1) Furnace fire-extinguishing steam line； 2) The flame arrester prevents backfire ； 3) The perpetual light prevents explosions that may occur when air is introduced again after a gas supply interruption ； 4) Explosion-proof vent door
To ensure the safe operation of the heating furnace, the main safety and explosion prevention measures include: 1) A steam purging line is installed in the furnace chamber to purge any combustible materials from it before ignition; 2) A fire-suppression steam line is provided in the tube bank of the convection chamber, which can be used for protection or to extinguish fires in case of oil leakage or ignition at the elbows; 3) A flame arrester is installed on the gas supply line to prevent backflow that could cause an explosion; 4) A pilot light is placed in the furnace chamber to prevent explosions when gas is reintroduced after a failure in the instruments or other components leads to a loss of gas supply; 5) Depending on the volume of the furnace chamber, a certain number of explosion-proof doors are installed on the furnace body to allow pressure release in case of sudden pressure increases, thereby preventing the furnace from exploding.
① The furnace is equipped with a steam purge line. ② A flame arrester is installed on the gas line. ③ An explosion-proof door is installed on the furnace body. ④ A perpetual light is installed inside the furnace.
1) Furnace fire-extinguishing steam line； 2) The flame arrester prevents backfire ； 3) The perpetual light prevents explosions that may occur when air is introduced again after a gas supply interruption ； 4) Explosion-proof door for pressure relief.
There is a large amount of oil or oil vapor inside the heating furnace, and an open flame exists outside the furnace tubes, making fires and explosions highly likely to occur. To prevent fires and explosions, heating furnaces should be constructed from qualified materials; their design should avoid stress concentration due to thermal expansion and contraction. The piping inside the furnace should be arranged in such a way as to prevent gas blockages. The furnace body should be equipped with explosion-proof doors to facilitate pressure release, thereby preventing damage in the event of an explosion inside the furnace ； When using combustible gases as fuel for heating furnaces, and when the pressure of the fuel gas is ≤ 2 atmospheres and there are no low-pressure protection devices, a flame arrester must be installed between the fuel control valve and the furnace body to prevent backflow in the fuel system. A liquid separation tank should be installed; the condensed gas separated in this tank should be placed in appropriate containers or discharged to a safe location ； In a heating furnace that uses combustible gases as fuel, a \"constant-light lamp\" should be installed. The combustible gas used for this lamp should be supplied through a control valve, which should be located in a place that is easily accessible and manipulable in the event of an accident.
① The furnace is equipped with a steam purge line. ② A flame arrester is installed on the gas line. ③ An explosion-proof door is installed on the furnace body. ④ A permanent light is installed inside the furnace
