Abstract:
This paper presents the mathematical modeling of low pressure small boiler for SMEs. The model
use to predict the performance of the boiler. The boiler has of 40 cm diameter 180 em length
insulation that is 30 mm insulation of the head portion and the end of steam pot. and components
to reduce heat losses by heat transfer. water temperature feeds 32 the degree Celsius and at 0.5,
0.75,1.0, 1.25, 1.5, 1.75 and 2.0 barg steam pressures. the analysis result boiler steam efficiency
and using energy of boiler steam system. by use fuel, NG , LPG and Diesel Fuel at 0.5 barg steam
pressures, get the efficiency equals to 96.420% at 0.75 barg steam pressures, get the efficiency
equals to 91.237% at 1.0 barg steam pressures, get the efficiency equals to 89.542% at 1.25
barg steam pressures, get the efficiency equals to 89.067% at 1.5 barg steam pressures, get
the efficiency equals to 88.326% at 1.75 barg steam pressures, get the efficiency equals to
88.469% at 2 barg steam pressures, get the efficiency equals to 88.184% respectively efficiency of
steam pot shares to equal to 95.39% and way mathematics effective model of steam pot shares to
equal to 96.42% and valuable the deviation shares to equal to 1.07%
