Design of Pressure Relief Area of Pulverized Coal Bunker in Coal-to-Oil Enterprise
Abstract: Using the 20 L dust explosion characteristic test system, the maximum explosion pressure and the maximum explosion pressure rise rate of the coal dust cloud were tested. The results show that: the maximum explosion pressure is 0.62 MPa; the corresponding coal dust cloud concentration is 300 g/m3; the maximum explosion pressure increases rate is 54.14 MPa/s; and the corresponding coal dust cloud concentration is 200 g/m3. According to the test results, the venting area of the preparation process of pulverized coal and pulverized coal bunker in the gasifier were calculated. We have selected and designed the explosive equipment, and determined its quantity. The results can provide technical support for the safe operation of coal bunker in coal-to-oil enterprise.
