This paper introduces the principle, configuration, function of combustion diagnosis and operation instruction system of utilityboilerbased upon the flame image processing as well as its application in the 300 MW utility boiler.
The results were rather satisfactory. The results showed that the transfer factors for power boiler industrial boiler and hom-stowe were 0.948 0.925, and 0.595 respectively, the 1986's data were 21.31kg/t, 17.85kg/t and 11.54kg/t respectively.
The paper gives a common introduction of expert systems adopting the artificial intelligence systems and describes it by taking examples of the automation diagnoses of power boiler and steam turbine failures.
The combustion models taking into account the pyrolysis of the particle and the heterogeneous combustion of char have been validated using intensive measurements performed on the 600 MW utility boiler.
A metallurgical evaluation of clad alloy 800H tubing after 17 years of service in a coal fired utility boiler
Corrosion of TP347H FG stainless steel in a biomass fired PF utility boiler
Modelling of a Utility Boiler Using Parallel Computing
Combustion characteristics of vacuum residue in a test furnace and its utilization for utility boiler
Moreover, a formula to calculate the setting parameters is presented, together with a practical example of its engineering application in superheated steam temperature control with single-stage attemperation in a power plant boiler.
Observations of Power Plant Boiler Tube Failures and Related Microstructures
Low-cycle fatigue and cracking resistance of power plant boiler pipes and steam lines of 12Kh1MF steel
David Smith, a student in my Spring 2002 Mineralogy class, selected a sample of vesicular slag believed to have formed in a coal power plant boiler.
In this case roll-race mills are widely used to prepare pulverized coal for firing power plant boiler furnaces.
Selection of stainless steel tubes to minimize hot corrosion in utility boilers
Austenitic stainless steel tubes of AlSI 304, 316, 321, and 347 types are sometimes exposed to severe hot corrosion environments in superheaters and reheaters of utility boilers.
In this paper, the experience gained in utility boilers, with temperatures in the range of 800 °C to 1400 °C, is reported.
Several issues for applying it to utility boilers have been investigated in line with the present results, and some suggestions have been made.
Considering baseline mercury removal efficiency of up to 50% in the utility boilers due to the acid gases containing in the flue gas, above results indicate that 90% or more of gaseous mercury could be removed.
