Combustible gases refer to substances that can ignite and remain in a gaseous state at room temperature and pressure. For example, hydrogen, acetylene, ethylene, ammonia, hydrogen sulfide, etc. Combustible gases have the general characteristics of gases. A combustible gas of one component is called a single gas; A mixture of two or more combustible gases is called a mixed combustible gas. Combustible gases mixed in a certain proportion in the corresponding combustion supporting medium can cause combustion or explosion under the action of an ignition source. Combustible gas is sprayed from the nozzle at a certain flow rate, and its combustion speed is determined by the diffusion speed of the combustible gas and air.
