FUELS FROM WASTE

Kirk-Othmer Encyclopedia of Chemical Technology (4th Edition) [Pg.52]

Physical Properties. Physical properties of waste as fuels are defined in accordance with the specific materials under consideration. The greatest degree of definition exists for wood and related biofuels. The least degree of definition exists for MSW, related RDF products, and the broad array of ha2ardous wastes. Table 3 compares the physical property data of some representative combustible wastes with the traditional fossil fuel bituminous coal. The soHd organic wastes typically have specific gravities or bulk densities much lower than those associated with coal and lignite. [Pg.53]

Fuel Specific gravity Bulk density, kg/m Moisture content, wt % [Pg.53]

Specific gravity is the most critical of the characteristics in Table 3. It is governed by ash content of the material, is the primary deterrninant of bulk density, along with particle size and shape, and is related to specific heat and other thermal properties. Specific gravity governs the porosity or fractional void volume of the waste material, ie. [Pg.53]

There has been increased interest in firing wood waste as a supplement to coal in either pulverized coal (PC) or cyclone boilers at 1—5% of heat input. This appHcation has been demonstrated by such electric utilities as Santee-Cooper, Tennessee Valley Authority, Georgia Power, Dehnarva, and Northern States Power. Cofiring wood waste with coal in higher percentages, eg, 10—15% of heat input, in PC and cyclone boilers is being carefully considered by the Electric Power Research Institute (EPRI) and Tennessee Valley Authority (TVA). This practice may have the potential to maximize the thermal efficiency of waste fuel combustion. If this practice becomes widespread, it will offer another avenue for use of fuels from waste. [Pg.59]

The fuel properties of wood can be summarized by ultimate and proximate analyses and deterrnination of heating value. The analytical procedures are the same as those for coal, but with some modifications. Analytical results generally vary about as much within a species as they do between species, except that softwood species generally have a higher carbon content and higher heating values than hardwood species because of the presence of more lignin and resinous materials in softwood species (see Fuels from waste). [Pg.332]

It is reported that Hitachi Zosen Corp. of Japan has begun trial operation of a commercial-scale device for the conversion of waste plastic to oil. Details of the device are provided. It is also reported that Mitsubishi Heavy Industries Ltd. (MHI) has installed a pilot plant for producing gas fuel from waste plastics. The MHI system is described. [Pg.96]

That is why, since 1969, the global C02 emissions from energy use grew at the fastest rate [1], Therefore, renewable fuels (including biofuels) have been grown fast which are expected to grow at 8.2% p.a. from 2010 to 2030 [2]. One of the new energy sources is fuel from waste. [Pg.442]
