A Dutch oven is a thick-walled cooking pot with a tight-fitting lid. It's great for cooking dishes like stews, braises, and pot roasts that benefit from slow, even cooking and retention of moisture.
Some key features of a Dutch oven:

Thick walls - The thick walls allow for even heating and prevent burning or scorching food.
Tight-fitting lid - The lid seals in moisture and traps steam, which helps the food cook evenly and prevents it from drying out.
Oven-safe - Dutch ovens are oven-safe, so you can start cooking on the stovetop and then transfer to the oven to finish cooking.
Durability - Dutch ovens are very durable and long-lasting, often made of cast iron, enamel-coated cast iron or other heavy materials.

So for a recipe like feijoada which simmers for a long time, a Dutch oven is ideal for cooking it evenly and retaining moisture.  If you don't have a Dutch oven, you can use a large pot with a tight-fitting lid, but you may need to adjust cooking time and liquid amounts.
