In many practical applications, people need a kind of desirable stabilizing burner, to guarantee in various wind outside providing stable combustion flame under the situation of wind-force even violent storm and extreme turbulent flow.These application comprise the Olympic Games or other sports meet torch, celebration fire spot and picnic fire.Yet regrettably, the simple stabilizer of this ideal and structure lacks at present relatively.In general, the retention flame reaches by using bluff body generation backflow or strong eddy flow to form vortex structure, though these methods are applied in the industrial combustion system and are successful, be difficult to be applied in the general daily life but hydrocyclone structure is complicated, all depend on relevant mobile direction and velocity magnitude with size and can simple bluff body produce backflow and produce its shape of back that refluxes.So these methods of having known all have tangible limitation.In order to break through the limitation of these conventional methods, promptly overcome the sensitiveness of corresponding stabilizer to outside flow direction, novel flameholder must produce a kind of backflow vortex structure, it be independent of on the one hand wind outside to, change insensitive to precipitate wind speed again on the other hand.
The key factor that influences flame stabilization is the spread speed of flame front, and this speed is fuel type, the function of air-fuel ratio and turbulivity.To most carbon compound fuel, typical laminar flame speed is below 0.5 meter per second.Although (average flow velocity is than the high magnitude of laminar flame speed) generation retention flame also is possible in turbulent flow, actual flame speed there still is confined to laminar flame speed.By contrast, weather in the blast brutality, instantaneous wind speed often surpasses 20 meter per seconds even reaches more than 100 meter per seconds, in this case, make flame stabilization, the present inventor thinks that its stabilizer need possess the function that can produce an aerodynamics " shielding ": this screening energy protection flame (or the root of flame) is not at least put out in all cases; And also has a low regime that can keep smooth combustion.
Summary of the invention
The purpose of this invention is to provide and a kind ofly do not put out in all cases, and have a gas flame steady burner that can keep the smooth combustion low regime.
