    The invention relates to power engineering, and more specifically to solid-fuel high-sulfur boiler plants.
    The purpose of the invention is to provide a more complete and efficient cleaning of gases from sulfur.
    FIG. 1 shows a schematic representation of the proposed boiler plant, a section; FIG. 2 — an embodiment of a boiler installation suspended on a frame; FIG. 3 shows section A-A in FIG. 2 {in FIG. 4 shows an installation with a furnace having a head of a gas outlet pipe, a section of the boiler plant body at the level of the above pipes {Fig. Figure 5 is a plan view of a frame located around a boiler on which centrifugal dust collectors and cyclones are installed for a furnace that has four gas inlets.
    The boiler plant on solid fuel contains the furnace 1 boiling
    layer placed on the gas distribution grid 2, blown by the primary air supplied by the fan 3 and the air duct 4 and preheated in the air heater 5. A gas supply manifold 6 is located above the gas distribution grid 2, and a boiler 7 with tubular walls 8 is located above the gas distribution grid 2 zany with a fire chamber. The furnace 1 is made in the form of a gasifier, and the boiler 7 is separated from it by a transverse gas-tight partition 9 formed by the bends of the vertical pipes of the walls 8 of the boiler. The furnace 1 and the boiler 7 are connected to each other by a connecting gas pipeline 10, equipped with a centrifugal separator 11 and a device for cleaning gases from
    sulfur, and at the base of the boiler is located the burner 12, to which the gas line 13 and the nozzle 14 of the oncoming air supply are connected. The device for purification of gases from sulfur is made in the form of a U-shaped section 15 of a connecting gas pipeline 10 located behind the centrifugal separator 11 and containing a zone 16 for the introduction of a desulfurizing agent and installed after the U-shaped section 15 of a cyclone 17 to capture particles formed after the reaction and desulfurization. To the air pipe 4 is connected to the air pipe 18, permits
    If necessary, supply a certain amount of heated air directly to the furnace 1. Boiler 7 can be made suspended on frame 19 and equipped with power supply columns 20, and centrifugal dust collector 11 and cyclone 17 are rigidly connected to these columns by means of a bracket 21 to form a single node suspended on the frame 19 at the same level as the boiler.
    The furnace 1 can have four gas exhaust pipes 22, each of which has a connecting gas line 23 with its centrifugal separator 24 and cyclone 25, which are mounted on a frame 26 located around the boiler and rigidly connected to its power supply columns 20 to form a single unit suspended on frame 19 at the same level as the cat ..
    Boiler installation on solid fuel works as follows.
    Solid fuel, such as coal, enters the furnace 1 through the fuel supply pipe 6 to the gas distribution grill 2, through which the primary air supplied by the fan 3 through the air duct 4 and preheated in the air heater 5 is blown.
    The gas produced during combustion of fuel passes into the upper compartment of the furnace 1, where it is cooled to a temperature that is favorable for the desulfurization reaction and enters the connecting gas line 10 and then into the centrifugal separator 11, where the gas is cleaned from particles of the fluidized bed, which are unburned fuel residues and ashes. Dust-free gas is cleaned from sulfur. To do this, the gas after centrifugal lance piping 11 enters the zone 1 of the introduction of the desulfurization agent, which are CO-based substances, such as dolomite, limestone or chalk. The desulfurization reaction proceeds with the passage of gas along section 15 of the connecting gas pipeline 10, which is made U-shaped and has a length sufficient to ensure the maximum possible desulfurization3
    the The gas then enters the cyclone 17, which provides for the cleaning of the pelvis from particles formed as a result of the desulfurization reaction,

    such as CaS, CaO and CO Ca; The gas free of dust and sulfur escapes from the cyclone 17 through a gas pipeline 13, which is connected to the burner 12 located at the base of the boiler 7. At the same time, the secondary combustion air is supplied to the burner 12 through the nozzle 14. Bent gases generated during the combustion of gas in the burner, at the outlet from the boiler 7, serve to heat the heating tail surfaces, and then enter the air heater 5 to heat the air.
    The air duct 18 connected to the air duct 4 allows, if necessary, to supply some air directly to the furnace 1, due to which it is possible to change the amount of secondary air supplied to the burner 12, in the case of the unit not operating at full capacity.
    The boiler 7 is suspended on a frame 19 formed by four sinks, on the upper part of which horizontal beams are mounted, holding crossbars, on which all components of the boiler (drum, manifolds, walls) are hung, and also the bracket 21, on which the centrifugal pusher 11 and cyclone 17 and which is attached
    14
    to frame 19 with the aid of power supply columns 20, of which there are at least two in the installation. Water enters the upper part of the columns 20 through pipes:; from the boiler drum; from the lower part of these columns, water is supplied through pipes to the base of the boiler. The power supply columns 20, along which the boiler water flows, have approximately the same temperature as the tubular walls 8 of the boiler, are suspended on the same frame 19 as the boiler, and therefore, they also experience the same temperature lengthening. From this it follows that the centrifugal section 11, under any circumstances, is located exactly opposite, the outlet of the furnace 1, and the cyclone 17 opposite the burner 12.
    If there is a chaff in the firebox 1 of the gas exhaust pipes 22, each of them is connected to its own connecting gas line 23, which goes to the corresponding burner. Each connecting gas line 23 contains its own centrifugal separator 24 and a cyclone 25 for removing particles generated by the desulfurization reaction. Four centrifugal dust collectors 24 and four cicons 25 are mounted on a frame 26 located around the boiler and rigidly connected with the columns 20 of the boiler’s power to form a single shaft suspended on the frame 19 at the same level as the boiler.
