Title:
【発明の名称】微粉炭燃焼炉を運転する方法
Document Type and Number:
Japanese Patent JP2003506657
Kind Code:
A
Abstract:
A method of operating a pulverized coal-firing furnace is provided which includes injecting air from an upper compartment generally in opposition to a swirling fireball. The method also provides the step of sensing a temperature characteristic of one side of a convection pass of the furnace. The sensed value, in accordance with the method of the present invention, is then evaluated to determine if the sensed value of the temperature characteristic exceeds an allowable value. In response to a determination that the temperature characteristic exceeds the allowable value, the momentum of the air injected through the upper air compartment is changed. After the step of changing the momentum of the air injected through the upper air compartment, the temperature characteristic of the one convection pass location is sensed to obtain a post adjustment value of the temperature characteristic and compared to an allowable value.
