Water wall boiler tube leak or burst phenomenon how to do 1, the normal water flow is not greater than the steam flow. 2, the furnace pressure transient and unstable prejudiced. 3, tube leak detection alarm device. 4, the furnace may not tight at the outward discharge gas and water vapor, and a significant leakage sound. 5, the main steam pressure drop. 6, boiler combustion dark flame instability caused by severe boiler fire. 7, when the induced draft fan is automatically cast, abnormal static vane opening is increased, the current increases. 1 reason, the presence of water wall tube material defects or post-production, the installation of the damaged pipe, poor welding quality. 2, the inner tube fouling overtemperature. 3, the inner tube corrosion. 4, water wall wear. 5, the long-term high load operation, furnace coking, coal sulfur corrosion caused by high temperature water wall. 6, improper combustion, flame deflection. 7, in the possession of bad foreign body, the water cycle. 8, the wall of the long-term over-temperature operation. 9, the temperature difference between waterwall tubes, mechanical stress crack. 10, the normal exit or drain sootblower steam punctured tube. 11, smashed chunks of coke furnace water wall tube or serious explosion occurred, resulting in water wall tube suffered external damage. 12, boiler overpressure long run. 13, the boiler starts to heat up, step-up too fast. 1 process, the leakage should try waterwall tubes outage. The leakage is not serious, while still capable of maintaining operation, note that each of the automatic operation when the device, if not normal, it is cut immediately to the manual, if necessary, may be down, down-load operation. Closely monitor the development trend of damaged parts, good accident anticipation, application shutdown as soon as possible. 2, if the leak is serious, the bursting point temperature after a sharp rise in quality work, leading to serious over-temperature wall, unable to maintain the normal operation of the boiler or threaten the safety equipment, emergency shutdown provision should be processed, when the steam temperature to protect the action value, the protection does not move, should immediately hand MFT. 3, note that the operation of the electrostatic precipitator, to strengthen the inspection checks, to prevent fouling, and the electrodes ESP hopper, pipes and the like plugging air preheater ash. 4, after the shutdown, should retain ID fan, the furnace pressure is maintained constant, there is no discharge to be stopped after soda ID fan.

What is the reason for integrated steam boiler manufacturer in china explosion? Boiler itself is flawed: the pressure component aging, strength weakened, or leakage, corrosion, deformation, scaling and other defects can not be timely maintenance and eliminate hidden dangers, but let the disease run with the boiler and so on. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. Therefore, we must carry out regular inspection of boilers in accordance with national requirements. 3. poor management, furnace workers irresponsible or low levels, lead to misuse. Therefore, furnace workers must obtain a certificate as required. None of the above is the main reason for the actual boiler explosion. In actual operation, the most common situation is that the boiler add cold water and drying, which is very dangerous. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. This is also the operators need the most important thing vigilance. There may be debris blocking the pressure cooker vent, causing the pot to continue to increase pressure, excess pressure can not be discharged to reach the pot of strength, can withstand the pressure will naturally explode, of course, does not rule out the cause of pan itself. Substandard quality, tank leaks, inadequate exhaust usually cause an explosion. Therefore, before use, carefully check the vent is smooth, not to violate the specification and taboos, without any danger.

What are the overall structure of the boiler boiler structure includes two major boiler and auxiliary equipment. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Boiler body is in two main parts and drum furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. The furnace cross-section is generally square or rectangular. Combustion fuel to form a flame in the furnace and high temperature flue gas, so the hearth around the furnace wall is made of refractory material and insulation material. On the inner surface of the wall of the furnace waterwall tubes often laid, it will not burn both protect the furnace wall, and absorb a large amount of radiation heat of the flame and the high temperature flue gas. Furnace design needs to fully consider the characteristics of the fuel used. Each boiler should be fueled with the original design of the fuel. Boilers running economy and reliability are likely to vary greatly reduced when using the characteristics of fuel combustion. And the natural circulation drum is repeatedly forced circulation boiler receiving feedwater to the economizer, the coupling cycle and supplying saturated steam superheater cylindrical vessel. Simplified drum made from high quality steel plate, is one of the heaviest components of the boiler. The main function of the water storage drum, a steam separator, brine and water excluded pot sludge in operation, to avoid the boiler water containing a high concentration of salt and impurities entering with the steam superheater and a steam turbine. Internal drum means comprises a moisture separator and a steam cleaning apparatus, water distribution pipes, sewage and dosing equipment. Wherein the effect of soda is separated from the water wall by means of saturated steam and water to leave, and to minimize the steam carried fine water droplets. Low pressure boiler used as a crude flap and slit baffle separating element; above except pressure in the boiler is widely used for various types of rough separation cyclone, but also with blinds, steel mesh plate or the like are vapor further separation. The drum is also equipped with water gauges, safety valves and other monitoring and protection facilities. In order to improve the design and performance assessment, often have to go through boiler thermal balance test. Direct methods to calculate the thermal efficiency of the boiler is called n-efficient use of energy balance, the heat loss from a variety of methods to counter the counter balance called computational efficiency. When considering the practical benefits of the boiler room, boiler thermal efficiency not only look, but also taking into account the energy consumed by the auxiliary boiler. Fuel per unit mass or unit volume of complete combustion, calculated according to the chemical reaction called the theoretical air quantity of air required. In order to have more opportunities to the fuel in contact with oxygen in the furnace combustion, the actual amount of air into the furnace is always greater than the theoretical air amount. While air can be reduced into a multi incomplete combustion heat loss, but the heat losses will increase, also exacerbate corrosion of sulfur oxides and nitrogen oxides generated. We should therefore seek to improve combustion technology, as small as possible in order for the excess air ratio in the furnace so that complete combustion. Dust contained in the boiler flue gas (including carbon black and ash), sulfur and nitrogen oxides are air pollutants, which can achieve emissions targets environmental regulations when unpurified indicators several to several tens of times. These substances emissions control combustion pretreatment, improved combustion techniques, dust removal, desulfurization and denitration. By means of a high chimney stack can reduce the concentration of pollutants in the atmosphere of the area. Flue gas dust removal force used gravity, centrifugal force, inertial force and acoustic adhesion, static electricity and the like. Is generally used for separating coarse particles gravity settling and inertial force, centrifugal separation is often used dust bag filters and electrostatic precipitators having a high dust removal efficiency at higher capacity. Wet venturi - water film adhering water film droplet precipitator ash, high collection efficiency can absorb gaseous pollutants. Since the 1950s, people strive to develop the comprehensive utilization of ash, harm into. The manufacturing cement, bricks and building materials such as concrete aggregate ash. Since the 1970s and from the fly ash cenospheres extracted as a fire-resistant insulation and other materials. Future development will further improve boiler thermal efficiency of boilers and power plants; reduce equipment cost per unit of power boilers and power plants; enhance operational flexibility and level of automation of the boiler unit; develop more varieties to suit different boiler fuel; and improve boiler unit the reliability of operation of the auxiliary equipment; reduce environmental pollution.
