The slurry picking process which extracts the fuel slurry which includes the coal and the limestone and the water which are supplied

摘要

PROBLEM TO BE SOLVED: To provide a calorific value measuring method of fuel slurry which removes a factor of a measurement error by a change in limestone and water included in the fuel slurry, and highly accurately measures a calorific value of the fuel slurry, and also to provide a control method of combustion equipment properly constructing a control system of pressurized fluidized bed combustion equipment by using data on this calorific value.;SOLUTION: This method has a slurry gathering process for gathering the fuel slurry including coal, the limestone, and the water supplied to the combustion equipment, an acid treatment process for extracting an undissolved material by acidly treating the gathered fuel slurry, and a quantitatively determining process for determining the calorific value per unit mass by measuring a temperature difference before and after combustion by burning the undissolved material extracted by the acid treatment process.;COPYRIGHT: (C)2003,JPO
