无烟煤荷电煤粉流燃烧实验研究
STUDY ON COMBUSTION EXPERIMENT OF THE CHARGED PULVERIZED ANTHRACITE FLOW
摘要
Abstract
Based on the pulverized coal combustion efficiency and low pollution into consideration, in order to confirming the theory of corona coal powder flow enhanced ignition and combustion, the combustion test research on charged pulverized anthracite flow was finished. U-sing pneumatic screw micro-feeding powder for pulverized coal supply and transportation, the use of corona charging appliance of the pulverized coal particles in electriccyclone, connected to the drop tube furnace pulverized coal combustion in a stream of visual completion, using high resolution digital photographic equipment finished the records of the ignition and combustion state, with the aid of special software for image analysis. By means of thermogravimetry for some residua samples, proceed with the exploration of charged pulverized coal flow complete combustion characteristics. Comparing the charged anthracite powder flow with general anthracite powder flow, the results of the experiment analysis show that , the ignition distance and ignition delay of charged anthracite powder flow is about 5% and 6% ahead of percentage, is about 21% increased combustible matter consumption at least. The charged pulverized coal flow combustion displays better effectiveness of enhanced ignition and combustion.关键词
