Most irc servers connect by using port 6667. The firewall doesn't allow 1024+ to be used.
Is it possible to bypass this problem by letting the irc server sending all the data using port 80? (which is used for navigating the web if i'm correct)
Is it possible to easy see which ports the firewall accepts and which ports the firewall blocks (doesn't let through)?

Last time I checked irc.hemmet.chalmers.se (now irc.csbnet.se) allows connections to port 80, however you may not be able to access the server depending on where you are from in the world.

most servers will list their ports in /motd
if none of them will work for you, you can use an ssh tunnel.
either use a shell servers' ssh, run ssh at home, or have a friend run an ssh server (the latter 2 are easier to have configured for port 80).
install some form of openssh client (or other ssh that supports this feature). i use cygwin, which comes with openssh.
type something like the following:
ssh -D 500 -p 80 -l username your.sshserver.com
and enter your password.
now, set up your IRC client to use SOCKS4 proxy at localhost:500. this also has the added feature that work can't sniff your IRC traffic

open proxies are not allowed because of security purposes, closed proxies are just fine.

Trying to use irc to port 80 from work often means passing through a http proxy/cache/filter, irc data gets consigned to oblivion through these.
In my case, the company firewall allows outgoing telnet through something called a "raptor proxy" (why i dont know), SSH works through this back home though
Your best bet is to use the chat.efnet.info web client that seiki put up.
