Why does the gas smell

Why does the gas smell

Answer:

The smell of gas"When the cold winter came, the patient in the hospital from time to time there is a gas poisoning by the ambulance siren rushed. Gas poisoning, mild dizziness palpitation, weakness, or remain unconscious, weak breathing, even death may not timely rescue.
Some people put a basin of water in the room or a pot of water on the stove, that can absorb carbon monoxide, this is wrong. Because carbon monoxide is insoluble in water. To prevent gas poisoning, it is necessary to put a chimney on the stove, so that the gas through the chimney to the outside. The other is the best in the window above a scoop, maintains the indoor air circulation.
It is usually said that the main component of gas is carbon monoxide. Burning coal stove in the winter, because the doors and windows are closed, the room is not ventilated, carbon monoxide can not be generated to spread to the outside, people will be poisoned more. Carbon monoxide has no color, no smell, and is inhaled into the bloodstream through the alveoli, leading to the combination of the oxygen that transports oxygen. The combination of carbon monoxide and hemoglobin is two hundred or three hundred times more powerful than oxygen. It holds the hemoglobin tightly, so that it loses the ability to bind oxygen. People will cut off the supply of oxygen, dizziness, palpitation, remain unconscious, and even death. The amount of carbon monoxide in the air reaches tens of thousands of times, people will be poisoned. However, people tend to have an illusion that the gas has a choking nose smell, no smell no smell of gas.
So where does the gas come from? When coal is burning in the stove, air enters the furnace from the lower part of the furnace. As a result, the following carbon can get sufficient oxygen, burn completely, produce carbon dioxide, and produce a lot of heat. It is easy to produce gas when the combustion is incomplete. For example, just lit the stove, or the fire was extinguished, or when the door is closed due to fire, the temperature is relatively low or insufficient supply of oxygen, the combustion is not fully, will produce gas.
