Recently, Zhongshan City, Guangdong Province, the ecological environment expanded Bureau held a working high-pollution fuel combustion zone ban will promote further urge the major companies on time and quality completion of p and i stand by in boiler rectification task. It will be mentioned in the need to deeply Publicizing the newly revised "Air Pollution Prevention Regulations of Guangdong Province" and "boiler air pollutant emission standards" and to implement the next phase of work to expand the scope of the ban on burning zone, Zhongshan City.
District policy is to implement the ban on burning blue sky, Zhongshan City, to win the Battle of the most important, relevant departments, district towns, enterprises should pay full attention and positive action in order to "limit Forced, territorial responsibility, multi-pronged approach , coordinated implementation of the "principle, should work together to create synergy, take the following measures to ensure that all targets are met within the deadline.
According to published Zhongshan City, "about expanding the scope of high-pollution fuel combustion zone ban notice" requirement, in addition to coal-fired cogeneration thermal power plant units have been built high-pollution fuel industrial equipment must be removed or completed by June 30 this year clean energy transformation, all enterprises should actively cooperate with government departments to complete the rectification task on time and quality.
According to requirements "Boiler Air Pollutants Emission Standards" (DB44 / 765-2019), and from April 1 this year, the province's start step by step implementation of the new air pollutant emission standards boiler, new boiler effective from April 1 this year, in accordance with the different regions in which, since 1 July 2019 or 1 July 2020 to implement the new standard boilers. Compared with the original standards, new standards particulate matter, sulfur dioxide, nitrogen oxides and other pollutants received strict emission limits help to further reduce the total emissions of air pollutants.
Hazard Ultra-low-load operation of the p and i stand by in boiler What? Coal-fired boilers is 70% to 100% of rated load, fuel gas boiler 60% to 100% of rated load. Ultra-low-load operation is deemed to run below this range. Then the ultra-low-load operation of the boiler harm What? Fuel gas-fired boiler factory and you came to talk about it! 1. difficult to guarantee the quality of steam: with the boiler load decreases, the steam temperature and humidity will be affected, in particular for a boiler with a superheater, boiler load is reduced, resulting in reduced exit steam temperature is difficult to maintain rated steam temperature, steam quality deterioration. When the superheated steam temperature drops below nominal, soda heating surface system conditions will enter the danger zone, when the load is low zui called technically permissible load. 2. boiler water circulation decreased reliability: fuel gas circulation usually natural circulation. Ultra-low-load operation, because a small amount of fuel into the boiler, the temperature drop across the furnace, the heated water wall weakening, boiler water circulation flow rate will be reduced, reliability is lowered circulation. 3. The rear of the boiler heating surface acid corrosion aggravated: Ultra load operation, the furnace temperature was decreased to varying degrees departments, the exhaust gas temperature will be reduced. It is easy to make the heating surface of the metal wall of cryogenic temperature below the temperature of the vapor *** sulfuric acid, sulfuric acid vapor condensation heating surface will be at a low temperature, resulting in low corrosion of heating surfaces. In summary, fuel gas-fired boiler ultra-low-load operation this issue, we can not be ignored.
How the production of industrial gas steam p and i stand by in boilers choose? Gas-fired steam boilers for industrial production supporting the most widely used steam supply devices, and how to choose the industrial gas steam boiler is directly related to production efficiency and profitability, generally can be considered from product configuration, operation, safety, etc., in order to select the most suitable steam boiler. 1, Performance: the thermal efficiency of a steam boiler includes the exhaust gas temperature and the like, thermal efficiency as high as possible, the exhaust gas temperature is as low as possible. 2, Configuration: how to choose the industrial gas steam boiler, not just a body we want to choose the boiler, as well as soft water equipment, safety valves, sub-cylinder and other accessories. 3, price: should include the cost of steam boilers, boiler accessories and operating costs. 4, security: security is an important factor we need to consider, because safety is the fundamental premise and production. 5, energy: energy saving relationship with our use of cost, but also on the environmental issues of society. 6, the operation: Some boiler control are complex and difficult to put into use, along with it will affect productivity. 7, Service: the event of failure will affect production, even unimaginable destructive appearance, so choose a good after-sales service manufacturers. 8, speed: the speed of start-up speed will also directly affect our production, steam boilers generally are not open every day, if the start time is too long not only a waste of fuel, but also a waste of productive time. 9, brand: a good brand is accumulated by the user reputation, we want to choose the strength of some, but not blindly choose to go to some foreign brands, because these are the basic agent, the problem often is hard to find in the event of service center. One steam boiler user achievements of today's Nuobei Si brand, adhere to customer first, the customer and security interests first, to help solve the problems of how to produce steam supply for industrial gas steam boilers.
Guangxi textile mill steam p and i stand by in boiler how much the price in Guangxi region still has a lot of textile mills, textile mills for the process of reproduction in the process is the need to use a lot of steam, which is a large textile mill demand for steam boilers of the reasons . For textile enterprises, it must be for the actual situation of their own understanding of the plant. In this case, to facilitate and to communicate with the boiler manufacturers inquiry. Recently, a Guangxi enterprises to fast boiler consultation, they have to purchase a mill for the production of a steam boiler, for businesses, but for their actual production is the ability to understand, but for their own needs price tonnage there is the procurement of boilers are want to know. After detailed accounting technician fast boiler and concluded that textile mill in Guangxi steam boiler 1 Taiwan 4 tons is possible. At present, the model price is about 500,000. So for the price of boiler steam mills in Guangxi have detailed understanding.
