FIELD: heating. ^ SUBSTANCE: invention is intended for water heating and may be used in heat and power engineering. Boiler plant is provided with housing where furnace chamber with grate mesh, afterburner and heat-exchanging unit are installed. Housing walls are comprised of top horizontal brick wall, bottom horizontal brick wall, first outer vertical end wall, second outer vertical end wall and vertical shielding wall mounted in the middle of housing. Shielding wall splits housing hollow into furnace chamber and afterburner. By its upper surface, this wall is installed with clearance with regard to top wall. Plant is provided with the device to supply refined wood fuel. It is represented as silo with convergent bottom. Top guiding plate is fixed to silo bottom. Together with bottom guiding plate and side walls, top guiding plate form channel for fuel flowing from silo to furnace chamber. Plate is fixed to silo bottom, which form rectangular housing together with bottom plate and side walls. Rectangular piston connected to eccentric flywheel is installed inside rectangular housing. Grate mesh is in the form of panel hinged to upper end of rack. Lower end of rack is fixed to lower wall and main grate-bars are fixed to panel by supports. Rods of supports are inserted into one of grate bars bridges opening. Vertical plate supporting immovable grate bar, is installed on lower plate. Rotary grate bar is installed between fixed grate bar and shielding wall. Channel for air supply duct connection for burning and fuel gasification is located between the first end wall and panel rack. Channel for air supply duct connection for coke afterburning is located between fixed grate bar and vertical plate. Injector is situated in afterburner. It is connected with air supply duct when inflammable gases are re-burnt. Pipes with circulating water connected to inner pipes of heat-exchanging unit are installed in after afterburning chamber. ^ EFFECT: widening of functional possibilities of boiler plant and optimizing fuel burning and fuel gas afterburning processes. ^ 3 dwg |
