This paper presents an overview & current sources and forms of raw .materials for wood energy use and the types of machines available to convert them to the desired form for boiler fuel. Both the fuel source or raw material, and the combustion furnace will dictate the requirements for the processing system. Because of the wide range of processing equipment available, systems can be designed to ...

Analyses were conducted on 10 grass species from permanent grasslands in the Note? Leniwa and Bystra valley. Their chemical composition was assayed, their heat of combustion heating value determined. The cellulose content ranged 33.38% to 38.68%, while lignin 15.42% 21.99%, that hemicellulose 30.27% 34.31%. grasses comparable wood 2- 3-year-old willows other fast-growing energy crops. However, ...

The use of renewable wood-based fuel has been increasing in the last few decades because it is said to be carbon neutral. However, wood-based fuel, and especially used wood (also known as recycled wood or waste wood), is more corrosive than virgin wood (forest fuel), because of higher amounts of chlorine and heavy metals. These elements increase the corrosion problems at the furnace walls where...

This paper presents a preliminary research result of spatially quantifying and allocating the potential activity of residential wood burning (RWB) by using demographic, hypsographic, climatic and topographic information as independent variables. We also introduce the method for calculating PM2.5 emission from residential wood combustion with the potential activity as primary variable. A linear ...

Torrefaction is an effective pretreatment method to improve the uniformity and quality of lignocellolosic biomass before further thermal processing (e.g., gasification, combustion). The objective of this study was to determine the impacts of torrefaction as a pretreatment before liquefaction. Wood chips were torrefied for 2 h at three different temperatures (230, 260, 290 °C) and then subjected...

During combustion of solid fuels in the material inlet end of cement rotary kilns, local reducing conditions can occur and cause decomposition of sulfates from cement raw materials. Decomposition of sulfates is problematic because it increases the gas-phase SO2 concentration, which may cause deposit formation in the kiln system. SO2 release from cement raw materials during combustion of solid f...

An inventory of volatile organic compound (VOC) and nitrogen oxides (NOx) emissions is an important tool for the management of ground-level ozone pollution. This paper has two broad aims: it illustrates the potential of a geographic information system (GIS) for enhancing an existing spatially-aggregated, anthropogenic emissions inventory (EI) for Tucson, AZ, and it discusses the ozone-specific ...

Through the millennia wood stoves for cooking have been notoriously inefficient and slow. Electricity, gas or liquid fuels are preferred for cooking when they can be obtained. In the last few decades a number of improvements have been made in woodstoves, but still the improved wood stoves are difficult to control and manufacture and are often not accepted by the cook. Gasification of wood (or o...
