Description

technical field [0001] The invention relates to a single particle reaction measuring device. [0002] The invention also relates to a single particle reaction measurement method. Background technique [0003] Under the condition of normal temperature, the fuel only undergoes slow oxidation when it contacts the oxidizing agent, but no ignition and combustion process can occur. After raising the temperature of the oxidant to a certain value, the fuel and the oxidant will burn rapidly, and the instant of the change of these two states is called ignition. [0004] Commonly used tube furnaces can only analyze the fuel combustion process from the reaction gas components, and it is difficult to collect the internal temperature of the particles and the combustion image information at the same time. Therefore, the present invention designs a tube furnace-based single particle reaction measurement device and measurement method to overcome the above-mentioned shortcomings, and the pr...
