Analysis on thermal economic indexes of
ca ptive stea m and po wer plant
GEN G Ho ng mei , ZHAN G Zo ng jun
Abstract : Co mbined wit h t he analysis o n examples of t her mal eco no my indexes f ro m a cap tive steam
and power plant , t hro ugh analysis and estimatio n fo r different perfo r mances of heat supply f ro m steam
and power plant , co nclusio ns are o btained fo r t he increase of t her malized power generating ratio and
fo r t he decrease of rated coal co nsump tio n fo r heat supply and power supply. U nder t he co nditio n of
meeting demands f ro m client s , heat supply parameters are reduced as lower as po ssible so t hat coal
co nsump tio n ratio will be decreased by applying lower p ressure no n adjustable at t racted steam to heat
t he feedwater .
Key words : t her mal eco no my ; rated coal co nsump tio n ; integrated t her mal power p ro ductio n ; energy saving
