Absolutely not. It is too much risky to put a Dutch oven inside another traditional oven for boiling.  The manufacturers of classical Dutch ovens have said that there is a limit for every Dutch oven. An oven can't exceed its temperature limit at any cost.  You can put the necessary heat on a Dutch oven only for slow cooking. The temperature should never go past a hundred degrees to avoid oven failures.  As we all know that water needs more than 100 degrees to start boiling, it is quite impossible to get boiling water from a Dutch oven faster. And you must never put a pre-heated oven inside another oven to escalate the boiling period. It can cause the Dutch oven to burst, which can also lead to a fatal accident.
