Definitions

  • the invention relates to a system equipped with a combustion chamber, e.g. a boiler system or a hot water production system, this system being provided with a duct which serves to discharge the combustion gases and leads to the outside and is ultimately equipped with a draft generator.
  • a combustion chamber e.g. a boiler system or a hot water production system
  • this system being provided with a duct which serves to discharge the combustion gases and leads to the outside and is ultimately equipped with a draft generator.
  • the invention is based on the object of designing the systems mentioned at the outset in such a way that an improved utilization of the thermal energy is possible and also ensures that the pollutants can be removed from the combustion gases.
  • the said channel is arranged horizontally or only at a slight incline, and in addition at least parts of the walls of the channel are designed to heat water or similar heat transfer media.
  • duct sections are preferably provided, which are arranged one above the other, so that the combustion and exhaust gases are guided in an approximately S-shaped manner before they can get outside.
  • Such a design of the exhaust gas ducts has the advantage that extensive use of the thermal energy is possible, index the heat still in the combustion gases is supplied to water or similar heat carriers, which can be achieved by different amounts of water, formation of the duct walls and the like.
  • the horizontal or approximately horizontal arrangement of the channels or channel sections also has the advantage that all important parts are easily accessible and the additional measures required for building construction can be dispensed with.
  • the combustion gases are not tested outdoors at a higher altitude, but rather at a controllable height, which prevents untargeted, uncontrollable distribution of the pollutants, but is also possible because the horizontal or roughly horizontal arrangement of the channels allows the combustion gases to be influenced much better.
  • the channels or channel sections advantageously consist of plate-shaped heat exchangers which can be acted upon with water, but also with thermal oil, for example.
  • the channel sections are preferably selected so that there are three stages for cooling the combustion gases. ., While in the first stage (the combustion chamber facing) of water or the like is heated to about 110 ° C, takes place in the second stage heating to about 60-80 ° C, while in the third stage the combustion gases almost at 3 0 ° C have cooled down and accordingly only a correspondingly slight heating of the water? Or. Like. Can effect. It goes without saying that the water heated in this way in the individual stages must be supplied to suitable consumers.
  • the combustion gases pass through a pipe 1 from the boiler (not shown) - moving in the direction of the arrows 2 - into the channel used to discharge the combustion gases, which consists of three sections A, B and C, one above the other, all of which are arranged horizontally. From section A, the gases pass through a deflection point 3, which is designed like a scoop and can be removed, into section B below and from there into section C located near the ground 4, also via deflection point 5 with a removable scoop 6.
  • Section C leads into an end connector 7, which is equipped with a fan 8 for generating the artificial draft within the channel.
  • a fan 8 for generating the artificial draft within the channel.
  • This device which is equipped with nozzles or the like, is designated by 8 ′.
  • the channel sections A - C consist of double-walled plates 9 with a correspondingly rectangular receiving space 10 for water, but possibly also for other liquid heat carriers. Horizontal plates 11 and plates 12 between them in the edge region are provided in such a way that there is approximately one rectangular channel cross section results when one looks at two plates 11 and two plates 12. It goes without saying that the plates 11, 12 have suitable connections in order to be able to conduct the water or the like from one plate to the other plate; the connecting bends are marked with 13. The inlet is at 14 and the outlet at 15.
  • Sections A - C are separated from each other in terms of piping, so as to create three sections with different temperatures, the section in section A having to produce water temperatures of approximately 110-120 ° C, while the water temperature in the section can be approximately 60-80 ° C .
  • the water temperature in the section C should then be about 3 0 ° C, and then the temperature of the combustion gases in the region of the fan 8 to about be 30 ° C, including the device 8 'contributing. The desired condensations and separations thus occur, so that practically all pollutants can still be collected within the end connector in a device (not shown in more detail).
  • the system according to the invention is preferably intended for outputs over 5000 KW.
