Definitions

  • the present invention relates to a process for continuous dry removal of bottom ash as well as to the relevant apparatus for carrying out said process.
  • the combustion produces an ash residue of two fractions, namely fly ash carried by smoke and mainly picked up by the electrostatic filters provided for protecting the environment and bottom ash gathering on the boiler bottom, which must be removed.
  • the presently used boilers at their bottom have a water tank adapted to cool ash so as to allow the required removal with mechanical or hydraulic systems and also to give tightness so as to prevent false air .[.to enter.]. .Iadd.from entering .Iaddend.the boiler.
  • the mixture consisting of water, ash and unburnt coal is sent to a plant for separating and recovering water, while the dry residue, not having an economical industrial use, is sent to .Iadd.a .Iaddend.dump and creates considerable environmental problems.
  • the present invention removes these drawbacks and provides for a dry removal of bottom ash, being based on the novel principle of using a conveyor belt to remove said ash.
  • a conveyor belt to remove said ash.
  • the steel belt conveyor is made so as to withstand mechanical stress due to ash impact and thermal stress due to burner radiation and high temperature of the removed ash.
  • the load bearing function and the driving function are assigned to two different but joined elements; the load bearing function to a set of steel plates suitably shaped and partially overlapped so as to form a continuous trough; and the driving function to a net-like wired belt made of high tensile steel.
  • Each plate is individually fixed to the belt by a set of rivets or bolts which are connected with crosspieces inserted in the links of said belt.
  • This system allows free expansion of the plates in every direction according to temperature variations in order to avoid permanent set.
  • the steel wired belt is friction actuated by a cylindrical driving drum and it is stretched by a jockey drum on which a tensioning system is acting.
  • the driving system.Iadd., .Iaddend.based on friction and tension, allows .[.that also.]. the wired belt .[.may.]. .Iadd.to .Iaddend.have free expansion in any direction avoiding permanent set.
  • the load bearing run of the belt is supported by smooth rollers while the return run is supported by cast iron or steel wheels.
  • Roller shafts protrude outside the container box, so that they can be supported by bearings arranged in a cool area. Between the shafts and the corresponding holes made in the box there are heat resistant seals preventing air entrance and gas passage, but allowing a sliding movement of the shafts due to expansion.
  • a cyclically operated valve limiting or preventing entrance of cool air may be applied downstream the area of ash discharge from the apparatus.
  • a quantity of air controlled by the above system may be delivered counter-currently to the direction of ash discharge. In this way the heat yielded to air by ash and by the combustion of the unburnt matter on the belt, is brought again into the boiler so as to increase its efficiency.
  • FIG. 1 is a lateral general view of an embodiment of the apparatus according to the present invention.
  • FIG. 2 is a vertical sectional view of the apparatus, taken in the left-hand portion along line X--X and in the right-hand portion along line Y--Y of FIG. 1;
  • FIG. 3 is a detailed view of the passage of the conveyor belt on the driving drum
  • FIG. 4 is a detailed bottom view of a portion of the conveyor belt
  • FIG. 5 is a sectional view taken along line Z--Z of FIG. 4, showing the structure of the conveyor belt.
  • FIG. 6 is a partially sectioned elevational view, showing the detail of the support particularly designed for the rollers bearing the conveyor belt.
  • the apparatus substantially comprises a steel conveyor belt consisting of a plurality of steel plates 1 suitably shaped and partially overlapping so as to form a continuous trough.
  • Each plate 1 is provided with lateral boards 11 and some plates have also transverse dams 12 for dividing the trough into sections, so as to avoid .[.that.]. .Iadd.a condition in which .Iaddend.the material slides back in the inclined stretches.
  • these plates 1 have the load bearing function, while the driving function is effected by a high strength steel wired belt 2.
  • Each plate 1 is individually fixed to belt 2 by bolts 8 with relevant nut 10, which however may be replaced by rivets or other equivalent fastners, which are connected to crosspieces 9 suitably inserted in the links of said wired belt 2.
  • This open system allows free expansion of plates 1 in any direction when temperature changes, so as to avoid permanent set.
  • the steel wired belt 2 is friction actuated by a cylindrical driving drum 7 and it is tensioned by a jockey drum 13 on which a tensioning device is acting, said device being not illustrated in greater detail as it is well known in the conveyor technique.
  • This driving system based on friction and tension, .Iadd.also .Iaddend.allows .[.that also.]. the wired belt 2 .[.way.]. .Iadd.to .Iaddend.undergo free expansion in any direction, so as to avoid permanent set.
  • the load bearing run of the belt is supported by smooth rollers 3, while the lower return run is supported by cast iron or steel wheels 4.
  • Shafts 14 of smooth rollers 3 protrude outside a steel containing box 15, which is applied at the boiler bottom, so that ash is falling on the conveyor belt enclosed therein and said shafts 14 may be supported outside the hot environment by bearings 16, thus arranged in a cool area and supported by specially designed supports 5.
  • a guide and adjustment pin 18 protrudes from a hole made in support 5 and provided with a sealing gasket 19.
  • a cyclically operated valve 60 is located downstream of (that is, below) the area of ash discharge from the boiler, between the load bearing run and the return run of belt 2. Valve 60 may be operated to deliver air to the boiler countercurrently to the direction of ash discharge from the boiler. .Iaddend.
