The adjustment ratio of ordinary burner is generally about 1: 4.
When the burner is working at full load, the gas flow rate, flame
shape and thermal efficiency can reach the best state, but when the
burner flow is close to its minimum flow, the thermal load is
minimum The gas flow rate is greatly reduced, the flame shape does
not meet the requirements, and the thermal efficiency drops
sharply. When the high-speed burner works below 50% of the
full-load flow rate, the above indicators have a large gap from the
design requirements. Pulse burning is not the case. No matter what
kind of situation, the burner has only two working states, one is
full load operation, the other is not working, but the temperature
is adjusted by adjusting the time ratio of the two states, so the
pulse is used Combustion can make up for the shortcomings of low
burner adjustment ratio. When low temperature control is needed,
the burner can still work in the best combustion state. When the
high-speed burner is used, the gas ejection speed is fast, which
causes a negative pressure to be formed around it, and a large
amount of flue gas in the kiln is sucked into the main gas for full
mixing and mixing, which prolongs the stagnation time of the flue
gas in the kiln and increases The contact time between the flue gas
and the product improves the convection heat transfer efficiency.
In addition, the flue gas and the gas in the kiln are fully stirred
and mixed to make the gas temperature close to the flue gas
temperature in the kiln, improve the uniformity of the temperature
field in the kiln, and reduce the high-temperature gas Direct
thermal shock to the heated body.
