Closed combustion is a type of furnace that has been around for centuries. It is one of the oldest types of furnaces available and is still used in many parts of the world today. Closed combustion systems have a number of advantages over other types of furnaces, including increased efficiency and safety.
Closed combustion is a type of fire in which the fuel and oxidizer are completely separated until ignition. This allows for more complete combustion, which means less pollution and fewer emissions. Closed combustion systems tend to be more efficient than open combustion systems, making them a popular choice for many industrial applications.
There are several types of closed combustion systems, each with its own advantages and disadvantages. The most common type is the sealed combustion system, in which the fuel and oxidizer are kept separate until they come into contact inside the combustion chamber. This type is popular for residential applications because it is relatively simple and efficient.
Another type of sealed combustion system is the gas-fired sealed combustion system. This type has an external fuel source (such as natural gas) and does not require oxygen from the air to operate.
The third type of closed combustion system is called a semi-closed combustion system. It uses both air and an oxidizer to burn the fuel, and it is popular for industrial applications because it is very efficient. However, this type of system can be more complex to operate than the other types of closed combustion systems.
