Safety Protection Design for the Furnace Chamber of Batch-Type Oil Refining Equipment

The safety protection design for the furnace chamber of batch-type oil refining equipment can be simplified into the following 6 core measures, focusing on the prevention and control of key risks:

Over-temperature Interlock Protection

Install thermocouples in multiple areas of the furnace chamber. When the temperature exceeds the threshold of 850℃, an audible and visual alarm will be triggered automatically, and the fuel supply to the burner will be cut off to prevent burnout of the furnace liner.

Explosion-proof and Pressure Relief Device

Install explosion-proof membranes or pressure relief valves on the top or side. When the pressure inside the furnace chamber rises sharply, pressure will be released rapidly to avoid equipment damage caused by deflagration.

Heat Insulation and Anti-scald Structure

Adopt a composite thermal insulation layer of "aluminum silicate fiber felt + rock wool + fireproof color steel plate" on the outer wall, controlling the temperature of the outer wall below 60℃ to prevent personnel scalding.

Flue Gas Safety System

Install a backfire arrester in the flue to avoid flame flashback, and equip with dust removal, desulfurization and denitrification devices to ensure that flue gas is discharged up to the standard.

Maintenance Interlock Protection

The access door is equipped with an interlock function. When the door is opened, the fuel supply will be cut off automatically and the equipment will be locked to prevent accidental start-up during maintenance.

Emergency Fire Extinguishing Configuration

Equip dry powder or carbon dioxide fire extinguishing devices near the furnace chamber to deal with sudden fires caused by fuel leakage.
