water-cooled furnace wall

Thermal Deviation of water wall outlet piping caused by bad furnace firing condition can cause considerable temperature difference on the working media of inlet piping which is introduced to furnace roof inlet header.

由于炉膛燃烧不理想导致水冷壁出口管的热偏差，使进入顶棚进口集箱的引入管的工质产生了较大的温差。

Under the conditions of full-circumferential heating and half-circumferential heating, the heat transfer and pressure drop characteristics of internally ribbed tube with the diameter of φ 28 × 6 mm used in the furnace water wall of 600 MW supercritical sliding pressure operation once-through boiler was studied experimentally.

本文在全周加热和单侧加热的条件下，对600MW超临界变压运行直流锅炉水冷壁φ28×6mm内螺纹管进行了传热与阻力特性的试验研究。

High Temperature Corrosion of Water Wall for Tangentially Fired Boiler Furnace

大容量锅炉四角切圆燃烧时的水冷壁管高温腐蚀问题

As for the radiation heating surface of the furnace, take the effective coefficient of the thermal water wall as the fouling characteristic parameter, and then establish the overall monitoring model of a slagging heating surface based on the lumped parameter model and furnace exit gas temperature.

然后，对炉膛辐射受热面，以水冷壁热有效系数作为受热面的灰污特征参数，基于集总参数模型和炉膛出口烟温，建立了炉膛辐射受热面结渣的整体监测模型。

In order to reduce the erosion of water-wall, large furnace sectional area should be selected by boiler works, and the power plant should select the coal caloricity close to the designed for use.

对于循环流化床锅炉，炉膛截面积选择的大小影响炉内循环物料的速度，即水冷壁的磨损速度，燃料的发热量影响炉内循环物料的浓度。
