Abstract
A sampler including an ejector and a sample channel extending to the ejector, which are placeable in a mixture of particles of a solid and a medium, the medium being a gas and/or a liquid. The ejector includes at least one inlet and an outlet. The ejector takes a mixture sample by using vacuum via the inlet and discharges it via the outlet so as to make the mixture sample flow from the inlet towards the outlet. The sample channel takes a desired measuring sample from the mixture sample flowing in the ejector, the solid particles and the medium being at least partly separable from one another in the ejector on the basis of the flow and inertia in the mixture sample.
Claims16
A sampler, comprising an ejector which is placeable in a combustion chamber and which comprises an inner pipe extending into the ejector to allow a vacuum-generating fluid flow pass through the ejector, and a sample channel which is nested with or adjacent to the inner pipe extending into the ejector and placeable in a mixture of solid particles and a medium, the medium being at least one of the following:
- a gas, a liquid,
- the ejector comprises at least one inlet and at least one outlet,
- the ejector is configured to take a mixture sample by using vacuum via at least one inlet and to discharge the mixture sample via the outlet into the mixture so as to make the mixture sample flow from the inlet towards the outlet and
- the sample channel is configured to take a desired measuring sample from the mixture sample flowing in the ejector, the solid particles and the medium being at least partly separable from one another in the ejector on the basis of the flow and inertia in the mixture sample.
A method for sampling, comprising:
- allowing a vacuum-generating fluid to flow through an ejector in an inner pipe inside the ejector and out via an outlet of the ejector so as to provide vacuum inside the ejector;
- taking a mixture sample, using vacuum, via at least one inlet into the ejector that is placed in a combustion chamber from a mixture of a medium and solid particles, the medium being a liquid and/or a gas;
- bringing the mixture sample to flow with the vacuum-generating fluid flow through at least one outlet into the mixture;
- and
- taking a desired measuring sample into a sample channel nested or parallel with the inner pipe from the mixture sample flowing inside the ejector separating the solid particles and the medium from one another at least partly on the basis of the flow and inertia in the mixture sample.
