Coal blending - Wikipedia

Coal blending is the process of mixing coals after coal has been mined to achieve quality attributes that are desirable for the coal's intended application (e.g. steam generation, coking). The quality attributes that are most important in blending will differ from one mine site to another and also depend on how the coal seams vary in quality and their final intended use.

Coal Classification, Blending, and Requirement

Coal blending can be done at coal mine end, at transshipment point or at the power station. The method chosen depends upon site condition, level of blending required. Normally in large thermal power stations stacking method with the fully mechanized system is followed. It is found that even if blended coal closely resembles the design coal boiler, the blend does not perform similar way. This ...

Coal Blending - an overview | ScienceDirect Topics

For blending of ple coals, blending calculations are best performed using the simple tabular format shown in Table 17.1. The total ash content of the mix is calculated by dividing the total tons of ash by the total tons of coal (i.e., 2400/25 000 = 0.096 = 9.6%). Simple weighted averages can be used to calculate a variety of common assays for mixed coals such as ash, sulfur, calorific ...

Blending Influence on the Conversion Efficiency .

Characterizations of biomass and coal were undertaken in order to compare their properties and determine the combustion characteristics of both feedstocks. The study was also intended to establish whether the biomass (corn stover) used for this study is a suitable feedstock for blending with coal for the purpose of cogasification based on composition and properties.
