Bamboo Wastes as Fuel in Industrial Boiler in China

Abstract

: It is estimated that more than 500,000 industrial boilers (mostly stoker-fired) in China consume over 400 million tons of coal per year. Because of low efficiency (only 60-65 percent) of industrial boilers, the energy consumption and pollution emissions from industrial boilers rank second place in China’s industry. On the other hand, China is rich in bamboo resource, and bamboo forest area is more than 5 million hectares, and occupies more than 1/4 of the world’s total. However, the common utilization rate of bamboo timber’s physical processing is below 40% in weight, over 60% of bamboo timber becomes left over when processed. Bamboo wastes, compared with coal fuel, are a very clean and renewable and sustainable energy. Therefore, there is the requirement that coal fired industrial boiler change its fuel into bamboo wastes in China, and some suggestions for bamboo fired boiler are presented in this paper. It is well economy of bamboo fired boiler in the region of China where an abundance of bamboo wastes disposed.
