TODOROVIĆ, D. ŢIVKOVIĆ, M. MANĈIĆ, D. MILĈIĆ 4. COEFFICIENT OF EXCESS AIR RATIO DURING THE BOILER'S START UP Coefficient of excess air during the boiler's start-up r is defined by the following assumptions [11]:  starting up the boiler is carried out at constant sub-pressure in the combustion chamber, which is equal to the vacuum, which is maintained in the stationary mode, and,  suction of the waste air from the atmosphere, which depends on non-hermetic boiler's properties, is considered as a constant value that is determined by the constructive scheme of the fuel supply and technical condition of the boiler. 2 Characteristics of excess air ratio depending on a wide range of boiler load [11] 5.	cache/fumecheng-114.pdf	txt/fumecheng-114.txt
