Pulverized coal boilers and pulverized coal-fired boilers, are they the same concept? What exactly does the flue gas flow rate of boilers refer to? Also, why is the phosphate radical in boiler water controlled between 5 and 15? In addition, there are some other questions related to boilers. These all involve important knowledge points of boilers. Therefore, specific answers will be given immediately below to make everyone clear.
1.Pulverized coal boilers and pulverized coal-fired boilers, are they the same concept?
Pulverized coal boilers and pulverized coal-fired boilers are the same concept. Because the fuel for both is pulverized coal. In this type of boiler, its main components include the furnace, burners, and ignition devices, etc. These are all indispensable components.
2.What exactly does the flue gas flow rate of boilers refer to?
Specifically speaking, the flue gas flow rate of boilers refers to the amount of flue gas produced by the boiler per hour. It can also be said to be the amount of waste gas produced during the combustion of the boiler. Its unit is Nm³/h, which is standard cubic meters per hour. Therefore, everyone should not make a mistake regarding their unit.
3.If there is an operating floor in the boiler, then is this type of boiler a large one?
The answer to this question is affirmative. If the boiler has an operating floor, then usually, it is a large boiler in a power plant and is of the suspended type. Its boiler room has a large frame mainly used to bear the weight of the boiler.
4. Why is the phosphate radical in boiler water controlled between 5 and 15?
If the phosphate radical in the boiler water is below 5, it cannot effectively play the role of anti-scaling. If it is above 15, it will affect the pH value of the boiler water, thereby causing various problems. Therefore, its value should be controlled within the range of 5-15. Moreover, it can also control the pH value of the boiler water well and achieve a good anti-scaling effect.
