Abstract：Origin and current situation of civil coal in China was discussed.The effects of characteristics of civil coal types and forms and combustion technologies on the pollutant emission were analyzed.Based on research status,the civilian coal clean utilization technologies were summarized from 3 aspects:pre-combustion processing,combustion technology and post-processing.The recommendations of civil coal clean utilization are proposed.The briquette with high sulfur retention rate should be developed based on the mechanism and influencing factors of sulfur retention.The biomass briquette with low cost,good mechanical performance and good applicability should be developed.The replacement of raw coal by briquette will be benefit to the environment.The developing of efficient,clean and low cost civil cooking stoves should be emphasized to improve the thermal efficiency of civil coal and achieve clean combustion.The civilian use of coal-fired flue gas purification system should be realized.
