The function of ignition systems in gas turbines is supplying energy for gas turbine starting and continuous operation. Therefore,
effective, reliable and fast ignition is very important in starting sequence and continuous operation. Three types of ignition systems are
used in gas turbines; High tension, High Energy(capacitor-discharge) and torch types. Rayan Energy designs and manufactures all three
types of Ignition Systems according to the customer request.
Some of the outstanding features of the Gas Turbine Ignition Systems which Rayan Energy designs and manufactures, are as follow:
• Reliable & Excellent Performance
• Working with both Liquid and Gas fuel
• Integrated and compact
• Resistant to impacts, dust and moisture
• High thermal stability
• Low consumption
• Permanent operation
• Manufactured according to standards such as ATEX Exd
• Long life
• Easy to install and repair
• Customized to application
The Gas Turbine Ignition System has three main parts:
Exciter Box
The exciter box is a device that produce required energy to maintaining spark at the tip of ignitor. Our exciter boxes for gas turbine
ignition systems are designed and manufactured in two main types, AC Input Supply and DC Input Supply. Also, each of these types can
be single or double. Rayan Energy designs and manufactures ignition systems for various applications. It’s our proficiency.

Cables
A cable transfers the generated energy by exciter box to igniter. The cables manufactured by Rayan Energy, are compatible with very
harsh conditions such as high voltage, high temperature, acidic and chemical environments. Because of this, we call them high tension
cables.

Spark Plugs
Spark plug or ignitor is a device in which the spark is generated on its tip. Many types of ignitors are manufactured in Rayan Energy. In the
first category, we design and manufacture both rigid and mechanism-based ignitors. The rigid igniter has fixed parts, so that it should
be in torch or combustion chamber during the gas turbine starting sequence and operation. The mechanism- based ignitor has moving
parts, so that after starting sequence has been completed, the igniter is pushed out automatically by hot gas pressure. In the second
category, we design and manufacture surface discharge and air gap ignitors. In surface discharge ignitor, a technology named High
Energy is used. In addition to increasing efficiency, this technology reduces the operating voltage of ignition system.
