Dry: six gas-fired boiler safety procedures (hot water + steam) stage, the purchase of gas-fired boiler more and more users, in many industries, such as oil exploration, hospital disinfection, chemical production, wine feed, and so on. But many users initial contact with a gas boiler told us how to get started quickly boiler operation is not clear. First, all personnel must be familiar with the operation of the boiler boiler performance and safety knowledge, certificates; this non-job employees Never operate. Duty personnel should strictly follow the regulations, do a good job operating records and shift recording, the security situation should shift equipment and run tests, carried out. When the shift to check the boiler is intact. Second, purchasing, installing, or before the initial operation of the boiler, the boiler and safety accessories must conduct a comprehensive inspection, inspection and determined within the validity period to start. Third, Kai furnace ready to check the gas pressure is within the normal range of values, not too high or too low; check whether normal pump Sheung Shui, if unusual you need to open the purge valve until the Sheung Shui so far. Open the door of each section Water Supply System (including Sheung Shui before and after the festival gates pumps and boilers); check the water level, the water level should be in the normal position, the water level gauge, a water color need to plug in the open position, to prevent false water level, if missing water can be manually Sheung; check valves on the pressure pipe, must be opened, the wind deflector must all flue opening; each knob inspection control cabinet are in their normal position; 1t h steam boiler check valve is in the normally closed state, heat water boiler circulating pump outlet valve should be turned off; check water softening equipment is operating correctly, soft indicators of compliance with national standards. Fourth, Kai furnace run time 1, steam boilers Open the power to start the burner; check manholes, hand holes around the flange and valve leaks will be tightened, if there is still leakage after tightening occurs, you need to immediately stop maintenance furnace; l when the air pressure 0.05 ~ 0.1MPa, replenishment, sewage, water supply systems and sewage screening test device while flushing water table; when the pressure was raised to 0.1 ~ 0.15MPa, rinsed trap gauge; pressure was raised to 0.3 MPa, the "fire load / small fire" knob to "fire" to strengthen the combustion; 2/3 when the air pressure was raised to the operating pressure, start warming air supply tube, slowly open the main steam valve, to avoid water hammer; out when the drain valve when steam is completely close it; after all drain valve closed, slowly open the main valve to open, and then half a turn; "burner control" knob to "Auto"; level adjustment: adjusting the water level (according to the load manually when to start and stop the pump), low load level should be slightly higher than the normal level, high load level should be slightly lower than the normal level; steam pressure adjustment: adjusting the combustion load in accordance with (manual adjustment fire / small fire) determines combustion conditions The flame color, smoke color determination condition atomisation air quantity and exhaust gas temperature observed concentration chimney, the best change in the combustion temperature to be adjusted according to the combustion. 2, start the circulation pump hot water boiler; startup burner; 15 minutes after start, "" fire load / small fire "spin-bit color button to" fire ";." Burner control "knob to" Auto "five, normal stop 1 furnace, hot water boilers' fire load / small fire "knob to" small fire "; off the burner; close the fuel supply valve; closing dampers; boiler after the temperature dropped to 50 ℃, the pump outlet valve closing cycle ; .2 circulation pump is stopped, the position of the steam boiler "fire load / small fire"; Close combustor; steam pressure drop when the sewage to 0.05-0.1MPA; closing the main steam valve; manual replenishment to the higher level; Close valve; Close supply valve combustion; closed dampers; six off the main power, an emergency shutdown, the steam boiler main steam valve closed; off the main power; 2, boiler water boiler inlet and outlet valve closed; opening the emergency valve and the emergency discharge replenishment valve; off the main power switch; notification superiors.
Gas boiler Burner Failures and gas boiler burners Failures and - best ￼ a gas boiler, gas boiler burner ignition misfire rod reasons: 1, the ignition bar gap interposed carbon residue with oil. 2, ignition rods fragmentation. moist. Leakage. 3, the distance between the ignition does not stick, too long or short. 4, ignition rods Insulation damage, short to ground. 5, ignition cable and transformer failure: cable, connector damage caused by a short circuit during ignition; transformer break or other fault occurs. Measures following five: Clear, renewal, adjust the distance, change and switching transformer. Second, gas boiler, but spark ignition rods misfire reasons: 1, the cyclone disc space ventilation is blocked carbon, poor ventilation. 2, dirty oil nozzle clogging or wear. 3, the throttle angle is set too small. 4, the firing bar from the leading edge from the oil nozzle tip inappropriate (too protruding or retracted) 5, the first solenoid valve is an oil debris blocking gun (gun small kerosene). 6, oily or too viscous to flow easily clogged or the oil filtration system the valve is not opened, so that insufficient suction pump, oil pressure. 7, the filter pump itself blocked. 8, the oil more water (boiling abnormal noise within the heater). Measures are: Clear; first wash, such as not renewed; turndown test; adjusting the distance (in 3 ~ 4mm as well); Remove cleaning (cleaning the parts diesel); Check tubing and oil filters, insulation equipment ; remove peripheral screw pump, carefully remove the cover inside out oil network, with immersion oil; renewal of the test oil. Third, when the gas boiler and turn the fire a small fire normal, off, or flashing instability reasons: 1, the air volume damper setting fire too. 2, oil fires micro switch valve (damper outermost that group) inappropriate setting (set throttle air flow rate is greater than the fire). 3, oleaginous easy to spray viscosity is too high (heavy). 4, and the nozzle plate spacing cyclone inappropriate. 5, fire nozzle worn or dirty. 6, the preliminary fuel tank temperature is too high, so that the steam not smooth oil pump oil feed. 7, fuel oil boiler water. Action: Test gradually reduced; heating temperature; adjusting the distance (between 0 ~ 10mm); clean or replace; approximately set to about 50 deg.] C; or drain oil change. Fourth, the noise increases gas boiler burner reasons: 1, cut-off valve is closed or the passage into the fuel shortage, an oil filter blockage. 2, the oil inlet temperature is low, the oil viscosity is too high or the temperature is too high the pump inlet. 3, oil pump failure. 4, fan motor bearing damage. 5, dirty fan impeller. Processing methods: ① the oil line check valve is open, if the oil filter is working properly, the filter cleaning pump itself. ② heating oil or reduce the oil temperature. ③ Replace the oil pump. ④ replace motor or bearings. ⑤ cleaning fan wheel.
ASME is referred to as "the American Society of Mechanical Engineers", mainly dedicated to the development of machinery industry standards, and was recognized by most countries in the world. Get ASME certification is fast boiler and pressure vessel products to the international market, the only way to obtain a certificate issued by ASME and stamp means getting the products exported to international market, "pass."
The advantages of gas 1t h steam boiler which is now very popular gas steam boilers, and many other types of boilers are selected by the user to be the transformation of gas boilers gas boilers, the advantages of gas steam boiler, what does? Today small breakdown of the gas for you What are the advantages of a steam boiler. First, let's take a look at the fuel gas fuel with respect to what other advantages: 1, good combustion process using readily mixed with air, exhaust loss of small, high-efficiency boiler; parts of sulfur and low ash fuel, heating surface coking does not occur and high temperature corrosion phenomena; high gas velocity, small overall size boilers, low boilers metal consumption; 2, adjust the properties of flexible gas heating value is easy to adjust, both fuels blending can be used; the same is applicable to multi-boiler such fuel; has a strong ability to adapt to changes in the heat load, the combustion easily achieved adjustment; 3, environmental pollution not directly broken, quieter operation case; ash and sulfur content is much lower than that of coal and oil fuel; when the burned gas is not ash generated when a large amount of gas to be treated; small contamination of soil; low dust content in the flue gas, a small air pollution; oxynitride main pollutants produced during combustion; 4, main pipeline transportation easy transport, no transport vehicle during Feisa, noise pollution; use, no gas as required before crushing. These are the advantages of gas fuel, in fact, the advantages of gas fuel can also be seen as the advantages of gas steam boiler. Here, the advantages of gas steam boiler, what does the first, gas boiler ash pile is not required to save the land;? Second, saving water boiler auxiliary production. Gas boilers and gas water boiler is equal to the normal production, but saves the auxiliary gas boiler for water gas boiler dust, slag and other dust, while not need to configure an accessory device and a fuel drying apparatus slag or the like can be greatly reduced boiler the investment costs; third, reduce staff, saving labor costs. Gas boiler auxiliary boiler equipment less than gas, fewer staffing requirements, the burden of wages and benefits would cost much less. While reducing labor intensity, gas boilers in coal transport, slag process requires high physical strength, and gas-fired boilers staff labor intensity is small; fourth, saving the cost of production of electricity boiler. Less gas boiler fuel delivery and other auxiliary equipment, low-power, continuous running time is short, so low power consumption, compared with the cost of the province; fifth, gas boiler room layout flexibility, small footprint, low noise generated; sixth, Improve the environment. Generate a lot of smoke gas boiler is running, causing great pollution cleaner, gas boiler environmental protection of the environment, due to the ash content of the gas, sulfur and nitrogen volume is lower than the content of the coal, flue gas dust generated by combustion minimal, flue gas emissions is easier to reach national standards required for combustion equipment, can greatly reduce the pollution of the environment.Free Chat
