A pyrolysis furnace having a heating chamber which surrounds a cylindrical pyrolysis chamber. The heating chamber is assembled from an upper part and a lower part, which can be joined. Each part of the heating chamber is provided with two rows of heating elements, which are arranged along the length of the housing of the heating chamber symmetrically relative to a vertical plane passing through the axis of the pyrolysis chamber. The heating elements are in the form of units, containing at least one flameless gas burner. The heating elements in the upper part of the heating chamber are arranged in a checkerboard fashion relative to the heating elements in the lower part. The furnace relates to power generation and the environment and is intended for the thermal processing of solid and free-flowing materials, particularly in processes for the pyrolysis of solid carbon-containing materials, including municipal and domestic waste.

To provide a pyrolysis apparatus capable of pyrolyzing an object to be treated without releasing exhaust gas to the atmosphere. This pyrolysis apparatus includes: a treatment furnace having a pyrolysis section where an object to be treated is subjected to pyrolysis on a grate; a purification water tank retaining water and having a gas pool formed in an upper part thereof; a primary purification tank connected to the upper part of the purification water tank, in which water is jetted toward exhaust gas flowing in from an upper part of the treatment furnace through a gas flue; a piping through which gas is taken up from the gas pool of the purification water tank and returned to the primary purification tank; a secondary purification tank connected to the upper part of the purification water tank, in which water is jetted toward the gas taken up from the gas pool of the purification water tank; and a return piping through which the gas having passed the secondary purification tank is fed into the treatment furnace.

Provided is a sealing structure for a horizontal rotary pyrolysis kiln. A movable heat-insulation sealing ring is disposed such that a heat-insulation cavity is formed between the movable heat-insulation sealing ring and a flexible sealing mechanism. The heat-insulation cavity can effectively block the heat dissipated from a kiln tail cover and a kiln tail, thereby effectively reducing the ambient temperature of the flexible sealing mechanism in the heat-insulation cavity. In this way, the service life of the flexible sealing mechanism is prolonged, and the effectiveness of sealing is thus ensured.

A thermal processing apparatus and a thermal processing method where the vessel with interconnected chambers in which the solid material is thermally processed is suspended in a heat exchange medium while it is rotated, which reduces the energy to rotate the vessel, increases heat transfer surface area, increases the turbulence of the heat exchange medium around the vessel and improves the movement of solid particles relative to each other and relative to the heat exchange surface. These features combine to increase the heat transfer rates within a compact vessel size.

A blast furnace includes: a blast furnace body; raw material charging means for charging raw material into the blast furnace body; hot air blowing means for blowing hot air into the blast furnace body; a drying apparatus etc. for evaporating moisture in low-grade coal; a dry distillation apparatus etc. for carbonizing dried coal; a cooling apparatus etc. for cooling carbonized coal; a pulverization apparatus etc. for pulverizing the carbonized coal cooled by the cooling apparatus; a storage tank for storing powdered coal; a nitrogen gas supply source, a conveyor line and a cyclone separator etc. for conveying the powdered coal pulverized by the pulverization apparatus to the inside of the storage tank by generating a gas flow with the nitrogen gas; and an injection lance etc. for feeding the powdered coal inside the storage tank to hot air that is blown into the blast furnace body.
