Analysis of ignition necessity of industrial gas burner

KROM gas burner is a fast burning device widely used in industrial kilns. The fuel and air can be completely burned in the combustion chamber after mixing, and the high-temperature flue gas formed can be ejected from the nozzle nozzle at a high speed with the aid of expansion pressure.

Necessity Analysis of Ignition Nozzle

1. From the perspective of safety, large oil supply, air distribution and air volume of high-power burners may lead to deflagration failure due to improper ignition.

2. In terms of ignition efficiency, the spark generated by the electrode under the action of the igniter is small, and it is difficult to ignite in the environment of large air flow and wind pressure. The small ignition burner must be ignited first, and then ignited successfully.

3. Starting from the pursuit of technology, how to better meet the needs is the goal of each production enterprise. The ignition burner is integrated with the natural gas burner and equipped with an external control system, which is simple and convenient.

It can be seen that the position of ignition device in current industrial kilns cannot be underestimated. However, this device only provides high temperature ignition source, and the combustion device can successfully ignite. It is also necessary to consider whether the conditions for mixed gas and flame propagation around the ignition source are met. Do not blindly try to ignite continuously. Different customers are provided with installation and wiring instructions, ignition operation procedures and precautions. If there is still doubt, special personnel can be arranged to guide the installation and commissioning. Because the gas consumption, air pressure and air pressure of different types of natural gas burners are very different, only highly qualified people can be familiar with the ignition conditions of each type of burner in different industrial furnaces.

Characteristics of industrial gas ignition burner: high speed burner can completely burn fuel with ultra-high heat load. The combustion chamber of the burner itself is very small, and the fuel can basically be completely burned, so the volumetric heat intensity of the burner is very high, which can reach 6.28 × 108kj(m3h)。 At the same time, due to the high flow rate of combustion gas, the convection heat transfer is strengthened, and the uniformity of furnace temperature is improved. Practice shows that when the temperature of natural gas furnace is 850~1150, the temperature difference is ± 7. The atmosphere in the furnace can be easily adjusted to oxidation or reduction. When the excess air coefficient is very high, it can still stabilize combustion. The amount of excess air can reach 50.0, which is 2.5 times higher than that of ordinary burners. The air flow temperature of high-speed burner combustion can be adjusted freely in the range of 200~1800 (excess air coefficient α 1~50), so that the high-speed burner designed and produced can meet the requirements of various gas kilns.
