Abstract

Thermal equipment characterised in that the hearth is arranged according to the axis of the boiler, forming a corridor which allows continuous evacuation of the ashes and clinker (3) to an exit chamber (4) with shutter (5). A burner, which comprises an adjustable fuel feed from a storage hopper (7) or from a transfer chamber fed by an endless screw (8) or cyclone, a hearth nozzle (9) with adjustable primary (10) and secondary (11) air inlets, a device which is controllable by push-button (12), which ensures removal of ash from the nozzle outlet (13) and the automatic continuous clearing of the hearth, and lastly an electronic control block (14).

Description

La présente invention concerne un équipement autonome automatique pour combustion rationnelle des produits et déchets de biomasse et des sous-produits de recriblage du charbon caractérisé par Une chaudière (I) en fonte ou en acier spécialement conçue comportant à la construction ou à l'adaptation :The present invention relates to an automatic autonomous equipment for rational combustion of biomass products and waste and coal sifting by-products, characterized by a specially designed boiler (I) made of cast iron or steel, comprising in construction or adaptation:

un foyer sole (2) formant couloir disposé suivant l'axe avant arrière de la chaudière pour permettre une évacuation continue des cendres et des machefers (3) vers un sas (4) de sortie avec obturateur (5)a hearth hearth (2) forming a corridor arranged along the rear front axis of the boiler to allow a continuous evacuation of the ashes and the machefers (3) towards an airlock (4) with outlet shutter (5)

Un brûleur automatique spécialement conçu pour obtenir un rendement maximum par la combustion complète des gaz obtenus au premier stade l'ignition.An automatic burner specially designed to obtain maximum efficiency by the complete combustion of the gases obtained in the first stage of ignition.

Ce brûleur se compose :

  • a/ d'une alimentation en combustible à partir d'une trémie réserve (7) ou d'un sas de transfert alimenté par vis sans fin (8) ou cyclone. Cette alimentation est réglable suivant les caractéristiques du combustible.
  • b/ une tuyère (9) de foyer avec arrivée d'air primaire (10) et secondaire (II) de débits définis en fonction des caractéristiques du combustible.
  • c/ un dispositif à poussoir (12) assure le décrassage de la sortie de tuyère (13) et le décendrage automatique du foyer en continu. Ce dispositif est commandé suivant les caractéristiques du combustible.
  • d/ un bloc électronique (14) suivant les caractéristiques du combustible assure toutes les commandes de fonctionnement.
This burner consists of:
  • a / a fuel supply from a reserve hopper (7) or a transfer airlock supplied by worm (8) or cyclone. This supply is adjustable according to the characteristics of the fuel.
  • b / a furnace nozzle (9) with primary (10) and secondary (II) air intake with flow rates defined according to the characteristics of the fuel.
  • c / a pusher device (12) ensures the cleaning of the nozzle outlet (13) and the automatic ash removal continuously. This device is controlled according to the characteristics of the fuel.
  • d / an electronic unit (14) according to the characteristics of the fuel ensures all the operating commands.
