    摘要:

    在殼牌煤氣化工程中，需要多孔不銹鋼通氣錐/管作為氣體分布元件，以保證煤粉和飛灰的流態(tài)化連續(xù)輸送。本研究針對使用要求，主要研究了粉末軋制和冷等靜壓技術(shù)制備的多孔不銹鋼通氣錐/管的滲透性能和強度。結(jié)果表明，冷等靜壓成形后經(jīng)過燒結(jié)和復燒的通氣錐/管，孔隙度在32%-35%范圍，最大孔徑為20 μm，通氣錐的整體耐壓強度都大于2.5 MPa，符合殼牌煤氣化技術(shù)流態(tài)化輸送的要求。

    Abstract:

    In the Shell Coal Gasification Process (SCGP), porous stainless steel cone is used as a gas-distributor to make pulverized coal entering fluidization which can insure the continuous transportation of coal powder and improve the combustion efficiency. In the service conditions the porous cone must have not only high and uniform permeability, but also a proper strength. This study focuses on the preparation of porous stainless steel cone and tube with high performances such as permeability and strength etc. for applications. The porous cone/tube with 32%-35% in porosity, 20 micron in maximum pore size was prepared by CIP. After welding and sealing, the breaking pressures of cone/tube are larger than 2.5 MPa which meet the requirements for fluidization transportation of coal powder in SCGP.
