Product Description
[Introduction] Oxygen-enriched gas users (30% ~ 90%) have higher heating value requirements, and users who need to modify the traditional fixed-bed gasification to produce synthetic ammonia gas head, the heating value can reach 2000kcal / Nm3;
[Coal requirements]: 0 ~ 12mm pulverized coal, coke, etc., not limited by the melting point of coal ash
[Gasifier]: oxygen-enriched + water vapor
[Reliability]: No rotating parts, can run continuously for more than 400 days
[Pressure range]: 0 ~ 50kPaG
Applicable scope of different gases
| Gasification type | Scope of application | remarks |
