Waste heat boiler is a kind of industrial equipment. Although the equipment is simple to operate, it also needs special attention in practical application. Jilin Horizontal gas 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 small-scale Horizontal gas steam generator factory 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 steam used in the steam generator of the hotel laundry is usually 0.4~0.6MPa saturated steam. The working temperature of steam is not very high. Jilin Horizontal gas steam generator The steam boiler of the hotel requires high steam efficiency due to operating costs, so it can save operating costs. The area of the hotel is relatively limited, so the steam boiler with small floor area must be selected. In order to control the investment cost and heat loss of the steam pipe, the steam boiler is usually placed on the side of the laundry room. small-scale Horizontal gas steam generator factory The steam equipment in the hotel laundry room can only be turned on when washing, not when washing. Therefore, the steam generator is required to start steam production quickly. Laundry equipment is sometimes opened a lot and sometimes less, so the steam boiler is required to adjust the steam volume within the specified range.

Waste heat boilers are widely used in high energy consumption industries. There are two common types of waste heat boilers: one is used to recover the exhaust gas emitted by ordinary boilers, such as fuel fired and gas-fired boilers, biomass fired boilers, etc. The temperature of the exhaust gas from ordinary boilers is about 600 ℃, which is not too high, Therefore, the requirements for waste heat recovery boiler are relatively low. Jilin Horizontal gas steam generator The other is industrial waste heat recovery boiler, such as building materials industry, chemical industry, steel making industry, etc. The temperature of waste gas and waste heat in these industries is high, and the recovery and utilization are also quite valuable. small-scale Horizontal gas steam generator factory Henan Yuji Boiler Vessel Manufacturing Co., Ltd., founded in 2005, is located at No. 8, Jizhong Road, Xiaoji Town, Xinxiang County, Henan Province. It is a comprehensive enterprise of boiler and pressure vessel, mainly engaged in the manufacturing of boilers and pressure vessels, with technological innovation as the core, integrating the design, manufacturing, sales, installation, transformation and maintenance of boilers and pressure vessels.

The furnace liner is the combustion chamber of the horizontal gas-fired heat transfer oil furnace. The burner nozzle is placed in the front of the furnace liner, and the high-temperature flue gas generated by combustion extends to the rear, leaving the furnace liner and returning to the space. Generally, the number of times of returning is not more than four, and the common one is the three return heat conduction oil furnace. Jilin Horizontal gas steam generator This type of heat transfer oil furnace can be divided into dry back type heat transfer oil furnace and full wet back type heat transfer oil furnace according to the structure of the flue gas reentry space at the rear of the furnace. The flue gas reentry space of the dry back heat conduction oil furnace is enclosed by refractory materials; The flue gas reentry space of the full wet back type heat conduction oil furnace is composed of a recuperative chamber immersed in water. In addition, there is a central regenerative heat conduction oil furnace: that is, the back wall of the furnace liner is sealed inside the boiler shell, and the flue gas is turned back to the front from the inner wall around the furnace liner after encountering. This type of heat transfer oil furnace can also be regarded as a full wet back heat transfer oil furnace. small-scale Horizontal gas steam generator factory Although the dry back heat transfer oil furnace is simple in structure, the refractory material at the rear of the furnace liner is easily damaged, and the rear tube plate is often directly washed by high temperature flue gas. The temperature difference is large, so the dry back heat transfer oil furnace is obsolete. At present, few manufacturers produce it; Although the full wet back heat conduction oil furnace has a complex structure, it avoids the problem of flue gas sealing in the reentry space and is suitable for micro positive pressure combustion.

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. Jilin Horizontal 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 Horizontal gas steam generator factory 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.
