normal pressure coal fired boiler

normal pressure coal fired boiler

How to pick the price of the normal pressure coal fired boiler heating boiler? 1, the first choice for the required heating area, probably determine the tonnage. Tonnage is too small will cause the price of the boiler heating can not meet the demand, the tonnage might cause the boiler to increase economic costs, reduce the thermal efficiency of the boiler. General on housing construction in northern concerned, one ton of heating boilers 6000 level, but also by the housing structure and the heating temperature. 2, determining the pressure heating boiler temperature. Pressure and temperature are the basic parameters of the boiler, to determine these points to your boiler is more clear. 3, to determine the material heating boiler. Today, coal-fired boilers have received a lot of national policy restrictions, you need to know your local ban on coal policy. If you are not good enough coal-fired boiler, you can consider natural gas, biogas, biomass fuels, such as methanol, which are a popular choice for customers.

Gas normal pressure coal fired boiler energy-saving programs: from "under the dome" to "Battle of the sky", efforts to promote China's environmental protection policies become more stringent, "coal to gas", "coal to electricity" and other energy-saving boiler has also become a hot item. Industrial coal-fired boilers, coal-fired boilers civilian or eliminated, or demolition transformed into energy saving gas boiler.

Jinzhou construction and installation company needs an electric heating hot water normal pressure coal fired boiler house construction, after screening and comparison of various brand boiler industry, our excellent results in the cleaning of the boiler industry has been attracted to each other, in mid-2016, the Jinzhou construction and installation the company I signed with an electric heating pressure hot water boiler.

Steam normal pressure coal fired boiler wear and electric test pump DSY Henan fast boiler's 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. 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!
