Under normal circumstances,with all the temperature decreasing,the liquid ash will change into softening state,then solid,if the ash maintaining softening state touches the heating surface of diesel fired boiler,the coking will form,to the ash cools down and bonds for the heating surface.The coking will lessen the boiler thermal efficiency, and shorten the service life of the
diesel oil boiler,therefore,this text will deliver the following measures in order to avoid the coking of diesel boiler:

1、Reasonable diesel fired furnace outlet temperature
Ensuring that the principle parameters are qualified and also the furnace outlet temperature is less than the coal ash melting point,along with the the steam is qualified,that may prevent the furnace outlet coking of diesel fired boiler effectively.
2、Good mixing of air and fuel
The nice mixing of air and fuel can steer clear of the formation of reduction gas nearby the water wall ,which could avoid the local severe fouling and coking.
3、Helping the primary air speed appropriately
Helping the primary air speed can delay the ignition of fuel,can make the purpose of ignition far away from the burner,the high-temperature zone of flame also travels to the middle of furnace,that may the coking nearby the nozzle.
4、Controlling the load of diesel boiler reasonably
At the same time of reducing the load of diesel boiler,if your combustion seriously isn't stable,the stress reduction really should be suspended,it might continue after combustion stability.
5、Appropriately helping the air volume
The total air volume in to the furnace really should not be under design value,If needed,the oxygen volume needs to be appropriately increased to avoid the serious coking of furnace.
ZG boiler diesel boilers generally can run more in excess of ten years as a result of scientific product design,advanced processing technology and strict quality control,customers' satisfaction is our unremitted pursuit,here you are at e mail us for even more understanding!
