Why should I adjust the water level of the industrial gas steam boiler? In general, this is to maintain the stability of the water level of the steam drum (drum) of the industrial gas steam boiler, and the step of water level adjustment is:
The main results are as follows: (1) in order to control the water level well, the water level must be carefully monitored, in principle, the primary water level meter shall prevail, and the electric contact water level meter shall be taken as the main monitoring meter. Keep the local water level meter clear and accurate. If the water level meter has no slight sloshing or the mica sheet is not clear, the water level meter should be flushed immediately, and the change of the water level of the industrial gas steam boiler should be accurately judged by comparing each water level meter regularly.
(2) to monitor the main data such as steam flow, feed water flow, drum pressure and feed water pressure at any time, and to find out the cause immediately and deal with it in a timely manner when it is found to be abnormal;
(3) if the water level exceeds 50, the small water supply regulating door should be closed to reduce the intake. If the water level continues to rise to 75, the accident discharge door should be opened to the normal water level, and the cause should be found out.
Calculation of flue Gas diameter of Industrial Gas Steam Boiler
Calculation of flue Gas diameter of Industrial Gas Steam Boiler
Formula for calculating the inner diameter of the exit of the chimney; D = NV/3600*0.785*U, in which the inner diameter of the outlet of the D-chimney is in meters, the root number (all the subsequent mathematical formulas are within the root number), and the inner diameter of the outlet diameter of the chimney is in meters. N-the hourly steam volume of all industrial gas steam boilers for which smoke is discharged by this chimney in tons per hour, and V-produces an estimated ton of steam per hour in cubic units. The flue gas velocity at the exit of the U-chimney is in meters per second. Note: U value in mechanical ventilation should be 12 �� 20 m / s, at micro positive pressure Run the furnace at 10: 15 m / s.
Note that the relevant calculation of boiler drum needs to be in accordance with the standard; ambient air quality standard GWPB3-, industrial gas steam boiler air pollutant emission standard. In addition, the resistance of the chimney should be taken into account when selecting the pressure head of the induced draft fan.
