Abstract :
The 300 MW CFB boiler has became the main type of electric power station boiler in china, which desulfate with the Limestone. Heat loss due to exhaust gas is the largest heat loss of boiler. Influencing factors of limestone desulfurization in CFB boiler on boiler thermal efficiency is described in the paper. New computation module for heat loss due to exhaust gas of CFB boiler is established. Heat loss due to exhaust gas of the 300 MW CFB boiler in china is calculated under BECR. Influencing extent of factors are analyzed quantificationally. The corresponding technical measures are presented.
