Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Please refer to shown in Fig. 1, the utility model provides a kind of numerical control auto-coal-fired boiler, comprise burning furnace chamber, be positioned at above burning furnace chamber automatically fill out device for coal, be positioned at burning furnace chamber and automatically fill out device for coal side heat exchange body of heater, be positioned at smokejack 100 above heat exchange body of heater, described automatically fill out device for coal comprise coal store 1 that bottom is provided with funnel, be positioned at coal store 1 funnel below to barrel 2, be positioned to the screw extrusion bar 3 of barrel, the drive motors 4 of delivering coal that links with screw extrusion bar 3; Described burning furnace chamber surrounding arranges water jacket 5, and centre is combustion chamber 6, and arrange heat exchanger tube 7 in the middle of combustion chamber, be provided with inlet box 8 below combustion chamber, top, combustion chamber is provided with into coal swing gate 9, and side, combustion chamber is provided with the gas outlet be communicated with heat exchange body of heater; Described giving to arrange discharging opening below barrel 2 and enters coal swing gate 9 and be communicated with; Described heat exchange lower portion of furnace body is connected with the gas outlet of side, combustion chamber 6, is provided with cleaning door 10 below heat exchange body of heater, and heat exchange body of heater surrounding is water jacket 5, and centre arranges heat exchanger tube 7, and heat exchange body of heater upper end is communicated with smokejack 100; Be provided with blast pipe 11 outside described inlet box 8, blast pipe 11 rear end is connected with air blast 12, and described water jacket is communicated with heating of house heat-exchanger rig by pipeline with heat exchanger tube.Side, described combustion chamber is provided with burning peep hole 13 and slag cleaning peep hole 14, and described recuperative furnace side side is provided with Heat Room cleaning eye 15.Described air blast 12 and drive motors 4 of delivering coal are frequency control motor, temperature sensor is provided with in described water jacket, described air blast is all connected with a controller 16 by cable with deliver coal drive motors and temperature sensor, and described controller is provided with numerical control chip module.
