How to deal with coking in the furnace
Thread Content
Could some teacher please explain the most practical way to deal with coking in furnaces? Thank you:handshake
What kind of furnace are you referring to when you talk about coking? If it’s a vaporization furnace, the simplest and most straightforward method is to use an iron rod to strike it from the top of the furnace, using a crane for that purpose. Another option is to raise the temperature of the vaporization furnace; this can also solve the problem.
The furnace is a cylindrical furnace, an atmospheric-pressure furnace – the most common type.
I wonder if steam can be injected to remove coking, as is done in coking furnaces, or if blasting could be used for this purpose.
Can a pneumatic hammer be used? This is how we deal with scarring on the furnaces in our factory; if the affected area is too large, it’s a bit embarrassing.
I don’t know what material it is. Is burning it okay?
Use an iron rod to be lifted from the top of the vaporization furnace by a crane and then used for impact
I’m not sure whether it is possible to use 4.0 Mpa medium-pressure steam and 5.9 Mpa deionized water for online coking removal technology.
What is this furnace mainly used for?
Furnaces generally don’t have burning lines! Just use it!
Steam at 0.59 Mpa can be used for purging; if that doesn’t work, the furnace should be opened and cleaned with a high-pressure water gun, or with a weak acid solution
Our company uses pneumatic hammers to break down the coking that forms in hot air stoves; we just don’t know what the composition of that coking is
Just joking – be careful someone might take it seriously. :lol
Burning it by introducing steam and air – I wonder if that will work!
The chemical method involves cleaning using the QX R-3 hot oil furnace cleaner, while the mechanical coking removal method makes use of a rotatable metal hose; under the action of a high-speed rotating drill bit, it breaks through the blocked coking deposits and also scrapes off the thicker layers of coking material attached to the pipe walls.
It was burned either by high-pressure water jetting or by introducing air
For atmospheric-pressure furnaces, a burning system is sufficient; steam and air are used to interact within the furnace tubes to burn the coke at a certain temperature, but care must be taken to ensure that the temperature does not get too high. It depends on the material of the furnace tubes as to what temperature they can withstand. Atmospheric-pressure furnaces generally do not exceed 500 degrees
