Description

Wood burning apparatus {Wood combustor}

The present invention is intended to obtain the benefits of burning firewood and solid wood firewood, such as firewood boilers, firewood fans, dryers, firewood stoves, heat exchanger coupled to or built into the combustion device and the combustion apparatus such as firewood will be. More specifically, the combustion chamber that burns solid fuel such as firewood in a group of combustors insulates the main part where the flame touches so as not to be directly exposed to the outside air or the heat medium, thereby bringing the combustion chamber to a high temperature, and the cross-sectional phenomenon of the combustion chamber becomes narrower from top to bottom. It is inclined at the lower end to lose shape so that the combustion point is concentrated, and the combustion induction path is formed so that the flame is formed at the lower part of the combustion chamber and guided to the rear side. Secondary air inlet pipe is installed inside, so that high-temperature flame and unburned gas are secondary burned, and higher temperature is formed through the insulated vertical combustion furnace, and the temperature of the vertical burner reaches the high temperature above the ignition point. The thermal combustion bridge which burns the high temperature heat formed in this way, Heat exchange with heating water or air, and exhaust gas cooled by heat through exhaust pipe to maximize thermal efficiency, improve combustion efficiency with complete combustion such as firewood, and reduce the input amount drastically. The present invention relates to a firewood burner that has reduced costs and improved smoke generation.

Most of the firewood combustors such as the firewood boilers used in the prior art have a structure in which the heat of combustion during combustion is largely heat exchanged in the body of the combustion chamber or the water chamber in contact with the combustion chamber for the purpose of heat exchange, or by installing a communication inside the boiler, As the water in the chamber can be absorbed as much as possible, it is quickly discharged. As a result, it is difficult to form a high temperature in the combustion chamber, and condensation or wood vinegar is accumulated inside the contact with the outside air or the communication with the chamber. There was a large amount of wood vinegar or blockage of communication. Due to this, there is a large amount of unburned gas smoke, and it is not able to sufficiently express the amount of heat that wood has. Therefore, the combustion efficiency is low, and the consumption of firewood as a fuel is large, and smoke generation has remained.

The present invention has been made to solve the above problems, the object of the present invention is to completely burn the firewood, such as firewood of the solid to express the maximum amount of heat that the firewood and the like to use the high-temperature exhaust gas or In addition to a heating device using hot water heated through a heat exchanger, it is possible to drastically reduce the number of inputs and inputs of firewood and the like, thereby reducing fuel costs and devising means without smoke. Specifically, it is possible to collect the fire point when the fire is burning, and to control not to be burned suddenly, and to create a high temperature environment above the ignition point or to collect flames in the ship research through the unburned gas smoke. Finding a means for ignition or ignition to increase the combustion efficiency and to find a method of high heat exchange efficiency to increase the thermal efficiency.

In a cuboid or cylindrical boiler, a combustion device, etc., the firewood combustion device or the boiler body has a water chamber that encloses the whole or a part, and inside and outside the body, the left and right widths become narrower and a front and rear train barrier wall is formed. Between the wall and the body is filled with high quality, high heat resistant insulation of 50mm or more. This is for the combustion chamber and the combustion point portion to easily reach a high temperature so as not to lose the heat of combustion to the surrounding water chamber or the outside. In addition, a large number of grooved tubes are arranged on the inclined surface of the lower part of the heat shield plate of the combustion chamber so that the flames ignited from the lower part can be led directly to the flame receptacle and the vertical combustion furnace without going upward. It induces concentration and forms a flame path, so that the high temperature of the fire chamber and the flame does not spread to the upper part, but only the lower part is burned, thereby preventing overheating of the combustion chamber, and the ease of introducing new firewood and the firewood of the upper part after combustion. This is to make the form of supplying fuel automatically by falling down naturally. And the charcoal base is welded and installed at the bottom of the c-type iron plate with the bottom part open to form a long front and back, and the fresh air supply and flame in the front and back direction between the charcoal and charcoal base and the lower space of the charcoal base itself. It has an unburned gas movement path, and at the lower part of the rear part, there is an opening widening from the upper part of the upper part to the lower part so that the flames are concentrated there. By installing the insulated vertical combustion tube on top of it, the hot flame and high heat gas generated by the concentration of the combustion point caused by the hopper type combustion chamber without reaching the heat or the heat medium to reach the upper part by the vertical combustion, In this process, a high temperature unburned gas (smoke) above the ignition point is created to ignite or spontaneously ignite the flame. This leads to complete combustion, which results in all the heat contained in the firewood. In addition, by forming a heat exchanger with several layers inside at the top of the vertical combustion furnace, it is possible to increase the residence time of heat and maximize the heat transfer area to construct a firewood burner with improved thermal efficiency.

As described above, the burning of firewood and other fires eliminates the generation of smoke, which is beneficial to the surrounding environment, and the complete combustion effect without generating smoke increases combustion efficiency and significantly reduces fuel input. It is reduced and evaporated with water generated in the combustion process to be discharged to the outside to maintain cleanliness and to reduce the adsorption of combustion products such as communication and heat exchanger to improve the convenience of cleaning and management.

The high temperature of the combustion chamber shortens the combustion time, which is advantageous for large-capacity design, and reduces the number of fuel inputs, thus providing the convenience of overall management, and the burning of firewood in the combustion chamber by flame induction. It is easy to input firewood without any inconvenience during combustion, and it is possible to maintain combustion time for a long time according to the control method of air supply.The design of unconstrained structure enables the heat exchanger to maximize the thermal efficiency. Along with fire prevention, it is possible to create economic hot air.
