Title:
酸素燃焼ボイラ設備の脱塵装置入口温度制御方法及び装置
Document Type and Number:
Japanese Patent JP6471485
Kind Code:
B2
Abstract:
A combustion-support-gas bypass line is provided to cause combustion support gas to bypass a preheater. A combustion-support-gas flow control damper is provided in the combustion-support-gas bypass line. An inlet temperature of a deduster is measured by a temperature sensor and the inlet temperature measured by the temperature sensor is inputted to a controller and is compared with a set temperature more than an acid dew-point preliminarily set in the controller. On the basis of a comparison result, an opening-degree control signal is outputted from the controller to the combustion-support-gas flow control damper so as to make the inlet temperature to a set temperature more than an acid dew-point.
