2. szs series oil/gas boiler

The SZS is a modern D-type water tube boiler design, with gas tight membrane wall construction for all furnace walls including the front wall to maximize heat transfer. Tube manipulations for burner and man door penetration maintains optimum circulation. Two stage separation within the steam drum ensures high quality steam.

When we use the boiler, it is unavoidable to have faults or abnormal phenomena, but in order not to affect the normal use, when the boiler appears problems should be dealt with in a timely manner, then in the face of all kinds of circumstances, how should we deal with it? Share with you some ways to handle exceptions. If only the boiler circulating pump abnormal, such as its current reduced, outlet pump pressure return to zero, which means that the pump is idling non-oil, may be caused by vaporization of oil. Therefore, first of all, Yang should take measures to identify the cause of vaporization; if the filter blockage causes the circulating pump to empty, the by-pass cleaning filter should be opened immediately; such as the new heat transfer fluid containing water or Water-decomposing gas is not excluded in the system, then the open valve should be opened immediately. If the circulating pump pressure is constant, the current increases and the flow rate decreases, the heat transfer fluid is metamorphic and the viscosity is increased, so it should be replaced or regenerated in time. If the gas containing water or decomposing is not excluded from the system due to the new heat conduction fluid, the gas should be discharged immediately by opening the valve. When the current of the circulating pump is lower than the normal value, it shows that the efficiency of the circulating pump is lower and the flow rate is decreased, which may be the fouling blockage of the heating pipeline, and the stainless steel chain should be cleaned. If the pressure difference between the front and back of the filter in the boiler increases and the pressure of the pump inlet drops, the filter may be blocked. The bypass should be opened and the filter should be turned on. Remove cleaning. In addition, the low outlet temperature of the liquid-phase heat carrier furnace and the lack of heat supply are mainly due to the problem of ash accumulation, so soot-blowing should be carried out in time. A more common problem with the boiler's grate is that it is stuck because it is broken or loose after the pin has fallen off; metal inclusions in the coal trap the grate; the grate is arched; and the tip of the slag stopper sinks to jam the grate. In view of this phenomenon, it is necessary to clean up the debris with the plate hand-down converter row, replace the broken furnace platoon and start again, if it is stuck again after the start-up, then check the causes after stopping the rotation and solve the problem in detail. At the same time, it is necessary to adjust the screws on both sides and tighten the grate, if it is still not correct. Often, you need to change the sprocket.

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.

We learned that recently, the city of Wuwei in Tianzhu county government announced that it will carry out a comprehensive coal-fired boiler demolition "clear" action aimed at remediation efforts to increase coal-fired boilers, and resolutely fight pollution control tough fight, complete coal-fired boilers out of the grid, clean energy transformation of the task of governance and compliance. The task of governance staff, shimenzhen government, Hua Temple town government organization done by the Bureau of Wuwei City, the ecological environment will Tianzhu Branch, and Hua Temple shimenzhen government and town homes for the elderly failed fork Station coal-fired boilers were concentrated tear down. To continue to improve the air quality of the environment, protect the health of the people made great contributions.

Tianzhu County will further promote the comprehensive improvement of coal-fired boilers, and through the elimination of the demolition, clean energy transformation, environmental compliance management, etc., with the completion of the internal area of ​​coal-fired boiler remediation tasks, achieve discharge standards in all coal-fired boilers. Meanwhile, the industrial park central heating, phasing out central heating, and for 10 tons of steam coal-fired boilers in the gas pipeline network coverage.

Up to now, Tianzhu County by incorporating central heating, clean energy transformation, compliance management, has completed the renovation of 74 coal-fired boilers. The remaining four coal-fired boilers in Tianzhu Force has developed a program of clean energy for heating reconstruction project, planned in June renovation, completed in August.
