Claim:
1. A combustion experimental apparatus comprising: a test tube in which flames are formed and in which an internal flow path thereof has a diameter less than a flame-quenching distance in a normal temperature; a supply device to supply a premixed gas produced by mixing fuel and oxidizing agent into the test tube; a flame position-obtaining device to obtain positions of flames inside the test tube; and a temperature-adjusting fluid supply device to cause a temperature-adjusting fluid to flow along the test tube, wherein the temperature-adjusting fluid supply device includes: wherein the heater is formed into a cylindrical shape surrounding the first end of the test tube, wherein the guide part is formed into a tube shape surrounding the test tube, and an end of the guide part in an axial direction thereof contacts an end of the heater in an axial direction thereof, and wherein the temperature-adjusting fluid supply device is configured to cause the temperature-adjusting fluid to flow from the first end toward the second end of the test tube through a space between the test tube and the heater and a space between the test tube and the guide part.
