FIELD: measurement technology.
SUBSTANCE: group of inventions relates to a sampler for sampling a mixture of a medium and solid particles. Sampler comprises ejector (100), and inner pipe (104) extending inside ejector (100), inside outer pipe (106), and intended for passage through ejector (100) creating negative pressure of medium. Ejector (100) may be arranged in mixture (102) of solid particles and medium - gas and/or liquid. Ejector (100) is configured for sampling (110) mixture under vacuum through at least one inlet (108) and sample outlet (110) of mixture through outlet (116) into mixture (102) so that sample (110) of mixture is moved from inlet (108) to outlet (116). Channel (112) for sample is located at end (120) of ejector (100), opposite outlet (116) of ejector (100), and is inserted or located near inner pipe (104). Channel (112) is intended for collecting sample (122) required for measurement from sample (110) of mixture, moving through ejector (100). Solid particles and medium can at least partially be separated from each other in ejector (100) under action of flow and inertia in sample (110) of mixture. Sampling method includes steps of providing (800) flow which creates negative pressure of medium through ejector (100) via inner pipe (104) and outputting therefrom through outlet (116) so, that negative pressure is created inside ejector (100). Method includes collecting (802) sample (110) of mixture, using negative pressure through at least one inlet (108) from mixture (102) and solid particles. Method includes formin (804) flow of sample (110) of mixture together with flow which creates negative pressure of medium through at least one outlet (116) in mixture (102). Method includes collecting (806) sample (122) required for measurement into channel (112) for sample, by separation of solid particles and medium from each other, at least partially, under action of flow and inertia in sample (110) of mixture.
EFFECT: providing continuous sampling and measurement of parameters of combustion process.
