Three matters needing attention in daily maintenance of condensing 6mw fired water tube boiler in hotel

The invention and use of boilers have a long history, and the use of condensing boilers, to a certain extent, makes full use of the heat of flue gas and water vapor itself, which is a more environmentally friendly way. And all-in-one condensing boiler price is fair. However, in the process of operation, maintenance is needed to ensure the stability of the operation. The following three aspects should be paid attention to in the daily maintenance of the condensing boiler.

1, attention should be paid to the maintenance of boilers as required to a large extent in order to check and detect the existence of problems in condensing boilers in order to be able to solve or prevent problems in a timely manner, and this will also avoid further expansion of the problems. It protects the furnace from further damage and should be careful not to add antifreeze in the water. All premixed aluminum condensing boiler manufacturers introduce that if the newly installed condensing boiler system should be thoroughly flushed, the remaining oil paper or metal debris and other impurities in the boiler should be removed.

2, pay attention to the fact that this step of installing filters is indispensable and can largely prevent the boiler from being damaged. Some preparations should be made before the condensing boiler is opened for official operation. Water circulation, for example, should take up to two hours so that impurities can be removed first. Condensing boiler manufacturers also remind after the end of operation, should be timely to open the safety valve, further removal of impurities inside.

3. Pay attention to cleaning work before installation. Before installation, special additives are also needed to clean all pipes. And condensing boiler manufacturers emphasize that cleaning agents must be neutral and absolutely not to have any acidity or alkalinity in order to avoid corrosion to the equipment. In short, it should be done according to the requirements of the manufacturer. Because the materials of ordinary condensing boilers are silicon-aluminum alloy, so they are very sensitive to alkaline substances, so the ph value of hot water in the boiler should never be controlled within the prescribed range of mixed additives must be prescribed by the manufacturer. You can't use other types at will.

SZS series gas-fired superheated steam 6mw fired water tube boiler in hotel project for heating industryXinzheng Heli Thermal Co., Ltd. is a company specializing in heat energy production and central heating supplying, providing heat source for winter heating for people in Xinzheng . Facing the increasingly serious environmental problems, Xinzheng Heli decided to respond positively to the "coal to gas" policy, using clean energy natural gas as boiler fuel and introducing high efficient gas-fired boilers to replace the original coal-fired boilers. For this, Xinzheng Heli Thermal carried out an open bidding. After competitive bidding and strict selection,ZOZEN defeated other competitors and won the bid with its comprehensive corporate strength. The winning bid was ZOZEN energy saving and environmental protection product - SZS series condensing gas-fired superheated steam boiler (3 sets of SZS75-1.6-Q). The furnace and the front and rear walls of this series of boilers adopt membrane water wall structure, and the airtightness is good. The large furnace design is combined with an advanced ultra-low NOx burner to ensure sufficient fuel combustion, controlling the NOx emissions below 30mg/m³ and the thermal efficiency up to 98%. At the same time, the boilers adopted the flue gas recirculation technology and were equipped with economizers and condensers at the tail of the boiler flue, which not only followed the concept of energy conservation and environmental protection, but also met the thermal energy requirements required by the project.

Combustion gas treatment unit and a fault, gas 6mw fired water tube boiler in hotel 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.

To continue to improve ambient air quality, to meet the people's growing need for beautiful ecological environment, Zaozhuang City, Shandong Province issued the latest "blue sky Zaozhuang City win the Battle of the operational plan (2018-2020 years)" (the "Program"). "Plan" put forward, built-up urban areas to carry out experimental work, to carry out large-scale coal-fired units off white wet flue gas treatment. The main objective of the "program" is that after three years of efforts, the total emissions of major air pollutants significantly reduce greenhouse gas emissions reduction synergies, significantly reduced the concentration of PM2.5, significantly reduced the number of days of heavy pollution, ambient air quality improved significantly, the people of the blue sky well-being significantly enhanced. By 2020, the city of sulfur dioxide, nitrogen oxide emissions are lower than 27% in 2015, the ozone concentration significantly increasing trend containment; of PM2.5, PM10年平均浓度分别控制在 57 mg / m, 91 [mu] g / m or less, sulfur dioxide, nitrogen oxides average concentration continued to improve air quality not less than 62%, more than the number of days of severe contamination and declining.
