screw pipe 3-pass furnace coal fired steam boiler

Gas-fired screw pipe 3-pass furnace coal fired steam boiler and gas steam boiler which is more energy-efficient? General business in the procurement of steam boilers were more often or consider production efficiency problem, we need to know what kind of fuel steam boilers more energy-efficient choice is clear, and that is the most common gas steam boiler and gas steam boiler comparison which is more energy efficient? Following on from me give you an analysis. Clear answer the same model as compared to steam boilers or gas steam boiler energy conservation, we can roughly be calculated next-ton per hour boiler full load of work to 150-160Kg coal according to the market value of fuel gas and gas to about 80m3 . A further additional energy means 'gas' is higher than the calorific value of 'coal' fuel value, and then under the same conditions, producing one ton of steam, of course, fast burning gas. Also a ton of water to generate a tonne of steam, in theory, as much heat energy is required, the low single coal market price, it is cheaper than burning gas. But better to burn coal gas and environmental protection in environmental protection. If a large amount of production if the proposed biomass boiler, coal processing than such low investment, but also more environmentally friendly.

Cade Shopping Mall is located in central Shanghai Hongkou District, Shanghai Daily larger flow of people in the region. The introduction of Shanghai air pollutant emission standards, boiler flue gas emissions of nitrogen oxide emissions to less than 80 mg / m, Shopping Mall a coal-fired boilers have been used for many years, NOx emissions far super to this request, the urgent need to replace more environmentally friendly low nitrogen emission boilers. Other units through the use of fast Boiler introduction and understanding, determined and fast boiler to achieve cooperation, party fast to their specific needs to recommend one condensing gas hot water boiler of a 4.2MW for heating needs of the shopping center.

Electric boiler with traditional coal boilers What are the advantages compared to? 1, environmental protection, health, the family does not appear the phenomenon of soot wander around the string, there will not be a black cinder material made everywhere. 2, and effort. L do not get up early every day fire, dig boilers, transport cinder, as long as you can plug in the power, if you want power, you can lower the temperature at night several. 3, security. In order to ensure the traditional boiler room, especially in northern areas, full, so there is often a phenomenon soot poisoning occurred at bedtime will certainly pressure of steam coal, and electric boilers do not worry about this, with leakage protection, water protection, ground fault protection, vapor overpressure protection, overcurrent protection, power protection, automatic protection boiler, antifouling functions. 4, electric boiler temperature can be provided, high precision. Want how high the temperature can be set.

Steam boiler wear and electric test pump DSY Henan fast boiler's screw pipe 3-pass furnace coal fired 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.
