Recently, Henan Province issued the "2019 Henan ecological ideas and points", as follows.

1, the implementation of "winning Blue Sky Battle three-year action plan," "Henan tackling pollution prevention three-year action plan." We continued to do a good job in controlling coal, discharge control, train control, oil control, dust control, control burn "six control" based on the prominence of coal consumption reduction, optimize the industrial layout, transport restructuring, diesel trucks governance, urban dust remediation industrial upgrading green, clean heating construction, ecological expansion speed, enhance monitoring capacity, heavy pollution 10 iconic battles weather control and so on.

2, 2019 to promote the implementation of planning, environmental impact assessment and other "unified" requirement, in principle, then add the non-power sector coal consumption province-wide project to promote the transformation of shutting down coal-fired units and behind the irrational total of 1.5 million units kilowatt. Promote political urge the main town of coal units cleared and the main city of Luoyang coal units basically cleared. Do a good job clearing the continuing dynamic "scattered dirt" comprehensive improvement of enterprise and small coal-fired boilers. Township units continued to carry out an intensive investigation, the implementation of inventory management, network monitoring, inspections normalization mechanism, to treat small coal-fired boilers, found together with the ban.

3, already verified "messy dirty" business, in accordance with the principles of the rule after the first stop, the implementation of classification prosecuted. Do not meet industrial policy access, industrial layout planning, outdated equipment and technology, and no hope of treatment compliance, implementation of the "two off three clear"; the inclusion of the relocation of integration classes, in accordance with the principles of large-scale development, relocated to the industrial park and the implementation of upgrading; upgrading the inclusion of the class, set the industry benchmark, the implementation of cleaner production transformation, to raise the overall level of pollution abatement.

4, advancing the steel, aluminum depth treatment with carbon, cement, glass, coke, aluminum and other key industries. Deepen industrial enterprises fugitive emissions control, industrial furnaces special treatment, comprehensive treatment of industrial boilers, foundry industry depth governance, strengthen the petrochemical, chemical, packaging, printing, industrial painting and other key industries of volatile organic compounds pollution.

How do I care after the 6 4 bhp-5 bhp steam boiler shutdown method Recently, many users did not know how to call maintenance shutdown after steam boilers, boiler maintenance is very simple in fact, today we explain the steam boiler and hot water boiler after shutdown 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. . Enjoying while 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 the pressure rose to 100 0.2 when the 0.3MPa to maintain 2-3 hours, alkalinity boiler water circulated reach equilibrium, reduced pressure, then filled boiler water, a certain gauge, and continue to adhere to this pressure throughout the home for, alkalinity should Regular testing, 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 then. At the same time should be rinsed with clean water.

Gas boiler price related factors and their dust: the gas boiler in the boiler, which is one of the website products, and further comprising a gas hot water boiler, gas 6 4 bhp-5 bhp steam boilers, gas oil furnace three. Therefore, it is necessary from a whole, to know and understand, so that we can help further their specific products, and at the same time, to increase the amount of their own knowledge in this area. 1. gas boilers and electric boilers, which one is better? Gas boilers and electric boilers, boiler compare the two, then, can not say which one is better, because there is no comparable. I can only say, under what circumstances, what kind of boiler more appropriate. Moreover, both the boiler, there is a range of different applications and features. 2. Gas boiler room, whether it takes 24 hours on duty? In addition, two tons of gas boiler, its price is mainly related to what?

Talk about the overall structure of the furnace boiler boiler boiler and auxiliary equipment, including two parts. 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. Today, we are concerned that the furnace boiler. Also known as boiler furnace combustion chamber, fuel combustion for space. It solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as the fire-bed furnace. Solid fuel liquid, gas or pulverized, is injected into the furnace fire chamber may be referred to as a combustion chamber of the burner, also known as the furnace fire chamber. The coal particles and air hold it was boiling point of combustion, the furnace and adapted called inferior fuel combustion fluidized bed furnace, known as a fluidized bed furnace. An air flow so that the coal particles rotated at high speed, and strong burning furnace called cylindrical cyclone furnace. Boiler 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. In addition, the 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.
