combined gas fired water tube boilers in Oceania

Oil-fired combined fired water tube boilers in oceania technical analysis when equal sulfur content greater body oil and coal, low-temperature corrosion of boiler fuel in general is much more serious than a coal-fired boiler, for two main reasons: 1 coal-fired boilers, especially pulverized coal, coal 90% of the ash content of the flue gas is taken away, fumes generated in the sulfuric acid vapor is adsorbed fly ash in the flue gas, sulfuric acid vapor in the flue gas is reduced; coal combustion, about half of the sulfur remaining in the ash . While combustion of oil, the sulfur content of the fuel is almost complete conversion of SO2, the fuel ash few, little fly ash in the flue gas, the flue gas adsorption capacity of the sulfuric acid vapor is weak. 2. higher hydrogen content in the fuel, about 11% to 12%, per ton of fuel combustion can produce about one ton of water vapor, when the fuel in the flue gas water vapor partial pressure higher than when coal, lignite but because with water and more exceptions detailed in Table 1 below. When these two reasons that the fuel, the concentration of sulfuric acid vapor in the flue gas is large, when the sulfuric acid vapor in the flue gas is not only a so-called thermodynamic point of water vapor partial pressure is low is formed, as shown in Table 1. When the flue gas in a small amount of sulfuric acid vapor, the flue gas dew point of significantly increased. Effect of sulfuric acid concentration on the corrosion rate is large, typically at a sulfuric acid concentration of 40% to 50%, the fastest etching. Due to use of fuel oil-fired boiler, the flue gas dew point is not only high, but the sulfuric acid concentration in the air preheater heating surface is also formed large, low-temperature corrosion is worse than boiler fuel fired boilers.

Gas combined fired water tube boilers in oceania 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.

What is the state of a burning oil-gas combined fired water tube boilers in oceania after it is put out? How to judge whether the burning oil and gas boiler is extinguished? Oil-gas boiler manufacturer-gas-fired Fangkuai boiler for you to introduce in detail: The indicator value of the negative pressure gauge in the furnace of oil and gas fired boiler suddenly increases, the furnace blackens, the flame can not be seen from the fire hole, the combustion sound in the furnace disappears, the flame monitor sends out the fire extinguishing signal. Air temperature, air pressure drops sharply, water level drops first and then rises, etc., all of which are extinguished. Due to the auxiliary engine accident caused by the quenching, such as induced fans, blower power interruption, there is also an accident signal; if the fuel supply interruption, the boiler fuel or gas pressure is reduced to zero.

Fast combined fired water tube boilers in oceania is a research and development, production and sales of high-tech enterprises, adhering to the "do professional, responsible for cleaning boiler systems integration provider" business philosophy, creating a series of excellent quality boiler equipment, such as WNS series gas (oil) boiler, SZS series of gas (oil) boilers, electric boilers and so on; second to none in the area of ​​the National clean boiler. But we never had stalled the pace of independent research in recent years, the introduction of movable type boiler, after obtaining a favorable investment market.
