Fireboxes is chambers found on steam vehicles , where fuel is burned in order to heat up water inside boilers .

Coal-powered fireboxes have a firedoor, which can be open to shovel coal inside. The door should be kept closed otherwise, to prevent blowback. Blowback is a dangerous event where exhaust flow is reversed, drawing fire into the cab , potentially catastrophically harming the crew. It happens upon entering tunnels with the firedoor open.

A tűzszekrény belsejében uralkodó hőmérsékleti viszonyokról pontos képet a hőmérőre rátekintéssel kaphatunk. Tüzelni úgy kell, hogy az éppen a vontatási igényeknek megfelelő gőzfejlesztést eredményezze. Alacsony hőmérséklet lecsökkent gőzfejlesztési képességet jelent, míg a túlszított tűz esetén a szén nagy mértékben pazarlódik.

Firebox temperature is controlled by the amount of coal and airflow inside it. Simply having no more coal to burn will cause the firebox to cool down, and adding more coal will warm it up if the airflow is sufficient. The amount of airflow depends on whether the steam is being admitted to the cylinders , but can also be adjusted by the blower and damper controls.

Having the firebox full to the brim with coal is not always the best choice. Too much coal with too little airflow negatively affects fuel efficiency , resulting in a lot of coal particles getting spewed out of the chimney before they’re fully burned. This is what makes exhaust dark. When coal amount is proportional to available airflow, however, it burns cleaner and the exhaust color is bright.

Different types of shovels have different characteristics when it comes to feeding the firebox.

Coal in fireboxes can be dumped manually, with the coal dump lever found next to the firedoor.

-Firebox is a chamber onboard a steam vehicle, where the fuel is burned in order to heat up the water inside the boiler. Coal powered fireboxes have a firedoor, which the engineer can keep open while shoveling coal inside. The door should be kept closed whenever possible. Even though its effect on firebox temperature is minimal, keeping the door open can cause blowback when entering tunnels, a reversal of the exhaust flow that can draw fire into the cab and be catastrophic for the crew. Blowback can be prevented by keeping the door closed, or by maintaining intense airflow when entering a tunnel.
