Delayed coking heating furnace, mechanical coke cleaning

Mechanical coke removal uses a coke removal ball as a coke removal tool, and uses a pump to pump water under high pressure to scrape off the coke layer and salt scale attached to the inner wall of the furnace tube. Compared with traditional coke removal
operation, mechanical coke removal does no harm to the inner wall of the furnace tube, and at the same time, the coke removal is more thorough. The following editor introduces the principle of mechanical decoking in detail
Mechanical decoking uses mechanical methods to connect the entrance and exit of the furnace tube to the decoking engineering vehicle through special pipes. The launcher is made of elastic high-density foamed plastic synthetic resin. It is a bullet-shaped ball with a bullet-like shape and a focus-clearing nail head on its body. The ball is pushed by the water pressure emitted by the equipment (the water pressure is maximum, about normal), and the coke is removed through mechanical friction between the ball and the coke body of the furnace tube.
Coke removal balls are available in various specifications, suitable for furnace tubes or pipes with diameters of ~. When the pipe or furnace tube is completely blocked, cleaning cannot be carried out. The material of the coke-clearing ball is synthetic resin. It is slightly larger than the inner diameter of the pipe when it is manufactured. Because it has good elasticity and a large shrinkage rate (up to %~%), it can be easily passed through. Bend pipe, shaped pipe,
shaped pipe and short diameter bent pipe, etc. The shape of the nail head includes square, semi-circular head file shape, etc. The material used is harder than the scale and softer than the heat pipe. The purpose is not to damage the inner wall surface of the pipe. Generally
the choice of defocusing is based on the material of the heating pipe. Nail head.
