Product Introduction
Compared with the original atmospheric pressure gasification furnace, the pressurized circulating fluidized bed gasifier has low investment (10%-20% reduction), low operating cost (cost of each standard square gas is reduced by about 0.03 yuan), and high efficiency (gasification cold The gas can reach 80%) and the gas has high calorific value (gasification calorific value of pressurized air is up to 6.70MJ/Nm3 (1600kcal/Nm3)) and other advantages.
[Coal type requirements] Use 0-12 mm pulverized coal as raw materials, coal types include lignite, long flame coal, non-sticky bituminous coal, weakly sticky bituminous coal, etc.;
[Coal Quality Index] Volatile content of dry ash-free base: ≥25%; ash melting property: ash softening temperature ≥1100℃; reaction activity of raw coal to carbon dioxide: α%≥60% at 950℃; coke slag characteristics: ≤5;
Product Feature
Pressurized circulating fluidized bed gasifier
1.Wide fuel adaptability
2.Large load adjustment range
3.Short construction period
4.Stable and reliable operation
5.Large-scale gasifier. The single furnace capacity of atmospheric pressure gasification can reach up to 80,000 Nm3/h, and the pressure can reach up to 120,000 Nm3/h.
Product Advantage
The reaction temperature in the furnace is uniform, up to 1000°C, no tar and phenolic substances are produced, the cooling adopts indirect cooling, and the dry slag bag dust removal, no waste water is produced.
1. One Huangtai furnace with an effective gas output of 40,000 Nm3/h can replace 7 intermittent fixed-bed gasifiers;
2. The Action Plan for the Efficient Utilization of Coal in the Industrial Sector (2015-2020) recommends the use of circulating fluidized bed coal gasification as a reference technology for the clean and efficient utilization of coal in the industrial sector;
3. The original fixed-bed synthetic ammonia plant is transformed by the yellow furnace, and the cost of ammonia per ton is reduced by about 600 yuan.
Product Application
In the past few decades, we've done a lot of coal gasifier projects at home and abroad, receiving high evaluations from our customers.
