TEST BENCH FOR ANALYZING IGNITION AND COMBUSTION OF ORGANO-WATER-COAL FUEL DROP Russian patent published in 2016 - IPC G01N33/22 

FIELD: machine building.

SUBSTANCE: invention relates to experimental equipment, in particular to analyzing heat and mass transfer processes, phase conversions and chemical reaction at ignition of single drops of organo-water-coal fuels which differs in their component composition, in gas oxidizer medium. Test bench comprises a hollow cylinder of quartz glass, which is connected on one side to the injection system for air supply, hole for fuel drop supply, two thermocouples, which are connected to a personal computer through a temperature measuring device, and an exhaust ventilation. Cylinder of quartz glass is arranged on the lower shelf of the supporting metal frame in the form of rack with two horizontal shelves located one above another. One end of the hollow cylinder is connected to the output of the air heater, connected to the high-pressure fan. Other end of the hollow cylinder is connected to the exhaust ventilation by metal corrugated pipe, upper part of the hollow cylinder has two holes. On upper shelf of the support frame, above the first hole of the hollow cylinder there is a coordinate device, on the movable part of which the first thermocouple is inserted to place joint end of the thermocouple with fixed drop of organo-water-coal fuel inside the hollow cylinder. In the second hole of the hollow cylinder the second thermocouple is inserted, both thermocouples are connected to a temperature measuring device, located on the upper shelf of the supporting frame. On outer side of the hollow cylinder high-speed and cross-correlational video cameras, double pulsed laser are installed. Cross-correlational video camera and double pulsed laser are connected to a signals synchronizer. Air heater, high-pressure fan, exhaust ventilation, coordinate device, temperature measuring device, high-speed video camera, cross-correlational video camera, signals synchronizer and analytical balances are connected to a personal computer.

EFFECT: higher efficiency and reliability of analysis.
