PARTICULATE MATTER GENERATOR AND COLLECTOR

摘要

An apparatus for generating and collecting particulate matter derived from combusting a carbon-containing fuel in oxidising gas comprises a fuel burner with a nozzle in which the nozzle is housed in a container. The container has a gas inlet and a gas outlet; the gas outlet connects with a conduit for transporting the ga s to atmosphere which is associated with means for forcing gas to flow from the g as inlet via the container and the conduit to atmosphere. Located within the conduit is a station for collecting particulate matter from gas flowing through the conduit. The gas flow-forcing means is controlled in response to a detected gas flow rate at the gas inlet to ensure the rate of gas flow at the gas inlet is maintained at a desired rate, thereby to promote particulate matter formation. A method for collecting particulate matter derived from combusting carbon-containing fuel is also disclosed.
