What is the use of heat tracing in the skirt of coking coke tower?
Thread Content
As mentioned, I hope you can enlighten me, thank you.
We have been putting it into use since the start of construction. Luoyang Institute can flexibly adjust the circulation ratio, 9-meter coke tower, 1.4 million tons/year；
A heating coil is installed at the weld between the skirt and the cylinder to reduce the temperature difference during operation, thereby reducing temperature difference stress. In addition, a heat box should be installed between the upper part of the skirt and the coke tower cone. This heat box can reduce the heat loss at the weld where the skirt and the cone are connected. When the coke tower is operated, it can effectively reduce the temperature gradient there, which means it can reduce the thermal stress there and prevent cracks in the weld there.
The heat tracing of the group seats is to reduce the damage caused by thermal stress to the welds of the group seats and prevent the welds from cracking.
By heating the skirt, the temperature of the skirt can be kept at the same thermal temperature all year round, and the skirt will be in a state of thermal stress relaxation for a long time. . . It can also shorten the temperature gap with the coke tower, reduce the temperature gradient, and avoid welding damage when the coke tower is extended or shortened. . . :lol
Because the coke tower operates intermittently, the skirt of the coke tower is often affected by cold and heat. If there is no heat tracing, the skirt of the coke tower will be damaged. The use of heat tracing can make the skirt of the coke tower evenly heated and reduce the fatigue damage of the coke tower.
What is the use of heat tracing in the skirt of coking coke tower? This problem is caused by a mistake by the poster. The skirt of the coking coke tower has a protective layer, which is mainly for fire protection and secondarily for thermal insulation. It is to prevent the base of the tower from being burned and the entire tower to collapse when the fire burns.
Plays the role of thermal compensation to reduce temperature changes.
