An explosion occurred in a restaurant in Changchun, and the roadside vehicles were overturned. What caused the explosion? The cause of the explosion was methane in the sewer, which caused an explosion when it met an ignition source. The car overturned unconsciously, and now there are steel bars and mud everywhere because of the methane explosion. The vehicle was seriously damaged, and many cars around it were damaged. It was because this ignition source ignited biogas that it was blown up.

The vehicle was overturned and the explosion was caused by methane explosion.

An explosion occurred in a hotel in Changchun Commercial Street, and many cars and businesses around it were damaged. Even some cars overturned directly, and her husband was blown up in an instant. The explosion of the hotel has been everywhere, and this piece of cement and steel bar has been everywhere. There are no casualties. After investigation and study, it was found that the cause of the explosion was methane explosion, which was suspected to be caused by excessive heat.

The explosion caused by biogas has serious consequences.

It is understood that this hotel suddenly exploded, directly overturning these local cars, and one of the white cars was directly broken. Through on-site investigation and inspection, it is preliminarily determined that the biogas produced by the sewer enters the dining table through the pipeline and meets the ignition source, which directly leads to flash explosion. It seems lucky that there are no casualties at present, otherwise the situation would be very bad.

Biogas explodes when heated, which is why it does.

Many cars and businesses around were seriously damaged, and even some cars were directly overturned, which was a mess everywhere. The streets are full of destruction caused by explosions, resulting in a lot of rubble, wood and sundries. It may be because the methane in the sewer will not explode until it is preheated by the pipeline. There seems to be no casualties in the early morning, otherwise the consequences of the explosion at noon would be unimaginable. Therefore, everyone must take protective measures to prevent injury.
