SHELL venting cone solution

Thread Content

1. The quality of nitrogen is one aspect. 2. Particularly regarding the material of the venting cones, those used today are all made by sintering metal powders. Sintering of powders presents problems such as low porosity, low pressure resistance, and high resistance. In addition, particle bridging occurs during the sintering process, and this phenomenon further increases the resistance during operation. The resulting sharp increase in pressure drop leads to uneven airflow, causing localized high concentrations within the components, which can easily result in their failure. 3. Recommendations: Use screen sintering instead. 1. The pore distribution is uniform, and the control characteristics regarding flow rate and resistance are stable. 2. It has high strength and rigidity, and is easy to assemble and maintain. 3. It is resistant to high temperatures and corrosion, allowing it to be used in a wide range of environments. 4. It offers excellent mass and heat transfer properties, high efficiency, and low gas consumption. 5. It provides great operational flexibility, facilitates process adjustment, prevents material leakage, and eliminates issues such as breakdowns, short circuits, and blockages, resulting in a long service life ； Sintered metal mesh plates are widely used in coal powder ventilators, as well as for the injection of coal powder to control processes in alumina and ironmaking blast furnaces. Mesh sintering has been in use for decades in such applications, and it represents an ideal alternative to powder sintering.
