Industrial production is inseparable from steam industry boilers economics, 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.
Boiler what brand of good? Boiler what brand of good? For food plant, the steam industry boilers economic must be purchase before the choice of the boiler detailed understanding of the brand. There can be various manufacturers to compare the product after understanding. The best words for businesses to various manufacturers to conduct field investigation. Because different manufacturers focus on product boiler is not the same. Generally applicable to heating hot water boilers. If the district heating system is recommended to achieve a large-capacity hot water boiler central heating. If more accurate temperature of superheated steam, such as boiler for power generation, the adjustment should be used to cool the superheater steam boiler apparatus. Requirements for steam temperature is not very accurate. Alternatively no superheater steam boiler superheater, i.e. saturated steam boiler is preferred.
D type water tube boilers are designed with a large steam drum at the top, vertically connected to a smaller water drum (or “mud drum”) at the bottom, via multiple steam-generating tubes which carry feed water (providing the main heat transfer surfaces for the production of steam). These are surrounded by walls made up of larger water-filled tubes, which make up the furnace.
Boiler fuel oil atomization factors and industry Fuel type: this kind of steam industry boilers economic oil-fired boiler, which is one of the Website, so their knowledge and understanding, at least, to achieve the full extent of this job, thus, in order to ensure that the learning effect, therefore, to let everyone compliance as soon as possible, Next, through a number of specific issues, to initiate and conduct, so that everyone can benefit from it. 1. oil-fired boiler system, which basic components and important equipment and devices have? This oil-fired boiler A boiler, which system, the base member thereof, with a boiler and a burner both. As for its important equipment and devices, there is a feed water pump, oil pump, fuel tank, control box and five water treatment, is very important, therefore, indispensable. 2. The oil-fired boiler furnace pressure, if not clear, if you can contact the manufacturer? Oil-fired boiler, furnace pressure boiler which, if not clear, then, can consult its manufacturer, in order to make yourself clear. So, on this issue, which is to be the answer. In addition, we also need to know that, according to their different specifications, its corresponding chamber pressure, is not the same.
