The present invention is intended to provide a hybrid combustion apparatus using the pyrolysis of water and combustion air, in which a combustion chamber is defined by a double wall and divided into a primary combustion chamber configured to combust waste and a secondary combustion chamber configured to combust exhaust gas, and the size (diameter) of a combustion unit through which waste is configured to be different from that of the combustion chamber in which a flame is located, so that combustion temperature is further increased by introducing air, so that heated due to proximity to a flame, as combustion air, combustible waste is combusted at an ultrahigh temperature by pyrolyzing water and combustion air by means of a high combustion temperature, and so that complete combustion is achieved by increasing the time for which a flame stays within the combustion chamber, thereby discharging clean exhaust gas.

A biomass gasification system for producing aqueous or water gases after biomass has been carbonized is disclosed. Temperatures of a thermal decomposition and gasification furnace can be quickly and uniformly stabilized with smaller thermal loss. Reaction residuals after thermal decomposition and gasification are prevented from adhering on the inner surface of the system. The biomass gasification system comprises: a main body, a first cylindrical member, a first cut-out member, a first cylinder accommodating therein a first screw conveyor, a second cylindrical member, a second cut-out member, a second cylinder accommodating therein a second screw conveyor. The first cylinder is so constructed that it penetrates the main body, the first cylindrical member and the first cut-out member in an axial direction. The first screw conveyor, the second screw conveyor and the second cut-out member have a plurality of gasifying agent ports, respectively.

A gasifier may include a chamber wall defining a gasification chamber configured to allow gasification of feedstock material. The gasifier may also include an ash grate disposed in the gasification chamber. The gasifier may further include a rotary crusher disposed in the gasification chamber above the ash grate. The rotary crusher may include at least one crushing element. The rotary crusher may be configured to break apart, between the at least one crushing element and an opposing surface, the feedstock material responsive to rotation of the rotary crusher.

The present invention relates to a method for incineration of combustible waste during the manufacture of cement clinker where cement raw meal is preheated and calcined in a preheater (1) with a calciner (3), burned into clinker in a kiln (5) and cooled in a subsequent clinker cooler (7), in which method the waste is incinerated in a separate compartment (9) subject to simultaneous supply of hot air, the exhaust gases produced during the waste incineration process being vented to the preheater for heating the cement raw meal, and the slag generated during the waste incineration process being extracted from the compartment, the waste is introduced via a waste inlet (11) onto a supporting surface (21) incorporated in the compartment (9) and in that, during incineration, the waste is transported through the compartment to the outlet (23) of the compartment along a circular path, characterized in that the compartment (9) is arranged at a distance from said calciner (3) or a preheater tower by means of a material chute (40), said material chute (40) enters a downward sloping duct, said duct carries exit gas from said compartment (9) and non-combustible material from waste fuel firing in said compartment (9) down into the calciner or preheater tower.

Provided is a monitoring method of a supply state of a treatment object, the monitoring method being capable of accurately evaluating the supply state of the treatment object in a surface melting furnace. The monitoring method is a monitoring method for monitoring a supply state of a treatment object in a surface melting furnace including a melting chamber and configured to melt, from a top surface side, a treatment object bed resulting from the treatment object supplied into the melting chamber from a lateral side of the melting chamber. The monitoring method includes: capturing an image of an evaluation target area on a melt surface resulting from the treatment object bed being melted, and generating thermal image data indicating a temperature distribution in the evaluation target area; and evaluating a supply state of a treatment object based on the thermal image data.
