A vibrating screen feed conveying apparatus for conveying and separating sticky “moisture laden bulk solids” which are sticky and wet flowing onto a vibrating screening feeder and into a hopper. The apparatus includes a bed on which material is conveyed, a longitudinal counterbalance supported on a plurality of isolation springs, a plurality of inclined drive springs extending between the bed and the longitudinal counterbalance, and a plurality of stabilizers for controlling movement of the drive springs along their central axes. A plurality of vibratory motors, each having rotatable eccentric weights are attached to the rear end of the longitudinal counterbalance. The eccentric weights rotate in phase with one another to vibrate the bed at a vibration frequency.

Provided is a method for predicting and evaluating adhesion of combustion ash in a coal-mixed combustion boiler in which biomass is used as renewable energy, the method comprising: ashing a sample to prepare an ashed test sample, the sample being obtained by mixing the biomass with coal that is main fuel of the coal-mixed combustion boiler, at a predetermined additive ratio; sintering the ashed test sample under a combustion temperature condition of the coal-mixed combustion boiler to generate sintered ash; testing the sintered ash by a rattler tester to obtain a sticking degree from a ratio obtained by dividing a weight of the sintered ash after the test by a weight of the sintered ash before the test; and evaluating in advance an adhesion state of the combustion ash in the coal-mixed combustion boiler on a basis of the sticking degree.

The inventive technology includes methods and apparatus for the generation and application of segregated catalytic additives for the pre-combustion treatment of carbonaceous fuel and/or feedstocks. The application of such segregated additives results in the reduction of environmentally harmful emissions during combustion as well as gasification processes. Specifically, pre-combustion treatment of carbonaceous materials with the inventive additives results in the reduction of NOx and/or mercury emissions by least 20% and 40% respectively.
