In daily life, pressure vessels are divided into those in contact with fire sources and those not in contact with fire sources. In fact, pressure vessels also need anti-corrosion in daily life. For the anti-corrosion of pressure vessels, we need to do the following. Kunming Horizontal gas steam generator First, check the structure of its equipment components, safety valves, bursting discs, emergency vent valves and other collective Yixing pressure tanks to see if there is any corrosion. Once corrosion occurs, measures should be taken in a timely manner. Anti rust paint should be painted before the equipment is used. After use, it should be cleaned in a timely manner to ensure the cleanliness of the equipment. vertical Horizontal gas steam generator how much Secondly, it is necessary to protect the safety device of the pressure vessel. The safety device is an important device of the pressure vessel. Good protection should be carried out. Good maintenance should be carried out before and after use. It is necessary to apply lubricating oil and antirust paint.
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. Kunming Horizontal 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. vertical Horizontal 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.
The waste heat boiler greatly improves the utilization rate of heat released by fuel combustion, so this kind of boiler saves energy; Fuel oil, gas and coal combustion generate high-temperature flue gas to release heat. The high-temperature flue gas first enters the furnace, then enters the waste heat recovery device of the front smoke box, then enters the pyrotechnic tube, and then enters the waste heat recovery device in the flue of the rear smoke box. The high-temperature flue gas turns into low-temperature flue gas and is discharged into the atmosphere through the chimney. Kunming Horizontal gas steam generator Conditions conducive to quick startup of waste heat boiler: (1) The waste heat boiler adopts forced circulation, which has the priority of quick startup. (2) The flue gas baffle is hydraulically controlled, which can be used to adjust the sky in principle. The flue gas flow into the boiler is reduced. (3) The adjustable guide vane at the inlet of gas turbine can not only adjust the flue gas flow of gas turbine, but also increase or decrease the exhaust gas temperature of gas turbine through the selection of IGV temperature control mode. (4) The steam turbine bypass is designed for the rated evaporation capacity of the boiler. (5) The welded bends and headers of each heating module of the boiler are in the boiler. (6) Similar boilers in other gas turbine power plants can not be reduced when starting, and can be used to adjust the main steam pressure of the boiler. Outside the wall, contact with high-temperature smoke is avoided. vertical Horizontal gas steam generator how much Operating experience of gas turbine load, such as simultaneous startup of gas turbine and waste heat boiler (flue gas damper fully open). Under the possibility of quick startup of waste heat boiler, the water level of steam drum and deaerator will lose control after the flue gas baffle is opened.
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. Kunming 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. vertical Horizontal gas steam generator how much 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.
