    This invention relates to a boiler installation for the combustion of solid fuels, for example forest waste material in the form of e.g. bark and or chips, peat pellets, coal etc., which installation comprises a furnace located in connection to a heat medium portion and a grate means located in the furnace, which grate means feeds fuel from a fuel charge opening through the furnace while the fuel is being combusted, from which furnace the flue gases flow to the heat medium portion and continue to a chimney, and at least one intake for controlled supply of combustion air in the form of at least primary and secondary combustion air. In order to improve the efficiency degree of such boiler installations and to render possible efficient and complete combustion of forest waste material and other biologic fuels, which may have a high moisture content, the rear portion of the grate means (4) of the boiler installation, seen in the direction of movement, is located outside of the furnace space (1) proper but connected thereto for forming a zone in connection to the charge opening (5 for a certain drying of the fuel before it is fed into the furnace (1) by the grate, and comprises transverse dogs (9) running on a grate plane for advancing the fuel through the furnace (1), which grate plane is located above means (25,26) for the supply of the primary combustion air from below to the fuel, and below the air intakes (29) for the secondary combustion air.

    This invention relates to fuel combustion and can be used in thermal power plants.
    The purpose of the invention is to increase efficiency by increasing the efficiency of combustion.
    FIG. Figure 1 shows a device for burning solid fuels, longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 - node I in FIG. 1; in fig. 4 shows a section BB in FIG. 3; in fig. 5 shows a section B-B in FIG. 3; in fig. 6 is a view of FIG. 5 in FIG. 7 is a view of D in FIG. five.
    A device for burning solid fuels, mainly woodworking waste in the form of bark or chips, and other biological materials, mainly peat, contains a furnace with a loading chamber 1, a combustion chamber 2 and a discharge chamber 3 in which the grate 4 is located. The loading chamber 1 is equipped bore 5 for supplying fuel. The combustion chamber 2 is connected to the chimney 6 and is provided with heating surfaces 7, a device 8 for introducing primary air located under the grate 4 and nozzles 9 of secondary air located under the grate 4. Nozzles 9 are connected to the ducts 10. The grate 4 is made in the form of stationary grate pcs 11 with holes 12, under
    which accommodate scrapers 13 mounted with the possibility of translational movement from the loading chamber 1 to the discharge chamber 3. The scrapers 13 are fixed on endless chains 14 that move along two rollers 15 and 16. The roller 16 is driven and provided with a drive 17. Shaft rotation speed 16 adjusts-with automatically depending on the operating conditions. The grate plates П are provided with U-shaped elements 18, placed above the openings 12 and resting on the plates 11 with the help of spacer elements 19, which can be made in the form of long bars. The upper branch of chains 14 is located in guide pairs 20 made in the side walls of chambers I-3. The grate 11 is supported by its edges on plates 21 mounted between the upper and lower branches of the scraper chains 14. A device 8 for introducing primary air is placed in plates 21 and has dampers 22 which are intended to direct the primary air to the heating parts of the grill 4, as well as To regulate the flow of primary air. The combustion chamber 2 in front of the heating surfaces 7 has a pinch 23 and there are placed nozzles 24 for inlet of tertiary air connected to the ducts 25. The ducts 10 and 25 are connected to the channels 26, which are 313
    puppies outside the firebox or in the walls of the 2-combustion chamber. To adjust the amount of fuel coming from the loading chamber 1 into the combustion chamber 2, there is placed a gate 27 between them. In the lower part of the discharge chamber 3 a screw 28 is placed for unloading ash with a drive 29. Before the discharge chamber 3 under the grate 4, the flap 30, and at the end of the grate a chute is installed for transporting ash into the screw 28. Scrapers 13, grate 11 and U-shaped elements 18 can be made of silicon carbide. The walls of chamber 2 of combustion can be made of sintered and luminium blocks.
    A device for burning solid fuels works as follows.
    The fuel is continuously and automatically through the opening 5 enters the charging chamber 1, is picked up by scrapers 13 and moves through the grate moves through the combustion chamber 2, where it is dried, gasified and burned. Ash and slag enter the discharge chamber 3 and the screw 28 is led out of the furnace. The flap 30 adjusts the height of the fuel bed in the combustion chamber 2. The flue gases enter the upper part of the combustion chamber 2, where they are mixed with secondary and tertiary air, which ensures the afterburning of unburned fuel, is cooled by the heating surfaces 7 and through the chimney from the device.
