FIELD: steam boiler units.
SUBSTANCE: invention relates to the regulation of steam boiler units and can be applied in automation systems for regulating fuel consumption for a steam boiler. An automated system and method for regulating fuel consumption, according to which they provide constant measurement of flow parameters, pressure and temperature of steam from the boiler, pressure and temperature of feed water to the boiler and pressure Psc the point of connection of each of the boilers to the general station steam collector of the TPP. Such a regulating effect on the fuel supply feeders is developed with the help of a fuel consumption regulator in order to maintain the balance of the specified and consumed heat of fuel combustion for the production of steam heat at the outlet of the boiler in the basic mode, or the balance of the specified and expended heat of fuel combustion for the production of steam heat consumed at the point of connection of the boiler to the general station steam collector of the TPP, in the regulating mode. In the basic operating mode of the boiler, the consumed heat Qpb of fuel combustion of a steam boiler is determined by the formula Qbs = Fds*(is(Tds,Pds)-ifw(Tfw,Pfw)), the specified heat Qgs of fuel combustion: Qgs= Fgds*(ins(Tnds,Pnds)-infw(Tnfw,Pnfw)). In the regulating mode, the consumed heat Qrs = Fds*(irs1(Tds,Rsc)-ifw(Tfw,Pfw)), and the specified heat Qngs = Fds*(irs2(Tnds,Pgsc)-infw(Tnfw, Pnfw)).
EFFECT: higher precision of heat generation and less transport lag of the control action.
