#CMT# #/CMT# The adjusting method involves controlling air ratio, when variation of the combustion air flow or fuel quantity is less than or equal to a variation, and speed variation of the combustion air flow or fuel quantity is less than or equal to a limit speed. An assignment function is carried out during a control phase in predetermined time intervals, and a function of operating conditions is generated. After an initial start-up or burner start-up after repair, the variation velocity of the combustion air flow and amount of fuel is temporarily limited to a value smaller or equal to the speed limit. #CMT#USE : #/CMT# Method for adjusting an air ratio of a combustion air-fuel mixture to a desired air speed in air-fuel mixture combustion in a heater with combustion air dispensers for varying a quantity of combustion air and fuel dispensers for varying an amount of fuel. #CMT#ADVANTAGE : #/CMT# The variation velocity of the combustion air flow and amount of fuel is temporarily limited to a value smaller or equal to the speed limit, after an initial start-up or a burner start-up after repair, and hence ensures improved mode of operation with a minimum cutoff form changing even faster performance with variations, easy to obtain the reproaching portion of the control signal, improved subsequent operation by fine updates, easy controlled of the low emissions by the regulation, and improved mode of operation in response to changing operating and boundary conditions by using the air ratio adjusting method. |
