摘要：

Dense-phase pneumatic conveying experiments of the petroleum coke, anthracite and these two kinds of powder blending were carried out at pneumatic conveying system with pressure up to 4.0 MPa. The effects of powder properties and operation parameter on flow characteristics and conveying stability were analyzed and compared. The results show that the petroleum coke has smaller mass flow rate and worse conveying stability than the anthracite with the similar particle size and conveying condition. The conveying characteristics of blendings of the petroleum coke and anthracite improve gradually compared with the petroleum coke. With the increase of mass proportion of the anthracite in the blendings, the mass flow rate increases correspondingly, while the conveying stability almost remains unchanged. © 2016, Central South University Press.
