Study on insulation effect of hollow riser
According to the air insulation, the use of riser hollow way to reduce the riser heat transfer, improve the riser insulation effect. In the experimental simulation, the corundum brick inner and outer wall and the air gap temperature were measured. The optimal air gap is 25 mm from the heat transfer...

| description | According to the air insulation, the use of riser hollow way to reduce the riser heat transfer, improve the riser insulation effect. In the experimental simulation, the corundum brick inner and outer wall and the air gap temperature were measured. The optimal air gap is 25 mm from the heat transfer theory and the outer wall temperature, but the insula- tion effect is not obvious. To further explore, proposed in the inner and outer walls to 25 mm as a unit into the insula- tion board improvement measures. The results show that the insertion of the insulation board can greatly reduce the temperature of the outer wall and improve the insulation effect. When inserting a heat shield, the heat flow can be reduced by about 50 %. With the increase in the number of inserts inserted, the insulation effect is gradually increased. |
