    • 专利摘要:
    Three burners are supplied with pulverised fuel entrained in air from a splitter (1) and are brought to combustion under optimum conditions by adjustment of the secondary air flow (11) to each. Means, (6 and 11), are included by which the rates of flow of primary and secondary air can be determined and signals from these, and a representation of the total fuel supply are supplied to a computer (30) by which the amount of fuel flowing to each burner is deduced from the ratio of the air supplied to the burners.

    Claims (6)
    [1]
    Claim
    1 ”A method for determining the fuel consumption for each burner connected to a divider, to which atomized fuel is supplied in the primary air stream, by measuring and individually regulating the supply of secondary air to each burner and determining the total fuel consumption for all burners, that, in order to improve the accuracy of determining the fuel consumption in each of the burners, additionally measure the flow rate of the primary air supplied to the divider, the flow rate of the secondary air is adjusted until the dose reaches the total of air corresponding to the optimal combustion conditions of this dose the total amount of fuel supplied to the distributors, and the ratio of air flow fed to each burner, determine the amount of fuel supplied to each burner "
    [2]
    2 "The method according to p" 1, characterized in that intermittent short-term disturbances are introduced to each burner by changing the fuel consumption and the flame temperature is measured, and the achievement of optimal fuel combustion conditions is judged by the amount of time between the moment the disturbance is introduced by the change in fuel consumption and the moment the temperature reaches flame maximum value.
    [3]
    3 "A system for determining the fuel consumption for each burner, containing devices for measuring and regulating the supply of secondary air to each burner, a device for determining the total fuel consumption, characterized in that, in order to improve the accuracy of determining the fuel consumption for each burner when feeding fuel to all burners in the primary air flow through pipelines from one divider, it further comprises a device for measuring the flow of primary air supplied to the divider, devices for determining Making optimal conditions for the combustion of fuel in each burner, connected to devices for regulating the supply of secondary air to each burner, and a device for calculating fuel consumption for each burner, is connected. "with devices for measuring the flow rates of primary and secondary air and with a device for determining the total fuel consumption"
    [4]
    4. The system according to n »3, with the fact that the device for determining its optimal conditions is I η
    Fig.Z
    10 .
    wound of fuel in each burner Contains means for intermittent and short-term changes in fuel consumption after the divider and means for measuring changes in the temperature of the flame of the burner after intermittent short-term changes in fuel consumption
    [5]
    5 "The system according to claim 3, characterized in that the device for measuring the secondary air flow contains a Venturi pipe installed on the secondary air supply line in front of each burner"
    [6]
    6 "System according to claim 3, characterized in that the device for measuring the flow rate of primary air contains an insert with a wing profile installed in the primary air supply pipe"
