Causes and prevention of chemical plant types of package boiler ppt explosion: causes and preventive measures chemical plant boiler explosion, the explosion occurred in a chemical plant boilers, analyze the causes and preventive measures boiler explosion in a chemical factory, it can all be on the news or on TV saw the explosion of a chemical plant in the news, resulting in a double loss of personnel and property. So, we need to reason and the boiler explosion prevention measures are to have a detailed understanding of. Overpressure rupture boiler operating pressure exceeds the agreed maximum working pressure, the stress exceeds the limit stress component data. Overpressure conditions often fail due to safety relief devices, pressure gauge misalignment, overpressure alarm equipment failure, severe water shortages caused by improper handling incidents. Heat Failure burn hot plate, component damage caused strength decreases. Usually dry because of water shortage. Fouling too thick, there is a pot of water caused by asbestos rubber pull people off other foreign matter such as grease or drum within reason. Caustic embrittlement due to corrosion failure of the element strength. Crack and split by the groove elements alternating stress effect, produce fatigue crack, and the combined effect of etching, opening into a groove-shaped thinned. Water hammer due to damage caused by improper operation of the system soda water hammer, the pressure receiving member was strong effect of additional stress and failure. Repair, renovation unreasonable formation of boiler explosion hazard. Congenital shortcomings planning mistakes, force structure, terms of thermal compensation, the water cycle, timber, strength accounting, security facilities and other serious fault. Making mistakes, wrong information, not according to the drawings, the quality of low-quality welding, heat treatment, such as hydraulic test process standards fault caused. What measures can prevent chemical plant boiler explosion it? Avoid over-pressure approach: a reasonable set, timing alignment, proper security protection in width, pressure gauge, water table; avoid overheating approach: a reasonable set, monitoring, repair, wash water table, avoid water, avoid fouling and foreign object into the grease drum; avoid corrosion measures: water quality objectives should comply with national regulations and standards relevant skills, strengthen the repair and maintenance; avoid groove crack: not cold and hot temperatures, reducing the alternating stress, easy to see from the slot position, timely repair; avoid water hammer: note hydrophobic soda system, adhere to the water level stable. No anomalies water level; strengthen inspection planning, production supervision and inspection repair, renovation of the review, to eliminate potential accidents.
Natural water, very pure even seemingly clear tap water contain various dissolved salts in which calcium and magnesium salts. That is the hardness of the material, it is causing a major source of steam types of package boiler ppt fouling. Due to the scale of great harm to the steam boiler, thus removing the hardness, the primary task is to prevent fouling of the steam boiler water treatment, dosing treatment may be achieved by chemical treatment outside the pot or pan.
Dengzhou gas hot water types of package boiler ppt which company is good for the present, domestic gas hot water boiler supplier, depending on the load, each with their own strengths sample gas hot water boiler. Do not save people ask questions to determine whether the gas hot water boiler in question covers what professional standards. Generally in order to accurately choose suitable for use in our company's gas hot water boiler, such as the number of navigation which should know the following: First, the thermal efficiency of gas hot water boiler Second, gas hot water boiler began to contribute to the speed of three gas hot water boiler rated load four, a group of several types of navigation above the gas hot water boiler, gas hot water boiler is enough to get most of the usual non-compliance, and most certainly not up to thinking, from a number of navigation, can understand 1 gas hot water boiler set whether or not there is stability problem, obviously, gas hot water boiler election day, pick a most suitable to our company, the high cost of gas hot water boiler is the main thing.
After the types of package boiler ppt put into use, such as the hotel responsible person to give us feedback: fast boiler advanced product design, simple and intuitive operation, the most critical is energy saving, low NOx emissions, can be used in the Beijing area. Compared with other boiler brands, fast Boiler made us worry. --customer feedback
