1. The furnace pressure shall be measured by "t" or tubular pressure sensor specified in GB / T 9978.1. 

　　2.測量儀器的精度為±2.0pa。 　

　 2. The accuracy of the measuring instrument is ± 2.0pa. 

　　3.爐內(nèi)壓力每1min記錄一次，記錄設(shè)備的精度為1s。 

　　3. Record the pressure in the furnace once every 1min, and the accuracy of the recording equipment is 1s. 

　　4.壓力傳感器不應(yīng)放置在受火焰沖擊的地方或煙氣排放通道內(nèi)。當(dāng)壓力通過爐壁到達爐外，到達爐內(nèi)時，即爐內(nèi)壓力與爐外壓力相對于同一高度時，應(yīng)處于同一水平面上。當(dāng)使用“T”壓力傳感器時，“T”支路應(yīng)水平。 　

　4. The pressure sensor shall not be placed in the place impacted by the flame or in the flue gas discharge channel. When the pressure reaches the outside of the furnace through the furnace wall and reaches the inside of the furnace, that is, when the pressure in the furnace and the pressure outside the furnace are relative to the same height, they should be on the same horizontal plane. When using the "t" pressure sensor, the "t" branch should be horizontal. 　

　5.少應(yīng)使用3個壓力傳感器。一個放置在理論地面100毫米范圍內(nèi)，一個放置在門或窗簾高度三分之二的100毫米范圍內(nèi)，一個放置在門或窗簾頂部100毫米范圍內(nèi)。 

　　5. At least 3 pressure sensors shall be used. One is placed within 100 mm of the theoretical floor, one is placed within 100 mm of two-thirds of the height of the door or curtain, and one is placed within 100 mm of the top of the door or curtain.
