摘要

燃煤机组掺烧生物质被认为是实现降碳的重要技术之一。牛粪是一种典型的草本类生物质，基于内蒙古某660 MW超超临界燃褐煤机组，开展了国内首例大型煤电掺烧牛粪试验，研究了磨煤机碾磨生物质与煤混合燃料的能力，分析了掺混压块牛粪对制粉性能的影响，以及不同负荷下，多台磨煤机掺烧压块牛粪对燃烧特性、飞灰可燃物、锅炉效率及污染物排放的影响规律。结果表明：在不新增设备情况下，单台磨煤机掺烧15%、20%压块牛粪前后，磨煤机电流变化较小；掺烧15%压块牛粪，煤粉细度R200由8.3%增至12.4%，煤粉细度R90由35.8%增至40.0%；掺烧20%压块牛粪，R200由8.3%增至14.4%

R90由35.8%增至54.4%；磨煤机出入口压差变化较大，与给煤量密切相关；全炉掺烧比例2.9%(B磨煤机掺烧15%)和6.4%(B磨煤机掺烧20%)压块牛粪工况下，掺烧前后排烟温度变化均在1.0～2.5℃；全炉掺烧比例7.1%(B、D磨煤机掺烧16.0%)和8.7%(B、C、D磨煤机掺烧15%)压块牛粪工况下，在450 MW和550 MW时，掺烧前后排烟温度分别提高3.3℃和3.6℃，变化较大；在250、450、550 MW工况下，掺烧压块牛粪前后CO质量浓度变化小于5 mg/m

，锅炉热效率下降幅度保持在0.06～0.28百分点；掺烧压块牛粪使得NO

、SO

排放降低；机组2台和3台磨煤机分别掺混15%、20%压块牛粪时，年CO

减排量分别为140 312、210 467 t和160 356、240 534 t。

Abstract

Co-firing biomass in coal-fired plants is considered as one of the important technologies for achieving carbon emission reduction. Based on the 660MW ultra-supercritical lignite coal fired plant in Inner Mongolia

this study conducted the first domestic experiment on co-firing cow manure. Cow manure

is a typical herbaceous biomass. the first domestic large scale coal-cow manure co-combustion experiment in a 660 MW ultra supercritical lignite-fired power unit in Inner Mongolia was carried out. The ability of coal mill to grind biomass and coal mixed fuels was investigated

and the effect of mixing compacted cow manure on the milling performance was analyzed.Moreover

the effects of co-firing compacted cow manure on the combustion characteristics

unburned carbon content in fly ash

boiler efficiency

and pollutant emissions at different loads were studied. The results indicate that

without the addition of new devices

the change in coal mill current before and after co-firing 15% and 20% compacted cow manure with single coal mill changed slightly. With co-firing 15% compacted cow manure and the coal fineness R200 increasing from 8.3% to 12.4%

the R90 increased from 35.8% to 40.0%. With co-firing 20% compacted cow manure and the coal fineness R200 increasing from 8.3% to 14.4%

the R90 increased from 35.8% to 54.4%. The pressure difference between the coal mill inlet and outlet varied significantly and was closely related to the coal feed rate. With the furnace compacted cow manure co-firing ratio of 2.9%(15% co-firing with coal mill B)and 6.4%(20% co-firing with coal mill B)

the changes of exhaust temperature before and after co-firing were both between 1.0～2.5 ℃. With the furnace compacted cow manure co-firing ratio of 7.1%(16.0% co-firing with coal mills B and D) and 8.7%(15% co-firing with coal mills B

and D)

the exhaust temperature before and after cofiring increased by 3.3 ℃ and 3.6 ℃ at 450 MW and 550 MW

respectively

which was significant. At 250 MW

450 MW

and 550 MW loads

the change of CO mass concentration was less than 5 mg/m

and the decrease in boiler thermal efficiency before and after co-firing remained 0.06～0.28 percentage points. Co-firing compacted cow manure can reduce NO

and SO

emissions. When the mixing ratio of compacted cow manure on two and

three coal mills was 15% and 20%

the annual CO

emission reduction would be 140 312

210 467

160 356 and 240 534 tons

respectively.
