A fuel material processing system includes a hopper assembly configured to receive a fuel material. A drying system is configured to remove moisture from the fuel material to generate a dried fuel material. A material delivery system is configured to provide the dried fuel material to a combustion system.

In a method for physical and thermochemical treatment of biomass, the biomass moisture content is reduced in a dryer and ammonia (NH.sub.3) is also released from the biomass during drying. The dried biomass is then either pyrolyzed in a pyrolysis reactor and the pyrolysis gas is forwarded to and combusted in a combustion device to form flue gas, or is combusted in a combustion facility unit to form flue gas. In either case the flue gas is fed to a mixer. Oxygen (O.sub.2) is metered to the flue gas in the mixer and is fed directly to the dryer as drying gas. As the drying gas passes through the dryer, the sulfur dioxide (SO.sub.2) contained in the drying gas and/or the sulfur trioxide (SO.sub.3) chemically reacts with the ammonia (NH.sub.3) to form ammonium sulfite ((NH.sub.4).sub.2SO.sub.3) and/or ammonium sulfate ((NH.sub.4).sub.2SO.sub.4). Also a treatment facility physically and thermochemically treats the biomass.

The present invention relates to system and method for reducing the volume of sewage sludge, the system comprises a dryer adapted to receive the sewage sludge and a drying gas and produce a mixture comprising a dried sludge component and a gaseous component therefrom. The system further comprises a solid-gas separator for separating the dried sludge component from the gaseous component. The system further comprises a hot air generator connected to said solid-gas separator and the dryer, and adapted to receive a feed gas and at least a portion of said dried sludge component from the solid-gas separator to combust the dried sludge component to produce a heat of combustion and convert, using the heat of combustion, the feed gas to drying gas for supply to the dryer.

Methods and apparatuses can be configured to facilitate sorting of paper from garbage and/or single stream recycling and subsequently process that separated paper to remove the contaminants from the paper so that the paper is in an acceptable condition for recycling. In some embodiments, the apparatus and method may utilize at least one dryer device that is configured to heat the paper without combusting the paper to remove water from the paper. The dryer device can also be configured to mix the paper as it is dried while also removing particulate contaminants off of the paper to clean the thrown away paper sufficiently so that the paper is in a condition that is acceptable for recycling into a paper product (e.g. a cardboard box, paper plate, sheets of paper, etc.).

Disclosed is a combustion machine, including: a hopper, a drying mechanism and a combustion mechanism. The hopper is configured for storing materials and conveying the materials to the drying mechanism. The drying mechanism includes a conveying mechanism and a drying chamber, and the conveying mechanism is connected with the hopper and conveys the materials in the hopper to the drying chamber. The combustion mechanism includes a combustion chamber connected with the drying chamber via a material conveying pipeline, and a fire outlet pipe arranged in the combustion chamber and used for outputting flame. A hot air pipeline is connected between the combustion chamber and the drying chamber, and a first exhaust fan is arranged in the hot air pipeline.
