Abstract:
A municipal or like refuse is crushing, mixing with crushed limestone, dry up in two stages - by hot air and by part of solid products of pyrolysis which other part goes on washing out and filtration. Pyrolysis is carried out in. two stages - due to heat of the specified part of solid products of pyrolysis and simultaneous neutralization of allocated hydrogen chloride by limestone with reception of calcium chloride, and then due to heat of final chimney gases of the combustion chamber, where in three stages the washed solid products of pyrolysis preliminary drained by a part of combustion chamber slag are burnt together with liquid and gaseous products of pyrolysis. Gas allocated at pyrolysis condense and divide on organic, which are liquid fuel and water phases. Air after a dryer moves to blowing away of light organic substances from the specified water phase, is heated up due to heat of slag and moves in combustion chamber. Washing water goes on allocation of salts of heavy metals and calcium chloride, and slag after molding of a concrete mixture goes to the chamber of thermohumid processing of the slag concrete by a part of damp chimney gases after drying calcium chloride, other part of gases moves to manufacture of liquid carbon dioxide.

Abstract:
Coal ash, which also consists of fly ash, is a very fine granular solid residue obtained as a by-product of coal combustion. The invention relates to the surprising result that a fuel can be obtained from coal ash. The process involves a pneumatic separation of the coal ash at relatively low temperatures. The coal ash is separated into at least two size fractions. The size fractions obtained by the process of this invention include at least one with lower carbon and another containing increased levels of carbon in the range of 50% by weight and a heating value in the range of 4000 to 6000 Btu/lb.

Abstract:
Preparation and burning of biomas-derived fuels such as wood waste or peat. Wood waste or "hog fuel" from the forest industries is of particular interest. Normally the entire stream of this material must be finely ground if it is to be successfully burned in an air suspension burner without any fossil fuel support. It has now been discovered that a bimodally sized fuel can be used. Only about 10-20% of the total heat energy is provided from a portion ground to a size less than about 100 mu m. This serves as an ignition component for a principal fuel which may be of much larger size. The usual hog fuel pile contains both bark and wood. Of these two materials, bark is much more friable and easily ground to fine particles size than wood. A major reduction in grinding energy is achieved by selecting the more friable material to be ground to fine size as the ignition fuel. The more resistant material is used as the principal fuel. When using a bimodal system, best results are obtained when the amount of ingition fuel sent to the burner is maintained constant. Load swings are accommodated by varying only the principal fuel component.

[Problem] To provide a rotating classifier which can keep classification performance high and which can prevent blockages caused by biomass and the like. [Means for Resolution] The rotating classifier is characterized in that: comb teeth-like protrusion portions protruding toward a fixed member side are provided on top of rotary classification fins at intervals along the circumferential direction of the rotating classifier fins; a first gap is provided between an upper end portion of each of the comb teeth-like protrusion portions and a lower surface of the fixed member; a second gap formed between a protrusion portion and a protrusion portion adjacent to the protrusion portion is connected to the first gap; and an air stream flowing from the radial outside to the radial inside of the comb teeth-like protrusion portions through the first gap and the second gap is formed due to the rotation of the rotary classification fins.
