[0026] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0027] Reference Figures 1 to 8A hydrogen alcohol heating furnace includes an organic body 1. The organic body 1 includes a furnace 2 disposed within the organic body 1, a heat exchange tube 3 disposed within the furnace 2, a burner 4 disposed at the bottom of the furnace 2 and capable of heating the heat exchange tube 3, an oil supply module 5 connected to the burner 4 and used to provide hydrogen alcohol fuel, a flue gas condenser 6 disposed within the organic body 1 and used to collect the flue gas discharged from the furnace 2, a flue gas outlet pipe 7 disposed between the furnace 2 and the flue gas condenser 6 and connecting the two, and a flue gas exhaust mechanism 8 disposed on the flue gas condenser 6 and capable of discharging the flue gas in the flue gas condenser 6 to the outside. Hydrogen alcohol fuel refers to a clean liquid fuel with methanol, ethanol, or alcohol-based mixed fuels as the main components, rich in hydrogen elements in its molecular structure, and usable as a liquid hydrogen energy carrier. The hydrogen alcohol fuel described herein specifically refers to alcohol-based fuel suitable for combustion in heating furnaces. In the name, "hydrogen" represents the fuel's high hydrogen content and hydrogen energy utilization properties, and "alcohol" represents that the fuel's main component is an alcohol-like substance. Furnace 2 is the core space for combustion reaction and primary heat exchange, providing a sealed combustion environment for burner 4; heat exchange tube 3 directly absorbs high-temperature radiant heat and convective heat in furnace 2, achieving efficient conversion of heat energy into water medium; burner 4 provides atomization, ignition, and stable combustion conditions for hydrogen alcohol fuel, ensuring complete combustion of fuel; oil supply module 5 continuously and stably delivers hydrogen alcohol fuel to meet continuous heating needs; flue gas condenser 6 cools and condenses high-temperature flue gas, recovering sensible and latent heat in the flue gas, further improving system energy efficiency; flue gas outlet pipe 7 achieves sealed connection between furnace 2 and flue gas condenser 6, guiding the directional flow of flue gas; exhaust mechanism 8 provides power for flue gas flow, maintains negative pressure in furnace 2, and ensures stable combustion. Furthermore, an outlet 11 and an inlet 12 are provided on the side wall of the unit 1. The outlet of the heat exchange tube 3 is connected to the outlet 11, while the inlet of the heat exchange tube 3 passes through the flue gas condenser 6 and is connected to the inlet 12. In this way, cold water enters the heat exchange tube 3 through the inlet 12 to absorb heat, and hot water is output from the outlet 11 to the external heating terminal, thus forming a closed loop for heating. In this way, the utilization rate of thermal energy is improved through the two-stage heat exchange structure of furnace 2 heat exchange and flue gas condensation.

[0028] In this design, the heat exchange tube 3 is spiral in shape and coils along the inner wall of the furnace 2. This design maximizes the residence time of the water flow in the furnace 2, increases its heat exchange area and heat exchange path, thereby fully absorbing the high-temperature radiant heat and convective heat in the furnace 2 and further improving the heat exchange efficiency.

[0029] In this design, the flue gas condenser 6 includes a flue gas chamber 61 and condenser tubes 62 disposed within the flue gas chamber 61. The outlet of the condenser tubes 62 is connected to the inlet of the heat exchange tubes 3, the inlet of the condenser tubes 62 is connected to the water inlet 12, and the outlet of the heat exchange tubes 3 is connected to the water outlet 11. In this way, cold water first enters the condenser tubes 62 to absorb the waste heat from the flue gas for preheating. The preheated water then enters the heat exchange tubes 3 for secondary heating, forming a two-stage series heat exchange mode of preheating and main heating. This fully recovers the sensible heat and latent heat released by the condensation of water vapor in the high-temperature flue gas, reduces the exhaust temperature, and improves the overall heating efficiency. Simultaneously, low-temperature exhaust is more environmentally friendly and reduces heat waste.

[0030] Furthermore, the exterior of the body 1 is provided with a hot water circulation system, which is connected to the condenser pipe 62 and the heat exchange pipe 3. Specifically, the hot water circulation system includes a hot water circulation pipeline, as well as a water distributor, water collector, dirt remover, water supply pipeline, pressure regulating device and circulating water pump installed on the hot water circulation pipeline.

[0031] In this design, the smoke box 61 is U-shaped, with an inlet 611 connected to the smoke outlet pipe 7 and an outlet 612 connected to the smoke exhaust mechanism 8 on the upper sides of both ends. This U-shaped structure extends the residence time of the flue gas within the smoke box 61, allowing for sufficient heat exchange between the flue gas and the condenser tube 62, thus improving the condensation effect. The condenser tube 62 is spiral-finned. Specifically, the condenser tube 62 is inserted from the top of one end of the smoke box 61, then downwards to the bottom of the same end, then extends out from the bottom of one end and into the bottom of the other end, then upwards to the top of the other end and connects with the heat exchange tube 3. This design increases the heat exchange area of ​​the condenser tube 62, improving the heat exchange efficiency between the flue gas and the water inside the tube.

[0032] In this design, a condensate drain outlet 13 is provided at the bottom of the body 1, and a condensate outlet 613 is provided at the bottom of the smoke box 61. A condensate drain pipe 9 is provided between the condensate outlet 613 and the condensate drain outlet 13 to connect the two, thereby draining the condensate outside the body 1 and preventing the smoke box 61 from being corroded or the flue gas from being obstructed due to the accumulation of condensate, thus ensuring the long-term stable operation of the equipment.

[0033] In this design, the top of the body 1 is provided with a flue gas outlet 14, and the flue gas exhaust mechanism 8 includes an induced draft fan 81 mounted on the smoke box 61 and located at the flue gas outlet 612, and a flue gas exhaust pipe 82 mounted on the induced draft fan 81 and connected to the flue gas outlet 14. Preferably, the control module can control the start, stop, and speed of the induced draft fan 81 according to the working state of the burner 4 to ensure negative pressure in the furnace 2 and smooth exhaust of flue gas.

[0034] In this design, the side wall of the engine body 1 is provided with an oil inlet 15 and an oil return port 16. The oil supply module 5 includes an oil inlet pipe 51 located inside the engine body 1 and connected to the oil inlet 15, an oil pump 52 located at the other end of the oil inlet pipe 51, an oil supply line 53 located on the oil pump 52 and connected to the burner 4, and an oil return line 54 located inside the engine body 1 and connected to the oil return port 16. The other end of the oil return line 54 is connected to the oil supply line 53. This ensures a stable oil supply pressure through the oil pump 52, guaranteeing that the hydrogen alcohol fuel is delivered to the burner 4 at a set flow rate. Furthermore, the oil return line 54 returns excess fuel from the oil supply line 53, stabilizing the oil supply pressure and preventing unstable combustion caused by pressure fluctuations.

[0035] Furthermore, the machine body 1 is externally equipped with an oil supply and return system, which is connected to the oil inlet pipe 51 and the oil return pipe 54. Specifically, the oil supply and return system includes an oil tank connected to the oil inlet pipe 51 and the oil return pipe 54, as well as a control valve and an oil filter located at the oil outlet of the oil tank.

[0036] In this design, the burner 4 includes a fixed base 41 at the bottom of the furnace 2, a burner head 42 on the fixed base 41, an oil injector 43 on the fixed base 41 and located below the burner head 42, and an ignition needle 44 on the fixed base 41 and located between the burner head 42 and the oil injector 43. The oil injector 43 is connected to the oil supply line 53. A blower connection seat 45 is provided at the bottom of the fixed base 41, and a blower 46 is provided on the blower connection seat 45. The oil injector 43 atomizes the hydrogen alcohol fuel into fine oil droplets, which are then ignited by a high-voltage electric spark generated by the ignition needle 44, rapidly igniting the atomized fuel and forming a stable flame on the burner head 42. During this process, the blower 46 delivers sufficient combustion air into the furnace 2, ensuring thorough mixing of fuel and air, further improving combustion efficiency and reducing pollutant emissions.

[0037] In this design, a stove opening 17 is provided on the upper side of the body 1 and at the top of the furnace 2. The stove opening 17 is covered with a cover plate 18. Opening the cover plate 18 allows the residual heat at the top of the furnace 2 to be used for auxiliary operations such as boiling water and cooking, thus expanding the functionality of the equipment. Closing the cover plate 18 can seal the furnace 2, reduce heat loss, and ensure heating efficiency, thereby achieving dual use for heating and cooking.

[0038] In this scheme, the side wall of the furnace 2 is provided with a heat insulation layer. The heat insulation layer is made of heat insulation material with high temperature resistance and low thermal conductivity. It is wrapped around the outer wall of the furnace 2 to reduce the heat loss of the furnace 2 to the inner cavity of the body 1, maintain the high temperature environment of the furnace 2, and improve the heat exchange efficiency.

[0039] In this design, the machine body 1 is equipped with an electronic control module to control its operation. This module includes an LCD screen, a control board, and a switching power supply. The LCD screen can display parameters such as water temperature, combustion status, and operating mode in real time, facilitating intuitive user monitoring. The control board integrates control logic for ignition, fuel supply, blower, and circulation pump, enabling functions such as automatic ignition, constant temperature control, fault alarm, and overload protection. Furthermore, to facilitate transport, the machine body 1 is equipped with omnidirectional casters at its bottom that feature self-locking design.
