Cyclone Preheater Without Immersion Tube - What is the impact on Kiln Operations?_ English Version

[@haeruddinrudi]

Terimakasih ilmunya pak, ditunggu video selanjutnya jika boleh ada versi Indonesianya

[@parroscement2625]

Insya Allah nanti saya buat yang versi bahasa Indonesia juga pak Haeruddin🙏

Good I worked 38 years in cement in electrical dept . Waste gas fan motors were so critical in this process 😊

Good information ji sir tq so much for giving this information

[@sthapa9632]

Sir are there portable gas analyzer for detecting CO and oxygen at different points at the Preheater cyclone.

[@parroscement2625]

There is Mr. S Thapa. There are several brands of portable gas analyzers, you can search the internet according to the type you want, there is one tool that can be used to measure CO, CO2, O2, SO2, NOX, NO, NO2 and temperature. You also have to complete a Pitot Tube Anemometer to measure the speed of hot gas in each channel of the preheater cyclone.

@@parroscement2625 sir can you name some brands sir

[@parroscement2625]

There are several brands and you can visit their websites, including: Ametek-Land at www.ametek-land.com/, MRU-Instrumente at mru-instruments.com/ , Testo Portable gas analyzer for cement industry at static-int.testo.com/, and others. You can contact the supplier in your country or buy it at an online shop.

Sir what happens if there is pressure drop in the preheater cyclone?

[@parroscement2625]

Thank you for the question sir. If there is a drop in pressure on the cyclone preheater, there are not many obstacles inside the cyclone, meaning that the separation process between the material and the hot gas also decreases. This generally occurs when the inner tube is too short or there is no inner tube.

Sir, i have question calcination level in precalcinator is too high 97.7%, what could be the problem for this? Also the clinker is dusty and kiln operator saying is hard to produce clinker. What cause this impact on clinker quality?

[@parroscement2625]

Thank you for your question sir. To answer your questions, operating data should be supported such as the LSF%, SM%and IM%, Caliner Outlet temperatures. Clinker quality, what is the %freelime value, %C3S and %C2S? Calcination 97.7% can be caused by LSF% below the target and calciner outlet temperature of more than 890 degrees Celsius. Dusty clinker can be caused by high silica modulus or more than 2.65% and iron modulus of more than 1.75%. To overcome this problem you can reduce the use of fuel in calciner and raise fuel in the main burner kiln. And adjust the use of clinker cooling air, especially in room 1 and 2 clinker cooler.

[@parroscement2625]

LSF 95%, SM 2.15%, AM 1.5%, This parameter is too low for the OPC cement production process that uses coal as fuel. This causes high decarbonization process, dusty in kiln operation which can be caused by high ash content and high coal residue. You can reduce fuel consumption in the calciner and switch it to the main burner. If this happens for a long time, there is potential for chocking in the lowest cyclone preheater.

What are the ideal parameters when using coal fuel LSF SM AM

[@nitesh482]

Sir, but if there are no dip tubes and to check the operation we can check the DOC for both C4 and C5 cyclones. If DOC for C5 is 92-94% and C4 is 20% then we can say our operation is going good. Am i correct?

[@photobook3413]

How to calculate cyclone preheater eficiency, sir? and if cyclone lowes stage without immersion tube, how many percent cyclone eficiency will reduced? Thank's in advance sir

Halo Pak Pardi, perkenalkan saya Adrian pak. Saya ada beberapa hal yang mau dikonsultasikan mengenai vertical raw mill, apakah saya dapat menghubungi Bapak pak melalu baik email/whatsapp? Terima kasih 🙏
