蒸汽機車 火箱 溫度,在當中燃料 燃燒時,可用的氣流也有著高度影響,因空氣中的氧氣能幫助火焰燃燒。

將氣流引入火箱的主要方法,就是完全打開汽門 ,並將逆轉機 設至完全前進、後退,使車輛運轉。汽缸 使用後的蒸汽將由煙囪排出至大氣,隨著車輛運轉,每次排氣都將在火箱內產生負壓,吸入新鮮空氣。

然而,車輛並不是任何時候都能全力加速,因此車輛有著額外調節氣流的方法:操作「送風器」和「火箱進氣口」。

「送風器」通常通常透過一個閥門進行操作。打開時,將釋放少量鍋爐 中的蒸汽噴出煙囪,以此同樣在火箱內產生負壓,吸入新鮮空氣。以此方法導入的氣流遠遠比不上加速時的量,因此在蒸汽機車靜止時才最有效率

「火箱進氣口」通常透過一個把手操作。關閉(向下推至最底)時將會阻礙氣流,就算車輛仍在加速,還是能大幅度降低燃燒溫度。這是用於不再需要大量蒸汽時,降低蒸氣產生的方法。適時注水 也是一種非常有效的方法。
