Problems solved by technology

Poor gas quality can cause fouling in such small holes
[0003] Currently, fouling in the burner nozzle is difficult to monitor directly without shutting down the gas turbine and opening the gas turbine casing and inspecting the burner
Obviously, in practical situations, the above method cannot be frequently applied for burner fouling monitoring, and the generated deposits (i.e. fouling) may lead to insufficient mass flow to the combustion chamber , which will lead to unstable combustion

Abstract

The invention provides a method and device used for monitoring and predicting scales in a combustor. The method comprises steps of by acquiring one kind of or various kinds of combustion signals of the combustor and / or a gas system corresponding to the combustor; determining combustor performance models corresponding to the combustion state signals according to the combustion signals; acquiring acombustor performance reference model corresponding to the combustor; and finally, according to the combustor performance model, by combining the combustor performance reference model, determining early warning information corresponding to the combustor. Thus, the generated combustor performance model is quite practical; by use of the method and the device, large quantity of research funds and usecost can be reduced; the scales and the development trend of the combustor can be monitored and predicted in a quite simple and convenient mode; and the method and the device can be used for strategyplanning of maintenance of economical combustors or gas turbines.

Description

technical field [0001] The invention relates to the field of gas turbine burners and gas systems, in particular to a method and device for monitoring and predicting fouling in the burner. Background technique [0002] Typically, in a gas turbine gas system, the gas flow path of the following two components contains holes with a small flow diameter: one is the control valve and the other is the burner. Poor gas quality can cause fouling in such small holes. [0003] Currently, fouling in combustor nozzles is difficult to monitor directly without shutting down the gas turbine and opening the gas turbine casing and inspecting the combustor. Obviously, in practical situations, the above method cannot be frequently applied for burner fouling monitoring, and the generated deposits (i.e. fouling) may lead to insufficient mass flow to the combustion chamber , which will lead to unstable combustion. Contents of the invention [0004] In view of this, one of the problems solved b...
