Multi-functional combustion experimental system

Abstract

The invention provides a multi-functional combustion experimental system, comprising an upper computer, a control system, an air supply unit, an air outlet valve, a safety valve, a sample experiment unit, an exhaust gas collector, an air concentration measuring unit and the like. A combustible matter is placed in the sample experiment unit, then a plurality of gases are flown to the sample experiment unit according to preset ratio through the air supply unit; then the temperature of the sample experiment unit is controlled or an automatic ignition device is controlled to enable the combustible matter to burn; a temperature sensor arranged at the sample experiment unit is employed to measure the combustion state of the combustible matter and space and temperature distribution; When combustion is finished, the combustion products are discharged into the air concentration measuring unit through the air outlet valve; and a plurality of air concentration sensors arranged in the air concentration measuring unit are employed to measure components and concentrations of gases in the combustion products. The multi-functional combustion experimental system of the invention features multiple functions and good universality, can finish multiple experimental working conditions in a single experiment and greatly improve experimental efficiency.

Description

technical field [0001] The invention relates to combustion science experiments, in particular to a multifunctional combustion experiment system suitable for ground environment and microgravity conditions. Background technique [0002] The current microgravity combustion experimental device has a single function and can only carry out one kind of test. For example, research on ignition and combustion characteristics of materials, research on the influence of forced convection and gas components on flame characteristics, research on smoldering mechanism, research on combustion-flow interaction mechanism of premixed flames, research on smoke movement laws and fire monitoring technology, Study on the characteristics of pulverized coal combustion and its pollutant generation. The research methodology for these experiments is to use a single function experimental setup and then conduct the experiment. If another test is to be performed, the test device must be replaced and the t...
