Coal burner facts for kids
A coal burner is a special machine that burns very fine coal, also known as pulverized coal or powdered coal. This coal is as fine as face powder! The burner creates a controlled flame from this powdered coal.
Coal burners have several important parts. These include a machine that grinds the coal, a main burning section (with a chamber where the burning happens), a system to control how air flows in, and a way to start the fire.
How Coal Burners Work
When a coal burner is used, it usually works with a coal hopper (a container for the coal) and a coal pulverizer. First, coal from the hopper is moved to the pulverizer. The pulverizer then grinds the coal into a very fine powder.
Inside the coal burner, this powdered coal mixes with air. A powerful fan helps to blow this air at high speed. This mix of coal dust and air is then lit by a special igniter, which often uses oil or gas to start the flame. There are two main ways to light a coal burner: either by hand or automatically. No matter how it's lit, the burner needs some kind of fuel, like oil or gas, to get the fire going.
Where Coal Burners Are Used
Coal burners are used in many different industries because they can produce a lot of heat. Here are some examples:
- Annealing: This is a process used to make metals softer and less brittle by heating them up and then letting them cool slowly.
- Boilers: Coal burners provide heat for large boilers, which create steam for power plants or heating systems.
- Cement kilns: They are used to heat huge ovens that make cement.
- Furnaces: These are used for many industrial heating tasks.
- Hot mix asphalt plants: Coal burners heat the materials needed to make asphalt for roads.
- Quenching furnaces: These furnaces are used in metalworking to quickly cool hot metal, which changes its properties.
