If there is damage in the supposed gas-fired? Detailed inspection is important, as the key oil regulation. According to the conditions and time management, gas-fired, people can effectively damage inspection program. The application of oil, people strictly control the particle size of coal and dolomite. Should strictly control the particle size of bed material. Should be addressed furnace waste. To be able to solve the waste furnace after discharge. Natural gas 0 7mw 70mw automatic coal hot water szl boiler should be installed in areas where the application of calories, easy to install. Heating pipe can not be too long. It should have a good cable jacket. Water piping for an output from moderate to tail skew. Water resources to be equipped with a pressure regulating valve. As sewage gas, natural gas boiler chimney should widen to the outside, a heating furnace entrance width 1.5 to 2M. If you want to reduce the harm to the water wall tube can be appropriately regulate air pressure and wind speed and reasonable to reduce damage to the water wall. Inspection time is generally standby shutdown or shutdown condition. To check top head comprising the furnace wall is damaged, leakage of the furnace airtight and smoke. In the damaged condition requires immediate repair and welding, in order to ensure that no problem in the operation of steam boilers. Typically, before the ignition of gas-fired, fossil fuels must be added the charge in the combustion chamber, fossil energy and raw material-circulating bed material and gas in the wind, the strength and intensity of the flow down completely integrated. Bottom wind equipment, up for the core area. Exercise our powers in a ring outside the region along the furnace wall water swimming down, thus increasing the waiting time of coal particles in the furnace. Mineral particles, many of the ash and soot particles with a lot of fly ash, this resulting in rapid deterioration of the waterwall tubes continuously, so that damage to the wall thickness becomes soft, resulting in damage.
Recently, many users of the phone does not know how to shutdown after the steam 0 7mw 70mw automatic coal hot water szl boiler 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
Main steam 0 7mw 70mw automatic coal hot water szl boiler temperature abnormal phenomenon of how to do 1, main steam temperature anomalies alarm. 2, the rapid variation of the main steam temperature, a secondary damper frequently significantly reducing water operation. 3, starting superheat outlet steam separator above or below normal. 4, if the steam with water, the unit will water shock occurs. 1 reason, the fuel and water supply imbalance, the separator outlet temperature abnormality. 2, coal combustion conditions change or affect, such as excessive load lift; and pulverizing mill administration system abnormality stop; means automatically increase or decrease the failure rate is too large amount of wind and the like. 3, the central flame furnace changes, such as the bottom seal damage, W and inadequate flame downstroke. 4, the control failure by warm water, warm water flow rate reduction is abnormally reduced or increased. 5, feedwater temperature mutation. 6, does not match the wind coal. 7, the secondary combustion heating surface. 8, furnace coking or fouling seriously. 9, heating surface leakage squib. 10, flue gas damper opening degree is not normal. 11, coal sudden change occurred. 12, the uniformity of the powder feeding substantial change occurs. 1 process, failure caused by unit coordinated coal - water ratio should be immediately released coordinate offset, in accordance with the current load demand, with reference to the start of the steam superheat separator, and adjusting the amount of fuel corresponding to the amount of water, with one, two main desuperheating water rapidly steam temperature control in a normal range; when the coal - water ratio should avoid imbalance after coal and water while adjusting; when coal - water ratio is adjusted to further adjust the load after a relatively stable; contact maintenance processing timely. 2, when the water supply system fault condition occurs a significant disturbance furnace should pay attention and automatically coordinated working conditions, so as not to manual intervention, when not working properly coordinated and automated, should be manually adjusted, stable water flow, referring to separation according to the water flow steam superheat, the adjusted amount of fuel, with a secondary spray water rapidly controlling the main steam temperature within the normal range; contact maintenance processing timely. 3, due to rapid changes in load caused by the load change rate should be adjusted; load change caused due to protective operation or the like caused by heat load to be quickly adjusted to maintain the boiler pressure of the main steam stability. 4, by warm water automatic dysregulation, should be appropriate Save warm tone is switched to the manual may be an intermediate point of the feedwater control system be corrected for temperature if necessary, or the feedwater to switch control to manual control, due to lower lifting and lowering the load speed to prevent steam temperature, promptly contact a service process. 5, the boiler furnace cause severe fouling and coking of the main steam temperature anomalies can be corrected by an appropriate degree of superheat outlet steam separator start, adjust, and in a timely manner and the furnace heating surface sootblowing. When the platen superheater sootblowing or superheater outlet temperature is still above normal and a secondary reducing water damper fully open, to check the furnace and the combustion air distribution system is normal, the checking process to reduce still overtemperature unit load. 6, flue gas damper adjusted to an appropriate opening degree. 7, if the bottom seal after losing back to normal immediately. 8, to strengthen the turbine expansion, differential expansion, axial displacement of the shaft vibration and bearing temperature monitoring, if abnormal, the process according to the corresponding regulations. 9, after the above measures, if invalid, should immediately drop the load process. 10, in front of the main steam temperature main steam 50 ℃ drastically reduced within 10 minutes, should an emergency stop.
