Study of burning performance of biomas pellet burner in agricultural use

本文研究了一种生物质颗粒燃烧器及其配套加热装置的燃烧性能。该燃烧器由料斗、给料管、鼓风机和涡流燃烧室组成。主要研究结果如下：1.燃烧器内的燃烧层依次由灰层、氧化层、还原层和炭化层组成，向下依次为灰层、氧化层、还原层和炭化层.燃烧器的燃烧性能受送风量和颗粒量的影响.适宜的燃烧条件为：空气流量4.0 × 10 m/s，球团料流16 kg/h.在实际使用试验中，安装生物质颗粒燃烧器的供热机组，采暖室内温度基本均匀.从以上试验可以看出，配备生物质颗粒燃烧器的加热单元具有很好的实际应用适应性。

This study dealt with the burning performance of a biomass pellet burner and of heating unit fitted with it in the agricultural plant. And the objective of this study was to put it to practical use.This burner consited of a hopper, feeder pipe, air blower and vortex burning chamber. The main results were as follows:1. The burning layer in a burner in turn was consisted of the layers of ash, oxidation , restoration and carbonization to the lower layer.2. The burning performance of the burner was influenced by the qantity of air blast and the quantity of pellets.3. The proper condition of burning was 4.0 10 m/s in the rate of air and 16 kg/h in the feeding rate of pellets.4. In the case of practical use test with the heating unit fitted with the biomass pellet burner, the temperatures in the heating house were nearly uniformity.5. It is clear from the above test that the heating unit fitted with the biomass pellet burner shows great adaptability for the practical use.
