By adjusting and controlling process parameters such as pressure, temperature, and water level within the conventional permitted range, and evaluating the stability and safety of various instruments, valves and other components, the safe and stable operation of the gas steam generator can be fully ensured. So what issues need to be paid attention to when a gas steam generator generates steam?
Because the water temperature of the gas steam generator continues to rise, the temperatures of the metal walls of the bubbles and evaporation heating surfaces gradually increase in real time. Gas steam generator is an energy conversion device. The energy input to the steam generator includes chemical energy in the fuel, electrical energy, thermal energy of high-temperature flue gas, etc. After being converted by the steam generator, steam is output.
The gas steam generator is equipped with a computer controller, and various functions are stored on the smart chip, completing the intelligent, automatic and intelligent control of the steam generator. Because of the thick wall thickness of the bubble, the key issue in the case of steam generator heating is thermal stress, so it is important to study the thermal expansion temperature and thermal stress of the bubble.
In addition, the overall thermal expansion must be considered, especially the tubes on the heating surface of the gas steam generator. Because of their thin walls and long length, the problem under heating is thermal expansion of the entire pair. The gas steam generator has the remarkable characteristics of environmental protection, energy saving, safety, fully automatic operation, and is very convenient to apply.
Because of its economical operation, gas steam generators are increasingly recognized by people. In addition, attention should be paid to its thermal stress to avoid damage caused by neglect. When the gas steam generator generates steam and heats pressure, a temperature difference occurs between the bubbles along the wall thickness and between the upper and lower walls.
When the inner wall temperature is greater than the outer wall temperature and the upper wall temperature is greater than the lower wall temperature, in order to avoid excessive thermal stress, the steam generator pressure must be slowly increased. When the gas steam generator is ignited and boosted, the steam parameters, water levels and working conditions of each part change dynamically. Therefore, in order to effectively avoid abnormal problems and other safety issues, technicians must be arranged to closely monitor changes in instructions for various instruments.
The higher the pressure and energy consumption of the gas steam generator, the higher the pressure of the corresponding steam equipment, pipelines and valves, which will lead to higher protection and maintenance requirements for the gas steam generator. During production and transportation, the proportion of heat dissipation and steam loss will also increase. The salinity of high-pressure steam increases as the air pressure increases. This kind of salt causes structural problems in the heating areas such as water-cooled wall pipes, flues, furnace pipes, etc., causing overheating, bubbling, and blockage. When obvious, it will cause safety problems such as pipe cracks.
