Description :

　　Physical explosion: an explosion that occurs when a liquid turns into a gas or when a gas rapidly expands, causing a rapid increase in pressure and greatly exceeding the maximum pressure of the container.

　　Chemical explosion: an explosion that occurs when a substance undergoes a chemical reaction, producing a large amount of gas and high temperature.

　　Explosion limit: The high or low concentration of combustible gases, vapors, or dust that can explode when mixed with air upon contact with fire.

　　Explosion upper limit: a mixture of combustible gases, vapors, or dust with air that can cause high concentrations of flame propagation.

　　Lower explosive limit: a mixture of flammable gases, vapors, or dust with air at a low concentration that can spread flames.

　　Characteristics of dust explosion:

　　(1) Multiple explosions are a characteristic of dust explosions;

　　(2) The small ignition energy required for dust explosions is relatively high, making it difficult to ignite on hot surfaces;

　　(3) Compared with right-handed gas explosions, dust explosions have a milder increase in pressure, longer duration of higher pressure, greater energy release, and stronger destructive power.

　　The basic principles of fire extinguishing can be summarized into four aspects: cooling, suffocation, isolation, and chemical suppression.

　　A fire turret is a firefighting device fixed in a specific location, which can generally be remotely and on-site controlled. The tower is divided into one or two rooms. There are fire water bubbles and foam monitors. In case of a dangerous situation, the fire water bubble or foam monitor can be started at the control room console or both, and the corresponding gun barrel can be moved up, down, left, and right remotely to adjust the posture to extinguish the fire and cool down the fire point.

　　In general, the fire turret is a double platform, with foam monitors installed on the upper platform and water monitors installed on the lower platform; There are also three platform (or multi platform) fire turrets, with foam monitors installed on the upper platform, water monitors installed on the middle platform, and dry powder monitors installed on the lower platform. This is mainly determined by the injection characteristics of different extinguishing agents such as foam, water and dry powder, and the longer barrel of the foam gun. In order to ensure the spraying effect of the foam monitor, it is advantageous and necessary to place it on the upper platform. It is precisely because the barrel of the foam gun is long, and its elevation and depression angles are large, it is difficult to install it on the lower platform with a small floor height interval, so it needs to be installed on the upper platform.
