Standardisation of the Procedure
of Sampling and Analysis
The Existing Practice
Sampling from wagon top
Normally the sampling methodology that is being implemented
conforms to one of the standard procedures like BIS/ISO/ASTM, etc.
However, very often due to technical, time and cost constraints strict
implementation of the standard procedures becomes difficult and in such
cases simplified sampling method is implemented with the mutual consent of
the different stakeholders. The pertinent point that needs to be looked into is
that the fundamental principles of sampling are not compromised and more
importantly the precision of the measurement.
It is an established fact that more than the 80% of the total variance
arising during the different stages of sample collection, preparation and
analysis come from the sampling procedures. Sampling variance is a function
of fuel variability so that the same number of increments, sub-lots, preparation
and testing errors can yield different precision with fuels of wide variability.
Efforts are to be made to reduce the sampling variance as far as practicable
and both the sellers and purchasers need to agree to the limit that is
practically achievable.
What do CFRI offer
ƒ
Estimation of the increment variance
ƒ
Estimation of preparation and testing variance
ƒ
Design of sampling scheme to achieve a desired precision level
Benefits to client:
♦ Knowledge of the precision level achievable in a sampling scheme helps to
identify the tolerance limit on any quality parameters for commercial
transaction.
♦ It provides a rational basis for comparing the results obtained at the seller and
customers end.
Time : Forty five days
Cost : Rs 12.00 lakh (Approx)
Testing of Bias of Auto Mechanical Sampling System
Existing Set Up
AMS with falling-stream type sampler
Cutter chute type
Cutter bucket type
Swing arm type
AMS with cross-belt type sampler
Normal sweep type
Angled sweep type
(Size of coal : 200/100/50/20 mm)
Testing for bias is not always done for a single purpose. The objectives
of testing of bias may be for assessing conformity with contractual
requirements, such as guarantees or purchase and acceptance
specifications, for diagnostic purposes or both. This is more important if
the results from AMS are used for commercial transactions between the
customer and seller.
It is not possible for any scheme of sampling, or sample preparation and
analysis to be free of errors of measurement. For this reason, no
statistical test can establish that there is no bias, but only that there is
not likely to be a bias of more than a certain magnitude.
The following terms which forms the basis of sampling from AMS,
though often ignored, should be taken into consideration during
designing and implementation of a sampling scheme i.e. number of
increments, quantity of sample, number of sub-lots, precision and
relevant bias of the system.
CFRI offers
♦ Fine tuning of the existing system
♦ Performance of individual components of the AMS
♦ Estimation of Maximum Tolerable Bias following ISO procedure
♦ Sampling Scheme
Benefits to Client
Estimation of the relevant bias of an AMS helps to identify the deviation from the
true value obtained from an intrinsically unbiased system and adopt corrective
measures to minimise the bias of the system to use it for routine quality
monitoring purpose.

QUALITY MONITORING OF COAL
Quality monitoring of coal for any end uses requires proper
implementation
of
standard
sampling,
preparation
and
testing
procedures. The design of sampling scheme may vary depending on the
purpose like process control, evaluation of plant performance,
commercial transaction, etc. for which the sampling methodology has to
be executed.
The primary reason for sampling is to estimate the quality parameters
for commercial transaction. The producer is required to check that the
daily despatch complies with the contracted agreements, and the
consumer in turn needs to check the quality and the quantities of the
coal received. The object of collecting a sample of coal is to obtain a
representative portion from the whole consignment that serves for the
determination of the qualities of coal concerned. As no sampling and
analyses procedures are free of errors it is absolutely necessary to
identify the bias of the system and the repeatability of results obtained
by the sampling scheme being practiced.

YOU KNOW THAT
Ground Stock Management is an important activity for any body who is handling large
quantity of coal – be it the producer or the customer. Besides the loss incurred due to wind
or handling/transportation the problem of spontaneous combustion in stacks is of much
serious concern. Very often coals of different sizes from various sources are arranged in
stacks and it is observed that some stacks are more prone to spontaneous combustion. This
proneness to auto oxidation is primarily depended on the coal characteristics and the
tendency to spontaneous combustion is a complex function of coal characteristics, size of
coal, stack preparation, shape & size of stacks, moisture content and the environmental
conditions.

COAL CARBONISATION
Coke making had been one of the major pursuits of CFRI since
inception. Fundamental research on coal science and the
carbonisation process found its applications in the development and
transfer of various technologies on HTC coke, formed coke, briquettes,
soft coke at different point of time. Keeping in view the gradual
depletion of indigenous good quality coking coal resources , R&D
initiatives at CFRI provided the scientific basis and scope of utilising
different type inferior grade coals as blend components for
metallurgical coke making. Extensive R&D on carbon product from
coal tar & pitch has also been done. Application of the
knowledgebase backed by validation tests in pilot plants has helped in
optimising the blend components for various steel plants utilising both
indigenous and imported coals.
Compelling factors like severe environmental regulations on coke
making technologies, market competitiveness and demand activated
the development of environment friendly improved design for coke
making which have already entered the market. CFRI with its built in
expertise in the area of carbonisation is in a ready state of
preparedness to provide not only specialised services but would
remain a key player as a technology provider to the growing coke
making industries.

POWER COAL DIVISION
Coal Combustion has been an important area of pursuit since inception.
Extensive studies were carried on fluid bed combustion for development of
FBC boiler, generation of hot air from agro – waste, coal and lignite, inert
gas generation, Coal Water Mixture. The present initiatives are focused on
studying the impact of coal quality on the different aspects of pulverized
coal combustion.
Modern test facilities of different scale and under different flow condition
like Drop Tube Furnace and Fuel Evaluation Test Facility would provide
valuable insight on the role of different quality parameters on carbon
burnout, flame stability, and slagging and fouling propensities etc.
Blending of coals for power generation is another area, which is being
studied extensively with emphasis on the issues related to blending of
dissimilar coal on the milling, burnout and ash deposit problem.
Keeping in view the emerging trend of use of Computational Fluid
Dynamics software in the area of coal combustion initiatives has been

GASIFICATION DIVISION
Coal Gasification
Coal, the most abundant and affordable fossil fuel will remain the major
source of energy in the coming days due to devolatilization of petroleum feed
stock for various applications. At the same time, presently, the majority of coal
produced in India is of high ash low rank. The coal gasification, the process of
breaking down coal in to chemical components and fuels prior to combustion, is
needed to meet efficient utilization of such coals. CIMFR is presently involved in
carrying out R&D work in the area of coal gasification and also rendering
technical support/services to coal based industries in the nation. This includes
prediction of quality of gas (within a probable range) produced from a particular
coal as well as selection of correct feed for conventional as well as modern
gasifier. Our group, consisting of scientists, engineers and technocrats are able
to provide fruitful suggestion for the troubleshooting points and also in design
aspects of fluidized bed gasification. As such, CIMFR scientists have represented
various committees and have been invited by abroad countries in the area of
gasification including underground coal gasification.
Our Institute is equipped with various facilities (well equipped laboratory)
in terms of equipment/instruments as well as experienced capable scientists.
They are related to different disciplines such as, Surface chemistry, Analytical
chemistry, engineering design etc. and all under one roof of the gasification
division.

ENVIRONMENTAL MANAGEMENT
Capability
Environmental problems are inseparably
associated with coal conversion and processing.
CIMFR-Digwadih Campus is copiously involved
in carrying out R & D work in the area of
environmental management related to coalbased industries. This includes the monitoring of
quality of air (aerosols, biotic/abiotic particulates),
water,
soil
and
suggesting/developing
appropriate methods for their minimizing/
abatement; development of environmental
standards, soil quality index; making
environmental impact assessments and
management plans; mitigation of GHGs;
management of solid waste from coal-based
industries, principally the fly/bottom/pond ash
from TPPs and mine refuse/spoil generated
during mining operations, besides addressing the
associated environmental problems. In the
context of sustainable management of solid
waste from TPPs, systematic R & D work has
been successfully carried out, over the past one
and half decades or so. This comprises detailed
physico-chemical
characterization
and
determination of potentially toxic trace/heavy
metals and radionuclides in coal ash and its bulk
use in brick making and agriculture/forestry
sector (as liming agent, soil modifier and
amendment, source of essential plant nutrients,
and also for the reclamation of waste/degraded
lands/low lying area/mine spoil/abandoned ash
ponds). Besides, R & D work includes the
diversified area for developing the suitable
technology for recovery of some of the valueadded products. The institute also organizes
national/international symposia/seminars and
training courses on various R & D activities from
time to time.
