By use of a fan (extractor), these particles evolved by the raw materials, are drawn out of the rotary kiln and collected for its treatment. Particles are captured by means of such extractors, which flow is efficiently controlled with a frequency converter which controls the motor and coupled fan. STUDY. Kiln Exhaust ID Fan Cement Plant

Lime Kiln ID Fan Upgrade Project The Problem In 2014, AirStream contacted an East Coast pulp mill presenting a unique approach to evaluating problems with dust build-up on the mill’s No.1 and No.2 Lime Kiln ID Fans. Due to high vibration caused by scaly build-up, the fans

The total flow through the kiln is induced by the large ID fan located at the outlet of the kiln system and prior to the stack. ID fans are called dirty fans because unlike forced draft fans for primary air, and other uses, ID fans handle the gases produced by combustion, dust that might be entrained and not collected in the bag filter, the

Feb 14, 2012 Good morning everybody, I have an ID fan driven by a 2800kw motor.In the full speed operation 1000 rpm at no load,the vibration on the fan inboard brg and outboard bearing is acceptable,only 2mm/s in Horizontal.But when we put it in full load operation,the vibration on inboard brg jumped up 4.6mm/s in horizontal.Before this fan has the problem with unbalance impeller due to build

The ID fan problems have arisen from the bearing lubrication system which provides oil recirculation to the induction motor bearings and fan main shaft bearings. Consequently these issues have caused half-load unit (225 MW) run-backs and full unit (450 MW) trips over the past decade. This project’s aim is to analyse the ID fan lubrication

Dec 13, 2016 An ID fan is required to induce flow through the rotary kiln to facilitate the chemical reaction. This flow is normally heavily laden with dust (5-20gr/ft ), requiring scrubbing/cleaning equipment, which is often downstream of the ID fan. The heavy dust load passing through the ID fan represents a major problem for mills, as the dust sticks to

Jan 19, 2019 The ID fan induces kiln airflow, which must be continuously varied to match the process requirements. Because cement production is a thermal and chemical process, both air volume and mass flow must be controlled.

complete combustion. The Induced Draft (ID) fan at the cold end of the kiln is the main gas moving fan. It pulls the combustion products, carbon dioxide from calcining, and the water vapor from the wet mud out of the cold end of the kiln. The ID fan is used to control the total air flow into the kiln for combustion
