When the boiler is shut down, the temperature of the heat transfer oil can be reduced to below 70 ℃ before the hot oil pump is shut down. In case of sudden power failure, extinguish the fire immediately, and then implement the operating procedures. Otherwise, the furnace tube will be burned out and the loss will be large. According to the type of heat transfer oil boiler, heat transfer oil shall be reasonably selected to prevent overheating. Hebei Oil fired gas steam generator When purchasing unqualified heat transfer oil, do not save money or mix heat transfer oil indiscriminately. Otherwise, the consequences will be very serious. Prevent the oxidation of heat transfer oil. The strict heat transfer oil is more than 50 degrees in contact with the air, which will make the heat transfer oil crack. Its speed is amazing, and the consequences are relatively serious. After normal operation, the test crew needs to close the exhaust valve on the auxiliary exhaust pipe. After 6 months of use, the heat transfer oil must be sampled and tested according to the instructions. If problems are found, the heat transfer oil must be replaced immediately. small-scale Oil fired gas steam generator how much However, it should be noted that different types of heat transfer oil should not be mixed. The circulation speed of the heat transfer oil should not be less than 1.5m/s. Due to the excessive temperature difference between some entrances and exits, the original design requirements were destroyed, the heat transfer oil could not maintain the original circulation state, the boundary layer became thicker, and the thermal resistance became larger, making the furnace wall exceed the oil film temperature, leading to carbon deposition, cracking, polymerization, coking, and even burning through the furnace tube.

The hardness of water is mainly formed and expressed by calcium and magnesium, so cation exchange resin (water softener) is generally used to replace Ca2+and Mg2+(the main component forming scale) in the water. With the increase of Ca2+and Mg2+in the resin, the efficiency of the resin to remove Ca2+and Mg2+gradually decreases. Hebei Oil fired gas steam generator When the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated. The regeneration process is to wash the resin layer with salt water in the salt tank to replace the hardness ions on the resin. With the regeneration waste liquid discharged out of the tank, the resin will resume its softening and exchange function. small-scale Oil fired gas steam generator how much Because the hardness of water is mainly formed by calcium and magnesium and represents that the hardness of water is mainly formed by calcium and magnesium and represents the principle of sodium ion exchange softening treatment, which is to exchange the hardness components Ca2+and Mg2+in the water with the Na+in the resin by passing the raw water through the sodium cation exchange resin, so as to absorb Ca2+and Mg2+in the water and soften the water.

Energy saving. The waste heat boiler adopts new heat exchange fins and heat exchange elements, which enables full heat exchange. The boiler efficiency can be increased by 6~15%, and the condensate drainage structure can fully recover the latent heat in the flue gas. The energy-saving effect is remarkable. Hebei Oil fired gas steam generator Due to the special structure, the total pressure drop is small and the power consumption is small, that is, the smoke pressure drop is small and meets the system requirements. beautiful. Due to the use of efficient heat exchange elements and reasonable structural configuration, the waste heat boiler has the characteristics of compact structure, small size, beautiful appearance, etc. Durable. Heat exchange tubes of waste heat boiler facilities are made of stainless steel aluminum fins for corrosion prevention. small-scale Oil fired gas steam generator how much The thermal stress, anti-corrosion performance and strength are fully considered when the equipment is manufactured, which can ensure the safety, reliability and stability of the equipment, with a service life of more than 25 years.

Biomass boilers need green new energy. Compared with other boilers, biomass boilers have the following four major advantages: one boiler is multi-purpose, and can cook, boil water, and bathe while heating. Strong conversion system, low starting heat transfer temperature and fast heat transfer speed. Hebei Oil fired gas steam generator Low installation cost, safe heating: the equipment is universal, without changing the original heating equipment, and the pipes and radiators are universal. Water circulation is used to achieve a wide range of heating materials, which will never be exhausted. It can be taken everywhere (such as rice husks, corn stalks, rice stalks, wheat). Safety and environmental protection: low working pressure, cooking, water boiling, bathing, heating, etc., and it is also suitable for burning boilers, greenhouse heating Large area heating and small and medium-sized hotels can be used all year round without seasonal restrictions. small-scale Oil fired gas steam generator how much The reason why the ignition of biomass boiler is difficult is that the stable small fire signal cannot be established, which is caused by the failure of the small fire detector to detect the fire normally. The flame detector for small fire is ionization type flame detector, which requires a contact area with the flame, stable flame size, and gas pressure controlled within a strict range.
