Steam coal fired boiler manufacturer 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.

Operation of a gas coal fired boiler manufacturer gas boiler in Henan related to maintenance, the ignition operation, fire, shutdown and some other operational measures: First, the gas boiler maintenance Henan, operating procedures should be required to carry out tests on the gas transmission main boiler protection devices, ensure that the main protection correct action. Second, the ignition process Henan gas boiler, fuel pressure, fuel temperature, steam pressure atomization, atomization steam temperature and other parameters must meet the requirements of operating procedures, good place to observe oil gun fire, fire detection return to normal, prohibit short-energize inspection signal forcibly put into the oil gun running. Single oil gun when the flow is greater than 0.65kg / s, exit the gun should be run immediately. Third, observe boiler ignition temperature rise rate of fire smoke significantly Pianman furnace flue gas temperature of the main steam temperature, steam pressure rises when the main, the case of smoke or boiler ignition temperature did not rise immediately to check the opinions of the oil gun, if No fire was found after the fuel into the furnace, emergency shutdown, re-ventilate the furnace purge Do not allow to run into the boiler ventilation oil gun. Fourth, note that starting mill to check whether the subject returns normally coals, coal mill outlet temperature of greater than 70 deg.] C line is allowed to increase the amount of coal (three grinding mill operation start of the fourth stage, the coal mill outlet line than 80 ℃ temperature allowed to increase the amount of coal, to prevent excessive vibration furnace). Full stop before the gun when the present discharge amount of coal is increased 5.0kg / s or more. 6.3.5 Operating Henan gas boiler, "furnace black", "lose the protection of the main fuel" must be put into operation as required operating procedures. In case of a fault protection device itself appears to be temporarily out of operation, to be approved by the competent manager or chief engineer before implementation. "Furnace black", "main fuel unprotected" means the period out of operation, priority monitoring attendant to furnace pressure, the oxygen, the main steam temperature, the main steam pressure and other parameters, and through the furnace of fire industrial television monitor, and if found hearth fire, emergency shutdown. Sixth, Henan gas boiler normal operation, the fuel system and oil spare gun good condition, found that boiler combustion instability immediately put oil combustion. Seven, after Henan gas boiler fire, into the oil gun is strictly prohibited without the operation of the boiler ventilation. Eight, gas boiler has confirmed the fire, when the MFT is not operating, emergency shutdown, and check that the two primary air fan, 4 mill, 16 oil gun has stopped running. Back nine, Henan gas boiler trip or normal shutdown to be purged immediately ventilate the furnace, the furnace unburnt coal dust and combustible gas pumped in a timely manner. And promptly shut down the boiler supply and return oil total gate manually to prevent leakage of fuel oil gun into the furnace. Ten, Henan gas boiler shutdown purge gun ban mill and pulverized coal into the furnace exhaust.

Jinzhou construction and installation company needs an electric heating hot water coal fired boiler manufacturer 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.

Why are gas-fired coal fired boiler manufacturer loved it public due to the nature of our resource structure, the proportion of coal resource structure had relatively large, so the gas boiler is also a time position in the market significantly. However, with the recent changes in the structure of resources, and the environment pollution situation, relying on natural gas-fired boiler advantage is gradually replacing gas-fired boiler, a new main market. gas boiler market position became clear, that has its own distinct advantages, the following comparative analysis of the advantages of gas-fired boiler. gas boiler natural gas as fuel, the fuel burning quickly, the power generated by large, so efficiency is high, compared with 50% efficiency gas boilers% higher. While natural gas prices higher than the price of coal, but in addition to fuel other than the cost, as long as the investment conduit can be. gas boiler is not the same, in addition to fuel costs, as well as transportation costs, labor costs, storage costs, the overall price is not cheap, so from a cost point of view, natural gas overall advantage. Because natural gas itself sufficient combustion and clean burning, non-polluting emissions, it is by far one of the most environmentally friendly energy up. coal combustion emissions Sulfur points, more ash, environmental pollution more serious, which is incomparable with gas-fired boilers. Gas boilers can bring greater environmental benefits to the enterprise.
