摘　　要：对燃煤型中小锅炉改烧水煤浆所存在的一些技术问题进行了探讨。分析了炉膛结构对改烧水煤浆的影响 ,阐述了防止结渣和防止结焦以及排渣清灰的措施 ,指出燃煤锅炉改水煤浆后补装氧量计的必要性以及灰渣排放比例的变化对配套除尘器的要求。This paper discusses the technical problems encountered by the transformation of coal fired boilers for burning CWM. It analyzes the influence of the combustion chamber on the burning of CWM. It also proposes the solution alternatives for preventing slagging and getting rid of the ash from the boilers. The author then finds out that it is importance to add oxygen detector in the CWM facilities and the requirements of the changing slag discharging rate on the supporting dust suppressors.
