A paellero,[1]​ also known as a paellero burner, ring, ring or stove, is a gas appliance whose use is initially intended for the preparation of paellas, rice or fideuás and that allows control of the heat, being able to increase or decrease the intensity of the gas flame, as the food is cooked.

It is a stove-type gas burner and is made up of concentric circles through which the flames come out to heat the paella in a more homogeneous way than a kitchen stove would do, since many paellas have a diameter that is too large to be cooked on kitchen stoves.

Sometimes, the utensil is attached to a lifting support bracket to raise the cooking height for comfortable cooking.

Depending on the size of paella to be used, devices with one, two, three or four rings are required.

The paellero works with gas, butane gas in gas cylinders being the most common. Depending on the needs of the cook or the location where cooking is done, the paellero can also be found on the market manufactured for use with propane gas or natural gas. There are also paellero diffusers to attach to the stoves of a gas "Kitchen (appliance)" stove.

The spaces designed to cook paella, generally prepared with brick or concrete, are also called paelleros, and in them you can cook both with wood and using gas paella burners.

In its beginnings at the end of the century, Valencian style rice was cooked in a paella over a wood fire (there were no ovens in homes). It was cooked with orange wood that added a characteristic smell and flavor to the rice. To achieve the correct hardness and texture of the rice, we had to control the fire: if there was too much broth left over, we had to add more wood to the fire to fuel the cooking, or if we had little broth, we had to set aside wood so that the cooking would be slower.

Although gas began to be installed in streets and homes in the century, butane cylinders did not begin to be marketed in Spain until 1957.[2]​.

In that decade, companies that manufacture paellas and paella pans were founded, such as Vaello Campos and Belseher (1950), Paelleras el Cid - Garcima (1954) and later Flames VLC (2000s).
