How to choose oil-fired solve for boiler thickness with strong integration of countries on the environment, coal-fired boilers have been gradually phased out, replaced by a new generation of oil-fired boiler, we said what issues should be considered when selecting it do? Today small FYI for everyone finishing five points. 1 From the conditions of use. If the system is used in a liquid phase, generally should be selected higher than the boiling temperature of the thermal oil, because the higher boiling point, low vapor pressure which the motion, easy to use; if it is used under vapor phase conditions, should be selected in the appropriate at use temperature, then the vapor pressure in the range of 0.098 ~ 0.294MPa the HTF (1 ~ 3kgf / cm), as a low melting biphenyl diphenyl ether mixture plus HTF. 2 from the viewpoint of temperature. Select the appropriate temperature according to the HTF. If the temperature at 350 ~ 400 ℃, biphenyl and diphenyl ether should be used in a low-melting mixed conducting oil; temperature at 300 ~ 350 ℃ should be considered when selecting alkylbenzene type, dibenzyltoluene or hydrogenated terphenyl type HTF; temperature at 250 ~ 300 ℃, can consider selecting Kenai alkoxy, benzyl toluene, and benzene conducting oil; 250 deg.] C or less if used, is selected relatively low price of mineral conducting oil. 3 from the viewpoint of equipment and system conditions. As used in the long-term continuous operation of the system, must use a high thermal stability HTF; when used in a batch-type operation system, the thermal stability requirements can be relaxed some equipment during the outage, it may be considered by warming maintaining respective temperatures; if used in the device system relating to food processing, consider use non-toxic or low toxicity and high safety of products, such as silicone, fluorine and the like; heating, cooling processes use the same thermally oil, due to the selected temperature range broader HTF. 4 from the use of regional conditions and requirements to consider. If used in cold northern areas, should choose low-temperature fluidity and good thermal oil, in order to start the device; Jin Yong in place strict requirements on dangerous goods, should be considered the choice of security is good, non-flammable fluorocarbon products . 5 from the standpoint of economic efficiency. Both Wumart but also cheap and affordable to, to reduce costs. Above is the sort of small series for everyone all the time in the selection of oil-fired boilers should refer to the points I hope for your help.
Because of strong stainless steel 316L corrosion resistance (reinforced anti-corrosion surface), 316L stainless steel is widely used in military submarines, underwater robots, as well as Rolex diving watch, apple luxury watches and other civilian aspects. Stainless steel, molybdenum and titanium (316Ti) an anti-corrosion stainless steel capacity of about 316L 10 times, in particular between its superior resistance to intergranular corrosion, the main heat exchanger condensing solve for boiler thickness is the production of fine material, generally used only for special manufacture of high-end large-scale industrial boilers working under harsh environments and situations, such as a dedicated boiler large reservoirs, nuclear power plants use. This design is a single tube, large diameter, foot traffic and difficult to scale. Even the inner wall scaling phenomenon, not prone to clogging. It does not appear as clogging parallel circumstances do not report the failure occurred. Such as the occurrence of flow was significantly smaller, because the boiler will be cleaned and over-temperature alarm signals, to ensure that the plug fouling can be cleared up, maintenance and repair is of a design. In the current domestic water quality, there is no need to force adding inhibitors.
