Abstract (en)

[origin: EP0342347A2] In order considerably to improve the combustion during the operating time of smaller ventilator burners also, in particular one or two-stage ventilator burners, with reasonable outlay, as the main deregulating factors the pressure (pL) and temperature ( theta L) of the combustion air are measured and from these, on a compensator (25), a simple compensation function is determined, with which, on a superposition unit (27), action is taken on the combustion air flow (L<*>) and/or on the fuel flow (B<*>). Precisely in said burners, the greater part by far of the influence of deregulating factors stems from said main deregulating factors. <IMAGE>
