Grate kiln system

Aug 04, 2015· The schematic figure of grate–kiln–cooler process for iron ore pellets is shown in Fig. 2. Processing of green pellets prepared from pelletizer is accomplished by three equipments: traveling grate (drying and preheating), rotary kiln (roasting) and circular cooler (cooling).

Research on Control Mechanism Model of Grate Cooler …

Induration (drying and hardening) of iron ore pellets is an energy-intensive feed preparation step for both the blast furnace and direct reduction routes to iron. It is commonly carried out by a 'grate/kiln' process. A mathematical model of the process is described, in which mechanistic models of the grate furnace, kiln, and cooler are linked to enable simulation of the entire …

Direction of kiln Rotation

The Grate, the Kiln and the Cooler. The object of the process is to transform the pelletized concentrate into hardened pellets that can be used as blast furnace feed or direct reduction furnace feed. The Travelling Grate is where pellets are dried and then heated up to a temperature of about 800-900 deg C.

Oct 08, 2020· IKN Grate System Horizontal air jets on the grate surface support the clinker transport, resulting in a reduction of movable rows. The size of the Coanda Wing® plates was selected to allow modular adaption of the grate width for varying kiln capacity. For further information, see all sizes available.

kiln cind the grate cooler, was not studied. This neglect of the grate cooler was a serious limitation of the simulation research that has been conducted on the process. The cooler . 6 is known ( by the operating personnel) to have a definite

China Grate Cooler

the static primary grate and the central grate guide) are so designed that they can be retro fitted in nearly all available makes of reciprocating grate coolers. For cooler and kiln system conversions they therefore offer an ideal basis for boosting efficiency and availability with the minimum of investment.

GRATE COOLER

As shown in Fig. 1, high temperature clinker get into grate cooler from rotary kiln. Clinker layer moves slowly on grate bed. Cooling air blows into the clinker layer vertically from the bottom of the clinker, permeates and diffuses in the clinker to cool the red-hot clinker. Cooling air becomes hot air after exchanging heat energy with ...

For large capacity plants, a great cooler is preferred one [7]. Fig. 1 presents the schematic of a typical grate clinker cooler. In a grate cooler, the clinker comes out of the rotary kiln at a high temperature of 1380 _C and it is cooled by fresh incoming air at a temperature of 65 _C through a cross-flow heat exchanger.

Consequently, fossil carbon emissions would be reduced as the ... The cooler model showed that to maintain adequate pellet cooling, the mass flow

A Comparison of Pellet Quality from Straight

Grate Cooler is a kind of quench cooler. Its principle is to quench clinker which is laid in levels on the grate plates with cold wind from air blower. Temperature of clinker will be rapidly dropped from 1200d egree to be less than 100 degree.

METHOD AND APPARATUS FOR ROTARY KILN CONTROL

the kiln). • Thermal stresses (due to uneven exposure of the plates to the hot clinker vs cold air). «THE» solution to keep it cool! cooler grates SOME RESULTS Our solution: the patented Bar Grate Design for optimal cooling through: • Special air distribution system. • Cooling of grates AND clinker. • Strong resistance against

cooler grates

A clear distinction between the dustiness of grate-kiln and straight-grate fired pellets is established. We conclude that grate-kiln-cooler systems provide superior pellet quality, but at the cost of some pellet production rate.

A mathematical model of the process is described, in which mechanistic models of the grate furnace, kiln, and cooler are linked to enable simulation of the entire …

Cement kiln

Dec 18, 2019· As an important process during the cement production, grate cooler plays significance roles on clinker cooling and waste heat recovery. In this paper, we measured experimentally the heat balance of the grate cooler, which provided initial operating parameters for optimization. Then, the grate cooler was simplified into a series-connected heat exchanger …

HEAT EXCHANGE MODELING OF A GRATE CLINKER COOLER

Grate Cooler. Industrial Clinker Cooler is extensively used to cool the clinker and extracted heat from hot clinker is supplied at secondary and tertiary air to kiln. Acknowledged for its optimum specific grate load, this ensures lower heat consumption.

Modelling of heat recovery in LKAB's grate

Mar 21, 2015· Fig 2 Typical schematic diagram of straight grate system. The grate-kiln system depicted in Fig 1 consists of a traveling grate for drying and preheating the pellets to about 1040 deg C, a rotary kiln for uniformly heating the throughput to the final induration temperature of 1315 deg C, and an annular cooler for cooling the product and heat recuperation.
