焦煤预处理
戴尔塔焦煤预处理工艺基于其独有的高温流化床干燥技术，并借鉴新日铁的经验和教训而开发的领先于新日铁的焦煤预处理工艺。
戴尔塔焦煤预处理工艺仅对炼焦过程中易产生粉尘的超细煤进行造粒，将需要造粒的超细煤比例降低至焦煤总量的10%；超细煤造粒工艺采用水溶性粘结剂或无粘结剂造粒工艺；焦煤预热温度不超过220℃，预热后的焦煤运输和储存仍可利用现有的焦化厂设备（皮带输送机、煤塔和装料车），而无需采用密相气力输送。

Coking Coal Pretreatment
The development of Delta coking coal pretreatment process is based on Delta's proprietary high-temperature fluidized bed drying technology and draws on Nippon Steel's experience.
Delta process only briquet the ultra-fine coal (about 10% of the coking coal amount) that is prone to cause dust problems during the charging process; ultrafine coal briquetting can be water-soluble binders or binderless,

低阶煤热解
低阶煤热解将低阶煤通过干燥、预热和热解转化为三种形态（三种品质）：气体（热解气）、液体（煤焦油）和固体（半焦）。热解气、煤焦油和半焦进一步转化为油、气、电、热能和有机化工产品。
戴尔塔低阶煤热解工艺基于戴尔塔独特的高温流化床干燥技术及其在间接热交换褐煤垂直移动床干燥机领域的经验而开发。该工艺具有以下优势：热解气中粉尘含量极低（煤焦油品质最佳）；精确控制热解温度，最大程度提高煤焦油产量；单套装置产能高；工艺成本和投资低。

Low-Rank Coal Pyrolysis
The LRC pyrolysis process converts low-rank coal into three forms (three qualities) through drying, preheating, and pyrolysis: gas (pyrolysis gas), liquid (coal tar), and solid (semi-coke). Pyrolysis gas, coal tar, and semi-coke are further converted into oil, gas, electricity, heat, and organic chemical products.
The Delta LRC pyrolysis process is developed based on Delta's unique high-temperature fluidized bed drying technology and its experience in indirect heat exchange lignite vertical moving bed dryers. This process offers the following advantages: extremely low dust content in pyrolysis gas (optimal coal tar quality); precisely controlled pyrolysis temperature to maximize coal tar yield; large capacity for sibnfle unit; and low process costs and investment.

矿渣干法粒化及热回收工艺
戴尔塔公司基于其独特的高温流化床干燥技术，开发了全新的矿渣干法粒化及热回收技术。
粒化后的熔融的矿渣液滴由高温矿渣颗粒冷却，而非以往工艺中采用的冷却水或冷却表面。这实现了最高的能量回收效率和最高的能量回收水平。

Slag Dry Granulation and Heat Recovery Process
Delta has developed a new slag dry granulation and heat recovery technology based on its unique high-temperature fluidized bed drying technology.
After granulation, the molten slag droplets are cooled by high temperature slag particles, not cooling water or cooing surface in the previous processes developed. This achieves the highest energy recovery efficiency and the highest energy recovery level.
