A dispenser was developed for feeding small particles into a laboratory burner at a very constant flow rate. A positive displacement of a continuously replaced volume of particles is employed combined with a sonic ejector. The combination meets the requirements for good chemical measurements. The system also satisfies the requirements for laser‐Doppler anemometry
