Stainless Steel Hot Gas Filter System for Coal Gasification

Coal gasification is an extraordinary process transforming coal entirely into valuable gas through dynamic heterogeneous gas-solid reactions. The core of this process involves the interaction of coal's carbon content with steam at impressive pressures below 10 MPa and soaring temperatures exceeding 750°C. This results in the creation of "synthesis gas," a potent combination primarily composed of CO and H₂ with smaller, yet significant amounts of CO₂ and CH₄, which may vary based on specific process conditions. However, traces of unreacted pulverized coal persist within the synthesis gas. If left unchecked, these can impede subsequent device operations. The remarkable high-temperature gas-solid online backflush filter utilizes sintered porous metal cartridges as its resilient filter elements. These elements withstand both high temperatures and pressures, ensuring the efficient removal of particles from the gas stream, safeguarding the downstream system.
