What are the advantages of Cement kiln disposal of sewage sludge

Posted in: , on 31. Jul. 2015 - 13:17

The advantages of disposal of sewage sludge by cement kiln than by professional incinerator

High treatment temperature

Temperature in cement kiln can reach 1800 ,the burn rate of harmful ingredient in the mainly organic matter can up to 99.999%, even the stable organic matter can also be completely decomposed

Burning atmosphere stable

Cement kiln is a large rotary cylinder, not only can handle large amounts of waste, and can maintain a homogeneous, stable burning atmosphere.

Long Incineration

Sludge stay a long time at the high temperature furnace, burning fully.

Large-scale treatment

New cement kiln treatment sludge accounted for about 2% of kiln production.

Alkaline cement kiln atmosphere

Avoid "secondary pollution" resulting by burning exhaust gas of common incinerator

Cement kilns burning hazardous waste

Allows solidification of potential presence metal elements in hazardous waste, plays a dual role of exhaust gas purification and heavy metals high temperature curing in mineral admixture.

Cement kiln system is operated in Negative pressure

Smoke and dust will not spill out, to prevent the re-contamination radically in the process.

Cement kiln treatment sludge

Because of the sulfur absorption effect of theburning process, integrated emissions of pollutants was improved and reduced.

Refractory bricks in Cement kiln

Firebrick, raw materials, kiln coating and clinker are alkaline, can absorb SO2, thereby suppressing their emissions.

Verbosity Gone Mad!

I suppose this one deserves a reply so here goes.

What the thread starter is really saying is that you can do away with the incinerator if there is an already available alternative.

Well, yes!

What the thread stater fails to mention is the consequences of the kiln going out of service. How does he propose to stop sewage production?

This thread starter is one that is simply C&Ping articles in order to get a link to their website included (very typical for the Chinese). I am getting very tired of deleting them. I have already warned him/her but I doubt they understand English well. If it continues they will be banned.

I do not mind if they are involved in helping others but this lame attempt to get free advertising does sit well with me.

Burning Sludge In A Kiln

What they fail to say is that if you intend on burning sludge or any waste in a kiln (tires are very popular) this should be designed in at the conception. If you don't then your Nox and Sox will be very problematic and you will have problems with your stack emmissions. I have yet to see anyone making cement as a by-product of disposing of waste sludge. Using alternate fuels when making cement makes sense

Put A Chink In Their Armour.

I was hoping that this guy might get embarrassed by his blatant attempts to advertise and eventually disappear.

I'll try again: harder.

After all, there is a funny side to his stories.

Things are slowing down on the Chinese belting market and I am only getting emails every other day now.

Often enough we are offered machines from that part of the world which show us exactly what not to do. So there is a perversity value engineered into the situation.

Well we don't need to worry about him or her anymore - I permanently banned him/her for ignoring my warning.

I get about 200 email a day and 50 of them are from China - 5 of them from Jenny for the same thing all different email addresses and all blocked now. I even got one today to buy their aluminum foil for hair dressing shops - it was the best in the world. Oh my. And they must think I can read Chinese. Then they want you to confirm that you read the email. UMMMMMM!!!! I don't think so. They are like a mosquito - if you stop one a thousand more come to the funeral.
