Definitions
- scraper conveyor of the stoker requires constantly maintenance, as the scraper elements simply are damaged by burning or destroyed by clinkering.
- the document WO-A-89/04 939 discloses a furnace with a scraper conveyor, comprising triangular scraper elements.
- the scraper elements are not, however, protected against overheating
- the invention has for its purpose to provide a stoker of the type described in the introductory part, and by which said problems by simple provisions may be solved.
- the stoker according to the invention furthermore may be provided so that said inlet openings for combustion air in the side walls of the heart are devided into three groups each being connected with separate air inlet channels, namely so that a lowermost group is connected with an air inlet channel for primary combustion air, while middle and upper groups are connected with air inlet channels for propely combustion air, and that - in connection with said air inlet channels - air valve means are present for controlling of the air admittance to the respective groups of inlet openings.
- the scraper elements 30 may be supplied with cooling water, which again may be discharged via upper side openings 44 in the broader discharge pipes 38.
- outwardly open angular recesses 46 are provided, which via air nozzle openings 48 are connected with the air supply pipe 36, so that primary combustion air may be admitted along both sides of the beam 28, when this is reciprocated along the bottom part of the heart, that is under the fuel.
