Method and the research and measuring installation for determination of wearing resistance of loose materials, preferably oxygen carriers in the high temperature fluidized bed for combustion of energetic fuel

摘要

method and installation for determining the research and measurement of resistance to abrasion loose materials, especially of oxygen in high-temperature fluidised bed for fuel combustion energyintended for use in energy generation, in the process of fuel combustion energy without access oxidant gas, is characterized by the fact that measurements the sample weight loss powdery material.positive medium oxygen during its recirculation in the reactor (r) conducted at temperatures 800u00b0c - 1000u00b0c in the carrier gas from the air chamber (kp) under elevated pressure.a sample of the powdery fixed initial weight is through the flow-through loading (about) in the lid (pc) of the cyclone (cl) to couple opadowej (asld) of wziernikiem (bs)combined with a radius (r), which is subject to repeated circulation in turbulentnym movement of hot carrier gas.what as a result of the free flowing material is raised pressure tube (lwn) to the cyclone (cl), where the separated grains of 40u00b5m are addressed to the filter (f),and grain 40u00b5m are led by the (about) to a pipe opadowej (rop), and then to the reactor (r), where they are included in the recirculation by fixed time interval 1h, 5h, 24h.what sets the mass poreakcyjnu0105 material samples harvested in osadniku (dz) in the reactor (r).on the basis of the difference between the initial sample mass, and mass poreakcyjnu0105 determines loss of weight and abrasion index.
