 How To Prevent Oil Fired Boiler Superheater Tube Explosion

In oil fired boiler, a superheater is the heating surface used to heat saturated steam or wet steam into superheated steam under corresponding pressure. It is fairly important in oil fired boiler, but if the pipe withstand temperature in excess of material durable strength, fatigue strength or surface oxidation allowable temperature limit, it will burst. In this paper, our engineer shows some measures to prevent the superheater tube explosion.

1. Oil fired boiler temperature and pressure boost should be conducted in strict accordance with regulations, control the speed. According to the provisions do water wall lower header sewage, quickly establish water cycle, timely switch oil gun, ensure heating surface heated evenly, to prevent hemi-combustion, eliminating thermal deviation.

2. Strengthen soot blower and soot blower management to prevent severe fouling in heating surface. If find coking phenomenon in the furnace, timely add soot blowing times, to ensure good water wall heat absorbing; for the heating surface with long-term existence of overheating problem, install thermal temperature measurement point to supervisory and control; ensure accurate expansion indication.

3. Well adjustment in oil-fired boiler combustion can prevent flames skewed; pay attention to coal fineness control, rational wind usage, to prevent coking, reduce heat bias, and prevent boiler tail fuel re-combustion; closely monitor the boiler steam parameters, evaporation and water level, to prevent over-temperature, overpressure, water shortage and other accidents.

4. To ensure the oil fired boiler feed water quality, to reduce fouling and corrosion within the water wall tube, strengthen supervision over boiler water quality. At the time of installation and maintenance, should try to reduce the distance between the superheater tubes and wall while equal distance between the tubes.
