The thermal cracking reaction of the steam fired boiler in south africa introduces that the boiler should be carefully introspection, waterproof, acid, alkali and low boiling point leakage into the application system, the system should be equipped with filtration installation to avoid all kinds of debris entering, enveloping the purity of oil. It is easy to be oxidized in the process of heating, and the acid value of oil increases and the rate of change is large at high temperature. The kinematic viscosity of the boiler increases gradually, which is due to the thermal cracking and condensation reaction of the components at high temperature. The pyrolysis results lead to the formation of small molecular compounds and decrease their viscosity; when the operating temperature is 300? 400 ℃, the pyrolysis occurs easily, and carbon deposition occurs in the inner wall of the pipe and equipment, which results in the heat accumulation of the pipeline affecting the heat transfer. Efficiency, poor fluidity of oxidized oil slime in pipeline, accelerated aging failure of conductive oil, local overheating of furnace body and pipeline, endangering mechanical strength and endangering personal safety.
d. increase maintenance costs steam fired boiler in south africa or heating the inner wall of the tube after the knot has the scale, very difficult to remove, especially due to the heating furnace tube or rupture, corrosion and other damage caused by scale, not only damaged the equipment, but also spend a lot of manpower and material resources to overhaul , resulting in increased maintenance costs.
