A kind of vertical boiler with air preheater described in the utility model, overall structure is simple, installation and easy for operation, good stability, reliability is high.Use a kind of vertical boiler with air preheater described in the utility model, can effectively utilize the waste-heat boiler of flue gas used to wind, reduce exhaust gas temperature, reached the effect of saving the energy.The beneficial effects of the utility model are: by the simple transformation of vertical boiler, utilized fume afterheat, be also conducive to the after-flame of hearth combustion and coal, improved boiler efficiency, reached the effect of saving the energy.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of a kind of vertical boiler with air preheater described in the utility model.1-air preheater, 2-hot air duct, 3-controllable register, 4-trunnion, 5-water-cooled grate, 6-slag notch, 7-lower furnace door, 8-upper furnace door, 9-upper furnace, 10-body of heater, 11-funnel base.
Detailed description of the invention
Referring now to accompanying drawing 1, be described as follows: a kind of vertical boiler with air preheater described in the utility model, includes air preheater 1, hot air duct 2, controllable register 3, trunnion 4, water-cooled grate 5, slag notch 6, lower furnace door 7, upper furnace door 8, upper furnace 9, body of heater 10 and funnel base 11 in conjunction with the embodiments.Body of heater 10 is main components of a kind of vertical boiler with air preheater described in the utility model, entirety is the version of furnace cupola, the lower end of body of heater 10 arranges body of heater pedestal, a side at body of heater pedestal is provided with slag notch 6, on body of heater pedestal, a side of body of heater 10 is provided with lower furnace door 7, in body of heater 10 on lower furnace door 7, be provided with the water-cooled grate 5 of inclination form, above water-cooled grate 5, it is upper furnace 9, one side of upper furnace 9 is set to upper furnace door 8, the opposite side of upper furnace 9 is set to trunnion 4, trunnion 4 is connected with the lower end of hot air duct 2, the upper end of hot air duct 2 is connected to air preheater 1, at the lower position of hot air duct 2, be provided with controllable register 3.The middle position, upper end of body of heater 10, is connected with funnel base 11, and the upper end of funnel base 11 is used for connecting chimney, and a side of funnel base 11 is connected with air preheater 1.A kind of vertical boiler with air preheater described in the utility model, is to be provided with air preheater 1 at the Increasing exports of the impact tube of vertical boiler, and the upper end of air preheater 1 is air intake, and the lower end of air preheater 1 connects hot air duct 2.By air preheater 1, cold air is heated into hot blast from impact tube flue gas out, hot blast regulates after air quantity through controllable register 3 by hot air duct 2, in trunnion 4 enters the top upper furnace 9 of water-cooled grate 5, participate in burning, owing to having reduced exhaust gas temperature, boiler efficiency can increase, and simultaneously owing to being hot blast to wind, is also conducive to the after-flame of hearth combustion and coal.A kind of vertical boiler with air preheater described in the utility model, has increased air preheater in impact tube exit, and the top that air preheater hot blast out enters water-cooled grate by the trunnion of hot air duct, boiler body participates in coal burning.Controllable register can regulate hot blast air quantity to adapt to different load.Air preheater, hot air duct and trunnion form airtight passage, cold air is heated and sends into burner hearth.A kind of vertical boiler with air preheater described in the utility model, to install air preheater 1 additional in the exit of vertical boiler impact tube, in order to reduce resistance and to be conducive to heat exchange, installation, adopt heat-pipe air preheater, flue gas is heated into hot blast by heat pipe by cold air, and due to the draft of chimney, hot blast is through hot air duct 2, controllable register 3, enter the upper space of water-cooled grate 5 by the trunnion 4 on boiler body, participate in the burning of coal.In the use, decline because exhaust gas temperature reduces rear draft, therefore, for maintaining the draft of gravity-flow ventilation, should increase the height of chimney.When normal combustion, upper furnace door, lower furnace door, slag notch should be closed, and with hot blast burning, in the time that load is larger, deficiency in draught, just can consider to open fire door, increases intake as far as possible.The intake of hot blast can, according to load condition, be adjusted by controllable register.A kind of vertical boiler with air preheater described in the utility model, overall structure is simple, installation and easy for operation, good stability, reliability is high.Use a kind of vertical boiler with air preheater described in the utility model, can effectively utilize the waste-heat boiler of flue gas used to wind, reduce exhaust gas temperature, reached the effect of saving the energy.The beneficial effects of the utility model are: by the simple transformation of vertical boiler, utilized fume afterheat, be also conducive to the after-flame of hearth combustion and coal, improved boiler efficiency, reached the effect of saving the energy.
