fuel technology in kilns in china

Kiln - WikipediaA chimney stack improves the air flow or draw of the kiln, thus burning the fuel more completely. Chinese kiln technology has always been a key factor in the development of Chinese pottery, and until recent centuries was far ahead of other parts of the world. The Chinese developed effective kilns capable of firing at around.fuel technology in kilns in china,fuel technology in kilns in china,energy efficiency and environmental pollution of brickmaking in chinamaking in China. China's brick industry is characterized by its enormous size and large number of small producers with outdated technologies. More than 90% of the bricks are fired in annular kilns with coal as the predominant fuel, resulting in substantial SO2, CO2 and other air emissions. Based on available energy.
