Abstract:
A method for operating a boiler plant for heat generation, the boiler plant including a fed air plenum and a combustion space in connection with the air plenum, and a burner operable with a liquid and/or gaseous fuel arranged on a head side of the combustion space, said burner comprising means for, at least in association with an introduction of combustion air from the air plenum, bringing about flame stabilization in the combustion space, and means for flue gas recirculation, said plenum being in connection with at least one blowoff device, said method comprising:during a startup phase of the boiler plant, predeterminedly opening the blowoff device, thus temporarily lowering an admission pressure in the air plenum and the air mass flow through the burner, and thereby temporarily raising an equivalence ratio of the burner during the startup phase of the boiler plant.
