On October 23, I learned from the Quanzhou Municipal Information Technology Bureau that in order to effectively promote energy conservation and emission reduction and accelerate the development of the LED industry, the city issued the “Implementation Opinions on the Promotion and Application of LED Lighting Products in Quanzhou†(hereinafter referred to as the “Opinionsâ€). It is required that by the end of 2015, the city will basically realize the widespread use of LED lighting products in the public lighting field.
Energy-saving target lighting energy saving more than half of the central urban street lights are fully upgraded! More than 6,200 street lights on 28 municipal roads can be replaced with LEDs before the end of this year.
This is just the beginning of the promotion of LED in the public lighting field in Quanzhou. According to the "Opinions", Quanzhou took the lead in promoting the application of LED lighting products in the public lighting engineering fields such as roads and administrative institutions, state-owned enterprises and institutions, and other state-owned capital investment projects. Among them, the newly-built lighting projects use LED lighting products, which have been built and used. LED products, strive to basically complete the renovation before the end of 2015; at the same time, encourage the commercial public lighting field to promote the application of LED lighting products, and strive to achieve the general use of LED lighting products in the public lighting field by the end of 2015, and achieve the same year-on-year Lighting energy saving (electricity) 50 or more.
In addition, Quanzhou also specifically requested Anxi County as a demonstration county for the promotion and application of LED lighting products in the city, and completed the LED lighting renovation in public places by the end of 2014.
Quality control and establishment of quality optimization control system in the process of promotion, how to ensure the quality of LED lighting products? The answer is to establish a quality control system for LED lighting products.
The "Opinions" require that LED lighting products promoted and applied in Quanzhou must comply with the provincial LED lighting related standards, technical specifications and quality control requirements, and recommend LED preferred product suppliers with good reputation, excellent quality and quality control system. release. All LED lighting projects that are financed or invested by state-owned capital or applied for financial incentives and subsidies must use enterprise products listed in the LED Preferred Product Supplier Directory, and prioritize the use of Quanzhou local enterprise products under the same conditions. If the LED energy service company does not purchase the enterprise products of the LED preferred product supplier list as required, once it is found, the corresponding financial subsidy will be cancelled.
Output value target At the end of 2015, LED output value reached 10 billion yuan. Accelerating the development of LED industry is one of the purposes of Quanzhou to promote the common use of LED in public lighting. The "Opinions" proposes to increase the financial resources to support the LED industry, and focus on supporting the research and development of industrial basic and common technologies, technology introduction, technological transformation and transformation of results; at the same time, build a public service platform for LED industry and cultivate a batch of Enterprises with independent innovation and independent intellectual property products.
In addition to encouraging the preferential use of Quanzhou local LED enterprise products, the "Opinions" also encourage and guide Quanzhou LED production enterprises to give priority to the use of basic products such as upstream chips in the city under the same conditions, to reduce production costs faster and accelerate the application and promotion of LED products. Strive to reach the end of 2015, the output value of the LED industry will reach 10 billion yuan, an annual increase of 25 or more.
The finned tube is to improve the heat exchange efficiency. By adding fins on the surface of the heat exchange tube, the outer surface area (or inner surface area) of the heat exchange tube is increased, so as to achieve the purpose of improving the heat exchange efficiency. Such a heat exchange tube . Usually used for heat exchange between liquid and gas.
Finned tube is a heat exchange element. As a heat exchange element, finned tubes usually work under high-temperature flue gas conditions for a long time. For example, the finned tubes usually used in boiler or harsh environments, high temperature and high pressure, and in a corrosive atmosphere. This requires that the finned tubes should have high anti-corrosion properties, Anti-wear properties, lower contact resistance, higher Stability and anti-dusting ability.
There are many types of finned tubes, and new varieties are constantly emerging. According to the classification of processing technology, there are extruded fin tube; high frequency welded finned tubes; rolled formed finned tubes; suit formed finned tubes ; cast finned tubes; tension wound finned tubes; Inserted tubes.
According to the shape of the fins, there are square finned tubes; circular finned tubes; spiral finned tubes; longitudinal finned tubes; corrugated finned tubes; spiral serrated fins Helical Serrated Finned Tubes; pin-shaped finned tubes; integral plate-shaped finned tubes; inner finned tubes.
According to whether the fin material of the finned tube is the same as that of the base tube, it can be divided into: single metal finned tube, bimetallic composite finned tube.
Single metal finned tubes are classified by material into copper finned tubes; aluminum finned tubes; carbon steel finned tubes; stainless steel finned tubes; cast steel finned tubes.
