What is the working principle of tubular heating furnace

Time:2022-04-08

What is the working principle of tubular heating furnace?
The working principle of the tubular heating furnace is: the fuel is burned in the radiation chamber of the tubular heating furnace (very few in a separate combustion chamber), and the heat released is mainly transmitted to the furnace tube through radiation heat transfer and convection heat transfer, and then transmitted to the heated medium through conduction heat transfer and convection heat transfer. This is the working principle of the tubular heating furnace.

What are the main parts of the tubular heating furnace?
Tubular heating furnace mainly includes furnace tube, furnace tube connector and support, steel structure, furnace lining, waste heat recovery system, burner, soot blower, chimney, chimney baffle, various butterfly valves, categories (fire viewing door, manhole door, explosion-proof door, cleaning hole door and loading and unloading hole door, etc.) and instrument connecting pipe (thermowell, pressure measuring pipe, fire extinguishing steam pipe, oxygen analyzer connecting pipe and flue gas sampling port connecting pipe, etc.).
