【摘要】 本文介绍我所进行PFBC技术首阶段试验研究的情况,发表了五次试验的主要结果。燃用高灰煤时,燃烧效率可达97％～98％。对于中等含硫的煤,Ca/S比在1.5～1.8时,可达80％～85％的脱硫效率。燃气通过高温除尘系统后,含尘量为189mg/m~3(标),颗粒平均直径2.5～3μm,其中大于10μm的不超过3％。更多还原

【Abstract】 The experimental research work in first stage in China on pressurized fluidized bed combustion（PFBC）technology is introduced,and results of five tests are presented.The combustion effcieney could be as high as 97%～98%,when high ash content coal was burnt in PFBC,and the desulfuriation effriciency be 80%～85% with Ca/S mole ratios in between 1.5～1.8.The particulate content in flue gas at outlet of high temperature gas clean-up system was 189 mg/m^-3（normalized）.The average diameter of partieles were 2.5～3×10^-3mm,and the weight of particles with diameter larger than 10×10^-3mm was not greater than 3%.更多还原
