Drying energy

The selection and operation of waste heat boilers for industrial furnaces is discussed in the Efficient Use of Energy, Dry den (1975). 

Adapted from Graham and Huffman (1981). The gasifier was rated at 0.84 GJ/h. The thermal efficiency is (cool gas energy)/(dry wood energy). 

Within the oxygen concentration range of 28 to 36% used in the experiments, 800 to 1,100 Nm3 of gas (dry) were generated per ton of refuse. This yields 1,100 to 1,400 kcal/Nm3 of energy (dry). The heating value of the gas increases with increasing oxygen concentration in the hot blast. 

Payback calculations refer to the whole solar energy drying system [31,32]. With appropriate division of the costs, there is of course nothing in the way of making the calculation only for the collector system [33,34]. Construction of the collectors can be planned on the basis of the economic optimum [35,36]. 

Most textile adhesive formulations are available in a waterborne liquid or solid (film or powder) form. When supplied as a film, the adhesive is unsupported, reinforced with fabric or nonwoven, or coated on both sides of a carrier material. These film adhesives are made flowable by heating to a melt and then gain strength on cooling back to a sohd form. Film adhesives offer convenience, since no coating operation is required by the user, energy (drying costs) is minimized, and waste is eliminated ... 

In general, in situ impregnation during sol-gel preparation enables well-controlled production of porous materials. As two process steps that consume considerable amounts of energy (drying and calcination of unimpregnated gel particles) are eliminated from the production process, this well-controlled product is expected to be economically attractive. 

Reports of quantitative data of the electric conductivity of NASICONs are few in number, and appear to differ considerably depending on the chemical composition and preparation conditions. SUva et al (2006) measured the d.c. conductivity of CaTi4(P04)6 produced by high-energy dry ball-milling for 15 h of a mixture of...

Wood, a renewable source, is not an important industrial fuel today. However, its use continues in some mral areas where it is often supplemented with liquid propane. In some underdeveloped countries, wood is still the principal source of energy. Dry wood contains from 1% to 12% moisture whereas green wood contains from 26% to 50% water. The resinous woods, like pine or cedar, yield about 18.5 MJ/kg of air-dried wood or, allowing for the moisture content, about 21 MJ/kg on a dry weight basis. Hardwoods have a heating value of about 19.4 MJ/kg. The energy available in present forest stocks is estimated to be equivalent to about 270 x 10 t of coal or about 2/3 of the equivalent oil reserves.
