Fuel rates

These characteristic conditions and values depend on reactor designs and fuel rates. 

Gas turbine fuel rates (heat rates) vary considerably, however Evans provides the following fuel rate graph for initial estimating. It is based on gaseous fuels. 

In an operating plant, the air rate can be adjusted at fixed heat output (constant steam rate for a boiler) until minimum fuel rate is achieved. This is the optimum so long as the warnings below ai e heeded. 

Turbine drives have higher fuel rate than reciprocating units. 

At the port position, the velocities of the air and fuel are considered constant, equal, and uniform across their respective tubes. Experimentally, this condition can be obtained by varying the radii of the tubes (see Fig. 6.2). The molar fuel rate is then given by the radii ratio...

Cost estimate for the Carlo Environmental Technologies, Inc., MTTD technology range from 30 to 69 per ton of soil or other material treated. Factors that influence costs are characteristics of the soil (most important) utility and fuel rates, and moisture content of the soil. The initial and target contaminant concentrations also affect costs (D101871, p. 28). 

In 1996, Delphi estimated the cost of processing wastes at 2.50 to 10.00/kg. Among the factors listed as affecting cost were quantity of waste, labor rates, initial contaminant concentration, characteristics of residual waste, waste handling and pretreatment, amount of debris, utility/fuel rates, and target contaminant concentration (D13821G, p. 24).
