Oxygen content, carbon monoxide content feedback system
Under standard conditions, pure carbon monoxide (CO) is a colorless, odorless, and non-irritating gas. The relative molecular mass is 28.01, the density is 1.25g / l, the freezing point is -205.1 ℃, and the boiling point is -191.5 ℃. The solubility in water is very low, very difficult to dissolve in water. The explosion limit when mixed with air is 12.5% ~ 74.2%. Carbon monoxide is very easy to combine with hemoglobin to form oxyhemoglobin, so that hemoglobin loses its oxygen carrying capacity and role, causing tissue suffocation and death in severe cases. Carbon monoxide has a toxic effect on tissues and cells throughout the body, especially on the cerebral cortex. CO is present in metallurgy, chemistry, graphite electrode manufacturing, household gas or coal furnaces, and automobile exhaust, so it is important to control carbon monoxide content in the field of industrial burners.
Therefore, the carbon monoxide content and oxygen content are very important for safe combustion. The monitoring of carbon monoxide content and the management of its content feedback system are very important.
Carbon monoxide content feedback system:
Carbon monoxide gas detector is an instrument tool for gas leakage concentration detection, including: portable gas detector, hand-held gas detector, fixed gas detector, online gas detector, etc. Gas sensors are mainly used to detect the types of gases present in the environment. Gas sensors are sensors used to detect the composition and content of gases.
It is generally believed that the definition of a gas sensor is based on the detection target, that is to say, any sensor used to detect gas composition and concentration is called a gas sensor, regardless of whether it is a physical method or a chemical method. For example, sensors that detect gas flow are not considered gas sensors, but thermal conductivity gas analyzers are important gas sensors, although they sometimes use generally consistent detection principles.
