KELESS COAL BRIQUETTES AS A POSSIBLE SUBSTITUTE FOR
FUELWOOD
SQME CON BRIQUETTING TECHNIQUES MAKE COAL AN ATTRACTIVE
FUELWOOD SUBSTITUTE BY CONVERTING IT INTO A SMOKELESS,
COMPACT, STABLE, AND INEXPENSIVE FORM OF FUEL.
COK BRIUUETTING HAS BEE3 SH N WORLD-WIDE TO BE A
TECHNOLOGY CAPABLE OF USING COAL OF VARIOUS GRADES AND
PRODUCING BRIQUETTES WITH DIFFERENT CHARACTERISTICS FOR
DIFFERENT USES.
OR UNTREATED BRIQUETTED COAL PRODUCES EMISSIONS
THAT CAN HAVE SERIOUS HEPLTH EFFECTS.
HWEVER, CON CARBONIZATION SIGNIFICANTLY REDUCES THE
ADVERSE HEALTH EFFECTS FROM BURNING COAL OR COAL
BRIQUETTES. THE RESULT OF CAFa88NIZATION IS A "SOFT
SMOKELESS COKE. WHILE TESTING IS CURRENTLY IN PRGRESS,
EMISSIONS FROM SMOKELESS COAL ARE PREDICTED TO BE NO WORSE
MCVJ 'THOSE EMANATING FRON THE CURRENT FUELS OF CI-lARCOK AND
F I REW OOD.

THE COSTS ASSQCIATED WITH BRIQUETTING AND CARBONIZING CON
INDICATE A SELLING PRICE FOR SMOKELESS COAL BRIQUETTES IN
SOME UWAN AREAS THAT MAKE THEN COMPETITIVE WITH FUELWOOD
AND WARCONL.
INTERNATIONAL EXPERIENCES WITH COAL BRIQUETTING:
KOREA
INDIA AND
COAL CARBONIZATION HAS BEEN PRACTICED EXTENSIVELY IN INDIA.
THE INDIAN EXPERIENCE IS INSTRUCTIVE BECAUSE A WIDE RANGE
OF TECHNOLOGIES AND CO TYPES HAS BEEN UTILIZED. INDIA
HAS DEWSITS OF BITUMINOUS# SUBBITUMINCUSt AND LIGNITE
COALSa AND ALL HAVE BEEN USED FOR CARBONIZATION.
TECHNOLOGIES RANGE FROM ONE-PERSON, "VILLAGE COPe PILES" TO
ADV AFlCED TECHNOL CGY CARBONIZATION hz. ANTS.
INDIA HAS DEVELOPED A SMOKELESS COOKING STOVE WHICH CAN USE
COAL AS A FUEL SOURCE WITH NO SIGNIFICANT ADVERSE
HEKM EFFECTS.
KOREANS HAVE USED R ANPH RACITE COAL BRIQUETTES
EXTENSIVELY FOR COOKING AND HEATING. THE KOREANS STARTED
CQPL BKIQUETTING IN 1930s AND THERE ARE NW APPROXIMATUY
20 LARGE BRIQUETTING RANTS IN ME CQUNTRY.
