The central cylinder is placed in the fuel cartridge combustion boiler, the boiler combustion due to higher temperatures, the material for the central cylinder should have good high temperature properties, so that in use will reduce the loss of the central cylinder. When the boiler combustion, in addition to be affected by temperature, it will also corrode other substances, let's look at a common boiler center tube material.
Oxidation of the steel corrosion stability refers to a gaseous medium at high temperature oxidation. It is an important condition of the workpiece to be durable operating under high temperature to ensure that the basic method of the high temperature oxidation resistant steels today improved alloying, add a sufficient amount of chromium, nickel, silicon, manganese and other alloying elements in the steel, the steel at high temperatures oxidation of the surface can generate a stable layer of dense Cr2O2 / SiO2 and Al2O3 in the oxide film. These oxide films can be firmly adhered on the surface of the metal, which can effectively protect the metal from oxidation and corrosion of the high temperature gas medium.
Some central tube boiler is made of steel as the main material made of, if not done in the use of conservation center tube, it will directly affect the normal use of the latter part of the boiler. When using the central cylinder, we should do regular quality inspection center of the cylinder, to detect faults, promptly replaced, reducing the impact on the boiler operation.
