In the past, South Korea’s domestic fuel, mainly from wood and straw and other agricultural. Since 1952, the development of briquette coal has become a cheap and convenient fuel and has made great achievements in modernizing family fuel and protecting mountainous villages.

Ignited cake made of charcoal material, 35 mm thick. Each piece of coal weighs 3.2 ~ 3.6 kg. Each piece of total heat 14850 ~ 1500 kcal, with special stove combustion, effective heat 11880 kcal, thermal efficiency 80%. National production capacity of 18 million, about 50,000 tons; the average annual market size of 23 million tons. Production companies to focus on production methods, the use of double punch stamping
