1. 燃气热风炉使用条件。若在液相系统中使用,一般应选择沸点高于使用温度的燃油,因为沸点越高,其运动中蒸汽压越低,使用起来方便;若在气相条件下使用,应选择在合适的使用温度下,蒸汽压在0.0980.294MPa(1~3kgf/cm)范围内的燃油,如联苯加联苯醚低熔混合燃油。
1. Operation conditions of gas hot blast stove. If used in liquid phase system, fuel with boiling point higher than service temperature should be generally selected, because the higher the boiling point, the lower the vapor pressure in motion, and it is convenient to use; if used in gas phase condition, fuel with vapor pressure in the range of 0.0980.294 MPa (1-3 kgf/cm), such as biphenyl and diphenyl ether, should be selected at suitable service temperature. Low melting mixed fuel.
2. 燃气热风炉使用温度。根据使用温度选择合适的燃油。如果使用温度在350~400℃时,应选用联苯与联苯醚低熔混合型燃油;使用温度在300~350℃时应考虑选择烷基苯型、二苄基甲苯或氢化三联苯型燃油;使用温度在250~300℃时,可考虑选择烷基奈、苄基甲苯及烷基苯型燃油;如果在250℃以下使用,则选择价格相对较低的矿物型燃油。
2. Use temperature of gas hot blast stove. Choose the appropriate fuel according to the use temperature. If the service temperature is 350-400 C, the low melting fuel of biphenyl and diphenyl ether should be selected; when the service temperature is 300-350 C, the fuel of alkyl benzene, dibenzyl toluene or hydrogenated terphenyl should be considered; when the service temperature is 250-300 C, alkyl naphthalene, benzyl toluene and alkyl benzene should be considered; if the service temperature is 250-300 C, the fuel of alkyl naphthalene, benzyl toluene and alkyl benzene should be selected. For the next use, the mineral fuel with relatively low price is selected.
3. 燃气热风炉设备及系统条件。如在长期连续运转的系统中使用,必须选用热稳定性高的燃油;在间歇式运转系统中使用时,对热稳定性的要求可放宽一些,在设备停运期间,可考虑通过加温保持相应的温度;如果在与食品加工有关的设备系统中使用,则应考虑选用无毒或毒性小、安全性高的产品,如有机硅、氟素等;如加热、冷却过程使用同一种燃油,因选择使用温度范围较宽泛的燃油。
3. Equipment and system conditions of gas hot blast stove. If it is used in long-term continuous operation system, the fuel with high thermal stability must be selected; when it is used in intermittent operation system, the requirement of thermal stability can be relaxed a little, and during the outage of equipment, the corresponding temperature can be maintained by heating; if it is used in equipment system related to food processing, it should be considered. Select non-toxic or low toxicity, high safety products, such as silicone, fluorine, etc., such as heating and cooling process using the same fuel, because the choice of fuel with a wide temperature range.
4. 使用地区的条件和要求。如果在北方冰冷地区使用,应选择低温流动性好的热风炉,以便于设备的启动;在对危险物品有严格金庸要求的场所使用,则应考虑选用安全性好,不易燃的氟素类产品。
4. Conditions and requirements of the use area. If it is used in cold areas in the north, the hot blast stove with good low temperature fluidity should be selected to facilitate the start-up of the equipment; if it is used in places with strict Jinyong requirements for dangerous goods, the fluorine products with good safety and non-flammability should be considered.
5. 燃气热风炉经济效益方面。既要物美又要价廉,要经济适用,以降低成本。
5. Economic benefits of gas hot blast stove. It should be both good in quality and low in price, economical and applicable in order to reduce costs.
