ZEMAG Combined Gasifier of Lump Coal and Fine Coal


Conclusions

结论(1) to utilize the coal resource mostly and have the ability to deal with

various issues including imbalance of lump and fine coals, waste water,

dusty tar, and so on.

最大程度地利用煤炭资源；能够处理块粉平衡、废水、含尘焦油等问题。

(2) to make the gasifier available to Lump coal and pulverized coal/

water coal slurry lump coal by self balance through different tuyeres

可以通过不同的喷嘴喷入粉煤或水煤浆的方式，自平衡气化块煤和粉煤或块煤和水煤浆。

How to get more tar from oil rich coal？(Oil content > 5%)

如何能够从富含油的煤中获得更多的焦油？(油含量>5%)

◦ Solutions to this Task:

解决上述问题：

1. Design with Increase in the height of coal bed

提高煤床层高度

2. Revamp the top of gasifier

改造气化炉上部

ZEMAG High-tar-yield Devolatilisation-gasification Combined Gasifier

Revamp the

top portion of

gasifier

改造气化上部

Increase the retention time

and improve the counter-

current heat exchange

增加干馏的停留时间和逆流换热效果

Increase the

bed height

增加床层高度

Change the gas distribution

and countercurrent heat

exchange into intermittent

heat exchange

改善气流分布，变逆流换热为间接换热

Revamp the top portion of gasifier to change

the gas produced in gasification and

combustion zones.

改造气化炉上部以改变气化区和燃烧区产生的气流分布The gas is separated into two streams: the

one goes up along the central chamber to the

hot gas outlet and the other goes through the

cold fuel bed then leaves from the cold gas

outlet.

气流分为两股：一股向上经过中央室，由高温粗煤气出口排出；另一股向上流经冷的燃料床层，然后由低温粗煤气出口排出。

Development of ZEMAG Slagging Gasification Technology


Conclusions

结论

For Solution 1: it can increase the tar/oil yield to 55-70%

percent to some extent.

方法1：能够一定程度上提高到煤含油量的55-70%；

For Solution 2： change the gas distribution, maintain the high

throughput of processed solid material and can reach higher

process thermal efficiency with tar/oil yield up to 80%.

方法2：改变气流分布，维持固体物料的处理能力，可以达到更高的热效率，焦油/油产率高达80%。
