The cyclone separator comprises a cyclone body having a first end and a second end with a sidewall extending therebetween. The cyclone body defines a cyclone gas inlet for receiving the particle-contaminated gas stream. A cyclone gas outlet is for discharging the clean gas stream. A centripetal accelerator is proximate the cyclone gas inlet to induce centripetal acceleration of the particle-contaminated gas stream. The sidewall defines a discharge opening between the first end and the second end for discharging separated particles from the cyclone body. The discharge opening has a leading edge and a top edge in relation to a flow path of entrained particles within the particle-contaminated gas stream. The top edge extends at an acute angle relative to the leading edge. ## Claims ### Claim 1 A cyclone separator for separating gas and entrained particles from a particle-contaminated gas stream, said cyclone separator comprising: a cyclone body having a first end and a second end with a sidewall extending therebetween, said cyclone body defining a cyclone gas inlet for receiving the particle-contaminated gas stream and a cyclone gas outlet for discharging a clean gas stream from said cyclone separator;
