DEVICE FOR INVESTIGATION OF STRUCTURAL MATERIALS FOR IGNITION IN MEDIUM OF GASEOUS OXIDANT, CONTAINING PARTICLES OF VARIOUS MATERIALS (VERSIONS)

摘要

FIELD: power engineering.;SUBSTANCE: invention relates to devices for investigation of structural materials (SM) samples in medium of gaseous oxidant under various pressures and temperatures. Proposed device for investigation of SM samples for ignition in flow of gaseous oxidant, containing particles of various materials, is realised in two versions. Both versions of devices consist of coaxially and serially arranged gas generator equipped with mixing head and units of fuel and oxidant supply, structurally forming adapter, working part comprising investigated sample and equipped with nozzle, and also metre of luminosity of combustion products of structural materials. At the same time in the first version of design structurally forming adapter is equipped with one or more rows of tangential holes, and gas generator, apart from the main unit of oxidant supply is provided with unit for supply of additional oxidant flow, where three-way accessory is installed for portion supply of various materials particles. In the second version of design accessory for portion supply of particles is arranged in front of structurally forming adapter, having axial hole.;EFFECT: development of device making it possible to test models of elements in real structures with initiators of ignition transferred by flow of oxidant gas.;2 cl, 4 dwg
