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.
Steam boiler water treatment equipment What is the role of the boiler itself? Core Tip: boiler water treatment of new fuel gas steam and basic purpose. Well boiler water treatment is an important element to ensure the safe and economic operation of the boiler. Due to the high combustion temperature of the oil, gas. And most of the oil, gas boilers (especially imports of fuel gas-fired boiler) small size, compact structure, higher requirements for water quality, water treatment, if done well, it will cause boiler fouling, corrosion, not only a waste of fuel and easy caused by blocked pipes, burst pipes and other accidents, causing serious boiler will be scrapped biggest economic losses. Therefore, fuel oil and natural gas boilers have to do a good job of the basics of boiler flowing water boiler hot sale water treatment.
Shanxi Province to continue to improve and protect the environment, prevention of air pollution, with "Environmental Protection Law of People's Republic of China", "People's Republic of China Air Pollution Prevention Law" and other relevant laws, introduced the "Shanxi Atmospheric Pollution Prevention Act" ((hereinafter referred to as " regulations ").
"Regulation" is mentioned, Shanxi coal consumption will implement the total control system, and gradually adjust the energy structure, reduce the proportion of coal in primary energy consumption. Provincial People's Government will work with the energy department in charge of relevant departments, according to the needs of economic development, social and environmental carrying capacity of resources, the development of the region's total coal consumption control target.
First, governments at all levels to limit sulfur points, high ash coal mining. New coal mines should simultaneously supporting the construction of coal washing facilities, so that the coal sulfur content, ash content meet the required standards. Have been built in addition to the mining of coal mine belonging to low-sulfur, low-ash or coal-fired power plants have been in accordance with the requirements of discharge standards do not need washing outside, it should be a deadline for the completion of supporting coal washing facilities. When coal, gangue, coal cinder, coal ash and other materials, should take fire and dust prevention measures to prevent air pollution.
Second, the coal-fired power companies, coking, and other steel companies use coal shall clean production processes, supporting construction dust removal, desulfurization, denitrification device to reduce the generation and emission of atmospheric pollutants.
Third, the city government should promote cogeneration and district heating coal heating in the region. In the central heating pipe network coverage area, prohibit new construction, renovation, expansion scattered coal-fired heating boilers, central heating pipe network coverage prior to the completion of use of scattered coal-fired and coal-fired heating boilers have been built can not discharge standards heating boilers, should be demolished within the prescribed period the city government.
Fourth, the Municipal People's Government shall be divided into districts to improve the quality of atmospheric environment in accordance with requirements, it will be designated urban area to ban coal region, and gradually expand. County (city, district) people's government can scoping ban on coal zone in accordance with the actual situation. Delineation ban on coal zone should consider the needs of life of local residents. In addition to coal coal ban areas, central heating and raw material coal companies, prohibit the storage, distribution and burning of coal and its products.
Fifth, governments at all levels should strengthen the management of civil bulk coal. Prohibit the sale, does not meet the civil standard of quality coal for coal, lignite ban, coal washing, slime and other low-quality coal use low-quality coal as a civilian.
