6 tons gas steam boiler steam pressure adjusting a boiler operation, must frequently monitor the pressure gauge indicated. To maintain stable steam pressure, boiler pressure must not exceed the design pressure. Second, increasing boiler load: Steam pressure decreased boiler load is increased, if the level is high at this time, the amount of water should be reduced to a water supply or suspend, the amount of coal and increase the air volume. Gradually increase the amount of water at the same time to strengthen the burning, keep the steam pressure and the water level is normal. Third, the boiler load reduction: the vapor pressure rises to reduce boiler load, if the level is high at this time, the amount of coal should be reduced and the air volume, reduced combustion. Then the appropriate water reduction or suspension of water supply to the water vapor pressure and stability in the nominal range. Then press the normal combustion and the amount of feed water 8 to adjust. If the actual water level within the boiler is low, to increase the amount of water should, until the water level returns to normal after the combustion and needs to be adjusted according to the water vapor pressure and load changes.

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.

How to combine gas steam boiler when a parallel gas steam boiler / steam boiler two or more than two runs, the new operational boiler steam supplied to the total charge of steam, the furnace is called parallel, how a natural gas steam boiler is operating analysis of: (1) steam boiler gas before the merger, should decrease the fire. Gas-fired steam boiler burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reducing the total cost of the user is provided drain pipe, the water shall be discharged, and then washing water level gauge, the normal water level is maintained below the water line. (2) At this time, the steam pressure gas steam boiler is reduced, when the steam pressure is below the vapor piping system pressure of about 0.05MPa, the water level can be in communication with the furnace. Biomass boiler categories: biomass boilers Horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass china hot water boiler manufacturer, biomass oil furnace. (3) a combination of steam gas boiler, a main steam valve should be opened slowly. When the main steam pipe soda no impact should open the main steam valve, to observe changes in water level. (4) Complex fire, pay attention to the steam boiler water, maintain the normal operation. Gas-fired steam boiler burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reducing user fees gas steam boiler drum double lateral structure, completely overcome the bulging phenomenon boiler superheater tubes are directly exposed to the furnace caused by the heating surface is disposed more reasonable. Using membrane wall structure on both sides of the furnace, both to ensure the sealing of the furnace, but also improves the thermal efficiency of the boiler.

At the end of 2018, Yantai City, Shandong Provincial People's Government Office issued the "Yantai Blue Sky win the Battle of three-year action plan implementation details," "rules" that: in principle, to new natural gas cogeneration and gas chemical projects. Details are as follows.

Continued implementation of the total coal consumption control, by 2020, the city's total coal consumption control in less than 24.19 million tons. Developed and implemented 2018-- 2020 coal consumption reduction alternatives work, the coal consumption Yajian task decomposition implemented in urban counties. Strict control of new coal project approval, approval, filing, encourage natural gas, electricity and other clean energy alternative to coal consumption. Censorship perfect substitute for coal, improve coal reduction coefficient replace coal utilization efficiency low industry. All new, revision, and expansion projects are implemented coal coal reduction alternatives, strict implementation of alternative sources and alternative proportions.

The development of special programs, out of shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance, the following priority out of 300,000 kilowatts to run at least 20 years of pure condensing unit, run over 25 years and Condensate Pumping Units still can not reach ultra-low emission standards for coal-fired units. For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade or replacement, can co-ordinate arrangements for building the capacity of ultra-low emission coal-fired units.

Accelerate the phase-out of coal-fired facilities tea furnace built in the urban counties of the region, operating a stove, grain storage and drying equipment. The city's ban on new 35 steam tons / hour and coal-fired boilers. 65 steam tons / hour or more coal-fired boilers on the basis of complete transformation of the ultra-low emissions, with the transformation of the conditions to complete all energy saving. Out of coal-fired boilers heating pipe network coverage range. In the area where no cogeneration district heating conditions, a plurality of existing coal-fired boilers, and the like in accordance with the principle of building a large-capacity volume replacement coal-fired boilers.

The implementation of non-fossil energy doubling action plan, by 2020, non-fossil fuels in energy consumption should reach its goal provincial requirements, the city's wind power, solar power, biomass power, pumped storage power generation, nuclear power and other new energy and renewable energy power generation capacity reach 7.05 million kilowatts. Where the conditions of availability of resources, to encourage the development of biomass cogeneration county, increase renewable energy consumptive, improve social proportion of the total electricity consumption of renewable energy generation.
