燃煤炉加钙脱硫后热平衡的修正与分析

Thermal Balance Modification and Analysis of Desulphuration with Addition of Calcium-based Sorbent in Coal-fired Boiler

本文从石灰石脱硫化学反应方程导出加石灰石后烟气成分和炉内热平衡修正计算式，并示出了对中硫煤和高硫煤修正与不修正的区别，供热力计算和燃烧脱硫操作参考。

Modified calculation formulas for gas composition and thermal balance of coal-fired boiler are derived from chemical equations of desulphuration with limestone.The differences between high-sulphur-coal and medium-sulphur-coal in calculation with modified models and models without modification are discussed too. The modification can be used as reference in thermal calculation and operation of desulphuration during coal burning.
