What is the carbon conversion rate of a Texaco gasifier? This post was last edited by shanxg on 2009-4-8 09:48 ]
Project Pressurized Luchi Texaco Shell Dry Coal Powdered Coal Raw Coal Processing Crushing - Screening and Grinding - Pulp and Grinding - Drying Raw Coal Ash Content Requirements Generally Unlimited Low Low Raw Coal Processing Fee Low High High Raw Coal Transportation Easy Easier Harder Gasification Pressure (MPa) 2-3, lower 2-6.5, higher 2-4, higher gasification temperature (℃) 900-1100, low 1300-1400, high 1400-1600, high coal input per furnace (t/d) 1000-1300, low 2000, high 2500, high oxygen consumption (M3/1000M3) 267-350, low 380-430, high 330-360, high carbon conversion rate (%) 88-95, low 96-98, high ≥99, high cold gas efficiency (%) 65-75, low 70-76, high 80-85, high total thermal efficiency (%) 80-90, low 90-95, high -98, high, rich in commercial operation experience, basically rich but not rich
I checked the relevant information and it shows that it is about 90%.
It should be around 90%, not too high, but if you consider char recycling, it can reach 99%
Texaco's general conversion rate is 96%, and four nozzles can reach 98%.
It is unlikely to be as low as 90%, otherwise there must be something wrong with the burner operation. I wonder if my friends on the 4th and 5th floors have done a carbon balance on the gasifier?
At present, the carbon conversion rate of Texaco furnaces is relatively high, generally above 96%, and four nozzles can reach above 98%.
Is there a calculation process for constant calculation of materials and heat?
It seems that the residual carbon content in Texaco residue is about 30%, and the carbon conversion rate is about 90 or more.
We are in a rather miserable situation here... There are two types of burners (GE and domestic). The carbon content of the ash in the two sets of furnaces is "10% and 15-20% respectively. Alas, the conversion rate is one" 96% and the other 92%.
The so-called Texaco gasification carbon conversion rate can reach 96-98%. These are theoretical data. In fact, it is good if it can reach 95. It is more reliable to say that it is above 90%.
This calculation is based on the calculation of coal slurry entering the furnace. Most conversion rates are above 95. Unless your load is very low and calculated based on the amount of coal in the belt, your conversion rate may not be very accurate because the error of the weighing machine, as well as the loss of transportation, pulping, and back grinding machines, are all included in it.
