EFFECT OF POWER PLANT STEAM BOILERS' CONTROL SYSTEM ON THE STABILITY OF FUELLING

Abstract

Combustion processes in furnace installations are characterised by parameters varying with time, thus flucuating more or less around the required value. This concerns velocity distribution of the air flowing into the combustion chamber as well as the fuel, thus fuel- air concentration will change in space and time, resulting in pressure and temperature fluctuations. In furnace installations, howerer, flame is the best 'stability' indicator usually more intensively signalling disturbances occurring in any unit of the equipment.
