In a specific embodiment of the present invention, fuel gas refers to: can be with air (or oxygen) in certain concentration range
It is inside uniformly mixed to form premix gas, chance is fiery, heated or the gas that can be burnt or explode is contacted with oxidant.It, can in the present embodiment
Combustion gas body includes single fuel gas and mixed combustible gas body, wherein single fuel gas refers to a kind of combustible gas of component
Body, mixed combustible gas body refer to the mixture of two or more fuel gas.Illustratively, such as single fuel gas packet
Hydrogen, ammonia, carbon monoxide and methane etc. are included, mixed combustible gas body includes combustion gas and liquefied petroleum gas etc..Current gas concentration
For the volume fraction of fuel gas in current time air, i.e. the aerial percent by volume of current time fuel gas is dense
Degree.
Combustible gas leakage event can be detected in the following way to be triggered: periodically detecting current environment
Combustable gas concentration, and determine whether to increase with it as detection cycle continues combustable gas concentration；If it is determined that occurring
Combustable gas concentration increases, it is determined that combustible gas leakage event occurs.
If combustible gas leakage situation is not found and solved in time, combustable gas concentration can constantly increase, and increase to
When to a certain degree, it can cause flammable gas explosion.In order to be mentioned to user with alarm before fuel gas does not explode
Show, so that user can take corresponding processing mode according to alarm sounds.Would generally setting monitor concentration by way of come
It realizes, specifically, current gas concentration is periodically detected, if current gas concentration is greater than or equal to monitoring concentration,
Alarm sounds are generated, and send alarm sounds to user.Wherein, monitoring concentration can refer to the report being arranged on combustible gas detector
Alert concentration, is usually indicated with %LEL, concrete meaning be the aerial content of the fuel gas and its in lower explosion limit
Percentage.Usually monitoring concentration is set in the 25%LEL of lower explosion limit hereinafter, the measurement range of general combustible gas detector is
0-100%LEL, above description monitor concentration and are less than lower explosion limit, therefore, can when combustable gas concentration reaches monitoring concentration
