If within the natural gas boiler wear how to do? Off If there is detailed examination within the natural gas boiler wear how to do? Detailed examination is the key, fuel management is equally important. According to health and time natural gas boiler, we can plan a reasonable wear health check. When using the fuel, we strictly control the particle size of coal and limestone. Should strictly control the size of the bed material. Boiler waste should be handled. Boiler slag to be treated before discharge. Natural gas boiler should be installed in the heat of use, ease of installation. Hot water pipes should not be too long. It should have a good insulating layer. Hot water output to the end of the pipe should be suitably inclined. A water supply source should be equipped with a control valve. Of emissions, natural gas boiler chimney should extend to the outside, the outlet should be higher than the boiler 1.5 to 2M. If you want to reduce the impact on water wall tube, air pressure and air volume can be adjusted appropriately, effectively reduce the wear and tear of the water wall. Check the standby time is generally down or stop. To check items include leak wear, sealing the furnace and the furnace wall of smoke. In the event of wear, the need for timely repair and welding, to ensure the normal operation of the manufacturer steam boiler coal boilers supplier. In general, before the gas-fired combustion of fossil fuels need to be filled in the combustion chamber, fossil fuel and bed material and recyclable materials in air speed, strength and stiffness of the shed fully integrated. Wind bottom means upwardly within the core region. Movement of the outer annular region of downwardly along the walls of the flow of boiler water, thereby prolonging the residence time of the coal particles in the furnace. Mineral particles, large amounts of ash and flue gas contains large amounts of fly ash particles, which continue to cause rapid wear of the water wall tube, wall thickness wear thin, resulting in wear and tear.
Steam boiler wear and electric test pump DSY Henan fast boiler's manufacturer steam boiler coal boilers supplier 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.

To enhance the thermal efficiency gas boilers What environmental policy: the combustion efficiency of combustion represents the degree of complete combustion. To improve the combustion efficiency of gas boilers and environmental protection, we must try to adjust the combustion conditions and better organization of the furnace, fuel combustion, reducing q3 and q4. Gas boiler environmental protection reduce exhaust gas temperature: at present China's industrial boiler flue gas temperature is high, is one of the main reasons of the low gas boiler thermal efficiency and environmental protection. Each small boiler flue gas temperature decreased 15-20 ° C, 15 ° C decreased every large boiler, a 1% increase in the thermal efficiency of the boiler gas. Accordingly, to try to reduce exhaust gas temperature flue gas heat recovery, reducing heat losses q2, the fuel savings. Softened water supply and condensate recovery: boiler feed water softening treatment and condensate recovery measures is to improve the thermal efficiency of the boiler. Raw water contains various impurities and fouling material, if not the water treatment boiler fouling. Low thermal conductivity of the scale, so that once the heating surface fouling due to increased thermal resistance, gas boiler output decreased to increase coal consumption, reducing the thermal efficiency of the boiler. Boiler keeps running at rated load: When natural gas boiler overload, due to the amount of fuel to be increased, the coal seam thickened, grate speed, air volume must be increased to meet the increased load required. Thick coal seam and grate faster incomplete combustion of the solid increase in losses due to increased air volume, the short residence time in the furnace flue gas, some burning of combustible gas has not finished on the drain with the flue gas, so incomplete combustion gas heat loss is increased. Meanwhile, when the overload operation, since the furnace temperature is increased thickening seam, exhaust gas temperature increase accordingly, so that heat loss is increased. Boiler low load operation, the amount of reducing gas, the furnace temperature is lowered, deterioration of the combustion conditions, incomplete combustion loss q3, q4 is also increased. When the boiler load is only 50%, due to a significant reduction in temperature in the furnace, it is difficult to maintain stable combustion furnace. Low load operation relatively increased heat loss, the overload or low-load operation the boiler will result in reduced thermal efficiency of the boiler. Strengthen the insulation, sealing, anti-leakage, anti-risk: Due to the wall gas boiler, soda temperature heat pipe system is better than the boiler room air temperature is high, so that part of the heat pipe system and soda furnace wall to radiation and convection to the loss of ambient air, heat radiation loss becomes the boiler. Only the furnace heat of the heat loss, reduces the temperature of the furnace at the same time, it affects the combustion. Therefore, the use of advanced insulation materials to strengthen the walls and heat insulation boiler pipes, reducing heat loss and improve the thermal efficiency of gas boilers and environmental protection.
