Definitions

  • the present invention relates to boilers comprising solid waste burning units; which, in wet systems, consist of stationary and mobile sliding bearings with tubular system water conduits and wherein, in waterless system, the stationary sliding bearings comprise tubular system water conduits and the mobile bearings are preferably made of heat resistant metal or ceramics.
  • Wet system coal burning systems are also called “stoker”. It is ensured that the coal is provided with air and that it burns more efficiently by introducing air to the coal ignited within the chamber, and having a worker frequently mixing the coal.
  • the metal surface which is heated as a result of the burning, transfers its heat to the water and thereby enables the water to be heated and vapor to be obtained. In this method, burning the coal with low efficiency and employment of a worker for the mixing raise the costs.

  • Sliding bearings are designed as steps within the burning unit from upper part to lower part.
  • the upper sliding bearing is stationary, the sliding bearing therebelow is mobile, the one below the latter is a stationary sliding bearing. That is, one mobile sliding bearing is arranged in between two stationary sliding bearings.
  • the coal coming from the funnel is lead to the upper stationary sliding bearing by the help of a piston; the coal ignited here is enflamed by means of the air coming from the fan through the blowing holes, and falls down to the lower mobile sliding bearing as a result of the pushing of the piston.
  • the coal which continues to burn therein slides from the mobile sliding bearing as a result of the pushing of the piston and falls down to the lower stationary sliding bearing and performs coal feeding from the upper stationary mobile bearing during its return movement.

  • the metal balls which prevent the friction of mobile steps are affected by high values of heat and get deformed, and for that reason, mobile steps frequently fail.
  • Garbage, medical waste and similar solid wastes are disposed of via burning by the waterless system in burning chambers whose walls are coated with high heat resistant ceramics or heat resistant refractories. Burning chambers are heavy, bulky and their transportation and assembly are difficult and expensive. Transport, storage and burning of the medical wastes from hospitals and similar medical care institutions require an extensive organization and care.
