Probably work pretty good.
Before my dad passed, he told me how they drove the enemy out of the tunnels/caves during the WWII invasion of Okinawa: Flame throwers.

My Father in Law was overhead of the beaches in a USMC Corsair on that day and his observation in regards to flame weapons was that there was about 15 seconds worth of flame in the tank and then you had to lug it all over the battle until you could get a refill because if you dropped it you caught hell from the commanders who wanted to use them further inland as well. Then there was the stark terror of lugging the dang thing before you expended the fuel because all JAP snipers were looking for the guys carrying the tanks and they aimed for the tank not the guy, thus insuring immolation.
