Abstract
The invention relates to a burner which is suitable for utilizing heat energy of hot exhaust in a flue or a strong exhaust pipe so as to increase combustion heat value of coal or gas in the burner. The burner comprises a combustion chamber and the flue which is connected with the combustion chamber and is used for waste gas exhaust. A heat exchange pipe is disposed in the flue. An air inlet of the heat exchange pipe is used for inhaling new air outside the flue. An air outlet of the heat exchange pipe is connected with a new air inlet of the combustion chamber. By the burner, the new air outside the flue is exchanged into hot air by the aid of the heat exchange pipe, the exchanged hot air is delivered into the combustion chamber and combined and burned with the coal or the gas, combustion heat value of the coal or the gas is increased, resource utilization rate is enhanced, and energy conservation and emission reduction are realized. The heat exchange pipe is in a vertical tube type. A spiral air deflector is distributed spirally and axially on the inner wall of the flue. A vertical tube is inserted into the spiral air deflector axially, so that heat exchange stroke between high temperature waste gas in the flue and the heat exchange pipe is prolonged and heat exchange effect is enhanced.
Description
Technical field
The present invention relates to the technical field of energy-saving combustion furnace, specifically a kind of combustion furnace that is suitable for the new air of flue heat exchange to send back to combustion chamber, specifically can be applicable to coal furnace, gas furnace and gas heater etc.
Background technology
Existing combustion furnace, as: coal furnace, gas furnace and gas heater etc., the hot waste gas of generation is directly discharged from flue or forced-ventilated pipe; And these hot waste gas often have higher temperature, how to utilize the heat energy of these hot waste gas and improve coal in described combustion furnace or the combustion heat value of gas, to improve resource utilization, be the technical problem that this area will solve.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of simple in structure, combustion furnace of being suitable for utilizing the heat energy of the hot waste gas in flue or forced-ventilated pipe and improving the combustion heat value of coal or gas etc. in described combustion furnace.
For solving the problems of the technologies described above, combustion furnace provided by the invention comprises: the flue for combustion gas that He Yugai combustion chamber, combustion chamber is connected; In described flue, be provided with heat exchanger tube, the air intake of this heat exchanger tube is for sucking the new air outside described flue, and the gas outlet of this heat exchanger tube is connected with the new air intake of described combustion chamber.The knot such as new air and coal or the gas combining combustion entering from the new air intake of this combustion chamber.
As preferred scheme, described heat exchanger tube is vertical pipe type heat exchanger tube, is beneficial to improve the speed of the new air of suction.
Further, for convenience of assembling, the air intake of described heat exchanger tube extends the top exterior walls of described flue, and the bottom outer wall of described flue is extended in the gas outlet of heat exchanger tube.
Further, for lengthening the heat exchange stroke of high-temp waste gas and described heat exchanger tube, improve heat transfer effect, in described flue, be provided with the spiral aviation baffle distributing along this flue inwall axial screw; Standpipe in heat exchanger tube axially interts in this spiral aviation baffle.
Further, in order to ensure heat transfer effect time, improve toxic emission speed, the pitch of described spiral aviation baffle strengthens from bottom to top gradually from described flue.Because the EGT that is close to described flue bottom is higher than flue top, therefore, by less the pitch setting of the spiral aviation baffle of contiguous described flue bottom, be beneficial to raising heat transfer effect.By larger the pitch setting of the spiral aviation baffle at contiguous described flue top, be beneficial to and improve toxic emission speed.
The present invention has positive effect with respect to prior art: combustion furnace of the present invention arranges heat exchanger tube in flue, heat exchanger tube will be hot-air from the new air heat-exchange outside flue, then send into combustion chamber and coal or gas mixed combustion, improve the combustion heat value of coal or gas etc., improve resource utilization, be suitable for energy-saving and emission-reduction.
Brief description of the drawings
Fig. 1 is the structural representation of combustion furnace in embodiment 1;
Fig. 2 is that the structure of the vertical pipe type heat exchanger tube in the flue in Fig. 1 is launched schematic diagram.
Detailed description of the invention
Embodiment 1
See Fig. 1 to 2, the combustion furnace 1 of the present embodiment, comprising: combustion chamber 2 and the flue 3 for combustion gas being connected with this combustion chamber 2; In described flue 3, be provided with heat exchanger tube 4, the air intake 41 of this heat exchanger tube 4 is for sucking the new air outside described flue 3, and the gas outlet 42 of this heat exchanger tube 4 is connected with the new air intake of described combustion chamber 2 through air exhauster 5.
When work, heat exchanger tube 4 will be hot-air from the new air heat-exchange outside flue 3, then sends into combustion chamber 2 and coal or gas mixed combustion, has improved the combustion heat value of coal or gas, improves resource utilization, is suitable for energy-saving and emission-reduction.
Described heat exchanger tube 4 is vertical pipe type heat exchanger tube, is beneficial to improve the speed of the new air of suction.
The air intake 41 of described heat exchanger tube 4 extends the top exterior walls of described flue 3, and the bottom outer wall of described flue 3 is extended in the gas outlet of heat exchanger tube 4.
For lengthening the heat exchange stroke of high-temp waste gas and described heat exchanger tube 4, improve heat transfer effect, in described flue 3, be provided with the spiral aviation baffle 8 distributing along this flue inwall axial screw; Standpipe in heat exchanger tube 4 axially interts in this spiral aviation baffle 8.
In order to ensure heat transfer effect time, improve toxic emission speed, the pitch of described spiral aviation baffle 8 strengthens from bottom to top gradually from described flue.Because the EGT of the bottom of contiguous described flue 3 is higher than the top of flue 3, therefore, by less the pitch setting of the spiral aviation baffle 8 of the bottom of contiguous described flue 3, be beneficial to raising heat transfer effect.By larger the pitch setting of the spiral aviation baffle 8 at the top of contiguous described flue 3, be beneficial to and improve toxic emission speed, thereby taken into account toxic emission and heat exchange efficiency; Toxic emission is unobstructed, can guarantee that the new air of heat can enter combustion chamber 2 fast, than the efficiency of combustion that improves described coal or gas.
Obviously, above-described embodiment is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also giving exhaustive to all embodiments.And these belong to apparent variation that spirit of the present invention extended out or variation still among protection scope of the present invention.
