Description

Multi-Stage Combustion Curing Heater with Multiple Combustion Walls The present invention relates to a curing stove, and more specifically, to a curing stove equipped with multiple combustion walls to limit the combustion area during initial combustion, thereby preventing over-combustion and enabling stable combustion. Concrete does not undergo chemical reactions at temperatures below 5℃, so curing does not occur. Therefore, during the winter season when temperatures are low, after pouring the concrete, a heater or similar device is installed in the center of the structure to maintain a constant indoor temperature, thereby preventing the moisture inside the concrete from freezing and allowing for smooth chemical reactions within the concrete to proceed with curing. In this process, it is necessary to supply heat uniformly because the amount of heat lost due to concrete curing must be calculated mathematically and scientifically to compensate for the lost heat. Therefore, rather than simply using a stove that generates a lot of heat, a stove that minimizes heat loss and maintains stable heat for more than 12 hours is effective for curing. Meanwhile, curing stoves used for curing concrete during the winter are mostly fabricated on-site. The exterior of the stove is formed by processing steel containers found around the site, such as drums, and fuel like firewood or pellets is inserted. The stove utilizes a combustion method where ignition is applied from the top, causing the fuel to gradually burn and travel downwards. However, since these conventional curing stoves burn firewood or pellets by igniting them in a drum with an open top, incomplete combustion occurs due to overburning during the first 1 to 2 hours after ignition due to the characteristics of wood fuel, resulting in smoke and soot. This leads to fuel waste and harm to the working environment. FIG. 1 is a perspective view illustrating the external configuration of a curing stove according to the present invention.
