coal fired 21 steam boilers fire tube

Do you know what it is gas energy saving boiler gas boiler energy-saving and environmental protection Many customers do not believe, how coal energy-saving environmental protection? Zheng Boiler Group today for everyone to analyze environmental history of the gas boiler. Energy saving gas boiler pot Zheng Group production of a new product, a gas coal fired 21 steam boilers fire tube. Energy saving gas boiler pot Zheng Group production of a new product, a gas steam boiler and gas hot water boiler, gas steam boiler models which are mainly DZL steam boiler gas chain, DHL chain gas steam boiler, SHL chain gas steam boiler SZL chain and energy-saving gas steam boiler and circulating fluidized bed boilers. Zheng pot boiler gas saving and environmental protection are "perfect green and environmentally friendly boiler boiler auxiliary boiler machine environmentally friendly application process installation service" model pioneered go on the road "environmental effects Enhancements". In addition to these types of environmental protection boiler, auxiliary equipment, environmental protection is also an important part of the environmental process. Energy saving boiler fuel gas separation efficiency as high as 97.97%, combustible low-quality coal, good desulfurization effect, can significantly reduce sulfur corrosion of equipment, in favor of low quality coal combustion, coal adaptability strong. Boiler fan low energy consumption, high economic efficiency, and can effectively avoid the fan big horse car phenomenon. To more than dust and coal in the coal auxiliary, not only an automatic cleaner, convenient safe, maintenance.

April 8, 2019 China International Corrugated exhibition in Shanghai New International Expo Center, such as about the opening. Fast boiler as China's "most influential brand of industrial boilers," was invited to participate in the exhibition.

Small electric coal fired 21 steam boilers fire tubes What are the benefits, features? First, electric and coal, oil steam generating comparative advantages and disadvantages: advantages and disadvantages of coal: Advantages: coal is the most economical energy per kilogram of coal can produce more than 5,000 calories, can produce about 6 kg steam (theoretical value). Both economical than electric, fuel oil and natural gas. Disadvantages: 1, low efficiency, although theoretically per kilogram of coal can produce more than 5,000 calories, but due to the limitations of coal-fired boilers and human factors affected the Boilermakers, the real heat of the steam is converted to produce much smaller than the theoretical value, the heat utilization rate of around 60%. 2, can not do automatic control, if the device is not continuous steady steam steam that instant steam consumption fluctuations, the steam produced by the boiler with the steam in the bottom of the valley steam equipment can only let go waste. 3, need specialized operators, high labor costs. 4, do not meet the requirements of modern environmental protection, to ban small coal-fired boilers is the trend. The advantages and disadvantages of fuel: fuel meets the requirements of environmental protection, the state has not been expressly provided, however, based on current oil prices, its economy has ceased to exist. Per liter of oil can produce more than 18,000 calories, about 60% utilization, we can produce about 10 kg of steam. Which produce one ton of steam costs around 800 dollars (at current prices). The advantages and disadvantages of heating: Cons: Because electricity is converted from the other sources of energy, so the relatively high price point, once electricity can produce about 1.5 kg of steam. Calculated to produce 1 ton of steam costs about 400 yuan or so based on the current average domestic electricity bill. More expensive than coal.

Steam boiler wear and electric test pump DSY Henan fast boiler's coal fired 21 steam boilers fire tube 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. Henan is committed to fast boiler steam boiler manufacturing, product quality, reasonable prices and widespread industry praise, if you have any needs, please contact us!

Coal-Fired Boiler - an overview ScienceDirect Topics

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).
