Description
Technical Field
The utility model relates to an igniter, belongs to the technical field of ignition combustion, and particularly relates to an igniter suitable for gas fuel, liquid combustion and solid fuel.
Background
In the industrial furnace combustion technology, the combustible mixture is subjected to ignition combustion by forced ignition. Common form of forced ignition: spark, small flame, hot object, high temperature gas, etc.
Spark ignition is also called spark ignition, is the most common ignition mode in engineering, and is widely applied to devices such as gasoline engines, gas turbines, civil boilers, gas cookers and the like. The spark may be generated by a capacitive discharge, i.e., the second energy stored in the fast-release capacitor; or by induction discharge, both of which include a transformer. And the ignition coil and the magnet are generated in a second circuit. The spark creates a flame in the combustible mixture that is itself capable of propagating. The entire transition from the start of the discharge to the formation of a stable flame is the ignition process.
Igniting a small flame: is an early simple ignition device. The mechanism is to transfer heat from the ignition source to the gas mixture. The small thermal power fire device has simple structure and reliable ignition. The single small fire pilot lamp is wasteful of fuel gas and has the possibility of being blown out by wind.
Ignition of hot objects: the combustible gas mixture is passed over the hot object to cause the local combustible gas temperature to exceed the ignition temperature, thereby igniting the entire combustible mixture. Heating wires/bars are commonly used as hot objects. The heating wire/rod is typically energized with a low voltage alternating current (below 36V) such that the surface temperature rises to ignite the combustible mixture. The heating wire/electrothermal rod material is made of high temperature resistant, oxidation resistant and long service life material, such as platinum, platinum rhodium, nickel chromium, silicon carbide, molybdenum dioxide, silicon carbide, etc.; the electric heating ignition has the advantages of reliable ignition and the disadvantage of needing an external power supply.
