75 ton circulating fluidized bed cfb boiler
Hot water 75 ton circulating fluidized bed cfb boiler up and running before the inspection process: A boiler for hot water boiler which, I believe we will not feel strange, because it is the site of the product, but also a common and popular types of boilers, so based on these two points, it is necessary to carry out its awareness and understanding, so that we are familiar with this kind of boiler, in turn, to increase the expertise in this area, and should know how to correctly and reasonable use. 1. hot water boiler, before the start of its examination process, specifically what is? Before the start of the hot water boiler inspection process, the specific terms, it is as follows: Step one: each boiler safety accessories, thermal instrumentation and electrical instruments, such as checks, whether it is complete and intact, to work properly. Step two: hot water boiler to the respective connections, weld lines and the like check for leaks and so problems. Step three: sewage pipelines, water pipelines and return lines to check whether it is smooth. Step Four: supply and expansion tank filled with water, and the line voltage is checked whether the voltage is 380V. Toggle if so, whether controlled within 5%. Step Five: open the manual valve, and a water supply valve and a return valve. After that, it is to start the pump and burner and check whether it is operating properly. Step Six: boiler heating system water filling operation, in order to discharge air in the system clean without any residue.
Causes and prevention of chemical plant 75 ton circulating fluidized bed cfb boiler 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.
Circulating fluidized bed 75 ton circulating fluidized bed cfb boiler technology is an advanced technology which circulating fluidized bed boilers usually adopt. ZG Boiler is a circulating fluidized bed boiler manufacturer in China with more than 70 years’ history and we can design and manufacturer circulating fluidized bed hot water boiler for heating, circulating fluidized bed boiler for power plant and our 116 MW circulating fluidized bed boiler is the for its high efficiency and energy saving from National Development and Reform Commission. And the circulating fluidized bed technology is becoming more and more mature.
In October 2016, my company and the China Dunhuang International Hotel signed a ZWNSL2.1-1.0 / W-Y.Q vacuum condensing gas hot water 75 ton circulating fluidized bed cfb boiler to provide heating and hot water for the hotel. The boiler implementing the response to the national policy of environmental protection requirements and local environmental protection departments on a series of low nitrogen emission standard boiler requirements, in terms of design, manufacture, installation and other sectors have strict checks to ensure that the boiler safe and stable operation.
