elasticity point of boiler tubes
In the near future, at home and abroad more than hazardous chemicals, major accidents have occurred, causing casualties and property losses. Is a profound lesson, Henan Energy Regulatory Office will co-Provincial Development and Reform Commission issued the "Notice on alternative transformation of the province's coal-fired power business major hazard (liquid ammonia tank)" and actively promote the province's power industry ammonia tank alternative transformation.
"National Development and Reform Commission and the National Energy Board to implement the views on the promotion of electricity reform and development of the field of safety of" clearly "to strengthen the major hazards source control, there are significant hazards during the production of coal-fired power generation enterprises should study the implementation of major hazards alternative rehabilitation programs. " Henan Province TV as fire, liquid ammonia tank safety risk management and control situation is grim. To actively implement the "opinions" requirements, Henan Energy Regulatory Office investigation and carefully combing the province's power industry the basic situation of major hazards, and actively carry out reconstruction work research initiative to communicate the situation with the Office of the Provincial Development and Reform Commission, the provincial emergency management, efforts to promote reconstruction work as soon as possible. "Notice" requirement province of the power generation enterprises should further enhance political stance, overcome difficulties, vigorously promote the major hazard (liquid ammonia tank) and Improvement, under the premise to ensure safe production, the province's coal-fired generating units and strive to 2020 in liquid ammonia tank renovation completed before the end of December. New coal-fired power generation projects should all use the technical route no major hazard.
Next, Henan Energy Regulatory Office will replace liquid ammonia around the transformation as an important safety regulation. For failure to complete the transformation of liquid ammonia replacement power companies, to be included in the list of key regulatory target, for there are significant risks or accidents in accordance with regulations to be strictly punished according to law, and urge enterprises to strictly implement the main responsibility to effectively prevent accidents, efforts to increase intrinsic safety level of the enterprise.
When the elasticity point of boiler tubes pressure exceeds the rated value, the need for chain protection: is shutdown, the system stops the combustion; fire mouth can also be varied, single-stage or two-stage combustion, can adjust the amount of oil, so that the step-down, to ensure safe operation of the boiler.
The inner (1) Cleaning Boiler
After opening the boiler winter operation we can see a lot of red fluffy black slag deposited on the bottom of the drum and the collection box, also seen in the sheet-like water residue adhered drum, water wall tubes and headers smoke the inner wall. The water wash residue can be chemically or mechanically. Conventional mechanical means is prepurge; a better cleaning effect, but the pot is limited space, especially for pyrotechnic impossible to use the boiler tubes. Methods of chemical cleaning with high pressure water boiling out mechanical grab combination is effective, to the extent that can meet heating surface qualities of the composition.
When the heating of buildings, heating area is also one of the issues to be considered, the size of the heating area directly affects the choice of elasticity point of boiler tubes capacity. For heating area, fast boiler technician summed up the relationship equation heating boiler heating volume and area.
