Hmmm, what you need is a high-power output to a high-temperature
source. A 9-volt probably will not do it, unless you get really 
cute. See, the power output is limited by the maximum current
out of the battery, which is limited by the internal resistance
of it. 9-volts are very low current devices. 

The nichrome igniters used by rocket hobbyists is probably your
best bet: it heats up very hot, very fast, and lasts long enough
to ignite most rocket engines. Get the ones with the blob of
flammable stuff in the middle, they work better.

What are you trying to ignite, anyway?
