Dry quenching coke steam drives the gas blower
Thread Content
Our plant plans to use the steam from dry quenching of coke to drive the gas blower; I wonder if any manufacturers use such a configuration? I’d like to discuss it
It is useful for the dry quenching steam to merge with the steam from the boiler room in order to power the ironmaking blowers; using only dry quenching steam to drive the gas blowers carries certain risks, and even if it is used, an electric gas blower is necessary.
The gas blower can be regarded as the heart of the coking system; any problems with it can lead to emissions from the entire coke oven or even a shutdown of production. In my opinion, it is better to choose a safer driving method for such equipment. The hydraulic couplings currently in use may consume more energy, but they are safe and stable. The emerging variable frequency control method is very convenient to use and energy-efficient, yet its maturity for use in high-power motors is still under investigation. Therefore, I believe that for practical purposes, it is better to use hydraulic couplings for gas blowers, while employing variable frequency control for other motors – which is a viable option for coking operations
The gas blowers in our plant are driven by steam; we are considering using the steam generated by the dry quenching boiler to power these blowers. I would like to exchange ideas with those plants that use this configuration.
Our plant uses steam-based power generation for dry quenching of coke; the excess steam is fed into the grid. In my opinion, as long as the pressure of the steam meets your plant’s technical requirements, there should be no problems
The dry quenching furnace has approximately 25 days of maintenance time each year; if each dry quenching furnace and each boiler is equipped with its own blower, it is impossible to ensure the continuous operation of those blowers! If there are several dry quenching coke boilers that form a pipeline network, ensuring stable gas supply, they can be used as a gas source for gas blowers; generally, an electric blower is also required as a backup. Because turbo blowers have a slow startup speed
