Steam boiler wear and electric test pump DSY Henan fast boiler's water tube industrial coal steam boiler small series with you about wear and DSY electric test pump wear is one common steam boiler heating surface defects, boiler heating surface is arranged in the boiler the furnace and the flue, in particular a heating surface in the steam boiler flue vertical tail, by the long brush smoke, soot in the flue gas so that the wall heating surface wear thinned, so that heat from the flue gas scouring wall ironed a phenomenon known as wear and tear. Flow rate, the concentration of soot in the flue gas and the hardness of the tube bundle arrangement such factors as the wear rate of the heating surface of the steam boiler and the flue gas is related to the flow rate of flue gas wherein the greatest impact on the wear of the heating surface. Experimentally measured, proportional to the cube of the wear rate of the heating surface tubes and the flue gas velocity, it is necessary to effectively control the flow rate of flue gas. Leakage of the furnace wall, a partial wall flue ash, convection heating surface partially severe slagging will cause a partial flue gas velocity is too large, so that the heating surface tubes local wear increased, further, when the soot blowers work failure, high pressure steam steam heating surface tube will blow erosion, so that the wall thinning. Heating surface tubes often wear area is: cool ash, burner, bullnose, and close to Manhole sootblowing waterwall tube aperture; a lower portion of the flue gas before the steering tube heating surface vertical chamber; vertical tail horizontal heating surface portion of the second row of three tubes of the flue, the lower portion of the second three tubes, tube support edge portion of the clip, close to the furnace wall side of the rows of tubes and the individual tubes and the like projecting tube rows. Heating surface wear reduction methods are: to reduce boiler load, reducing flue gas velocity; burning coal quality, reducing the content of fly ash in the boiler flue gas steam; change bundle arrangement, a staggered arrangement to the line arrangement; Clear slagging and blocking flue ash, flue gas flow area increases; leakage reduction furnace wall; the installation of a shoe or the spoiler like. Abrasion test on the electric pump plunger hole set DSY electric test checking pump plunger sleeve (1) Check the DSY type. If the pump DSY electric test has passed the test on sealing ST-990 or the tester 3,375,375, the plunger sleeve is available. If the leakage is large, it is necessary to replace the plunger and plunger sleeve. (2) using the burr, coke, and high-expansion magnifying glass to check the amount of deformation of the bore. When the metering orifice is damaged, DSY i.e. electric test pump is not working properly. Do not attempt to clean with a wire, plug, etc., should be cleaned with a solvent. (3) Check the fuel oil channel as well as choking loose plunger sleeve for cracks. (4) Check DSY electric test pump plunger sleeve surface endless belt black area and Degree how damage flatness. Some electric test pump head end of the barrel nozzle sump has been canceled.

Gas-fired water tube industrial coal steam boiler, gas steam boiler buy several natural gas boiler should pay attention to, the purchase of natural gas boilers points to note from the National Development and Reform Commission learned that China's coal to gas steam boiler is widespread promotion of the implementation, will enter a stage of comprehensive reform. Xinjiang is about to be the most important work to complete the rectification, the rectification process of the Central Plains and northern regions also increased the intensity and speed of more than 40% of the coal-fired steam boilers, gas-fired completed the replacement of the country. At this stage there are a lot of users need to buy gas-fired boilers to meet the current national environmental policy, I would buy natural gas boiler problems and the majority of users to exchange views in order to buy the rest assured, with satisfaction. First and foremost do with the current coal-fired steam boiler model number and tonnage, boiler gas production and steam pressure that is being used enough, if we can current production, gas production and pressure on the election of equal size gas steam boiler, if not enough or barely enough, you need to choose a slightly larger model of boiler is the second point you are ready or the near future to expand the scale of production, it is necessary to recalculate gas production gas steam boiler, steam boiler of the gas production and future production scale be able to adapt. I met a lot of friends only consider the current, do not consider the needs of the next few years, thinking only meet the current needs on the line, such as the expansion of production and back. The ideas and practices to create a lot of trouble later, the life of a gas steam boiler is probably about 15, you do not have to change a few years, it is only used when processing a lot of losses. Furthermore, the replacement process is very time-consuming, to re-install the application procedures go again, and delayed production. Do not take precautions, you will regret it. The last thing to note is to ensure that the opening of the gas pipeline, if your area has no natural gas pipeline, is to buy a gas steam boiler also spend the. In determining the purchase of gas-fired, the first not to rush to the boiler transported to the site, first opened gas pipeline things well. A client told me: "I opened a mouth, a natural gas company gave me to do 100,000 a month just to run." So, first hit the point about the relationship, try to spend less money to natural gas mouth opened, then natural gas boiler shipped home.
Gas-fired water tube industrial coal steam boiler steam boiler gas to become the market trend is for countries to protect the environment, to control environmental deterioration and promote the steam boiler, gas steam boiler reconstruction is an arduous and urgent major project. Why the high price of coal to gas has changed, serious pollution of coal, especially in the past two years haze is particularly serious, mainly from coal to gas deal with environmental pollution, but the operating cost is much higher than gas. But the long-term development, economic development and should not expense of the environment, protecting the environment is everyone's responsibility. After gas steam boiler into a gas steam boilers, gas consumption is how much? Do not control coal, substantially in accordance with your boiler power to calculate, but one thing you need to think clearly, with the efficiency of gas-fired boiler efficiency gas boilers were quite different. So when you change 4 tons of coal boiler gas boiler, you can consider using a smaller gas-fired boiler. Coal to gas is a national policy not to install all right? Not installed, then it is possible, but now the country for gas-fired boilers is gradually ban, not to use, and if you do not choose coal to gas, then you need to select the coal to electricity, coal to heat pump etc., the gas must be slipping, these types of coal to the way you can compare each to see which is more suitable for their own gas steam boiler steam boiler gas into the benefits of what. Gas steam boiler includes a central water heater, new energy-saving, high efficiency stainless steel burner, electronic ignition pulse, a stainless steel coil heat exchanger, a strong discharge blower, intelligent control assembly elements, security devices and the like, the use of liquefied petroleum gas, natural gas, gas and other gaseous fuels, using the latest combustion technology design and manufacture of the heat exchanger, the thermal efficiency up to 95% water fast heating speed, high flow, with energy saving, easy to scale, automatic control without staff on duty, easy maintenance and so on. Economic and environmental performance far superior to the conventional type boiler modules may be stand-alone or in combination of line. Gas-fired steam boiler to save land resources, the same will not cause pollution like soot gas boiler. Gas boiler need to go through dust, slag process, complicated process, where the same water, gas boiler more environmentally friendly.

Unlike fire tube boilers, water tube boilers pass water through the tubes, which are then heated externally by hot gas from the furnace flue gas. The heated water rises into a steam drum, where it can then be reheated by a superheater to achieve even higher steam temperatures.Learn More
