随着我国技术革新、技术革命运动的广泛开展,在锅炉工作者面前提出了能否根本改变锅炉面貌——成倍地缩小体积及减少金属耗量、提高电厂效率的重要。采用压力燃烧锅炉是彻底技术革命的重要方向之一。当燃料在炉膛内燃烧是在压力下进行时,燃烧大为强化,炉膛的容积热强度可以由一般负压燃烧锅炉0.2×10~6大卡/米~3小时增加到7×10~6大卡/米~3小时,从而可使炉膛体积大大缩小。炉膛体积缩小
With the extensive technological innovation and technical revolution in our country, it is very important for boiler operators to change the appearance of the boiler fundamentally. It is important to reduce the volume and the amount of metal consumption exponentially and improve the efficiency of power plants. The use of pressure-fired boilers is one of the important directions for a complete technological revolution. When the combustion of fuel in the furnace is carried out under pressure, the combustion is greatly enhanced. The volumetric thermal strength of the furnace can be increased from 0.2 × 10 ~ 6 kcal / m ~ 3 hours to 7 × 10 ~ 6 large Card / m ~ 3 hours, which can greatly reduce the size of the furnace. Furnace volume reduced
