Improve the thermal efficiency of gas burning oil steam boiler, to reduce the scale of the heating surface regardless prevention, gas steam boiler after a long run, it will produce some more or less scale. Gas steam boiler in operation, the furnace will be a series of chemical and physical reactions, in use, will form a hard and dense scale on the heating surface, which will directly result in reduced heat transfer efficiency of the boiler; and by corrosive effects of scale, will lead to reduced water wall furnace heat absorption gas steam boilers, which reduces thermal efficiency, waste input costs. The need to clean up the scale there is little that the boiler is to make long-term stable operation down. Scale thermal conductivity of only one percent of the steel, once the heating surface fouling, so that the heat transfer will be impeded, during use in order to maintain a constant output of the boiler, it is necessary to increase the temperature of the fire side. The outlet temperature of the furnace gas steam boiler is increased during the process, so that it will lose gas steam boiler is increased, so that effective heat transfer will reduce the equipment fouling in the water wall, so it is very likely It can cause water wall tube wall temperature increases lead to burst pipes water wall. Cleaning the boiler becomes particularly important. Performing the cleaning process, you can use efficient, environmentally friendly and non-corrosive cleaning agent, so that the device will be exposed to the original metallic tube, reduced to fouling. Secondly, after ignition gas steam boiler, flue gas temperature of the furnace needed to observe changes and the main steam temperature; when the main steam pressure is on the rise, if the boiler ignition, the smoke temperature rise speed or does not rise significantly Pianman, immediately check the oil on fire the gun.
Combustion gas treatment unit and a fault, 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.
Henan oil-fired boiler Introduction Product Introduction: Henan oil-fired boiler to run than electric heating boiler economic, easy to use than gas-fired boiler. With economic development and social progress and the improvement of people's awareness of environmental protection, coal-fired boilers due to serious pollution, moving away from sight, replaced by a new environmentally friendly digital boiler, such as electric heating boiler, oil boiler, gas boiler, electric heating boiler is more expensive, gas-fired boilers need to open a gas pipeline, then, if there is no gas pipeline, and hope boiler low operating costs, only select oil-fired boiler. Boot check: 1, various instruments, whether the instrument to confirm the adequacy of fuel tank, and the inlet valve is opened. 2, confirm the soft capacity and the water tank boiler water quality meets the requirements of the main valve is opened and boiler feed water inlet valve. 3, rotation of the oil filter to remove debris. 4, drain the remaining water in the boiler, while the opening operation of the low level alarm and chain. Features: 1, inserted within a fire retardant spoiler tube, slow speed exhaust enhance heat transfer, the temperature of the flue gas discharged from a low smoke chamber, reducing heat loss and save fuel. 2, furnace by computer-aided design, each of the heating surface is optimized, compact and reasonable arrangement, small boiler area, high thermal efficiency. 3, the user can set the start, shutdown time, after setting, no special duty, easy, and effort. 4, according to the boiler pressure furnace design, furnace provided with a top opening to atmosphere, the boiler is in an unpressurised state, there is no risk of explosion. 5, the inner fire tube inserted spoiler retardant, smoke slow speed, to strengthen the heat exchanger, combustion heat is conducted to a large extent in water, the discharged flue gas temperature is low smoke chamber, reducing heat loss and save fuel. 6, the water level sensor water level real-time monitoring, to continuously monitor the water level is normal furnace. While controlling the temperature and replenishment level sensor solenoid valves, the boiler water may be continuously supplied. 7, water boiler fuel water speed, water volume, widely used in factories, hospitals, schools, etc. required a large amount of boiling water units. Shutdown procedure: 1, when it is desired to deactivate the combustion boiler to the switch in the OFF position, the oil supply is stopped, the flame is extinguished, but the fan is still operating to blow away the residual flue gas in the furnace. 2, when the blower is stopped, the operation OFF switch to turn off the power and then, after closing the steam valve, and the fuel supply valve to close the valve. 3, open the drain valve when the discharge pressure is reduced after the boiler play an open valve, to drain the water in the boiler, and the steam partial open the drain valve to drain the water in the drum segregation. Daily checks: 1, check the water level regulator function: whether the automatic water pump stops. 2. Check flame monitoring. 3, is rotated, the slide cam portion lubricating, and wiping. 4, the flushing water level gauge 1-2 times (class), according to the proper operation, so that until the rinse water level gauge. 5, sewerage 1-2 times (class).
