Please tell me the difference between the waste boiler process and the cold shock process of the gasifier.

1. There are many posts on this topic in the forum. You can search and view them. 2. The main difference between the two is the different post-processing methods for gas.: ·The waste boiler process uses a waste heat boiler to recover the sensible heat of high-temperature gas, and produces high-pressure (or medium-pressure) steam as a by-product. Its main feature is high heat utilization efficiency, represented by SHELL coal gasification. The main disadvantage is that the investment is high, and it is suitable for power generation or processes that require a large amount of steam. ·The quenching process directly uses quenching water to cool high-temperature gas, which represents GE coal-water slurry. Its main advantages are low investment and reliable operation. The disadvantage is that the heat utilization effect is poor, and it is suitable for the process of producing chemical products.

The thermal efficiency and effective energy efficiency calculation data of the waste pot, quenching and waste pot quenching process are as follows:: Process Thermal Efficiency % Effective Energy Efficiency % Remarks Chill 93.83 89.24 Waste boiler chill 96.00 91.01 4.0MPa steam Waste boiler 95.96 91.74 4.0MPa steam 95.96 92.67 10.0MPa steam process There is no good or bad. The key depends on what the synthesis gas is used for, and the process is selected according to the downstream purpose. This post was last edited by purpleghj on 2007-12-10 09:48 ]
