一、什么是焦化：

1、 What is coking:

上升到化学层面：焦化是一个涉及有机物质在高温下发生化学变化的过程。

Ascending to the chemical level: Coking is a process involving chemical changes in organic substances at high temperatures.

既然是有机物，那就是不同的有机物以及不同的用途，焦化有不同的定义和用途。

Since it is an organic compound, coking has different definitions and uses depending on the type of organic compound and its purpose.

焦化有主动焦化和被动焦化之说。

There are two types of coking: active coking and passive coking.

主动焦化，是91麻豆产精品久久久久久夏晴子想要，例如，烧炭，炼焦。

Active coking is what we want, for example, charcoal burning, coking.

被动焦化是91麻豆产精品久久久久久夏晴子不想看到，但又必须面对和处理的，例如发动机积碳，化学反应中在催化剂表面的积碳。

Passive coking is something we don't want to see, but we must face and deal with, such as engine carbon deposits and carbon deposits on catalyst surfaces in chemical reactions.

先说炼焦：也叫干馏。

First, let's talk about coking: also known as dry distillation.

在一个密闭的空间，像一个大抽屉（叫捣鼓炉），把要加工的煤，通过混配放进去（叫配煤）；然后在抽屉的两面烧火，加热；上部气体排入指定的富集区内处理。

In a closed space, like a large drawer (called a pounding furnace), the coal to be processed is mixed and put in (called coal blending); Then burn fire on both sides of the drawer to heat it up; The upper gas is discharged into the designated enrichment zone for processing.

剩下的就是焦炭，或者是精化煤；跑出去的气体，常温冷凝的，叫做焦油，不凝的，叫做粗煤气。后两部分后续的深加工，形成了煤焦化工产业链。

The rest is coke or refined coal; The gas that runs out and condenses at room temperature is called tar, while the non condensable gas is called crude gas. The subsequent deep processing of the latter two parts has formed the coal coke chemical industry chain.

煤的加热的温度高低与煤种以及用途有关。又分为中焦和高焦。

The heating temperature of coal is related to the type and purpose of the coal. It is divided into medium focus and high focus.

中焦温度在500度左右，主要是对褐煤等年轻的煤种进行初步处理，焦煤用于化工或者锅炉用。例如，兰炭用于电石。

The medium coke temperature is around 500 degrees Celsius, mainly used for preliminary treatment of young coal types such as lignite. Coking coal is used for chemical or boiler applications. For example, blue charcoal is used for calcium carbide.

其气体部分氢气组分较低，用于一般的燃气较多。

The hydrogen component of its gas is relatively low, and it is more commonly used for general gas.

高焦温度在950—1050℃，产生的焦炭主要含碳，作为重要的还原剂，用于炼钢等冶金行业。再具体点，焦炭就是为炼钢而生的。其荒煤气（含多种化学产品）和焦油等副产品是很重要的化工产业链之一。

The high coke temperature is between 950-1050 ℃, and the resulting coke mainly contains carbon. It is used as an important reducing agent in metallurgical industries such as steelmaking. To be more specific, coke is produced for steelmaking. The raw gas (including various chemical products) and by-products such as tar are important in the chemical industry chain.

二、了解焦化发电机

2、 Understand coking generators

焦化发电机是一种将焦化工艺与发电技术相结合的创新能源系统，主要应用于钢铁、焦化等重工业领域。该系统通过回收利用焦化生产过程中产生的高温焦炉煤气和余热资源进行发电，实现了能源的梯级利用，是工业领域节能减排的重要技术装备。

Coking generator is an innovative energy system that combines coking technology with power generation technology, mainly used in heavy industries such as steel and coking. This system generates electricity by recycling and utilizing high-temperature coke oven gas and waste heat resources generated during coking production, achieving cascading energy utilization. It is an important technical equipment for energy conservation and emission reduction in the industrial field.

焦化发电机的核心在于对焦化副产物的能量回收。在焦化过程中产生的焦炉煤气（温度约700-800℃）首先经过净化处理，去除其中的焦油、硫化物等杂质后，进入燃气轮机或内燃机燃烧发电。同时，系统还回收利用焦炉烟道气（300-400℃）和红焦显热（1000℃以上）等余热资源，通过余热锅炉产生蒸汽驱动汽轮麻豆性视频网，形成燃气-蒸汽联合循环发电系统。

The core of coking generators lies in the energy recovery of coking by-products. The coke oven gas produced during the coking process (with a temperature of about 700-800 ℃) is first purified to remove impurities such as tar and sulfides, and then enters the gas turbine or internal combustion engine for combustion and power generation. At the same time, the system also recovers and utilizes waste heat resources such as coke oven flue gas (300-400 ℃) and red coke sensible heat (above 1000 ℃), and generates steam through a waste heat boiler to drive a steam turbine generator unit, forming a gas steam combined cycle power generation system.
