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.
Gas-fired fired steam boiler steam boiler which has the advantage compared to ordinary? With the fog and haze over the ongoing frequent occurrence, people on the importance of protecting the environment is also a new understanding of traditional coal-fired steam boiler is also limited policy, many basically let the big cities now use coal-fired steam boilers, and many areas have begun to work coal-fired boilers, low gas and steam energy saving my company's research production of boilers, environmental protection, operating costs, welcomed by the market. Energy conservation, environmental protection relative to conventional convenience I produced gas steam boiler Gas steam boiler advantages are: 1, 0.5 tons of gas steam boiler steam from the ignition to just 2-3 minutes, while the average gas steam boiler needs more than 20 minutes. 2, gas steam boiler compact, small footprint does not need to build the boiler room. 3, and does not require government departments to deal with, because the normal water level of the water capacity of only 27 liters of gas steam boiler is not within the range of technical safety supervisory inspection of the boiler, the boiler does not need professional workers, a key to start fully automatic operation. 4, heating area, there are supporting economizer 2T, increasing the heating surface of the boiler, provide the working efficiency greatly save fuel. Low cost: Compared with the fuel gas steam boiler, electric heating steam boiler can be reduced by 30% of the fuel, a steam boiler heated area can reach 92%, coupled with a supporting economizer heat generated by the boiler can be sufficiently absorbed , significant savings in operating costs of the boiler corresponding to the call of the national energy saving, gas steam boiler new products in recent years come to the fore, not only do energy conservation, which also meets the requirements of industrial production of thermal energy, ordinary steam boiler replacement product.
There are build on the control of emissions of nitrogen oxides boiler in order to achieve NOx emissions from combustion boilers of less than 30mg / m3, reached the world advanced level. Austrian far low nitrogen fuel gas boiler Staged Combustion Process of the invention into three regions in the furnace combustion techniques, primary combustion zone into the small portion of the fuel, the fuel required for the combustion air into the furnace in stages, the air volume of 80% left and right into the main combustion zone, the primary combustion zone of the upper (downstream of the flame) of the fuel injected into the secondary combustion and the formation of Carrying out a reducing atmosphere in the third zone into the combustion air required Further, complete burnout process. To create a discharge for the control of nitrogen oxides boiler fuel and air in order to achieve staged combustion gas boilers achieve emission limits is very basic configuration of environmental protection facilities, comprising an electrostatic precipitator or bag filter, gas boiler efficient desulfurization apparatus, a selective catalytic reduction (SCR) or selective non-catalytic reduction (SNCR) and the like denitration apparatus. All aspects of air pollution sources to install automatic monitoring facilities, fired steam boilers and networking with the environmental protection department, install a distributed control system (DCS system), real-time monitoring of gas boiler pollutant emissions. All-premixed combustion technology implementation of a number of Austrian far improved combustion technology after years of build have on the control of emissions of nitrogen oxides boiler fuel and air in order to achieve staged combustion. This technique can be gas boiler NOx emissions chain by 70% -60%. At present, to solve pollution problems of small and medium industrial gas boilers have four energy saving way. First, clean fuels covered by the remaining gas boilers, boiler premix combustion technology implementation of a number of improved combustion technology after years of Austrian far as natural gas boilers, biomass boilers and so on; Second, the rising water boiler technology.
Diqing in Yunnan Nonferrous Metals Co., Ltd. mainly engaged in Pulang copper mining, site selection, sales and other items. As we all know, in the copper smelting process, it consumes a lot of electricity and thermal power resources, which account for most of the hot water consumption. Combined with the actual demand Diqing company, to provide fast Boiler 1 stage electric heating hot water boiler of 2.1MW.
These impacts were estimated assuming electricity is generated in coal-fired power plants, steam is produced in natural gas -fired industrial boilers, and natural gas is used as the auxiliary fuel in incinerators and flares.Online chat
