Description

Technical Field

[0001] This invention belongs to the field of environmentally friendly bio-oil combustion furnace technology, specifically relating to a method for increasing the combustion heat of an environmentally friendly bio-oil combustion furnace. Background Technology

[0002] Environmentally friendly bio-oil, primarily referring to environmentally friendly bio-ethanol oil, is a flammable liquid produced by fertilizer plants manufacturing nitrogen and ammonia through combined alcohol production equipment. It is formulated with additives such as calorific value enhancers, modifiers, combustion improvers, oxidants, stabilizers, smoke suppressants, and flavoring agents in specific proportions. Environmentally friendly bio-oil is characterized by being pressure-free, non-explosive, non-toxic, and having an auto-ignition point of 385℃, making it safe and reliable to use. Even if accidental leakage and fire occur due to improper use, it can be extinguished with water, unlike diesel or liquefied petroleum gas (LPG) fires which can cause significant losses. Furthermore, accidentally leaked environmentally friendly bio-oil is water-soluble or dries naturally, unlike diesel or LPG which pollute the environment and pose safety hazards. Environmentally friendly bio-oil is a renewable energy source. Its use is smokeless, odorless, pollution-free, residue-free, and leaves no black residue on cooking pots, resulting in cleanliness and hygiene. The carbon monoxide produced during combustion is lower than that of diesel and LPG, which is beneficial to the health of kitchen staff and the cleanliness of the kitchen environment, making it an environmentally friendly energy source. Environmentally friendly oil has a high calorific value and strong heat output, reaching 8300 kcal / kg, which is slightly lower than diesel. However, the amount of environmentally friendly oil used can be increased to achieve the calorific value of diesel or liquefied petroleum gas.

[0003] The annular burner core, composed of a tubular outer ring and metal wire mesh, not only facilitates the use of environmentally friendly bio-oil, but its all-metal construction also ensures long-term durability and even flame distribution. However, in practical use, users still desire a higher maximum combustion power from the annular burner core. Currently, this is typically addressed by increasing the diameter of the ring and using multiple annular burners. However, increasing the ring diameter inevitably enlarges the cross-sectional area of ​​the bio-oil burner, making an excessively large burner inconvenient to use. Using multiple annular burners also makes adjusting the flame intensity difficult. Users often desire the ability to adjust the flame intensity according to their own preferences.

[0004] Therefore, it is necessary to design a method to increase the combustion heat of environmentally friendly bio-oil combustion furnaces. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention employs a novel environmentally friendly bio-oil combustion furnace, which increases the maximum combustion power of the annular furnace core without increasing its diameter or number.

[0019] In the past, when a ring-shaped furnace core was placed directly in a conventional combustion furnace, only the fuel on the outer metal mesh could burn fully. Although the fuel on the inner metal mesh could also come into contact with some air for combustion, the combustion effect was significantly poor due to insufficient ventilation. Furthermore, since the metal mesh furnace core layer was located inside the tubular outer ring layer, only the upper part of the outer metal mesh of the metal mesh furnace core layer could fully contact the air, while the lower part of the outer metal mesh was attached to the tubular outer ring layer. In this invention, the outer side of the furnace core contacts the inner side of the fire regulating ring. To ensure a smooth contact surface, the tubular outer ring layer must be located outside the metal mesh furnace core layer.

[0020] Because the furnace body of this invention is open from top to bottom, and a ventilation hole is provided at the center of the bottom of the furnace cover, and furnace cover support feet are provided at the four corners of the furnace cover, sufficient oxygen can come from below to the inside of the furnace core, thereby making the environmentally friendly bio-oil burn more completely.

[0021] The fuel used in this invention can also be other mineral oils, bio-oils, or environmentally friendly oils with a flash point higher than 70.

[0022] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the figures. Attached Figure Description
