亮煤与灰煤因结构致密，颗粒中大孔隙少，显微硬度大，灰分少等原因使得它们在燃烧中发生严重破碎；而暗煤颗粒则因相反的原因不发生破碎或仅发生轻微破碎。

Compared with conventional combustion, catalytic combustion is fameless, in which VOC is pre-mixed with air, then passes homogenously catalyst bed and burned efficiently. More significantly,because catalytic combustion may be performed under lower temperature, N2 in air is free of being oxidized into NOX, which is responsible for the formation of acidic rain ,at the same time when catalytic combustion happens.

与普通燃烧方式相比，催化燃烧是无焰燃烧，VOC与空气进行预混合后，均匀通过催化剂床层，在活性粒子的催化作用下实现燃烧，具有很高的燃烧效率，而且催化燃烧能显著降低燃烧温度，避免了其燃烧时将空气中氮气同时氧化，形成氮氧化物，从而避免了酸雨的产生。

These concrete worksare the following:1, a new heterogonous SHS model had been proposed, which first included all the relativematerials characters, such as reactants particle sizes, changeable heat-conductivity and massdiffusion during SHS and so on, and its chemical reaction characters, initial combustion status.This new model made a more precise prediction about the SHS combustion way and itsTechnological characters possible.2, with the heterogonous SHS model, lots of combustion way had been imitated by changesystems relative factors and the rule of the combustion way change had also been studied,chemical reaction in these systems was controlled by a single mechanism.

The strategy involves a staged combustion, where a hydrocarbon fuel added in the second, fuel-rich stage provides hydrocarbon radicals which can react with and finally reduce the NOx formed in the first, fuel-lean stage, such that NOx formed in the first stage reacts with small hydrocarbon radicals present in the second stage combustion, finally leading to N〓, and to HCN which in turn is converted to NO or N〓. Understanding of the chemistry in this second reburning stage is clearly a key to understanding and optimizing reburn technology.

目前消除NOx的主要方法是向燃烧的废气中加入某些化学物质使其重新燃烧(Selective Noncatalytic Reduction of NO processes，SNCR)，RAPRENOx过程是SNCR的主要方式之一，其实施是向燃烧产生的废气中加入异氰酸，异氰酸在高温下经一系列包括NCO的自由基反应，可以从燃烧的废气中迅速除去NOx化合物。

Co-firing characteristics of corn stalk and stone coal in different proportion were investigated by thermal gravimetric analysis. The results showed that corn stalk can improve the ignition and combustion of stone coal. The agglomeration experiments on corn stalk were made in a bench-scale bubbling fluidized bed with quartz sand as bed material and stone coal ash as additive. The results indicate that stone coal ash can inhibit agglomeration of bed material particles at temperature of 900℃. Agglomerate of blends was analyzed by means of scanning electron microscopy, energy-dispersive X-ray, and the bed materials were analyzed by means of X-ray fluorescence. Analysis showed that aluminum element and iron element in stone coal ash can react with alkali compounds and eutectics with low melting point, form a covering layer with high melting point on the surface of biomass and quart sand particles, thus inhibit the forming and transfer of low melting compounds.
