The ignition gun EHE-20-B-1-18H-S is a high-energy ignition device specially used for pulverized coal boiler micro-oil ignition system. It plays a vital role in the boiler startup process, which can effectively reduce fuel consumption while ensuring stable ignition and safe operation of the boiler.

Product Features

• High-energy ignition: EHE-20-B-1-18H-S adopts high-energy ignition technology, which can generate powerful electric sparks to ensure reliable ignition under various harsh conditions.

• Strong adaptability: The ignition gun is suitable for a variety of coal types, including bituminous coal, lignite, lean coal and mixed coal, etc., which can meet the ignition needs of boilers of different capacity levels and furnace types.

• Energy saving and high efficiency: When the new unit is put into operation and the cold furnace is started, the fuel saving rate can reach more than 75%~90%, which has the advantages of low investment and fast return.

• Stable combustion: equipped with a flame detection device, it can monitor the flame state in real time to ensure the stability and safety of the combustion process.

• Simple structure: The system has a compact structure, easy operation, small maintenance workload, and reduced operating costs.

Working principle

The ignition gun EHE-20-B-1-18H-S is powered by a power supply to convert electrical energy into high-voltage electrical energy. When the voltage on the capacitor rises to the breakdown voltage of the discharge tube, the discharge current passes through the discharge tube, choke, and shielded cable until a high-energy arc spark is formed in the gap between the semiconductor nozzles, thereby igniting the fuel.

Application field

The ignition gun EHE-20-B-1-18H-S is widely used in coal-fired boilers in the power, steel, metallurgy, petrochemical and other industries. It is not only suitable for the ignition system of newly built boilers, but also can be used for the transformation of existing boilers to help users achieve the goal of energy conservation and emission reduction.

System composition

In addition to the ignition gun EHE-20-B-1-18H-S, the micro-oil ignition system also includes a micro-oil coal powder burner, a fuel system, a combustion-supporting air system, a cold furnace pulverizing system, a control system and auxiliary systems. These components work together to ensure the smooth progress of the entire ignition process.

Installation and maintenance

During installation, ensure the correct position and connection of the ignition gun to avoid damage to the equipment caused by high temperature areas. Regularly check the electrodes and insulating parts of the ignition gun and replace the worn parts in time to ensure the long-term stable operation of the equipment.

The ignition gun EHE-20-B-1-18H-S has become an ideal choice for the micro-oil ignition system of pulverized coal boilers with its excellent performance and wide range of applications.
