The utility model relates to a streamline flue pipe cover which is used for flue pipes and exhaust cylinders.

一种用于烟筒和排气筒的流线型烟筒罩。

Air pressure protection device: When the fan doesn't work, or the flue pipe is blocked, or the air pressure is too high, combustion will automatically stop.

风压过大保护装置：当风机故障、烟道堵赛、风压过大时，燃烧自动停止。

The equipment pipe and air and flue gas ducts etc. supplied by the contractor shall be made in maximum allowable dimensions to reduce the fabrication on site.

承包商供应的设备、管道、烟风道等必须做成容许的最大尺寸以减少现场加工和安装的工作量。

Into the tail flue of fly ash due to the low temperature, has a certain hardness, so primary heating surface with flue gas exhaust pipe, the wear and tear on the wall.

蒸汽锅炉进入尾部烟道的飞灰由于温度较低，具有一定的硬度，因此随烟气初级受热面排管时，会对管壁产生磨损作用。

The heat pipe failure, lower heating air temperature, higher flue gas emission of the furnace in operation are analyzed and improvement measures are suggested.

对实际运行中存在的热管失效、热空气温度偏低、排烟温度偏高等问题进行了分析，并提出了相应的改进措施。
