Dry quenching and wet quenching
Thread Content
The advantages and disadvantages of the two, how can wet quenching be transformed into dry quenching?
Just build a new set of waste heat power generation system for dry quenching of coke
It is also not appropriate for relatively small coking enterprises to install waste heat power generation systems. Dry quenching of coke seems to be the mainstream trend at present, but issues such as dust and coking wastewater cannot be properly addressed, and the investment required is high. We have installed two dry quenching systems, and we are preparing to build a third one. We have also conducted experiments on closed-type coke quenching; those who are interested can discuss this further
Could you briefly explain the idea of closed coking?
Given the increasingly strict environmental regulations, adopting dry quenching of coke is an inevitable trend. For steel complexes, dry coke offers significant advantages: it ensures stable blast furnace operation, minimal fluctuations in furnace temperature, lower energy consumption, less wastewater generation, and compliance with environmental standards. Heat recovery is insufficient; there are large fluctuations in the moisture content of wet quenched coke, a large amount of wastewater is generated, causing severe environmental pollution (in the atmosphere), and it also hinders the operation of blast furnaces.
Wet quenching of coke requires less investment, but it generates waste gas emissions； Dry quenching of coke requires large investment, can generate electricity, and produces no exhaust emissions. Dry quenching of coke can adopt an alternative investment model.

Currently, dry quenching of coke is being mandated – the main purpose is to address air pollution issues. The investment required is extremely high, often reaching hundreds of millions of dollars. What should smaller coke plants do if they opt for dry quenching but not for generating steam? After adopting dry quenching, I now face problems such as excessive dust and difficulties in treating wastewater; there are many issues within this industry, which is why we have turned to closed-type coke quenching methods
