An apparatus includes a sampling probe having a first portion and a second portion. The first portion is configured to penetrate inside a wall of a duct having an inner chamber that is configured to carry a gas stream containing particulate matter therethrough. The first portion is further configured to divert a sample of the, gas stream from the inner chamber of the duet to the second portion that extends from the wall of the duct opposite the inner chamber. The second portion of the sampling probe is configured to direct the sample of the gas stream in a first direction with a second direction corresponding to a direction of the gravitational force of the earth. A first ray corresponding to the first direction forms an angle β with a second ray corresponding to the second direction. The angle β is less than 90 degrees.

A vertical separator system with an enhanced control mechanism which employs one or more micro-adjustment features. The micro-adjustment features include a combination of an air bladder, a mass sensor, and/or a bleed valve.

An airflow separator of the present invention includes: a first column into which gas is introduced from a lower portion and inside which a sample is made to flow; a heavy particle recovery device provided at the lower portion of the first column; and a control device configured to control a wind speed by an amount of gas to be introduced into the first column. The first column has a weak rotational airflow generation mechanism to smooth wind speed distribution in a cross-section of a tube of the first column by making it substantially W-shaped from a portion of a wall of the tube to the center of the tube to another portion of the wall of the tube. The heavy particle recovery device recovers from the sample, heavy particles falling down. The airflow separator recovers emission gas, intermediate and light particles from an upper portion of the first column.
