蒸汽发生器降低飞灰可燃物有效方法
The steam generator reduces the effective method of fly ash fuel
1、适当降低一次风压尽可能提高一次风温。
1. Make the wind pressure as high as possible.
2、蒸汽发生器保证足够的二次风量。在保持燃烧稳定的情况下适当开大中间二次风挡板开度使风粉充分混合。
2. Ensure sufficient secondary air volume. In the case of maintaining the combustion stability, the air powder should be fully mixed with the opening of the secondary air baffle.
3、在保证汽温、汽压及负荷的情况下适当降低上层给粉机转速,加大下层给粉机转速。
3. To ensure the steam temperature, vapor pressure and load, reduce the speed of the upper layer and increase the speed of the powder machine.
4、适当提高粉仓煤粉温度。
4、the upper layer and increase the speed of the powder machine.
5、尽可能避免制粉系统堵煤及断煤情况发生,保证制粉系统运行的稳定,维持合理的通风量,减少三次风量。
5. Avoid the occurrence of coal and coal breaking, ensure the stable operation of the powder system, maintain reasonable ventilation volume and reduce the air volume of three times.
6. It is not possible to pursue hot air temperature and keep the fire mouth too high, and the center of the flame is removed, causing the coal powder to stay in the furnace for less time, which can not be burnt out.
7、合理控制炉膛氧量在4~ 6℃,使燃烧在炉膛充分燃烧;
7、reasonable control the oxygen content in 4 ~ 6 ℃, the burning in the hearth burning fully;
8、降低煤粉细度,最好控制在煤粉经济细度,一般控制煤粉细度<10%
