Regarding the issue of flue draft
Thread Content
Dear teachers: During the quality certification process, the inspectors requested that the suction force in the flue ducts be indicated as a negative value, along with its magnitude. Is this really necessary?
That must be carried out as ordered; otherwise, don’t proceed with the certification. During the Cultural Revolution, there was a saying: „Those who understand must carry out the orders, those who don’t understand must still carry them out, and understanding will come through execution.“ ”This phrase is still quite useful for understanding certain things these days. Either ask the mentor for guidance or carry it out, since they represent the standard. There might be some things you don’t yet understand, and it may not yet be possible to get guidance from others; this is when it’s time to take action.
If the indicator is named “flue suction,” it will have a positive value; if it represents flue pressure, a negative sign must be added in front of the value
