An online monitoring device for fouling and slagging based on capacitance principle differential measurement includes multiple measuring devices arranged at the same height of the boiler heating surface. Each measuring device includes a fixed sleeve and a sensor, one end of the fixed sleeve is fixed on the boiler heating surface, the sensor is connected with the fixed sleeve through screw threads, the end of the sensor near the boiler is equipped with a measuring probe. When measuring the thickness of ash residue on the monitoring surface, three sets of the measuring devices are at the same height of the monitoring surface. Each sensor is adjusted at a different position in the corresponding fixed sleeve to realize the differential measuring on ash residue thickness. Thus, the thickness of ash residue on the monitoring surface can be calculated based on the measured capacitance by applying the capacitance formula of planar capacitor.

A gasifier system for reducing the particle size of non-gas byproducts of the gasification process. The gasifier system generally includes a grinder that permits uninterrupted syngas flow during gasification of biomass that contains high amounts of silica and/or salts. The described system and method incorporates a grinder that breaks apart the resultant non-gas byproducts into finer particles that may be flushed out of a gasifier using the syngas stream. The particles may then be easily separated from the gas stream in a separator and collected in a char or waste bin for removal/disposal.

The present invention relates to burners and boiler structures of heating systems which work with solid fuel or which work especially with wood pellets, olive stones and other similar propellants. The burner has a C-shaped grate structure comprising a grate mount (4.2) for opening and closing an ash discharging mouth, and the top grate made up by the following components: Grate arms (4.1.2) that can move at a horizontal angle over connecting grate shafts (4.1.3) independent from each other; grate shims (4.1.4) located on the grate shafts (4.1.3) and between the grate arms (4.1.2); a shank (4.1.5) connecting the grate arms (4.1.2) to a grate frame (4.1.1), and the top grate to the grate mount (4.2), thus enabling the top grate to move in an upwards or downwards motion limited by supports (4.1.7, 4.1.8). Furthermore, the burner comprises uneven rails on which the top grate moves guided by guide pins (4.1.6).

A rotary bottom ash regenerating (RBAR) system [100] comprises a cylindrical body [110] that receives ash [17] containing reactant particles [10] that are partially reacted limestone compounds having unreacted cores [13] from a furnace. Sensors [140] sense physical parameters within the cylindrical body [110]. A controller [170] receives the output of the sensors [140] and information indicating the amount of unreacted core [13] and causes a fluid actuator [135] to spray a proper amount of regeneration fluid regulator [135] from a plurality of spray nozzles [131] to different locations within the cylindrical body [110] to regulate the temperature and to cause the reactant particles [10] to have a require content of regeneration fluid. This causes the reactant particles [10] to be regenerated and reused. This results in a lower limestone costs and less overheating of ash handling systems.

Methods treat ash from waste incineration, wherein the methods at least comprise: a) the digestion of the ash by a leaching liquor containing phosphate ions in solution such as to form a first solid phase comprising impurities and a first liquid phase comprising phosphate ions; and b) the separation of said first liquid phase comprising phosphate ions from said first solid phase. Step a) is carried out for a duration of less than one hour or at a temperature of more than 40 C.
