This utility model relates to the field of well site blowout ignition technology, specifically to a firebreak wall and its blowout pool. The firebreak wall includes a main body and a fire-resistant wall. By using arc-shaped firebricks to construct the fire-resistant wall, when subjected to flame backdraft, the pressure from the backdraft is transmitted along the arc of the arc to the main body, reducing the impact on the lining material between the firebricks. This makes the fire-resistant wall less prone to deformation under flame backdraft, increasing its overall service life. Simultaneously, a strip-shaped cavity is formed between the fire-resistant wall and the main body, acting as a buffer and facilitating heat transfer through an air layer. This helps reduce the probability of deformation and damage during repeated use, further increasing the firebreak wall's service life and reducing maintenance and construction costs. Similarly, a blowout pool using the aforementioned firebreak wall has an extended overall service life and reduced maintenance and construction costs.

The application provides a backdraft explosion simulation device for fire training, and belongs to the technical field of simulation devices. The device specifically comprises a box body, a spraying system, an ignition system, a telemetry system, a control system, a supply system and a feeding system. One of the supply system and the feeding system shares an oil tank, an oil pump and a flame arrester, and is finally separated from a pipe tee to an oil atomizing nozzle. The feeding system comprises an oil path and a gas path. The gas path comprises a manual valve, a flame arrester, an electromagnetic valve, a combustible gas tank and a pipe. The device has a simple structure, is convenient to operate, and further reduces pollution.
