3.3 锅炉首次点火Boiler initial firing

3.3.1锅炉在升火前应进行全面检查（包括有关附件、管道）而后进行给水工作，未进水前必须关闭排污阀，开启排空气阀，让锅炉内空气可以排出。

The boiler shall be throughly inspected ( including accessaries, piping)before firing, then start water filling. The drain valve must be shut oof before water filling, open the air valve , exhuast the air within the drum.

3.3.2将已处理的水通过省煤器缓慢注入锅炉内，进水温度一般不高于90℃，当锅内水位升至水位表最低水位时，即关闭给水阀门，待锅内水位稳定后，观察水位有否降低。

Slowly fill the treated water into the boiler , filling water temperature shall not excess 90℃.When water level in drum reaches the bottom level of level gauge , shut off the feed water pump . After the water level is steady , check for water level fall. 3.3.3锅炉升火时，应将过热器生火排汽阀、疏水阀打开以冷却过热器。疏水阀在汽压升高到0.2Mpa时关闭。 When the boiler is ignited , the fire exhaust valve, drainage valve of superheater shall be open to cool the superheater . The drainage valve shall be shut off when steam pressure rise to 0.2M.

3.3.4升火时，开启点火门，在炉排前端放臵木柴等引燃物，（严禁铁钉带入）引燃，开大引风机烟气调节门，增加自然通风，引燃物燃烧后，调小烟气调节门，间断地开启引风机，当煤层燃烧旺后，可关闭点火门，向煤斗内加煤。间断开启炉排，并在左侧拨火孔处加强观察着火情况，适当进行拨火，待前拱烧热煤能连续着火后调节鼓引风量，炉膛负压维持在20~30Pa，使燃烧渐趋正常。

When furnace is ignited ,switch on ignition door , ignite the fuel, open the ID fan flue adjust door to increase natural ventilation, narrow the flue gas adjust door after ignition. Keep the ID fan on and off, start manually fueling after strong combustion . The FD fan may be started and ignition door may be closed when combustion is strong. Observe the fire through poking hole and poking with proper manner. After furnace is heated and coal is continuously burned, the induced draught volume may be adjusted, keep the negative pressure of furnace at 20-30Pa,let combustion at normal stage.

3.3.5升火时温度增加不宜太快，避免各部分因受热不同而产生过大的热应力，影响锅炉寿命，初次升火从冷炉到气压升至工作压力的时间以6~8小时为宜，以后升火时除有特殊情况需要用蒸汽外，冷炉不少于2小时，热炉不少于1小时。

When ignited, the temperature rise shall not be too quick to avoid excessive heat stress due to different heating parts and affect life span of the boiler. For initial firing, from cold furnace gauge pressure to its work pressure prefers 6-8 hours , in case steam is needed in emergency during firing, the cold furnace shall take more than 2 hours, and hot furnace shall take less than 1 hour. 3.3.6从点火起到额定压力过程中应由前后集箱和左右（前后）防焦箱，各放水三次（放水时应特别注意保持正常水位）。 Water shall be drained three times ( it shall be noted that normal water level shall be remained) from front and rear header and left and right ( front and rear)clinkering box when boiler is ignited and steam reaches its rated pressure
