high pressure 3000 kw gas fired steam boiler
The main difference between the gas boiler and gas high pressure 3000 kw fired steam boiler What is the main difference between what gas boilers and gas steam boiler is? Nominally, a clear distinction between gas and steam boiler wherein the boiler fuel gas is different. The former use of natural gas, which uses coal. I think a lot of user concerns boiler is why they should cancel gas-fired boiler, because many people have purchased and used the gas boiler. If they switch to gas-fired boiler, it will be a huge expenditure. First, according to the current direction of development of the ecological environment of China, gas boilers will gradually be replaced by gas-fired boiler or other clean and green energy boilers, gradually withdraw from the stage of history. To say a big difference between the gas boiler and gas steam boilers, gas-fired boiler is mainly due to the elimination of environmental protection. From the fuel supply portion, only a gas boiler tube connected to the boiler; gas boiler needs coal field, coal (with or artificial), coal transportation, handling, storage and loading of coal boiler process. It will produce dust, causing serious pollution to the people's living environment. From the point of view of atmospheric emissions, natural gas is very small dust content, substantially negligible; high ash content of coal, the ash content of about 10-30%, the combustion smoke. If dust emission reduction facilities, emissions will increase; if more dust removal facilities, the corresponding costs will increase, this is not a long-term solution. In addition, the sulfur content of natural gas is very small, dust removal, desulfurization and denitrification can get gas boilers, gas boilers need only consider the denitrification problem. From the other point of view of waste disposal, natural gas substantially free of other contaminants, especially in city gas. In the case of coal, the coal field (especially small boilers mainly built in the open air) to produce coal slurry water during the rainy season, or sink into groundwater. When entering the surface water, the combustion ash conveyance of dust is generated. Of course, there are differences also in other ways. For small boilers, gas boilers are more energy efficient than gas boilers, equipment flow is simple, small footprint, low operating and maintenance costs, and so on. These are the main difference between the gas boiler and gas steam boilers, as well as the significance out of gas boiler. As can be seen, the use of gas-fired boiler is the trend of the whole society.
Internal gas-fired, gas-fired fuel management is equally important for wear to how to do? Detailed examination is the key, fuel management is equally important. We can according to operating conditions, gas-fired, time, planning and reasonable arrangements for wear of the check, when using fuels strict control of particle size into the furnace of coal and limestone particle size of bed material similar to strict customs, boiler waste to be treated before discharge. Want to reduce the impact on the water wall tube may be appropriate to adjust air pressure, air volume, can effectively reduce the wear and tear of the water wall. Maintenance shutdown time is generally in a standby or shutdown, check items include wear the furnace wall, the furnace seals are tight, leak or absence of smoke and the like. In the case of wear was found to be timely repair and welding, to ensure the normal operation of the high pressure 3000 kw fired steam boiler. Generally gas prior to combustion boiler needs to be filled in the combustion chamber fossil fuel, fossil fuel and bed material, the full integration of recycled materials in an air convection wind speed, wind strength and rigidity of the bottom of the apparatus, the inner core region of upwardly movement, the outer annular area of the reflow furnace wall along a downward extension of the coal particles in the furnace residence time, mineral particles, fly ash and flue gas contains a large number of large amounts of fly ash particles causes the waterwall tubes kept fast erosion wear, wear thin wall thickness, resulting in wear and tear.
December 20, "Shanghai Air Pollution Prevention Act," a modified version of issued and published by the Shanghai Municipal People's Congress Standing Committee, with effect from January 1, 2019 came into effect.
First, the discharge of industrial waste gas or coal-fired heat production specified operating business units of toxic and hazardous air pollutants listed in the directory of institutions, central heating and other facilities to implement pollution permits management according to law shall, pursuant to the provisions of Shanghai, to the municipal or district environment department applied for and obtained the focus of air pollutants discharge Permit (hereinafter referred to as emission permits); no discharge permit shall not discharge the focus of air pollutants.
Emissions to air pollutants shall comply with the air pollutant emission standards, compliance with the total focus of air pollutant emission control requirements. New construction, expansion, renovation project focused on emissions of atmospheric pollutants, the focus should obtain the total air pollutant emission targets in accordance with the provisions of, and environmental protection examination and approval procedures for construction projects. Need to apply for a discharge permit construction projects shall obtain emission permits before being put into production as required.
Second, easy to appear in the autumn and winter of heavy pollution weather, the city of steel, building materials, coking, casting, aluminum, chemical high emission industries related company should arrange production plan to strengthen air pollution control measures. Economic information administrative departments should strengthen the guidance jointly with the municipal environment department.
Third, the environment department to determine the emissions of air pollutants key sewage units, must be configured using air pollutant emission-line monitoring equipment, and the environment departments into a unified monitoring network.
Fourth, in addition to coal-fired power plant, the city's ban on new or expanded coal burning, heavy oil, residual oil, petroleum coke, high-polluting fuel (hereinafter referred to as high-polluting fuels) facilities; the construction of coal-fired power plant in accordance with the relevant provisions of Shanghai .
2 t 2 t introduce gas boiler gas boiler burner arranged good technical performance, the use of automatic combustion ratio adjustment, automatically adjust the water supply, the program start and stop, automatic operation and other advanced technology, and having a low water level and low level alarm, high . steam pressure, turn off automatic protection function of the boiler has a compact, safe, reliable, simple, rapid installation, low pollution, low noise, high efficiency features: 2 tons of gas high pressure 3000 kw fired steam boiler with a leading domestic level, and industry compared to the same parameters of the boiler, with a compact, power, fast boosting, high thermal efficiency. Advantages: use all wet back shell type pyrotechnic tube structure. This structure because of its compact structure, small footprint, originally applied in the marine boiler. This architecture uses three return, the oil mixed with air or gas well through the atomizing burner, complete combustion in the furnace in a corrugated, folded from the rear chamber into the first tobacco smoke return pipe to the front smoke box to the second return pipe tobacco, cigarette box, is discharged after the last to enter the chimney.
