Provided herein is a process for improving the heating value of a cellulosic waste material. The process includes the steps of treating the cellulosic waste material with an acid solution, recovering heat produced by treating the cellulosic waste material, and filtering the treated cellulosic waste material to produce a filter cake. The disclosure also relates to a system for implementing the process.

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.

A method for reducing the emission of contaminants by a furnace is provided. The method includes forming a bed from a stream of fuel within the furnace; fluidizing the bed with flue gas from the furnace; and heating the fuel within the bed so as to generate char, ash and contaminants. The method further includes capturing the contaminants via the ash.

A process of making a fuel product from a non-combustible high protein organic material such as a waste material. The high protein organic material is pulverized to a particle size whose particle size less than 2 mm. The moisture content of the high protein organic material is mechanically reduced and dried to reduce the moisture content to less than ten percent (10%). The high protein organic waste material is fed into a combustion chamber and separated during combustion such as by spraying of the high protein organic waste material within the combustion chamber. Temperature and combustion reactions within the combustion chamber may be controlled by injection of steam within the combustion chamber.

A method and device for drying wood chips to be used as raw material for a gas-generating reactor, the device being disposed between the storage for wood chips and the reactor. Product gas of the reactor is at least partially used in a block-type thermal power station (BHKW), and hot air from the housing of the block-type thermal power station is used to heat and dry wood chips in a drying hopper which has at least one outlet for the cooled humidified air. The wood chips enter the drying hopper through a first air-tight lock and exit the drying hopper through a second air-tight lock.
