When the load on the gasifier decreases
Thread Content
Does the quenching air volume decrease after the load is reduced? It’s normal, right! When the load is reduced, the gas production decreases accordingly! The furnace pressure also decreased accordingly; 13FICA0008 is the value obtained through temperature-pressure compensation! When the gas production decreases, less quenching gas is discharged by the compressor; does this mean that the work done by the compressor changes and the current decreases as well? Please take a look and see if this understanding is correct!
Once the load is reduced, it’s certain that the gas production volume will be low, but the furnace pressure isn’t necessarily low either; furnace pressure is determined by the speed of the synthesis compressor in the downstream system. With reduced gas production and thus lower synthesis load, it’s possible to reduce the speed of the syngas compressor without a decrease in system pressure. The amount of cooling gas supplied can be adjusted; generally, it is related to the pressure in the vaporization furnace. As long as the system pressure remains constant, the speed of the cooling gas compressor can be increased to maintain the level of cooling gas, without an increase in the compressor’s power consumption.
If the gas production decreases and extreme cold is felt, the compressor power can be reduced.
Once the load is reduced, the gas production volume will certainly be low, and the furnace pressure will also drop momentarily. Although the furnace pressure is determined by the speed of the compressor in the rear system, the regulation of the rear system is generally somewhat delayed.
It shouldn’t be correct; the compression volume of the compressor is related to its speed and the opening degree of the outlet control valve. Of course, it’s also affected by temperature and pressure. However, the vaporization furnace only reduces its load without lowering the pressure. As a result, once the subsequent processes stabilize, there won’t be significant fluctuations in the pressure of the vaporization furnace. Meanwhile, the amount of quenching gas used operates in a closed loop system, and it isn’t directly related to the load of the vaporization furnace
