13PZHH0065 indicates that the pressure in the gasification furnace is positive, while the pressure in the A1 annular space is negative; this is what I have seen others say. In my understanding, the pressure in the A1 annular space should be positive, while the pressure in the gasification furnace should be negative. This is because if the pressure in the gasification furnace is higher than that in the annular space, syngas will escape. The annular space is filled with medium-pressure nitrogen at 5.2 Mpa. This is just my humble opinion; I’m not sure if it’s correct I would appreciate guidance from all of you. This post was last edited by shanxg on 2009-3-10 at 13:07.]
Others might have such an idea without taking into account the pressure generated during slag quenching and the role of the balance holes. SGSI requested last year that P0065 be changed to two-way measurement, with PZHH taking an ABS value; therefore, further debate is pointless.:
