Anonymous users2024-02-07Summary. The formula for calculating the flue gas volume of 116MW hot water circulating fluidized bed boiler is: flue gas volume (m3 h) = 116MW (flue gas temperature ( ) flue gas specific heat capacity (kj m3·k)).
According to different flue gas temperature and flue gas specific heat capacity, the flue gas volume will also be different. For example, when the flue gas temperature is 150 and the specific heat capacity of the flue gas is 116 MW, the flue gas volume of a 116 MW hot water circulating fluidized bed boiler is: 116 MW (150 *.

According to different flue gas temperature and flue gas specific heat capacity, the flue gas volume will also be different.
For example, when the flue gas temperature is 150 and the specific heat capacity of the flue gas is 116 MW, the flue gas volume of a 116 MW hot water circulating flow trapped bed boiler is: 116 MW (150 *.
Fellow, I really didn't understand, I can be more specific.
The flue gas volume of 116MW hot water circulating fluidized bed boiler is generally about 1300m3 h. Reasons for the problem:1
The flue gas volume of hot water circulating fluidized bed boiler is affected by the combustion conditions, such as fuel type, fuel composition, fuel calorific value, air ratio, combustion temperature, etc., if the combustion conditions are unreasonable, it will affect the flue gas volume. 2.The flue gas volume of the hot water circulating fluidized bed boiler is affected by the chimney, such as the height of the chimney, the inner diameter of the chimney, the baffle of the chimney, etc., if the parameters of the chimney are unreasonable, it will also affect the amount of flue gas in Qingyan.
Workaround:1Reasonably adjust the combustion conditions to make the combustion conditions meet the requirements to ensure the normal occurrence of flue gas volume.
2.Reasonably adjust the parameters of the chimney to make the parameters of the chimney meet the requirements to ensure the normal occurrence of flue gas volume. Personal Tips:
When running the hot water positive bridge circulating fluidized bed boiler, attention should be paid to the reasonable adjustment of combustion conditions and chimney parameters to ensure the normal occurrence of flue gas volume.

Anonymous users2024-02-06Summary. Dear, glad to answer for you! Circulating fluidized bed boiler boiling pressure refers to:
It is a direct parameter basis for reflecting the power working conditions in the furnace. Abnormal combustion in the furnace, changes in the supply of wind and coal, abnormal power equipment, changes in external loads and leakage on the steam side, any change in either side will cause the furnace outlet pressure to change.
Dear, glad to answer for you! The boiling pressure of circulating fluidized bed boiler refers to a direct parameter basis that reflects the power conditions in the furnace.
Abnormal combustion in the furnace, changes in the supply of wind coal or abnormal power equipment, changes in external loads and leakage on the steam side, any change will change the pressure of the furnace shed chamber outlet.
Dear, the expansion content is as follows: seep the shed dry oh <>
How to judge the quality of the boiler temperature field is as follows: only when the thermal balance of the combustion chamber is reached, there is an ideal temperature field in the furnace. The temperature difference in the combustion chamber of the circulating fluidized bed boiler is 20 longitudinally and transversely, and the maximum temperature is not more than 50.
Each part of the furnace can ensure that the designed heat release coefficient is realized, and all kinds of heat can absorb the required enough heat, so as to achieve the heat balance of each part and ensure the output of the boiler.

Anonymous users2024-02-05Summary. Hello dear Not only fluidized bed boilers, modern boilers have screen superheaters.
The so-called superheater is to further heat the saturated steam to form superheated steam. The screen superheater is only a form of arrangement of the superheater, and the screen superheater is to suspend the whole combination of superheater tubes above the boiler near the outlet (flame angle), mainly absorbing convection and radiant heat.
What is the concept of circulating fluidized bed boiler superheater.
Hello, I have seen your question and am sorting out the answer, please wait a while Hello Dear Not only fluidized bed boilers, but modern boilers have screen shouts or superheaters. The so-called superheater is to further heat the saturated steam to form a superheated mass to vaporize the steam. The screen superheater is only a form of arrangement of the superheater, and the screen superheater is to suspend the whole combination of superheater tubes above the boiler near the outlet (flame angle), mainly absorbing convection and radiant heat.
Hurry up. Hello dear The steam that enters the steam turbine to do work must be steam with a certain amount of superheat. What comes out of the boiler and furnace steam drum is dry drum and steam, which enters the superheater and is further heated to increase the superheat to become a new steam that meets the requirements.
Hello dear please how else can I help you.

The impact of too much or too little return ash on the boiler of circulating fluidized bed boiler dear, hello. The concept of circulating ash volume can be said to be the material in the external circulation of the circulating fluidized bed, or it can be said to be the amount of return material collected by the cyclone. About 50% of the fuel in the dense phase zone of the circulating fluidized bed is burned, releasing heat, which is used to heat fuel and air, and most of the remaining heat must be taken away by the circulating family as a material to maintain stability. >>>More
