A mixing ignition chamber and a pulse generation tank are connected together through a flame duct, the special flame accelerating duct is added to the flame duct, the flame propagation speed can be obviously increased, and the impact strength of a detonation wave can be enhanced, so that the soot blowing strength of a soot blower can be improved, the better soot blowing effect can be realized, the operating distance is longer, and meanwhile, the phenomena of soot accumulation and water accumulation in the pulse generation tank can be prevented.
Description
First, technical field
The present invention relates to boiler soot-blowing equipment technical field, and in particular to a kind of flame acceleration conduit.
2nd, background technology
Shock wave (pulse) soot blower is proposed at first the eighties in 20th century by Ukraine scientific and technical personnel, its principle be by
This energy carrier of detonation wave, is rapidly transferred to each corner of designated space, to involve by a certain size energy efficient
The mode equipment of disposing the slagging scorification on heated surface at the end of boiler or dust stratification.Detonating combustion is theoretical, is that shock wave (pulse) blows
The theoretical foundation of grey device system design；It is filled in blending tank by the fuel gas that certain proportion is mixed, by height
Can electric spark igniter, first make the combustible gas deflagrating in blending tank, formed with few meters per second or even tens meters of spread speeds
Deflagration ripple, is then gradually converted into the detonation wave of a few kms per second, detonation wave along in the incoming pulse generation tank of flame conduit,
Whole combustion processes are completed in several milliseconds of time, powerful detonation wave is formed and rapidly from transmitting spout discharge, is produced huge
Big thrust and wave energy.Therefore, by the intensity of raising detonation wave, more preferable soot blowing effect can be obtained, and operating distance is more
Far.
The Chinese patent of Application No. 200510126084.4, as combustion-supporting gas, is entered with fuel gas by using oxygen
Row mixing improves pinking intensity of wave, and during oxygen use, itself has danger, easily becomes Equations of The Second Kind dangerous
Source.The Chinese patent of Application No. 201420192442.6 accelerates ring by a kind of taper in pulse generation tank indoor design,
The Chinese patent of Application No. 200510082914.8 pulse generation tank by making spherical, Application No. into
The barrier that 201220023196.2 Chinese patent passes through the configuration Archimedes spiral shape inside pulse generation tank, it is above-mentioned
All of method all simply carries out technological improvement inside pulse generation tank, from for theory analysis, can lift soot blowing effect,
But in specific implementation process, cannot still meet and be actually needed or difficulty of processing is big, high cost.
3rd, the content of the invention
