介绍蒸汽锅炉升火前与升压步骤有那些?
Introduces the steam boiler and booster step before the fire have those?
1.升火前
1. Before the fire
1.1 check hand-over records and register boiler technology.
1.2 check each part of the equipment and safety accessories (safety valve, water level gauge, pressure gauge, drain valve and leak dust removal equipment), confirmed rear can normal control.
1.3 for new clothes or overhaul of the boiler, check control response to the following aspects:
1.3.1 check boiler body, feed water system, smoke, wind system, the testing instrument, etc. Shall be in good condition.
1.3.2 check the drum or pot shell, the collection should be without your legacy tools and debris in the oven, pipeline without blocking.
1.3.3 dismantle the pipe set for inspection of blind flange on the road, the place such as manholes, hand hole and the connecting flange bolts should be tightened, pipe valves are adjusted to the ignition position.
1.3.4 driving feed water pump, the economizer water to the boiler. Water temperature of 40-50 degrees Celsius.
The lowest water level 1.3.5 water to the boiler water level indicator, to stop water, open water level gauge, the water level gauge water and low water level alarm.
1.3.6 open all equipment cooling system.
1.1查验“交接班记录”及蒸汽锅炉技术登记簿。

  1.2检查设备各部位和安全附件(安全阀、水位表、压力表、排污阀及透风除尘设备),确认正常后方可操纵。

  1.3对于新装或大修以后的锅炉,应对以下几方面进行检查操纵:

  1.3.1检查锅炉本体、给水系统、烟风系统、各检测仪表等均应完好。

  1.3.2检查锅筒或锅壳,集箱内应无杂物及贵遗留工具,管路无阻塞。

  1.3.3拆除各管路上因检验而设置的盲板,人孔、手孔及连接法兰等处的螺栓应拧紧,各管路阀门均调整至点火要求位置。

  1.3.4开给水泵、经省煤器向蒸汽锅炉上水。上水温度为40-50摄氏度。

  1.3.5上水至锅炉水位表的最低水位线时,停止上水,开启低位水位计、远传水位计及水位报警器。

  1.3.6开启设备所有的冷却系统。
2. The fire and booster
 2.升火与升压
2.1对锅炉机组烟道进行彻底透风。风机透风的时间约为5分钟,自然透风应不少于15分钟。

  2.2锅炉升水应按不同的燃烧设备所规定的操纵方法进行。对于链条炉排可按下述步骤操纵:

  2.2.1在炉排的前部展上一簿煤层,并在其上展好木材及引燃物。

  2.2.2启动风机,点燃引燃物并调节风门。待木材燃烧稳定后,缓慢转动炉排。

  2.2.3待煤燃烧稳定后,逐渐增加给煤量,调节送风量,使之燃烧正常。

  2.2.4按设备使用说明书规定,把握锅炉升火到供气的时间性。当蒸汽从空气阀中冒出时,即可封闭空气阀,并密切留意锅炉压力表,适当开大烟道挡板,加强透风,预备升压。

  2.2.5升火期间应控制省煤器内水温,在工作压力下应低于饱和温度400C。

  2.2.6当汽压上升到0.05-0.10兆帕时,应冲洗水位表。

  2.2.7当汽压上升到0.10-0.15兆帕时,应冲洗压力表的存水弯管。

  2.2.8当汽压上升到0.20-0.29兆帕时,应检查各联接处有无渗漏现象。

  2.2.9当汽压上升到0.29-0.39兆帕时,应试用给水设备和蒸汽锅炉排污装置
2.1 to thoroughly drafty boiler flue. Fan drafty time is about 5 minutes, natural wind should be not less than 15 minutes.
2.2 litres of water should be according to the different combustion boiler equipment manipulation methods by the rules. For the chain grate under the following steps:
2.2.1 coal seam in the front of the fire grate show in a book, and show good wood and ignition on its content.
2.2.2 start fan, ignition and lighting of the damper. After being wood combustion stability, slowly turn the fire grate.
Then after being coal combustion stability, increase gradually to coal, adjust air output, normal burning.
2.2.4 as stipulated in the equipment operation instruction, grasp the boiler fire off to the gas supply timeliness. When steam, from the air valve can be closed air valve, and closely monitor the boiler pressure gauge, appropriate to open big flue damper, strengthen the drafty, prepare booster.
2.2.5 during the fire should be controlled within the economizer, water temperature under the working pressure saturated temperature should be lower than 400 c.
2.2.6 when steam pressure rises to 0.05-0.05 mpa, flush water gauge.
2.2.7 when steam pressure rises to 0.10-0.10 mpa, trap tube should be flush pressure www.hnzbrn.com   gauge.
2.2.8 when steam pressure rises to 0.20-0.20 mpa, should check whether there is any leakage on the connection place phenomenon.

2.2.9 when steam pressure rises to 0.29-0.29 mpa, the available water supply equipment and drainage device
