What should I do if the stove doesn’t burn well?
Thread Content
The atmospheric furnace in our factory uses coal tar, but there are problems every time we start the machine. Always block the furnace nozzle and furnace regulating valve. These phenomena will disappear after more than a week of production, no matter what method is used. I would like to ask if anyone has a good solution or how your factory uses coal tar as fuel oil?
We generally burn dry gas or coked wax oil to reduce residue. Burning coal tar can easily clog the furnace mouth, so it needs to be cleaned frequently.
I have never encountered fuel like coal tar being burned in your factory's furnace, but no matter what raw material is used as fuel oil, there is a possibility that the fuel nozzle will be blocked. You can add a larger filter in front of the flow meter during the next maintenance, so that the regulating valve and nozzle will be less blocked in the future. Also, you mentioned that it is easy to get clogged during the start-up period. It is most likely that the line was not cleaned thoroughly during shutdown or there was welding slag left after a fire occurred during maintenance and was not swept away. Personal opinion, for reference only.
Any heating furnace must use dry gas as a continuous light. Poor combustion indicates liquid inclusion, or poor atomization and clogged nozzles. It is best to use gasoline and diesel as the initial driving fuel.
Strengthen atomization, increase fuel temperature, and control appropriate oxygen concentration
ask: 1. Whether the steam contains water (the steam may contain water when the work is first started, causing the atomization effect to be poor) ； 2. Fuel oil temperature (low temperature will lead to poor atomization effect and poor combustion effect) ； Second, fuel oil easily drips from the burner, affecting the on-site environment. ； Third, the nozzle is easily blocked) ； 3. The oxygen concentration has little effect (if no black smoke is emitted). It will at most affect the thermal efficiency of the stove and will not cause the burner to become blocked. 4. It may be the cold oil left in the pipeline when starting the car. Therefore, can the cleaning time and cycle time before putting into use be increased to ensure the temperature of the fuel?
