Description

An environmentally friendly intelligent burner control system

technical field

The invention relates to the technical field of environmental protection treatment equipment, in particular to an environmental protection intelligent burner control system.

Background technique

Substance combustion can be divided into complete combustion and incomplete combustion. When a substance is burned to produce new substances that cannot continue to burn, it is called complete combustion; when a substance is burned, it produces new substances that can continue to burn, and it is called incomplete combustion. The reason why there are two different forms of combustion of substances is mainly because the conditions under which the substances are burned are different. When a substance is burned, if there is sufficient air (or other oxidants), complete combustion will occur, otherwise, incomplete combustion will occur. Generally, the fuel is fully burned to form gases such as carbon dioxide, and insufficient combustion will produce carbon monoxide and the like. of toxic gases. A large amount of waste gas is generated in the production process of the factory, and the staff needs to discharge reasonably according to the emission standards for carbon monoxide and nitrogen oxides. However, the current intelligent burner control system can only control the combustion temperature and cannot adjust the emission of flue gas content. , bringing trouble to the workers; in addition, because the Environmental Protection Bureau has not yet been able to know the on-site combustion emissions, after the network is connected, the Environmental Protection Bureau can understand the emissions in real time.
