Definitions

  • the invention relates to a heat exchanger for exchanging heat between a gas, such as flue gas, and a fluid comprising:
  • Such a heat exchanger is for example known from US 4407237 .
  • This known heat exchanger has a coil shaped pipe arranged in a vertical, cylindrical flue gas channel.
  • a tube is arranged, which is supplied with a cleaning fluid.
  • the wall of the tube is provided with a plurality of openings such that cleaning fluid can be sprayed radially from the tube onto the coil shaped pipe.
  • the tube is further driven to rotate around the axial axis, such that the spray of cleaning fluid evenly covers the coil shaped pipe.
  • this heat exchanger Besides the complexity of the driven spray tube, this heat exchanger according to the prior art sprays in radial direction onto the coil shaped pipe. As a result, the dust and ash particles are sprayed from the coil shaped tube against the cylindrical wall of the heat exchanger, where the particles could again cake to the wall.
  • condensation could occur on the coil shaped pipe. This condensation will take some of the ash and dust particles along. However, if the fluid needs to be heated to higer temperatures, for example above 60°C, then at least part of the coil shaped pipe will be at such a high temperature, that condensation no longer occurs. At this part of the heat exchanger, dust and ash particles will still accumulate on the coil shaped pipe.
  • a heat exchanger according to the preamble, which is characterized by spraying means arranged above the coil shaped pipe, which spraying means have at least one nozzle directed towards the coil shaped pipe to spray cleaning fluid on the coil shaped pipe.
  • the advantage of arranging the spraying means above the coil shaped pipe is that the water sprayed on top of the upper winding of the pipe will flow along all the other windings taking along the dust and ash particles. The water with the particles can then be collected at the bottom.
  • Another advantage is that the water will have the time during its way along the windings to effectively exchange heat with the flue gas and the fluid within the coil shaped pipe.
  • the spraying means comprise an arm rotatably arranged around the axis of the coil shaped pipe and the at least one nozzle is arranged on the arm distal from the rotation point of the arm.
  • the cleaning fluid can be distributed over the circular top side of the coil shaped pipe.
  • the arm is elongate and extends on both sides of the rotation point of the arm. This ensures that the arm is balanced with respect to the rotation point of the arm.
  • the arm comprises an expansion chamber arranged near the rotation point of the arm and a conduit extending from the expansion chamber to the at least one nozzle.
  • the arm will be arranged within the flow of the flue gas, as the arm is arranged above the coil shaped pipe. As a result the arm will be heated to high temperatures. As soon as cleaning fluid, such as water, enters the arm, the water will be heated and steam will be generated. This steam will propel the water out of the at least one nozzle and will hit the upper winding of the coil shaped pipe at a substantial speed, to achieve a good cleaning action.
  • cleaning fluid such as water
  • Another embodiment of the heat exchanger according to the invention further comprises a cleaning fluid supply line and the arm is rotatably arranged around a free end of the cleaning fluid supply line.
  • the cleaning fluid supply line comprises a valve for intermittently opening and closing the supply line.
  • the valve the supply of cleaning fluid can be activated at certain periods, such that the coil shaped pipe is cleaned at regular intervals.
  • Yet another embodiment of the heat exchanger according to the invention further comprises a drain gutter arranged underneath the rotatable arm and at least extending underneath the rotation point of the arm.
  • any leaking fluid can be directed to a position within the heat exchanger, where the fluid can be beneficial.
  • the leaking fluid can directed to the top of the coil shaped pipe, such that the fluid can contribute to the cleaning action.
  • the tangential direction component of the exiting cleaning fluid will ensure that the arm will rotate and causing the cleaning fluid to be distributed evenly of the coil shaped pipe.
  • Figure 2 shows a variant 20 of the embodiment of figure 1 .
  • the same features have been designated with the same reference signs.
