horizontal hot water boilerpulverized coal fired boiler
Recently, many users of the phone does not know how to shutdown after the steam boiler maintenance, boiler maintenance is very simple in fact, today we explain the steam boiler and horizontal hot water boilerpulverized coal fired 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
In recent years, vigorously promoting the "coal to gas" national project, in northern China have started to use gas horizontal hot water boilerpulverized coal fired boiler to provide heating and hot water for residential, hotels, hospitals, shopping malls and some entertainment.
Fast party independent R & D and manufacturing SZS Hose steam boiler having a low nitrogen, energy efficient, safe, easy to use, etc., using the waste heat of flue gas cascade, reasonably designed to maximize use of waste heat in the flue gas ; and the use of more than 95% of intelligent manufacturing equipment to ensure safe and reliable product quality; a number of warning device comes with boiler scale detection, smoke detection temperature, pressure sensing, all-round protection of the safe operation of the boiler.
Steam boiler buying guide and cautions because the steam boiler is an extremely easy to use and very clean and environmentally friendly boiler, so it is widely used in various fields, and very loved by the people. We buy when the steam boiler, it must first be checked in detail, to see its various parts is normal, and make sure it's good quality. From the perspective of traditional economic and energy structure of China's point of view, gas boilers due to the low one-time investment costs of popular people favored, especially in the rich coal resources, environmental protection and less demanding areas people prefer to select it. But in resource-poor coal, coal prices are not low areas of oil, gas and coal compared to a certain competitiveness. Another reason people like coal stove is easy to operate. But gas-fired boiler pollution: waste, emissions, waste water, "three wastes" and taste, governance Yijiao difficult (especially desulfurization, the current gas boiler desulfurization technology has made some achievements, but the high investment costs, operation complex, large area) from a social perspective should limit the use of gas-fired boilers. Gas boilers efficient, clean, environmentally friendly, without manual operation, only need to monitor, small footprint, no need to transport fuel, no need to deal with soot, due to natural gas combustion no impurities, no corrosion damage to boilers and related accessories, boiler long life , defined as 15 years, but basically long-term use. Is now mainstream boiler, natural gas is the environmental protection sector, the government vigorously promoted. Many have been using coal as the heat source of industrial companies now use gas stoves geographical mandatory requirements, it may be gas steam boiler threshold will be higher in the future to strengthen environmental protection efforts. Soot emissions from oil-fired boiler, although lower, but its emissions of harmful NOX, SOX gases are causing "photochemical smog" and acid rain culprit, to be governance as soot emissions as gas boiler control. Gas boiler with a small footprint, less pollution emissions advantages, but also the cost of the boiler room is not set up, the use of natural gas fuel prices, operating costs lower than oil-fired boiler. By comparison of three of the furnace, gas boiler not only set a lower cost and operating cost, and its social benefits are incomparable. Natural gas is the cleanest fuel, is the least polluting fuel emissions, gas-fired boilers will be the development trend of boiler final.
