The nature of blast furnace gas
The concept of gas poisoningThe human body in a short period of time to contact a large number of gas, CO and hemoglobin in the blood with the formation of carboxyhemoglobin, causing tissue hypoxia, especially the brain tissue hypoxia, a few seconds will lost activity, this is acute poisoning. The dissociation rate of affinity force of carbon monoxide and hemoglobin and hemoglobin oxygen affinity than 240 times higher.HbCO the ratio of oxygen and hemoglobin is 3600 times slower.
Two, physical and chemical properties and hazardous characteristics of converter gas:The physicochemical properties of 1, converter gas mainly depends on the gas composition, gas properties of different components of different, inflammable and explosive, easy poisoning is one of the three major characteristics of gas poisoning, fire and explosion. Often referred to as the three gas accidents.2, converter gas is a flammable and explosive gas, carbon monoxide explosion limit is 12.5 74.2%. mixed with air can form explosive mixtures, in case of fire, electric spark, high temperature above 650 degrees and glowing metal objects will cause combustion and explosion.3, converter gas is a highly toxic gas, the human body in a short period of time in contact with a large number of gas, will cause tissue hypoxia, so a long time in the gas area, carbon monoxide concentration should not exceed 30mg/m3 (24ppm)
3, blast furnace gas is a highly toxic gas, the human body in a short period of time to contact a large number of gas, CO and hemoglobin in the blood with the formation of carboxyhemoglobin, causing tissue hypoxia, causes acute poisoning. So long time working in the area of gas, carbon monoxide concentration not more than 30mg/m3 (24ppm).
Physical and chemical properties and dangerous characteristics of blast furnace and converter gasThe physical and chemical properties and dangerous characteristics of blast furnace gas:The physicochemical properties of 1 blast furnace gas mainly depends on the gas composition, gas properties of different components of different, explosive, easy poisoning is three. The characteristics of gas poisoning, fire and explosion is usually referred to as the three major gas accidents.2, blast furnace gas is a flammable and explosive gas, carbon monoxide explosion limit is 12.5 74.2%. mixed with air can form explosive mixtures, in case of fire, electric spark, high temperature above 700 degrees and glowing metal objects will cause combustion and explosion.
