Hello Everyone, im pretty new to houdini and especially the fire solver and im having a couple of issues i hoped i could get some help on

1 ive managed to get the particle system that ive set up to emit fuel as i had hoped however im having difficulty getting it to ignite. id like to ignite the fuel from the original source of the fire sim (a tube at the far left). i experimented doing it just by putting tempeture into the negative values after a fixed number of frames but i wanted to see what you would all recommend

2 is there a way to get the fire/burn to inherit the velocity of my particles/spheres?

thanks in advance the file is attached!
