介绍操作蒸汽发作器的步骤
Introduce the steps of operating the steam spreader
1、燃气蒸汽发作器在水汽体系方面,给水在加热器中加热到必定温度,经给水管道进入省煤器,进一步加热以后送入锅筒,与锅水混合后沿下降管下行至水冷壁进口集箱。水在水冷壁管内吸收炉膛辐射热构成汽水混合物经上升管到达锅筒中,由汽水别离设备使水、汽别离。
1.In terms of water vapor system, feed water heating in the heater to the temperature, the feed water pipe into the economizer, after further heat into drum, mixes with pan of water along the drop next to the water wall tube inlet header. The water is absorbed into the tube of water wall and the heat of the furnace is absorbed into the boiler tube. The water and steam are removed from the water.
2、别离出来的饱满蒸汽由锅筒上部流往过热器,持续吸热成为450℃的过热蒸汽,然后送往汽轮机。在焚烧和烟风体系方面,送风机将空气送入空气预热器加热到必定温度。在磨煤机中被磨成必定细度的煤粉,由来自空气预热器的一部分热空气带着经焚烧器喷入炉膛。
2.By separation of full steam drum upper stream to the superheater, continue endothermic become 450 ℃ of superheated steam, and then sent to the steam turbine. In the incineration and smoke system, the air blower sends air into the air preheater to be heated to a certain temperature. Pulverized coal pulverized in a coal mill, which is sprayed into the furnace by a portion of hot air from the air preheater.
3、燃气蒸汽发作器汽化更安静,削减水的带着,蒸发面大。蒸汽更干,质量高,削减管壁的结垢。蒸汽发作器紊流火焰逆流向下构成涡流,加强了在循环混合,进步了热功率。蒸汽发作器的养护非常简单:火焰侧传热肋片上下均有孔道接通,便于直接调查和整理;排污完全查看便利:排污孔坐落低侧,即便于排污,又不易被阻塞。由顶部调查孔可直接全部调查炉膛顶板和水侧壁。

3.Vaporization of steam paroxysm is quieter, with water cutting and evaporation. Steam is more dry, high quality and reduces the scale of the pipe wall. The turbulent flame of the steam paroxysm is formed eddy current, strengthening the mixing of the cycle and improving the thermal power. The maintenance of the steam trap is simple: there are holes in the hot side of the flame, making it easier to investigate and organize directly. Blow-down is completely convenient: the blow-down hole sits on a low side, even if it is not obstructed. The top hole can directly investigate the roof and water side wall of the furnace.
