Industrial production is inseparable from boilers, emission control of atmospheric pollutants boiler air pollution control in Shanghai to expand and intensify the focus of the project. Currently, Shanghai Industrial boilers alternative clean energy has been completed, nitrogen oxides (NOx) emissions of major pollutants as a boiler, the boiler due mostly low shelf emission source of ambient air near the ground and ozone greater PM2.5 influence, therefore, this release the new standard, the boiler will be low-nitrogen transformation, improve Shanghai air quality, protect people's lives and health and other aspects demand a strong thrust of great significance. Throughout the country, Beijing, Tianjin and other places have started low-nitrogen transformation boilers for low-nitrogen transformation has a more mature technology reserves. Based on the above considerations, for the effective control of NOx emissions from boilers, to further deepen cooperative control of PM2.5 and ozone, according to the standard first, to further accelerate the transformation of governance principles, it is necessary once again to revise the standard boiler.
According to local environmental standards and revision procedures, the Municipal Environmental Protection Bureau held a meeting to hear the relevant departments, enterprises and the opinions and suggestions of experts, and in 2017 August 4 to September 15 in the online open standard full text to solicit public opinion. At the same time the Ministry of Ecology Environment solicit written opinions Municipal Development, City Commission by letter and other related commissioned Bureau, industry organizations and boilers, production units and other enterprises. Municipal Environmental Protection Bureau and the Municipal Quality and Technical Supervision on January 19, 2018 organized the expert technical review meeting, the panel agreed that standards through technical review. Approval by the Municipal Environmental Protection Bureau and the Municipal Quality and Technical Supervision audit report to the municipal government.
The new standard has been revised for several aspects, one is no longer on the "central heating boiler and the nominal amount of evaporation less than 65t / h boiler cogeneration" provisions alone time; the second is to simplify the original class standard boiler merged into " gaseous fuel boiler "and" boilers "categories; are three different degrees of contamination tightened limits particulate matter, sulfur dioxide and nitrogen oxides; four new boiler is implemented from the date of implementation of this standard, the boiler given a transition period of about two years.
New standards for gaseous fuel boiler particulate matter, sulfur dioxide and nitrogen oxides are applied strict limits, but mainly considering the control of nitrogen oxide emissions, and further improve air quality. In the transition period boiler (1 October 2020) to limit nitrogen oxide 150mg / m³; after a transitional period of 50mg / m³. Date of implementation of new boiler nitrogen oxides from standard starting execution 50mg / m³ limit. Taking into account the comprehensive utilization of straw in Shanghai, biomass fuel boilers follows the standards of the original project control and limit requirements.
Methods of operation and precautions gas steam boiler steam boiler with a gas advantage of social development is increasingly clear that the future economic level to enhance people will focus on comfort. Throughout the heating market innovation Although several decades of history in the worldwide gas boiler, but because of China's housing form, heating the environment and foreign difference is relatively large, there is currently in use gas boiler, there are still some unresolved issues The problem. Gas-fired boiler during use, the pipeline can be said is essential. Gas-fired steam boiler pipeline system is necessary to ensure normal supply of natural gas equipment, must pay attention to anti-corrosion of boiler tubes gas. Pipeline gas boiler heating system after a long period of use, will gradually varying levels of wear and degradation slowly, then the gas boiler pipeline corrosion problems which need to pay attention to it? Gas steam boiler heating pipe residual soldering flux has not been removed leaving a clean and cause corrosion in the water system, these regions are more easily aggravated rust corrosion, a long time would cause a pinhole on the heat sink, resulting in leakage. Some flux comprising an organic acid, bis more metals together form electrolytic corrosion effect. The most common heating systems made of stainless steel and iron materials with copper, galvanic corrosion occurs between the iron and copper, in which case, the corrosion rate of steel will be faster than the copper. Since the gas boiler system design, such as a bad selection pump, or the position of the obturator when the bad systems are not very good, the external negative pressure will pump air into the system, so that oxygen in the air system to accelerate corrosion of metal. Will have a good ability to maintain self-neutral water quality, but when the water quality is not good, there are a lot of home electric boiler condensing heat exchanger made of aluminum materials, aluminum is due to the appearance of easily forming a dense aluminum oxide protective film this layer of oxide film can easily be removed by acidic or basic water, resulting in occurrence of corrosion. The metal heating apparatus of the system generated during cutting, the whole or partial etching adhesive residue bonded pipe, as well as some mineral oils, residual casting sand and radiator systems of microorganisms in the system will be increased.
How pressure vertical residential oil hot water boiler the security work in Year 6 at night, is located opposite the old steam boiler certain aquaculture farm town of Rudong Ju Wang Tan explosion cause of the accident is operating a boiler operator improper. Such as shrimp farms in the South East of whitening, the use of the boiler is very extensive, mainly used for farming shrimp shed warming. Before many farms use steam boilers, higher risk, many farms put on a higher level of security pressure hot water boiler. Pressure hot water boiler is no risk, but it does not mean you can neglect of duty fireman. To regularly observe the water level to avoid low water level, the situation appears dry, otherwise there will be a certain risk, but will seriously reduce the life of the boiler using pressure hot water boiler. Boiler operator should note the following: 1, strict implementation of rules and regulations, seriously concerned to learn boiler expertise, and constantly improve the level, to ensure safe and economic operation of the boiler. 2, the pressure hot water boiler in use, organizations and individuals will be allowed to change the structure of the boiler, valves and piping system 3, before the predetermined succession visits to check a variety of devices, comprising: a water tank (hot water tank, expansion tank) , the amount of energy (boiler gas meter), a thermometer (temperature of hot water tank, the boiler water temperature of heat medium) and the like operation, when the shift operation to check the recorded inventory tool, and to learn more about the operation of the boiler. 4, take over staff as required, shift and provisions ahead of time to take over the boiler room to do the preparatory work, and to understand the operation of the boiler. 5, shift work were prepared in advance, be careful and comprehensive inspections and investigations, to keep the boiler running. 6, shift workers should take over personnel issues related to equipment operation, water quality and boiler blowdown, etc., without handing, transfer of personnel shall not leave their jobs. 7, keep the boiler running when the boiler clean, no dirt, no leakage, no rust and corrosion, carefully fill out detailed equipment maintenance records. 8, using the boiler room is one of the vital sectors of the boiler unit, in addition to the boiler room workers, leaders and security, defense, department managers, other unauthorized persons do not access inside. 9, prohibits storage of flammable boiler room and other debris and the like, loaded with a small amount of lubricant required, cleaning the oil drums, oiler, to be stored in designated locations, and pay attention to check whether the explosives combustion. 10, boiler room to be equipped with fire fighting equipment, carefully managed, it should not be moved or used for other purposes. 11, boiler room floors, walls, doors and windows keep clean. 12, competent leadership regularly, irregularly running records, sanitation inspection, identify problems and timely solutions. 13, at the stipulated time to work on time, do well shift recording, not just leave their jobs, leave something. 14, alcohol is strictly prohibited in the boiler room, drowsiness, gambling, fighting once found seriously.
