Small gas steam boiler gas boiler works as the name implies refers to the fuel gas boilers, gas boilers and oil-fired boiler, electric boiler compared to the most economical, most people have opted for a gas-fired boiler steam boiler facilities, heating, bath with . Gas boiler comprising KS-Q water gas boiler, CLHS (CWNS) gas coal fired hot water boiler suppliers, LHS (WNS) gas steam boiler and the like, wherein the gas comprises a gas hot water boiler heating boilers and gas boilers bath, with the state "natural gas "project implementation, gas boiler gradually become the people's choice. Evaporation general industrial boilers are relatively small, all below 40, to about 10-35, mostly, but also the use of industrial boilers and boiler power plant are not the same, the main industrial production boiler steam and hot water requirements index is not very high, Some general-purpose industrial steam is used, for example, a lot of steam seal the furnace, hot water steam heating and other uses, in the form of industrial boilers, furnaces most mostly a chain, because chain boiler technology is mature, simple and reliable construction, also automated, etc. factors, by the majority of users of all ages boiler. Chain has chain structure of the furnace grate, coal gate, eagle iron, the furnace, the slag discharge pipe, water wall, the upper and lower header, superheater (steam boiler there), the convection tubes, upper and lower collection tank (also known as drum), province coal filter, air preheater, and corresponding systems and auxiliary pumps and fans, as well as instruments and other devices. The structure is characterized before and after the formation of more water wall furnace arch, it is to promote ignition and combustion, the combustion more complete. Grate bin wind, the wind can be equipped according to the amount of coal burned specific distribution of silos. There are pulverized coal power plant boiler circulating fluidized bed boiler and the main in an amount greater evaporation gas boilers, high efficiency, structure and chain furnace different, similar to the structure of pulverized coal and circulating fluidized bed boiler, but different principles, coal powder and circulating fluidized bed boiler furnace are used with a bed of air holes, the primary air into the drum by the bed, secondary air into the furnace to carry the pulverized coal combustion mixture is formed, separated by the cyclone after burn unburned complete coal combustion again, fluidized bed boiler pulverized coal stream is formed form, better than pulverized coal fired combustion, combustion, low temperature combustion is also achieved, reducing the emission of nitrogen oxides. Fuel oil-fired boiler is fuel (such as diesel, oil, kerosene, etc.), fuel gas-fired boiler to gas (such as natural gas, city gas, methane, etc.), depending on what fuel boiler combustion devices called burner, gas burner configuration called boiler gas-fired boiler, oil boiler burner configuration called oil-fired boiler, oil-fired boiler and gas boiler difference is that what fuel burners.

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 coal fired hot water boiler suppliers 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
