1.空氣壓力霧化懸浮燃燒原理 水煤漿與空氣經燃燒器以射流方式進入爐膛，促使煤漿氣流與熾熱煙氣產生強烈混合，水分迅速蒸發；同時水煤漿氣流又受到爐膛四壁和高溫火焰的輻射而將懸浮在氣流中的煤顆粒迅速加熱，水煤漿顆粒獲得了的熱量并達到了的溫度就開始著火燃燒。
其著火熱隨燃料的性質和運行工況的變化而變化，鍋爐負荷低時，爐膛平均煙溫降低，燃燒器區域的煙溫也將降低所以霧化燃燒固態排渣水煤漿鍋爐比較低運行負荷在50%左右 2.流化懸浮高效潔凈燃燒技術原理 將滴狀水煤漿投入燃燒室下部由石英砂和石灰石構成床料的熾熱流化床中，其溫度在850—950℃左右。
水煤漿在熾熱的流化床料的加熱下迅速完成水分析出，揮發分析出并著火燃燒及焦碳燃燒過程在流化狀態下顆粒狀水煤漿團進一步解體為細顆粒被熱煙氣帶出密相區進入懸浮室繼續燃燒在燃燒室出口設有分離回輸裝置被熱煙氣帶出的媒體物料和較大的水煤漿顆粒團被分離器分離、捕捉，通過分離器下部設置的回輸通道返回燃燒室下部密相區，既減少了媒體物料的損失，又實現了水煤漿顆粒團的循環燃燒，從而獲得高的燃燒效率。
此外，低溫燃燒過程，有效的控制了熱力型NOx的形成且由于媒體物料由石英砂與石灰石構成，石灰石在高溫下煅燒生成CaO，CaO與SO2反應進一步生成CaSO4，抑制了SO2的排放，而燃燒裝置的運行溫度是CaO脫硫的很好運行溫度，可有效的減少SO2的排放。
中譯英： 1 Air pressure atomization suspension combustion principle Coal water slurry with air through a burner to jet into the furnace, make coal slurry flow and the hot gases produced strong mixing, rapid evaporation of water; at the same time, coal water slurry flow by furnace walls and the high temperature flame radiation. While suspended in the air in the coal particles are rapidly heated, water coal slurry particles obtained sufficient heat and reaches a certain temperature started burning. Its hot with the fuel properties and operating conditions change, the boiler load is low, the average gas temperature decrease, the burner zone will also reduce the flue gas temperature. Therefore, atomization and combustion for solid slag discharging water coal slurry boiler minimum load in 50% or so.
2 Fluidization suspension combustion technology is high efficiency and clean The drip water coal slurry into the combustion chamber is composed of quartz sand and limestone bed material in fluidized bed of hot, the temperature at 850- 950 ℃. Coal water slurry in the hot fluidized bed material under the heating rapid completion of water precipitation, devolatilization and combustion and coke combustion process. In a state of fluidization granular coal water slurry has further disintegrated into fine particles are the hot flue gas out of the dense phase zone into suspension chamber to burn. In the combustion chamber outlet is provided with a separation of transfusion device. Is the hot flue gas out of media materials and large coal water slurry particle group is separated, capture, through the separator is arranged at the lower part of the back channel returns to the combustion chamber lower dense phase zone, both to reduce the media material loss, but also realize the coal water slurry particle group from circulating combustion, while achieving high combustion efficiency. In addition, low temperature combustion process, effective control of thermal NOx formation. And because the media material from Shi Yingsha and limestone, limestone is calcined at high temperature to generate CaO, CaO and SO2 reaction further generates CaSO4, inhibition of SO2emission and combustion device, the operating temperature is CaO desulfurization optimum operation temperature, can effectively reduce the emission of SO2.
