Definitions

  • This invention relates to a bonfire furnace, and more particularly to a safe, easy-to-control bonfire generating device using biofuels.
  • the bonfire is an ancient tradition of human beings and is loved by people in many countries. So far, the way to set up a bonfire is basically to put wood, coal, charcoal on the ground or in a container and then ignite.
  • This traditional bonfire discharge method brings the following major problems. First, security issues. The sparks or flames produced by the burning dance with the wind, and it is easy to ignite other objects or burn people or other animals. Especially when natural wood or coal produces a deflagration in combustion, the situation is even more dangerous. Second, the flame control problem. Ignition and flameout in this type of bonfire discharge often take a long time.
  • Wood and coal are not easily ignited by ordinary ignition devices such as lighters, igniters, etc., and flameouts can only be used in the form of water quenching or natural burning. Water quenching requires a sufficient amount of water to be prepared, and natural burning often requires personnel to wait. Either way, the efficiency of controlling the flame is low. In addition, since the flame is completely affected by the natural wind, the bonfire cannot be discharged at all when the wind is large, especially when there is a large gust. Third, environmental impact issues. Conventional discharge methods generate smoke over a long period of time from the start of combustion to full combustion, which has a negative impact on the health and environment of the surrounding people.
  • the main technical problem to be solved by the present invention is to provide a bonfire furnace which does not generate Mars flying out of the furnace body, and the flame does not dance with the wind in the height range of the person, which can bring great safety to the bonfire. .
  • Another technical problem to be solved by the present invention is to provide a simmering furnace which can only ignite or completely extinguish the igniting or extinguishing in a short period of time by the user pushing the button.
  • Another technical problem to be solved by the present invention is to provide a simmering furnace which can be used normally even when the wind is continuous or the gust wind is large.
  • Another technical problem to be solved by the present invention is to provide a simmering furnace which has a small amount of soot and ash, and which does not leave a stain which is difficult to remove on the ground after burning.
  • Another technical problem to be solved by the present invention is to provide a bonfire furnace capable of forming a flame exceeding the height of a person and capable of forming a spectacular bonfire flame scene.
  • Another technical problem to be solved by the present invention is to provide a bonfire furnace which is easy to move, that is, it is convenient to move within a short distance by a person to move, and it is also convenient to use a vehicle for long-distance movement.
  • the present invention provides a bonfire furnace using biomass fuel particles and including A body that can be placed on the ground, the body includes a combustion box and an auxiliary equipment box.
  • the combustion box includes a bottom surface that can be laid flat on the ground, a side that extends upward along the periphery of the bottom surface, a top surface that is connected to the upper edge of the side surface and opposite the bottom surface, and a switchable door is provided on the side.
  • the burner has a fuel rack plate, a side panel extending upwardly along the periphery of the fuel rack plate, a top plate above the side plate and opposite the fuel rack plate, a blast zone located below the fuel shelf plate, and a side panel at a combustion zone enclosed above the fuel shelf.
  • a ventilation hole is formed on one side of the auxiliary equipment box on the blast zone, and a front opening is formed on the opposite side of the air supply hole.
  • a flame tube leading to the combustion zone is fixed above the combustion zone on the top plate, and a plurality of air inlet holes are opened in the periphery of the flame cylinder.
  • the auxiliary equipment box houses a fuel delivery mechanism and electrical equipment.
  • the fuel delivery mechanism includes a hopper, a delivery barrel having one end communicating with the outlet below the hopper and the other end extending into the combustion zone, and a rotatable fuel auger rod accommodated in the delivery cylinder.
  • the electrical equipment includes a blower that communicates with the air supply aperture, a feed motor that drives the fuel auger, a power supply, and a power switch.
  • a flame portion is also mounted above the top surface of the body, and the flame portion is a flame rising space formed by the high temperature resistant glass surrounding the flame tube.
  • the beneficial effects of the present invention are first, since the combustion process is mainly completed in the burner, and the blast-type combustion can greatly increase the sufficiency of combustion, and Mars composed of tiny fuel particles is not easily separated from the burner. Then, the flame is splashed to the outside through the longer flame portion; at the same time, the flame jumps in the flame portion and is not easily affected by the wind, so the safety of the natural bonfire is greatly improved.
  • the high temperature ignition rod and blower can quickly burn the fuel to produce the desired flame; and after the user closes the furnace, the blower can continue to work for a period of time, so that the combustion chamber The fuel can burn out quickly. This greatly increases the efficiency of the bonfire generation and extinction.
  • biomass fuel pellets are used in the furnace.
  • Biomass fuel itself is more flammable, less smog, and less ash than large-density wood and coal.
  • Granular biomass fuels further reduce ignition time, smoke and ash emissions, especially during initial ignition and extinction.
  • the ash in the furnace is concentrated in the burner, which is easy to clean by opening the door; the combustion in the furnace is also concentrated in the burner, and no hard-to-clear smudges are formed on the ground.
  • the presence of the air inlet hole on the flame tube allows the outside air to enter and flow at a high speed in the flame portion, causing a flame that is much higher than the natural burning bonfire height to form a spectacular bonfire scene.
  • the stove is easy to move compared to the traditional campfire. It is possible to select a more suitable burning location by personnel movement within a short distance, and also to move long distances by means of vehicles.
