Coal Blending. Coal blending is a process of uniformly combining two or more kinds of coking coal in appropriate proportions to obtain the required blended coal. It is a preparation process of coal charges before coking. Coal blending can ensure the quality of coke meets the requirements and also can reasonably utilize coal resources.

The blending with lowquality coal is 15% maximum in the wet system, and it arrives to 30% in the dry configuration. By converting coke ovens (50 t/h capacity) from wet to dry, a reduction of over 130,000 t/year of CO 2 can be reached; this corresponds to 8% of net reduction of CO 2 emissions in the atmosphere.

All coals are assumed to be homogeneous because there is no blending or mixing process. The distribution of coal is carried out directly from the barge to the boiler bunker. The coal sample is carried out at least five times at the coal feeder inlet, and coal quality is determined through proximate analysis using Bomb Calorimeter LECO AC600 ...

Name : Nia Ariningtyas NRP : 2112 204 805 Advisor : Prof. Ir. Sutardi,, PhD ABSTRACT . PLTU Rembang is one of power plants that using two types of coal, medium range coal (MRC) and low range coal (LRC). This two kinds of coal mixed together using infurnace blending method. In this method each coal is fired by each burner without prior blending in the coal bunker, conveyor or coal yard.

The coal handling system extends from the coal stockpile adjacent to the rail yard to the bunkers for BLE1 and BLE2. The material handling system (shown to the left of the main conveyor in Figure 1), located adjacent to the crusher house, is for handling tire derived fuel, a supplemental fuel that is not currently fired at B. L. England Station.
