Help identify this breaker panel config
Not quite:  You have 2 30 amp breakers at 240v, which means 60 amps at 240v and 120 amps at 120. It's an usual configuration, probably for some specific purpose in the past.  Are you sure there isn't another panel that feeds lighting and other 120v outlets?
Regarding 24 amps, vs 30, you are talking about derating for continuous loads (like lighting and heating).  I DK if your equipment is considered a continuous load or not...something for you to investigate. If in doubt, do the derating to be safe.
EDIT: adding to my answer based on @manassehkatx comment...you'll need to get some 15 or 20 amp breakers to run &quot;convenience circuits&quot; from this panel.   You can't turn a 30 amp 240 v circuit into a MWBC.
Lastly your comment about getting a piece of equipment that requires &quot;1750 Watt 30 amp 240 volts&quot; doesn't make a lot of sense to me, perhaps a typo?  Even a derated 30 amp 240v circuit could handle up to 5,760 watts (30 x 240 x 80% = 5,760) so, I'm not sure what the manufacturer is up about.
