Background technique
With the raising of environmental requirement in recent years and the rapid development of internal combustion engine, followed by combining of forming of internal combustion engine, boiler
Ring power station is rapidly developed.In these circulating power stations, the high-temperature flue gas being usually discharged after internal combustion engine acting passes through
High-temperature boiler gas approach, which is discharged into boiler, to be continued to do work.
The gas approach of waste heat boiler is the unique passage for connecting I. C. engine exhaust flue and waste heat boiler heating surface ontology,
The helical form tail gas that gas approach receives engine exhaust carries out dilatation decompression, so that flue gas forms turbulent medium, into pot
Furnace heating surface exchanges heat.In order to consider flue gas flow field uniformity, length is shorter, in the biggish gas approach of pitch angle,
It needs to arrange smoke deflector, to guarantee that the flue gas in flue has good degree of filling and the lesser heat to heating surface
Deviation impact, and then improve heat exchange efficiency.
Since deflector present position flue gas flow rate is very fast, fluctuation is larger, deflector is easily damaged after through a long time operation,
The damage of deflector restraint device is the main reason for causing deflector to damage.Restraint device between deflector and flue tube wall goes out
It now fails, be kept fixed deflector can not during flue gas is run, with continuing for flue gas runing time, deflector will
The effect of water conservancy diversion can not be normally played, flue gas will have an impact being uniformly distributed for heat after flowing through superheater surface, certain
A little heating surface pipes will receive the influence of thermal deviation, or even different expansion creeps occurs, bring to the normal operation of heating surface
Adverse effect, this problem also become an important factor for restricting safe operation of the boiler.
