按鈕，使燃氣重新送入到爐子燃燒器內(nèi)，但是我們在燃燒器上設(shè)計配套的電子打火并帶火焰檢測，只要氣體進入到燒咀內(nèi)電子打火器就會自動打火，點燃氣體燃燒。

The burner of the furnace is an automatic igniter with flame detection. After normal ignition, if the power fails suddenly, the safety device solenoid valve automatically cuts off the gas supply in the gas path. At this time, the switch button of the solenoid valve must be reopened to re send the gas into the burner burner, but we design a matching electronic fire and fire detection on the burner. As long as the gas enters the burner, the electronic lighter will fire automatically and ignite the gas combustion.

靠爐底或水冷金屬梁的上升、前進、下降、后退的動作把料坯一步一步地移送前進的連續(xù)加熱爐。爐子有固定爐底和步進爐底，或者有固定梁和步進梁。

Depending on the action of rising, advancing, falling and backing of the furnace bottom or the water-cooled metal beam, the material is transferred to the continuous reheating furnace step by step. The furnace has fixed furnace bottom and walking furnace bottom, or there are fixed beam and walking beam.
