Problems solved by technology

[0003] In the prior art, if the coal in the heating furnace is not fully burned, a large amount of harmful and flammable and explosive flue gases such as CO and SO2 will be produced, and these flue gases will flow away directly from the flue. On the one hand, when the flue gas is directly After being discharged to the outside, it will cause environmental pollution; on the other hand, when the flue gas flows directly from the flue, a large amount of heat in the furnace will be taken away, causing more heat loss and reducing the thermal efficiency of the heating furnace

Abstract

The invention discloses a secondary combustion high-efficiency heating furnace. The secondary combustion high-efficiency heating furnace includes a furnace body, a combustion chamber, a furnace mouth,a furnace grate, an ash storage chamber, and a fume exhaust pipeline communicating with the combustion chamber, wherein the top of the combustion chamber is provided with a fire outlet; a secondary combustion air supply system is arranged at the fire outlet; a flue-gas-guide fire distributing device is arranged on the furnace mouth and above the secondary combustion air supply system; a coal inlet is arranged at the front portion of the furnace body; a coal adding reverse smoke preventing sealing device is arranged outside the coal inlet in a hinge mode; a communicating heat exchange water jacket is arranged on the combustion chamber and the fume exhaust pipeline; the fume exhaust pipeline is provided with a high-efficiency heat collecting system communicating with the heat exchange waterjacket; the outer wall of the fume exhaust pipeline is provided with a flue ash cleaning device corresponding to the high-efficiency heat collecting system; the lower portion of the rear part of thefurnace body is provided with an explosion-proof valve communicating with the heat transfer water jacket; and the heat transfer water jacket is connected with a heat supply terminal. The secondary combustion high-efficiency heating furnace has the advantages of simple structure and reasonable design, and the utilization rate of heat and the thermal efficiency of the heating furnace are improved.

Description

technical field [0001] The invention relates to the technical field of heating furnace equipment, in particular to a secondary combustion high-efficiency heating furnace. Background technique [0002] Most of the northern rural households use coal-fired heating stoves for domestic water heating in winter, which can be used not only for cooking, but also for heating with heating. It is very convenient to use and has a high penetration rate. With the improvement of living standards, people have higher and higher performance requirements for coal-fired heating stoves for plumbing, that is, they should seek a safe coal-saving, pollution-free, high thermal efficiency, and convenient household use stoves to meet the current civil plumbing requirements. Market demand for coal-fired heating appliances. [0003] In the prior art, after the coal in the heating furnace is not fully burned, a large amount of harmful and flammable and explosive flue gas such as CO and SO will be produce...
