摘　　要：针对生物质成型燃料锅炉高温燃烧引起的排放问题,研制了新型生物质成型燃料真空相变锅炉。该锅炉的燃烧器和热水机组均采用真空夹层,高效换热,有效降低燃烧室的固相燃烧温度;锅炉出口设置烟气二次换热器,减少了热量损失。对其热性能以及排放特性进行检测,结果表明:该锅炉热效率可达90.4%;室外排烟温度降至64℃;烟气中NO质量浓度平均值为145 mg/m^(3),CO质量浓度平均值为195 mg/m^(3),烟尘质量浓度平均值为9.30 mg/m^(3),满足国家对工业锅炉在重点地区及地方的排放要求。A new type of vacuum phase change boiler for biomass forming fuel was developed to address the emission issues caused by high-temperature combustion in biomass briquette fuel boilers.The burner and hot water unit of the boiler both used a vacuum interlayer for efficient heat exchange,effectively reducing the solid-phase combustion temperature in the combustion chamber.The boiler outlet was equipped with a secondary flue gas heat exchanger to reduce heat loss.Its thermal performance and emission characteristics were tested.The results show that the thermal efficiency of the boiler can reach 90.4%;The outdoor smoke exhaust temperature drops to 64℃;The average mass concentration of NO in flue gas is 145 mg/m^(3),the average mass concentration of CO is 195 mg/m^(3),and the averagemass concentration of smoke and dust is 9.30 mg/m,which meets the national emission requirementssfor industrial boilers in key areas and regions.
