【Q&A Question 238】December 14, 2016: Why are explosion-proof doors installed in heating furnaces? The reference answers will be visible after responding; points are awarded by identifying the key points. (Unless otherwise specified, all questions and answers will be based on hydrogenation units.) 1. When the furnace is filled with flammable gases and unburned gases, in the event of a fire, there is a sudden expansion in volume, leading to increased pressure. If the furnace is overloaded, the pressure inside rises, and the explosion-proof door will open automatically. This prevents damage to the furnace body. Explosion-proof doors are installed to ensure the safety of the equipment.

When the furnace is filled with flammable gases and unburned gases, an explosion will cause a sudden increase in volume and pressure; or if the furnace is overloaded and the pressure inside rises, the explosion-proof door can open automatically, thereby preventing damage to the furnace. Explosion-proof doors are installed to ensure the safety of the equipment.
Before the heating furnace is ignited, if its furnace chamber is filled with flammable gases, an explosion can occur upon exposure to an open flame or static electricity. The purpose of installing explosion-proof doors on the heating furnace is to prevent excessive damage in the event of an explosion and to reduce any secondary hazards resulting from such accidents.

The purpose is to prevent excessive damage in the event of an explosion in the heating furnace.
It automatically activates pressure relief in the event of a furnace explosion, reducing the destructive impact of the explosion on the boiler and preventing damage to the furnace’s water wall, furnace walls, and flues.
Before the heating furnace is ignited, if the furnace chamber is filled with flammable gases, an explosion can occur upon contact with an open flame or static electricity. In such cases, the explosion-proof door opens, allowing the pressure inside the furnace chamber to be released rapidly and preventing damage to the furnace. It can be seen that the purpose of installing explosion-proof doors in heating furnaces is to prevent excessive damage in the event of an explosion in the furnace.

Prevent excessive pressure in the furnace from causing an explosion
In the event of a flash explosion or a more severe accident, the explosion-proof door can open automatically to release pressure and prevent damage to the furnace body
