Why is oil fired watertube boilers whats the difference require fuel boiler galvanized galvanized I think we more or less have heard of, but you know why it needs to galvanize it? Burners of the boiler is a key component of the boiler, and the boiler which are matched to the selection, control and adjustment of combustion is very important. The role of the burner is a good fuel burning equipment organization of work. To thus the fuel is atomized into fine particles, while supplying the oxygen required for fuel combustion, so that the burner consists of two parts, a fuel supply device equipped with breathing apparatus. Computer control system is another major component of the oil-fired boiler, the equivalent of the human brain to achieve a variety of commands upload issued, if used properly, less hardware problem. Is subjected to high-temperature baking furnace, heat transfer, a desired output intermediate heat medium, its poor conditions, a large output, it determines the quality of life of the whole length of the boiler, the material selected to have greater resistance to resistance, good tensile strength, and good thermal conductivity. There are many customers will ask for galvanizing furnace, to do so will have the following advantages. First, zinc can extend the life of the boiler, the zinc is a very reactive metal, is extremely easily oxidized, but not as zinc oxide, iron oxide as a loose powder, but a dense skin layer, a zinc oxide layer which prevents internal further zinc oxide. When the galvanized steel sheet surface is damaged, the exposed surface of the inner iron of the time, since zinc is more reactive than iron, so according to the principle of chemical batteries, zinc iron oxide will first, thereby protecting the iron layer is not damaged. So the life of galvanized boilers will be extended. Second yellow prevent the boiler output water, affect water quality. Boiler pressure test will be at the factory, the welding quality inspection of the boiler, in this process there will be some residual moisture, the internal moisture comparison, be slightly oxidized. If the water quality in the area somewhat less, during use, the wall of the inner furnace wall and will be attached to a layer of scale, part of the original sheet is covered with rust, so it will not yellow water, if used in areas with good quality during use does not generate boiler scale, rust original sheet portion will not be covered, it will produce yellow water. Existence of things has two sides, good water quality chrysogenum area, but the life of the boiler does not produce poor water quality than the yellow water areas for much longer. Therefore, oil-fired boiler galvanized not only extend the life of the boiler, but also a great improvement in the quality of output.

How can I improve the performance of the steam watertube boilers whats the difference it? Any users want to buy their own steam boilers have a good performance, but there are some difficult users should be satisfied with the performance of the boiler. It is precisely because it does not meet the requirements in production, then how can we improve the performance of such devices it? First we need to have high-quality manufacturers in the production of boiler body. A boiler first need to have a better body. For now the boiler production industry, the production lines are also subject by the manufacturers, upstream manufacturers to supply parts production form.
