The safety responsibility of Qingdao Shengli boiler is heavier than Mount Tai.

At about 1:30 in the morning of May 14, 2018, a boiler explosion accident occurred in an enterprise in Feixiang District of Handan, Hebei, resulting in 2 deaths and 2 injuries.

In the past less than two months, many domestic boiler explosions and tragic casualties and losses have made many people feel shudder. The boiler is safe to use, and the responsibility is more than Mount Tai! Then, how should the boiler pay attention to work safety during its use? How to avoid the tragic accident caused by improper operation? Below, Qingdao Shengli boiler, a state a class a boiler manufacturing qualification, special pressure vessel design qualification and the 2017 China boiler industry 20 enterprises, to discuss the correct use and operation of the boiler.


First of all, operators of industrial boilers must be professionals who hold the national special equipment operation permit (boiler certificate). The boiler room and other heavy ordinary people are strictly entered. The boiler work certificate is divided into three grades, I grade (primary) boiler work proof - steam boiler rated less than or equal to or equal to 0.4MPa with rated working pressure less than or equal to or equal to 0.5t/h, as well as hot water boiler and organic heat carrier boiler with rated power less than or equal to 0.7MW; II grade (intermediate) boiler work proof refers to the rated working pressure The steam boiler less than 3.8MPa, the stoker certificate of the hot water boiler and the organic heat carrier boiler, and the III grade (Advanced) boiler work certificate are the stoker certificate of the steam boiler that can be operated and the rated working pressure is greater than or equal to the 3.8MPa. Here, it is necessary to emphasize that a boiler with a higher level can be operated on a low level boiler. However, a low level stoker certificate can not operate a high-level boiler.


After the enterprise is equipped with a professional stoker, it is also necessary to arrange the normal work and work and rest time according to the specific production cycle plan, and strictly prohibit the fatigue of special types of work such as the stoker. In the operation and operation of the boiler, the stoker should first understand and record the structure characteristics of each type of boiler, the alarm system, the accident investigation and the response plan. Ensure that the stoker is able to see and understand the specific conditions of the boiler in every post and every class. In addition, the enterprise decision-making layer should also strengthen the awareness of the safe operation of pressure vessels such as boiler and other pressure vessels.


The boiler room of an enterprise should keep its neatness and regularity. Strict control and easy access to inflammable, explosive, dangerous chemicals, and idle people are not allowed. The boiler shall be used in accordance with the accessories supplied by the manufacturer, and the fittings shall be strictly and privately replaced. And in accordance with boiler production enterprises or relevant national standards, regular inspection and repair of boiler safety. All alarm and special abnormal conditions in boiler operation should be recorded and discharged in a timely manner.


In addition to the daily regular maintenance and maintenance of the enterprise, the enterprise should select the boiler and other pressure vessels while selecting the products and services of the qualified and powerful boiler supply enterprises. The products provided by Qingdao Shengli boiler are equipped with PLC automatic electric control, abnormal alarm and abnormal shutdown. When the boiler has abnormal pressure, abnormal replenishment and abnormal circulation, the electronic control system can alarm in time and control it automatically to avoid the bad and dangerous situation. The boiler enterprise should also respond in time to the after-sales service of the boiler. The victory boiler is 7 x 24 hours online, and the domestic commitment to respond within 24 hours or arrive at the scene. High quality products and excellent service can create safe industrial production.
