Some knowledge boiler Introduction: boiler is an energy conversion device, the energy input to the boiler chemical energy, electrical energy, a boiler with a steam output of the fuel in the constant heat, high temperature water or organic heat carrier. Today introduced are several little knowledge about the boiler. 1, a way to improve the efficiency of the boiler A which:? ⑴ low heat losses: prevent heating surface fouling and coking, the rational use of the burner, controls the blower inlet air temperature, water temperature of attention to the impact, into the furnace to avoid excessive wind note impact milling system operation; ⑵ mechanical incomplete combustion to reduce heat loss: rationally adjust the fineness of pulverized coal, the excess air ratio control of appropriate, attention combustion adjustment; ⑶ quality assurance fired boilers; ⑷ reduce soda losses: guaranteed boiler quality water supply, installation and maintenance to improve the quality of the steam separator means, to maintain the operation of the boiler load, the water level, steam pressure and other parameters of stability, so that the boiler water separation apparatus operating under normal conditions; ⑸ index management adhere to the small boiler. ? What are the reasons boiler fire answer: ⑴ low boiler load, low temperature furnace, combustion temperature, combustion oil investment is not timely; ⑵ poor coal quality, low volatile matter, ash is too large; ⑶ air volume to adjust properly, once too high wind speed, wind powder imbalance, the excess air ratio is too large; ⑷ excessive negative pressure maintaining furnace; ⑸ bunker powder level is too low or fallen powder to the powder to make the powder unevenness; ⑸ large depression coke furnace, disturbances in the furnace is too large; ⑹ ash, coke playing time is too long, especially large caused by cold air leakage into the furnace temperature drops to a low load; ⑺ blast furnace tube, a large number of soft drinks into the furnace; ⑻ fire protection action; ⑼ device malfunction, such as sending, fan, tripping of mill, Auxiliary disappeared.
Car accessories types of complex processing, such as the interior wall Peng, floor, seats, instrument panels, sound systems, many processes required in a high temperature environment, the temperature becomes optional metrics wind Visteon hot water boiler. It is reported that Dongfeng Visteon existing boiler equipment can not reach the growing production needs, the introduction of fast boiler production of two parties often piezoelectric hot water boiler (CWDR1.8-95 / 70-II) in 2017.
Risk factors for gas diesel fired steam boiler for bioreactor steam boiler gas boiler risk factors get in the industrial field has been widely used. However, the safety of heat transfer oil boiler has been neglected. Safety heat oil boiler is not only related to the normal operation of the plant, also related to the safety and efficiency of the staff of the enterprise. security issues heat transfer oil boiler should be aroused widespread concern in the community, its vital security issues. pot body portion and a body portion of the furnace for gas-fired boiler, the occurrence of physical experience pot explosion. for liquid boiler, the boiler combustion flame in the furnace section, if the boiler burning coal, there will be a burning fire, gas and fuel boiler chemical explosion. gas boiler is a highly dangerous material having high temperature, high pressure, flammable, explosive and other characteristics. in practice, these reasons, we could cause some problems negligence or illegal operation, so inevitably lay hidden dangers. first, you must ensure that safety heat transfer oil boiler. in use of the device, the device needs to be checked regularly to ensure that the heat transfer oil boiler heating system in good shape , The strength of the wall of the pressure equipment and devices to check that there is no problem; Second, employees must strictly follow the instructions Due to the special nature of the gas steam boiler, inflammable and explosive materials pose a security risk, the operator must be trained. familiar with the device structure, operating strictly in accordance with the articles of association; third, to ensure that the gas does not mix with water vapor gas steam can not be mixed with low-boiling substances and explosive substances, otherwise the consequences could be disastrous.
Recently, many users of the phone does not know how to shutdown after the diesel fired steam boiler for bioreactor maintenance, boiler maintenance is very simple in fact, today we explain the steam boiler and hot water boiler shutdown after: After the steam boiler maintenance shutdown method how maintenance. Since the cause of boiler failure or power shutdown required boiler, a steam boiler before travel should stop combustion boiler, the boiler slowly lowering the temperature until no pressure boiler, should pump before shutdown, induced draft fan and turn off the blower. After the maintenance shutdown home for boiler, furnace divided into external corrosion and home for the pot. Pot corrosion enjoying, enjoying their home for two kinds of wet and dry selected based on the length of shutdown time. When long-term disabled boiler, furnace should be paid close attention to external corrosion problems take care of themselves. First, the boiler shutdown cooling is necessary as far as possible completely eliminate fouling and ash grate heating surface of the upper, the lower portion of the furnace. Then have to adhere to certain natural ventilation flue. Under normal conditions, should be placed to dry moisture-proof agent in the furnace, flue. The dry quicklime as used, the furnace or the flue gas per cubic meter of ordinary should be placed about 3kg. After placing all the ventilation should be tightly closed doors. Lime powder to change after change. Such as boiler rooms in low-lying position, the air during shutdown severe flood tide, the method should be used regularly and placed a small fire to dry dry agent phase separation. If the boiler boiler long time, in order to thoroughly clean the soot topcoat red lead oil furnace or other metal surfaces in the anti-corrosion paint. As for the way home for corrosion inside the furnace shutdown, the shutdown Yaoan the length of time to be. Under normal circumstances, no more than one month shutdown of the available wet home for a month or more should take care of themselves dry. Dry to pay attention when enjoying the following questions: Do not dry agent in direct contact with the metal outer boiler, can be housed in a container such as an iron plate; dry agent after standing, for shutting the hole and the other hand hole cover, the vapor, the water pipe necessary to cut off valve; variant lime powder should be replaced. While enjoying wet, to pay attention to boiler water condensate is preferably used, followed by the available existing boiler water, demineralized water again; after adding the base, with a slow fire boiler water is heated to 80 [deg.] C to 100 the pressure rose to 0.2 maintenance after 0.3MPa 2 to 3 hours, so that it reaches the furnace circulating water alkalinity balance, pressure is reduced, then fill the boiler water, a certain gauge, and continue to adhere to this pressure throughout the home for alkalinity should be regularly tests, decreases should be added at any time; in winter, wet enjoying pay attention to antifreeze, especially the local sewage channel and economizer; before re-use should release all the pot boiler lye, best prepared sump, in order to facilitate further use. At the same time should be rinsed with clean water. The performance characteristics of coal, oil, gas steam boiler
