Ignition of the combustion furnace
Thread Content
When igniting the combustion furnace with fuel gas, first introduce air, and then introduce the fuel gas to ignite it； Should I first supply the fuel gas and then introduce air to start the ignition gun? Which method do you use? What are the advantages and disadvantages of each~~~{:1_90:}
First, introduce air, then ignite, and finally supply the fuel gas.
Why not use another one? Supply fuel gas first, then air, and start the ignition gun~
Prevent flash explosions. The original poster can also understand it this way: in the environment where a lighter is used to ignite something, the stove first has air supplied to it and then fuel gas, with electricity being used for ignition.
It’s okay to let the fuel gas flow in first; there’s no risk of an explosion
It’s the same as lighting a regular furnace; ordinary furnaces simply use flue dampers to regulate the airflow. A furnace explosion can be very dangerous!
For automatic ignition guns, these three processes occur simultaneously: the fuel gas and air are premixed and then sprayed into the gun to generate a flame, just like how oxygen and acetylene are mixed in oxy-acetylene welding. Considering the distance traveled by the combustion gases, by the time the mixture is ejected, the firearm is already firing. They told me that the ionization ignition would occur no later than the introduction of air and fuel gas; just like in a household stove, when you turn it on, the natural gas is released at the same time.
