Abstract
A burner installation includes a stack, a burner, a fuel valve, an air valve and a control device including a store storing burner pairs of values of air and fuel valve settings at firing rates and for controlling air and fuel valve settings. A stack flow regulator adjusts flow of combustion products through the stack and a pressure sensing arrangement monitors pressure of combustion products downstream of the burner. Respective pairs of stack flow regulator setting values and a measured value from the pressure sensing arrangement are stored for pairs of air and fuel valve settings values. The control device receives a feedback signal from the pressure sensing arrangement for comparing an actual pressure value with a stored pressure value and to trim the stack flow regulator setting to cause the actual pressure value from the pressure sensing arrangement to move closer to the stored pressure value.
