INDUSTRIAL POWER BOILER, METHOD OF OPERATION AND CONTROL SYSTEM Russian patent published in 2013 - IPC F22B33/12 

FIELD: power engineering.

SUBSTANCE: fuel and air is supplied into a burner, burnt in a firing hood, to which the burner adjoins, to create combustion products, afterwards combustion products are removed from the firing hood into an afterburning chamber, in which air is supplied into the combustion products with subsequent separation of combustion products into two flows. The first flow of combustion products is supplied to a heating surface, with subsequent heat removal from combustion products, afterwards the first flow of combustion products is removed from the afterburning chamber into the nozzle of combustion products discharge. The discharge of the second flow of combustion products from the afterburning chamber is carried out into a bypass, with subsequent removal of combustion products from the bypass into the nozzle of combustion products discharge and additional air supply into the second flow. Also composition and temperature of combustion products that are inside the nozzle of combustion products discharge, are monitored.

EFFECT: reduced temperature load at a bypass, expanded range of load at an industrial power boiler, stabilisation of temperature and composition of combustion products.
