Each production, has its own multiple indicators, for conducting oil products today we want to talk about, too, in order to further enhance the understanding of its users, small to explain its several indicators are as follows: 1, HTF sulfur content: the sulfur content of refined HTF HTF and the depth of the printing industry professionals oil furnace, oil if the sulfur content is high, the actual production and use of the machine may cause corrosion skid coal-fired thermal oil heaters, so Standard sulfur content should not be more than 0.2%. 2, oil carbon residue, ash: carbon residue and ash is a reflection of the depth of thermal oil refining indicators. Carbon residue and a high ash coal-fired thermal oil chain oil furnace, high polycyclic aromatic ingredients, such as heavy, oil darker, poor thermal stability. 3, oil density: HTF HTF density is the reaction to form the index, and the heat transfer performance related. For related products have user applications may be understood that in order to achieve better effect, we would need to pay particular attention to their use of the process for conducting oil use, too, at elevated temperatures (about 80 ℃ time), and under the influence of oxygen, metals and other environmental factors, will gradually oxidative deterioration. The size and use of anti-oxidation stability also conditions such as temperature, oxygen pressure in contact with air, and the length are closely related. Therefore, the use of HTF (especially when heated above remind 80 ℃) To block the contact surface and air. Specific can do, that is, after conducting oil off water, emptying valve must be closed. In order to further enhance the user's understanding of its HTF professionals have their characteristics are summarized as follows: 1, non-toxic, tasteless, environmental pollution thermal oil heaters, energy-saving, save fuel, no corrosion on the equipment. 2, moderate viscosity, easy to coke, high thermal efficiency, high flash point, high initial boiling point, low pour point, the use of safety. 3, can be run at a lower pressure, higher operating temperature, reduces the working pressure line and the boiler. 4, this oil heating quickly, using high temperature, good thermal stability, long life, low voltage operation, safe, reliable and easy to operate. 5, using the North deep refined base oil, heat transfer oil than the same industry also has a high flash point, low temperature water efficient features.
