Today, the high temperature tube heater manufacturer will introduce the relevant safety accident case in detail, what are the reasons for the explosion in the furnace of the high temperature tube heater? As long as we know the reason, we can take effective measures to prevent the occurrence of safety accidents.
1. In the ignition and start-up stage of the furnace, the fuel in the fuel pipeline or combustible materials in the furnace safety management tube leak into the furnace, especially the gas fuel (gas and natural gas are used more), which may form explosive mixture with air to reach the explosive limit concentration; When the ignition violates the operating rules (mainly does not use the steam to purge the furnace in accordance with the regulations, the combustible gas is not cleaned), the gas fuel will gather and form explosive mixture.
2. The second is that the burner's flame suddenly goes out and is not found in time, and when the fuel continues to be supplied, an explosive mixture will form with the air and explode when the concentration reaches the limit of explosion. Fuel oil with water, low temperature, less oil, atomized vapor; The fuel oil pressure fluctuates greatly; Water is stored in the gas fuel line or the gas fuel itself carries water; Improper opening of damper; Temporary interruption of feed; Failure of the induced draft fan or blower is the main cause of flameout.
3, the third is gas fuel with oil, fuel nozzle serious oil leakage, too high temperature fuel oil gasification can safely manage the formation of explosive mixture.
