How did early wood-burning cooking stoves work?

Early wood-burning cooking stoves evolved from simple cast-iron boxes into more efficient heating and cooking devices. Initially, these stoves were basic iron containers without grates. As technology advanced, the introduction of grates allowed for better airflow, which was essential for sustaining a fire and cooking food.1

Key mechanisms included:

• Draft Control: Early designs, such as the Franklin stove, utilized sliding doors to regulate the flow of air (draft) through the grate, allowing users to manage the intensity of the fire.1
• Heat Management: To maximize efficiency, some designs incorporated internal baffles to lengthen the travel path of escaping gases, extracting more heat before it exited through the flue.1
• Cooking Surfaces: By 1800, manufacturers began producing round cast-iron stoves specifically equipped with grates designed for cooking food.1

While effective, these wood-burning stoves radiated significant heat, often making kitchens uncomfortably hot. Consequently, they were eventually replaced in the 20th century by steel ranges powered by natural gas or electricity.1
