LOW COST, PORTABLE BRIQUETTING MACHINE - RURAL USE

The paper presents the results of a project focused on the development of briquettes from the waste wood (sawdust) resulting from the main waste from timber companies. This waste wood currently lacks a useful purpose, and its indiscriminate burning generates CO and CO2 emissions. Sawmill waste is a big problem especially in urban cities.

1.6 Wood Waste Combustion In Boilers

Various boiler firing configurations are used for burning wood waste. One common type of boiler used in smaller operations is the Dutch oven. This unit is widely used because it can burn fuels with very high moisture content. Fuel is fed into the oven through an opening in the top of a refractory-lined furnace.

Calcium carbonate waste from an integrated pulp and paper

Jul 24, 2007 · Calcium carbonate is used in large amounts in the pulp and paper industry as a paper filler. When it is manufactured, the calcium carbonate waste is purged from the process. Here we demonstrate that, due to the elevated calcium concentration of 168.5 g kg−1 dry weight (dw), alkaline pH of 12.6 and neutralizing (liming) effect value of 42.4% expressed as Ca equivalents, this waste is a

Hog Fuel – What is it? & Why is moisture measurement

Apr 25, 2012 · Mills must dispose of wood waste from paper mills. Price of natural gas is very low due to hydro-fracking, but mills still needs to dispose of the hog fuel, so they use it as a boiler fuel. Hog fuel moisture varies widely. Accuracy of 1 to 2 % across the 30-65 % moisture range is acceptable as sample handling of grab samples can't provide any
