A:The steam quality of the steam generator is mixed, many are good, many are questionable, and the result will affect the overall application. What are the common quality factors of steam generators? This common sense will be introduced in detail here.
In the steam generator, there are many bubbles in the water. As the blisters come and go, it breaks down into many small, scattered droplets. When the furnace water concentration is low, the water level, load and pressure of the furnace generally remain stable, and such water droplets are not simply carried away by the steam. Because of the weight of the water droplets themselves, these will return to the water when they are scattered at the same height.
When the steam generator continues to evaporate and concentrate, the brine concentration of the pot water will gradually increase. The surface tension of the pot water also continues to increase, and a large foam layer will exist on the surface of the steam generator. As the concentration of the tank water increases, the thickness of the bubbles will also increase. The effective space of the steam drum is reduced, and when the bubbles are broken, the water droplets are completed according to the upward movement. When the foam collapses severely, the steam and water rise together to produce a large amount of water.
When the water level of the steam generator is too large, the steam space of the steam drum will decrease, the steam volume according to the corresponding unit weight will also increase, the steam flow rate will increase, and the free water droplets will shrink, which may cause the water droplets to steam smoothly and reduce the steam capacity The mass, water level also forms steam which in turn brings water in an instant.
If the load of the steam generator increases, i.e. the amount of steam per unit steam space in one hour increases, the lifting speed of the steam generator increases to generate satisfactory heat, and highly scattered water droplets will form on the water surface, especially when the load shakes or When overloaded, even if the salt concentration of the pot water is not high, the soda can have serious consequences.
