easy operation 4 mw natural gas boiler

easy operation 4 mw natural gas boiler

You must know the easy operation 4 mw boiler energy problems (induced draft fan power consumption rate, steam consumption) draft fan causes problems 1.1 boiler flue dust and fouling, in particular air preheater fouling, resulting in increased resistance to smoke duct . 1.2 boiler flue, tail heating surface and dust leakage. 1.3 Leakage Rate large air preheater. 1.4 furnace excess air coefficient is too large. 1.5 unit load changes, run the adjustment is not timely, resulting in furnace pressure is too large. 1.6 unit load or low frequent starts and stops. 1.7 coal into the furnace worse, from the design value. 1.8 low efficiency filter. 1.9 draft fan blade badly worn, low operating efficiency. 1.10 fan outlet flue gas desulfurization big resistance. 1.11 soda boiler pipes for leaks. 2, 2.1 to 2.1.1 operational measures to solve the problem of the strict implementation of soot blowing system to prevent the heated area ash, blocking ash, flue gas system to reduce resistance. 2.1.2 holding the induced draft fan, the flue gas separator baffles and dampers in the fully open position. 2.1.3 The experiment showed combustion boiler, proper control of excess air in the furnace. 2.1.4 adjustment chamber negative pressure, air leakage reduction furnace and the flue. 2.2 routine maintenance and testing 2.2.1 induced draft fan performance test to determine the optimum operating point and efficient workspace. 2.2.2 boiler, air preheater, a flue, ESP and other system leakage inspection, process. 2.2.3 timely check processing chassis, shaft seal leakage. 2.3C / D repair, eliminating defects 2.3.1 down strict accordance with movement clearance adjusting fan. 2.3.2 induced draft fan blade defect action elimination hand vane opening adjustment. 2.3.3 Importers and induced draft fan baffle opening check. 2.3.4 duct tightness check process. 2.3.5 wave plate replacement air preheater, rinsed sector plate gap adjustment. 2.3.6 eliminate dust defects and improve collection efficiency. 2.3.7 clean flue gas desulfurization system, flue resistance is reduced. 2.3.8 eliminate soda boiler pipe leakage defects. 2.4A / B repair and transformation 2.4.1 Check and repair the fan blades, replace seriously damaged blades if necessary. 2.4.2 for energy saving fan efficiency below 75%. 2.4.3 The fan motor frequency transformation. 2.4.4 of the precipitator, if necessary, transform and improve collection efficiency.

Not the indoor air clean, but also to contribute their efforts to reduce the haze of it. Using electric easy operation 4 mw boilers, not only saves space, but also as a make beautiful furniture, beautiful and seductive. Electric boiler, electrical energy is directly converted into heat energy, fast heating, thermal conversion efficiency is close to 100%. With conventional heating methods is very significant energy saving effect. Electric boiler to meet intermittent heating, the temperature of the room thermostat can be detected, so that the indoor temperature gradually changes, obvious energy saving effect. Low operating costs electric boiler, electric boiler heating encourage full use of national electricity policy. Operating costs compared to other air conditioning equipment, gas and other cheaper by 20% -40%.

What chemical plant easy operation 4 mw boiler fuel operating costs low chemical plant boiler fuel with low running costs what? For the former chemical plant is run mainly by coal-fired boilers. However, with the further requirement for government departments to environmental policy, now basically it does not take a coal-fired boiler. Operating costs of coal-fired boiler is relatively low under normal circumstances, but for the destruction of the environment is too high. In this regard, leaving the gas boilers and electric boilers, like biomass boilers are not within the scope of this comparison. For comparison of the two fuels boilers, or to divide the region, some areas are suitable for gas, electric boiler is suitable for some areas. If a particular case will depend on local gas prices and electricity prices. In the present situation, there are still more cost effective gas boiler. The Government is also in line with current requirements regarding environmental policy is.

For atmospheric environmental quality issues, Harbin City, Heilongjiang Province, submitted a gratifying annual summary to the people within the city. By 2018, the number of days Hashi ambient air quality standard of 310 days, an increase of 40 days, since the implementation of our 2013 new environmental quality standards, the best of the year.

January 2019, the development of ambient air quality continues to improve. "Good weather" gratifying is the result of Harbin in straw Jinshao, such as firecrackers ban on burning the same time force. Among them, strongly promote the elimination of coal-fired boilers is a top priority. According to statistics, in 2018, out of a total of 1191 Harbin coal-fired boilers to provide strong support to reduce emissions of air pollutants.

Harbin coal-fired boiler was closed down following a major way, into the central heating (including wholesale) or clean heating pipe network replacement. According to the principle "and the appropriate and, should the electric power, the gas should be gas", the clean coal central heating pipe network coverage area, the boiler unit according to claim ownership, the priority region incorporated central heating pipe network; in concentration not covered by district heating network, in accordance with the wishes of the boiler unit property, taking clean renewable energy or alternative heating means, out of coal-fired boilers.

At the same time, various related businesses also improved stations, actively cooperate with the phase-out of coal-fired boilers.

2018 Hashi out of coal-fired boilers intensity of the strongest of the year, out of range built-up area expanded from 9 to zone outside built-up areas, out of a total of 1191 units. In District 9 built-up areas, on the basis of 10 tons of steam per hour out of coal-fired boilers to achieve "clear" on the further elimination of more than 10 tons of steam per hour to 99 coal-fired boilers; county (city) district built out of steam per hour 10 116 tons of coal-fired boiler units; elimination of financial support and utilities per hour 10 tons of steam coal-fired boilers 966 units in urban and outside built-up areas in the 9th district. "Achievements accumulated over the years, significantly reducing the use of coal, reduce emissions of pollutants." Director of Air and Noise Pollution Control at the Harbin environment bureau, Li Bin Tang said.

"In order to further solve the pollution problems of coal-fired, 2019, Harbin plans in urban areas, the county (city) built-up area basically eliminated 10 tons of steam coal-fired boilers and furnaces and tea, operating the stove, coal grain storage and drying equipment coal-fired facilities; urban built-up area basically eliminated 20 tons of steam coal-fired boilers, push 35 tons of steam coal-fired heating boilers out of the urban built-up area can not be a stable discharge standards; outside built-up areas out of 10 tons of steam can not be stable discharge standards of the following coal-fired boilers. "Li Bin Tang said.
