Compared with coal,biomass volatilization and combustion time is short, so boiler combustion efficiency can be guaranteed. Chemistry dynamics calculation is made on biomass volatilization deoxidizing NO.

本文还尝试了通过生物质挥发分同相还原NO的化学动力学计算来对生物质燃料的再燃进行模拟，计算结果和试验结果规律是一致的，说明该模型是合理的。

With the increasing of NO3- concentration, the biomass, root absorbability and root absorbing area declined under NaNO3 treatment. The biomass was gradually increased with NO3- concentration increasing under Ca(NO3)2 and KNO3 treatments, while NO3- concentration excessed 98 mmol·L-1, the fresh weight of cucumber seedlings was gradually decreased.

NaNO3处理条件下，随着NO3-浓度增加，黄瓜幼苗生物量降低、根系吸收能力及吸收面积下降；而低浓度Ca(NO3)2及KNO3处理下，黄瓜幼苗生物量随着NO3-浓度增加而增加，当大于98 mmol·L-1时，黄瓜幼苗鲜重逐渐降低。

So the possibility of the powder quantity excessing the furnace's limitation pressure must be noticed . In conclusion, compared with combusting biomass in the initial condition, the method of combustion biomass in powder by the circumfluence furnace can greatly improve the combustion properties and effiency.

与传统的直接燃烧未破碎的生物质相比，粉体在回流式燃烧炉中燃烧的方式改变了破碎前生物质以固相燃烧为主的性状，极大地提高了生物质的燃烧效率和能源品位。

Theoretically, almost all kinds of biomass with moisture content of 5-30% can be gasified, however, not every biomass fuel can lead to the successful gasification.
