A high-temperature pyrolysis incineration apparatus that forces external air to a combustion chamber while burning an incineration processing material injected therein at a high temperature within a combustion chamber is provided. The apparatus includes an air-supply tube disposed at the center of the combustion chamber, a fuel supply pipe installed at an upper edge of the inside of the combustion chamber, a punching plate disposed at the bottom of the combustion chamber, a stirring rod rotatably installed at an upper surface of the punching plate using the air-supply tube as a fixing shaft, a heat recovery device disposed outside of the combustion chamber, and a circulation pipe extending from a lid of the combustion chamber to the outside that returns to a location corresponding to an upper portion of the stirring rod at a wall of the combustion chamber via the inside of the heat recovery device.

A highly efficient indoor heating system and device is described. The device is equipped with an internal chimney, as well as vents that are configured to maximize the draft applied to the flame housed within a stove combustion area. The heater is configured to reach temperatures exceeding 300 degrees Fahrenheit in approximately ten minutes. A gravity fed fuel tube, potentially in communication with a wood pellet hopper, is configured to deliver fuel to the stove of the heater. Heat is distributed throughout the structure of the device, and a convection chamber within the device ensures that heat generated is not quickly lost via exhaust.

A regenerative thermal oxidizer purifies a polluted gas by oxidizing a volatile organic compound (VOC) contained in the polluted gas at a high temperature by using an amount of heat of the polluted gas.
