Abstract

Abstract. Purpose. Measuring the flow rate of hot gas and the related consumption, one of the most popular technique. Based on the measurement method marker proposed method of determining the exit velocity of the pellet combustion burner. Methodology. This paper describes the design of the measuring area. The horizontal part of duct cylindrical portion. It has two holes are mounted on the input light-owners. Holders of ceramics, which are located in the photo sensor measurements serve as thermal insulator. Provided focusing slit that, without limiting angle cross section duct, prevents sparks flying from the far turn on the photoreceptor. This ensures separation group sparks. Two sensor located at a distance of 50 cm from each record flying sparks and using simple circuits fed to the input of multi-channel oscilloscope. Oscillogram from two photo sensor in the form of processed digitization krosskorrelyatsionnoy function. Results. The technique of measuring the speed of high-gas mixture. The design of the photo detector. The method of measuring the speed of the gas mixture used in the research and testing various designs pellets burners. The scientific novelty and practical significance. This method of determining the velocity of the coolant can compete with traditional methods of measurement, winning their compactness, low cost and minimal interference in the duct device.
