Novel ignition temperature measuring device for experiment

Abstract

The invention discloses a novel ignition temperature measuring device for experiment, aiming at providing an ignition device which ignites fuel only by using heat generated by an ignition wire. The device disclosed by the invention comprises an ignition wire, an ignition power source and an ignition platform. A first ignition hole, a second ignition hole, a first temperature measuring hole and a second temperature measuring hole are arranged on the ignition platform. An ignition temperature measuring cylinder is arranged on a bracket above the center of the ignition platform and is provided with a small hole and a thermocouple, and the thermocouple is connected with a thermometer through the first temperature measuring hole and the second temperature measuring hole on the ignition platform via a lead wire. The ignition wire is arranged above the ignition temperature measuring cylinder, two ends of the ignition wire are fixed at a first ignition column and a second ignition column which are externally sleeved with a bracket, a pressure spring and a fastening rotary sheet respectively. The first ignition column and the second ignition column are fixed on the ignition platform and are connected with the ignition power source respectively through the first ignition hole and the second ignition hole on the ignition platform, and the ignition power source is formed in such a manner that a plug, a power-off protector and a contact type voltage regulator are connected via the lead wire. The device disclosed by the invention is mainly used for fuel ignition and temperature measurement during fuel combustion in a laboratory.

Description

technical field [0001] The invention relates to an ignition device, more specifically, relates to an ignition device for experiments that does not require ignition powder to ignite. Background technique [0002] The ignition process of high-energy fuels (such as aluminum / water-based fuels) is of great importance for many combustion and propulsion applications and for revealing the combustion mechanism of high-energy fuels. At present, the ignition methods used in the research on the combustion of high-energy fuels include: chemical ignition, gunpowder ignition, laser ignition and electric ignition. Using chemical ignition, the device is relatively complicated and there are many components, which is not conducive to simplifying the system and improving reliability. The use of igniter needs to select the appropriate ratio according to the combustion characteristics of the fuel. The ignition of gunpowder is to ignite the gunpowder through the resistance wire. The ignition pow...

Problems solved by technology

The use of igniting powder for ignition has great disadvantages: the combustion of igniting powder will produce a large amount of smoke, which not only affects the judgment of the flame shape and flame structure during the combustion of high-energy fuel, but also the combustion products produced by the combustion of igniting powder affect the high-energy fuel.
