Steam generator superheated steam temperature changes in the factors affecting the main flue gas temperature and flow rate, saturated steam temperature and flow rate, desuperheated water temperature and other elements of change.

1, the steam generator's furnace outlet flue gas temperature and flow rate of the impact: when the flue gas temperature and flow rate will lead to greater convective heat transfer of the superheater, so that the superheater heat absorption increases, so the steam temperature will rise.

Affect the flue gas temperature and flow rate of the degree of many reasons, such as the adjustment of the number of fuels in the furnace, the strength of combustion, the nature of the fuel itself (i.e., the percentage of coal contained in the various components of the change), the adjustment of the amount of excess air, the change in the mode of operation of the combustion injector, the height of the water temperature of the steam generator, the degree of cleanliness of the heated surface and so on, as long as any one of these factors appeared to be a significant change, there will be a variety of chain reactions. There will be a variety of chain reaction, but also directly related to the flue gas temperature and flow rate changes.

2, the steam generator superheater inlet saturated steam temperature and flow rate impact: when the saturated steam temperature is low, the steam flow rate becomes larger, the need for superheater to bring more heat. In this case will inevitably cause changes in the superheater operating temperature, which directly affects the temperature of superheated steam.

The factors affecting the saturated steam temperature and flow size are mainly the changes in the load of the steam generator, i.e., the adjustment of the steam production and the pressure in the pot. Changes in the level of water in the pot can also cause changes in steam humidity, and changes in the inlet temperature of the steam generator and combustion conditions can also cause changes in the amount of steam produced.
