Waste heat boiler is a kind of industrial equipment. Although the equipment is simple to operate, it also needs special attention in practical application. Shanghai Horizontal fuel oil steam generator So what should we pay attention to when it runs? Generally, when using waste heat boiler, we need to pay attention to prevent misfire. Due to the excessive output of the burner, the flame will disengage from the burner, resulting in incomplete combustion. A large amount of mixed gas in the furnace may cause explosion, and backfire should also be prevented. Due to the low output, the flame will retract into the burner, resulting in unstable flame flameout vertical Horizontal fuel oil steam generator how much If the combustible gas continues to enter the limit, it may cause explosion. After ignition, pay attention to adjust the combustion gas flow, stabilize the burner pressure, so that the flame can burn stably. In order to reduce the smoke from the chimney and pollute the environment, smoke suppression and dust removal devices should be installed.

The long-term use of gas-fired boilers will inevitably lead to problems of one kind or another. However, the working principle of gas-fired boiler is complex, and the price of gas-fired boiler is particularly high, so it is necessary to select high-quality gas-fired boiler manufacturers and companies with good after-sales service. Shanghai Horizontal fuel oil steam generator In addition, what should we do if the gas boiler fails? As the gas-fired boiler involves the construction of gas and lines, the professional installation personnel of the manufacturer must check the installation at home, and the professional personnel shall install it. Improper installation will bring a series of problems for future use. vertical Horizontal fuel oil steam generator how much The existing pipes and radiators in China need to be observed by professional engineers and installation personnel to determine whether they can continue to be used. If the service life is long, the heating system may scale more. It is generally recommended that the user replace it to obtain better heating effect.

The flue gas waste heat recovery device also has the following characteristics: 1. Energy saving. It uses new heat exchange fins and heat exchange elements to make heat exchange more fully, and the exhaust gas temperature can be reduced to 40 ℃~80 ℃; The boiler efficiency can be increased by 6~15%, and the condensate drainage structure can fully recover the latent heat in the flue gas, with remarkable energy-saving effect. Shanghai Horizontal fuel oil 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. 2. Beautiful. Due to the use of efficient heat exchange elements and reasonable structural configuration, this product has the characteristics of compact structure, small size, beautiful appearance, etc. vertical Horizontal fuel oil steam generator how much Durable. The heat exchange tube of the flue gas waste heat recovery device is made of stainless steel aluminum fins for efficient anti-corrosion. 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.

High heat exchange efficiency. The fusion rate at the contact is more than 95%, the contact thermal resistance is small, and the thermal conductivity is good. Low flow resistance. Shanghai Horizontal fuel oil steam generator Since H-shaped finned tubes are similar to square structures, after being assembled into heat exchangers, the tubes are divided into many small channels by fins, which has a certain uniform effect on the air flow. The air flow is similar to longitudinal downstream flow, and the air flow resistance is relatively small. However, spiral finned tubes have strong air flow disturbance, high turbulence, and large air flow resistance due to the directivity of the fins. Less ash. The flue gas contains fly ash, which is easy to deposit on the windward side and leeward side of the pipe bundle. The H-shaped fin tube bundle has the characteristics of uniform flow and downstream flow, so it is not easy to cause serious local ash deposition, and the fly ash can be taken away with the air flow in time. Therefore, compared with spiral finned tube heat exchanger, H-type finned tube heat exchanger has less ash deposition. vertical Horizontal fuel oil steam generator how much Small size and low weight. H-shaped finned tube has high area expansion rate, less ash deposition, and high heat transfer efficiency. When the heat transfer capacity is equal, the space occupied by the heat exchanger can be small. For reconstruction projects, the heat exchange area can be arranged as much as possible in the limited space to reduce the exhaust gas temperature, improve the waste heat recovery efficiency, or increase the maintenance space to facilitate maintenance.
