According to the information available, the maximum feeding capacity for these three types of gas furnaces is 2000 t/d. I would like to ask experts: what is their maximum gas production rate in cubic meters per hour? How is this calculated?
Brief answer: First, it is somewhat difficult to answer this question, mainly due to the following reasons: 1. There are no GSP boilers with a coal feeding rate of 2000 t/d in operation yet, so there is a lack of data from actual industrial operations. 2. 2000 t/d is merely a conceptual figure; in practice, for boilers with the same coal feeding capacity of 2000 t/d, different companies require different maximum coal feeding amounts depending on the type of coal used, and some contracts are established based on 2200 t/d. 3. Different types of coal also affect the output of the furnace. II. Under normal circumstances, since the gas composition varies significantly among different furnaces, it is not appropriate to compare the total gas production of these furnaces; instead, the basis for comparison is usually the amount of useful gas produced by each individual furnace (CO+H2). III. Here, as a general rule, the coal consumption per unit of gas produced (i.e., the amount of coal required to produce 1000 Nm3 of CO+H2) is used as the basis for calculation. All calculations are based on a coal feeding rate of 2000 t/day (83.3 t/h). The amounts of useful gas (CO+H2) produced and the total gas volume are as follows: 1. SHELL: Coal consumption per 1000 Nm3 of CO+H2 is around 520 kg; the amount of useful gas (CO+H2) produced is 160,256 Nm3/h. Useful gas accounts for approximately 91% of the total gas volume, so the total gas volume is 176,106 Nm3/h. 2、GE: Compared to coal, the fuel consumption is ~550 kg/1000 Nm3 of effective gas (CO+H2). The amount of effective gas is 151,455 Nm3/h, and this represents ~78% of the total gas volume; therefore, the total gas volume is 194,173 Nm3/h. 3. GSP: Coal consumption of ~520 kg/1000 Nm3 (CO+H2) (Note: provided by the technology owner; lacks support from industrial operation data), similar to SHELL. It should be noted that the calculations and data mentioned above are for reference only. The technical parameters vary when the same gasification technology is used in different installations, and the values related to coal consumption and the proportion of useful gases in the syngas also differ significantly depending on the type of coal used. Generally speaking, for the same amount of coal fed in, dry coal powder gasification produces 6-10% more useful gas than coal slurry gasification.

Does GE’s effective gas energy account for ~87% of all gases?
The effective gas from GE should account for approximately 78% of all gases; the original value of ~87% was a mistake, and the calculations have been corrected. Please accept our apologies.
