Stove

A stove makes heat.

It helps us cook food. It can also keep us warm.

Long ago, people used open fires. They put pots on stones to cook. Some people still use open fires today.

Stoves can be made of stone or metal. Many stoves use wood for fuel. Some stoves use gas or electricity.

Some stoves are built to be clean. They help keep the air fresh. This is good for our world.

New stoves are always being made. They help us cook in new ways. Stoves are very helpful tools.

A stove makes heat for cooking or warming a room.

Long ago, people used open fires. They might use stones in a circle to make a hearth.

They put pots on stones to cook food. Some people still use open fires today.

Many stoves use different fuels. Some burn wood or coal. Others use natural gas or electricity.

Early metal stoves were often made of cast iron. Benjamin Franklin helped make heating stoves popular. He made the Franklin stove in 1742. It used a grate to burn wood. It also had a path for hot gases. This helped heat stay in the room.

Modern stoves are very different. Some use induction. This is a way to make heat with electricity.

Scientists also work to make cleaner stoves. They want to stop air pollution. Some stoves use filters to clean the smoke. This helps keep the air fresh and safe for us.

A stove is a helpful device used to make heat. People use them to cook yummy food or to warm up a room.

Stoves can work in many different ways. Some use wood, coal, or gasoline to make a fire. Others use natural gas or electricity to create heat.

Most stoves are made from strong materials like steel, stone, or cast iron. Scientists are always working to make new, cleaner designs. They want to stop air pollution from the smoke. Some new stoves use special filters to clean the exhaust gas.

Long ago, people did not have metal stoves. They cooked over open fires for nearly two million years.

They might have started fires by hitting rocks together. Some people made a hearth by putting stones in a circle. Eventually, people put pots on a support made of three stones. This three-stone stove is still used in many places today.

Other cultures, like the Romans, used stone or brick ovens to bake bread. These old ovens were a lot like the pizza ovens we see now.

Metal stoves changed how we heat our homes. In 1642, the first cast-iron stove was built in Massachusetts.

Later, Benjamin Franklin designed a famous stove in 1742. He called it the Franklin stove. It used a metal grate to burn wood more easily. It also had sliding doors to control the air flow. The hot gases traveled through a winding path inside the stove. This kept the heat in the room instead of letting it escape up the chimney. This design used much less wood than a regular fireplace.

As time went on, new kinds of fuel became popular. James Sharp invented the first commercial gas stove in 1834.

Gas stoves were easier to use than wood stoves. In the late 1800s, electric stoves began to appear. Thomas Ahearn showed how electricity could cook a whole meal in 1892.

Later, people started using induction technology. This uses electricity to make heat very quickly. Westinghouse worked on these stoves in the 1970s. They even made a special version called the Cool Top 2.

Today, you can find many different types of stoves in homes. Some use induction to cook safely and quickly.

You might see a large steel range in a modern kitchen. In some cold places, people still use big stone stoves.

These thick stone stoves can hold heat for a long time. This is similar to how a heavy blanket stays warm. Whether they use gas, wood, or electricity, stoves help us eat and stay cozy.

A stove, also known as a range, is a device designed to generate heat. This heat is used for local heating or for cooking food.

Stoves can operate using many different types of fuel. Common fuels include natural gas, electricity, gasoline, wood, and coal. Most stoves are constructed from durable materials like steel, stone, or cast iron. Because older designs can cause air pollution, researchers are constantly developing cleaner versions. Some modern designs, like pellet stoves, are specifically made to burn more cleanly.

To understand how a stove works, we must look at the process of combustion. Combustion is the chemical process of burning fuel to create heat. In many stoves, air is introduced to help this process. Air-tight stoves are designed to burn fuel more completely than conventional models. This complete burning reduces the amount of combustion by-products released into the air. Some systems also use an afterburner or a filter to clean the exhaust gas before it leaves the device.

Stoves have evolved through many distinct stages and types. For millennia, people used ceramic clay ovens for cooking. Another important type is the masonry heater, which was developed during Neolithic times. These heaters are designed to allow complete combustion by burning fuel at full temperature. They have a large thermal mass, which means they can store a lot of heat. This captured heat is radiated over long periods without needing constant firing. Because of this, the surface of a masonry heater is generally not dangerous to touch.

The history of cooking begins with open fires used nearly two million years ago. During the Paleolithic era, roughly 200,000 to 40,000 years ago, humans built primitive hearths. These were often simple circles of stones used for warmth and food. Most open fires are only about 30% efficient on average. Eventually, people began placing vessels on supports like a base of three stones. This three-stone stove is a design that is still widely used around the world today.

Metal stoves changed how people heated their homes and cooked. In 1642, the first cast-iron stove was built in Lynn, Massachusetts. Later, in 1742, Benjamin Franklin designed the "Pennsylvania fireplace," now known as the Franklin stove. This device used a grate to burn wood and sliding doors to control the draught, or air flow. It featured a labyrinthine path for hot exhaust gases. This path allowed heat to enter the room instead of escaping up the chimney. The Franklin stove was very efficient, requiring only one-quarter the fuel of a regular fireplace.

As technology advanced, new fuels like gas and electricity became common. James Sharp invented the first commercial gas stove in 1834. Gas stoves became popular because they were easier to maintain than wood or coal models. However, indoor nitrogen dioxide (NO2) from gas stoves can exceed safety benchmarks set by the EPA and WHO. Electric stoves also gained popularity after the advent of home electricity. In 1892, Thomas Ahearn demonstrated a meal prepared entirely with electricity.

Induction technology represents a modern leap in stove design. The first patents for induction stoves appeared in the early 1900s. In the mid-1950s, General Motors showed demonstration units that could heat water with a newspaper in between. Modern implementation in the United States began in the early 1970s. A team at Westinghouse, led by Bill Moreland and Terry Malarkey, developed the Cool Top 2 induction range. These modern stoves are now produced by many companies, including Samsung, LG, and IKEA.
