The level of development of the industry and domestic and international comparative analysis gap - burners, 5t fired boiler and burner systems to control and standardization in foreign countries, the company has successfully developed and promote the use of conventional fuels, including premixed combustion, low NOx combustion technologies, including and unconventional fuels one-piece, split burner products, the largest single power split reach 93MW, monolithic reached 14MW. By using an external flue gas recirculation techniques, internal flue gas recirculation techniques, staged combustion air or fuel staging techniques, flue gas denitrification technology, premixed combustion technology + flameless combustion, the burner nitrogen oxides (of NOX) and boiler nitrogen oxide emissions to a minimum of about 5 / 10mg / m3. Technological development burner of a relatively short history, only five, six years, although from the beginning of imitation but higher than in Europe and other industrialized areas starting point, "five-second" period is entering the period of rise development, product varieties increased rapidly, product quality has greatly improved, especially the steady growth of production and application of non-conventional fuel burners. But it is undeniable, domestic and foreign brands burner there is a certain strength of the gap: ① low NOx combustion with low nitrogen emissions burner domestic enterprises has just begun to address, because there is no boiler manufacturers involved in this industry burner, and more Needless to say, carry out research and development of low NOX burner. ② R & D capabilities in the oil and gas burner and means in Europe and other developed countries, each burner manufacturers have their own R & D test center, and provided strong support for the development of the burner technology. Looking at the top ten manufacturers of our country, in addition to individual enterprise and some simple test bench, most lack a comprehensive, scientific instruments and test equipment as well as related technical professionals in research and development. In a related colleges and universities is also a lack of such research tools. ③ in the production of marketing products overseas burner large burner vendors have implemented mass production, from procurement and manufacturing cost control and marketing and other parts have a very big advantage, resulting in domestic conventional fuel burners competition in the market force is obviously inadequate, domestic burners companies are non-standard products as a breakthrough in the market, it is difficult to form large-scale production.
Burner output should match the rated output of the 5t fired boiler, choose a good shape of the flame, such as length and diameter so as to adapt the furnace structure. The required combustion air is supplied from the root flare fuel gas and air or oil mist uniformly mixed rapidly, to ensure complete combustion.
Beiqi Panther car 6 tons of steam condensing one fuel gas steam 5t fired boiler project has been successfully completed. This series boiler adopt advanced design concepts, using the waste heat of flue gas cascade, with the use of the condenser and the economizer fully absorb the waste heat in the flue gas, the boiler efficiency has been greatly improved.
Acceptance of low nitrogen renovation project management approach gas-fired 5t fired boilers in order to successfully carry out the transformation of the company low-nitrogen, low nitrogen transformation and acceptance process will now be regulated in response to acceptance of work under different circumstances, thus does not affect the progress of the company's overall transformation of low-nitrogen, It is organized as follows. The company low-nitrogen transformation acceptance criteria refer to "Beijing Gas (oil) boiler low nitrogen transformation Yijiangdaibu fund management approach" in low-nitrogen transformation acceptance requirements, low nitrogen transformation of the company and the manufacturers signed contracts for acceptance, and a phased acceptance carried out the way, it is divided into the following four stages: prior to acceptance confirmation from the manufacturer, pre-acceptance, government low nitrogen transformation and acceptance, final completion and acceptance. First, the low nitrogen gas boiler renovation project before pre-acceptance confirmation from the manufacturer to achieve the requirements of the contract 1. The actual standard for this type of project, the next step is direct acceptance process. 2. The actual contract can not reach the required standard (manufacturers to lower the acceptance criteria) for such projects, communication with the manufacturers of xx, re-sign a supplementary agreement or contract, according to a new contract or acceptance protocol standards. 3. The actual contract not up to the required standard (manufacturers do not agree or do not allow the government to reduce the acceptance criteria) for such projects, communication by the xx with the manufacturers, to terminate the contract, non-acceptance. Second, a low nitrogen gas boiler renovation project pre-acceptance satisfy items (1 projects above) pre-acceptance required to start the pre-acceptance operates in the following claims. 1.xx after the company confirmed that manufacturers have reached the standard contract, the company launched an internal pre-acceptance, and notify the relevant Division, Center for Technology Management, Operations Management Center attended. 2. Pre-acceptance of the project can be divided into environmental inspection and acceptance of two parts, the project must meet the acceptance requirements of environmental protection (standards and materials), to enter the next "low nitrogen transformation of government acceptance" stage. Unqualified acceptance content, fill out the on-site rectification notice, rectification, manufacturers, construction units, divisions, technical, operational and other relevant units to sign it by the deadline. 3. If the project environmental impact there is acceptance, boiler and other major security issues, not by pre-acceptance; In addition, pre-acceptance by the environmental protection, engineering, pre-acceptance deadline for correction. 4. In response to these contents rectification notice, by the manufacturer or xx arrange the construction unit to develop corrective plan submitted to the relevant divisions, technical, operational management center knows, in order to determine the final acceptance plan. Third, the low nitrogen gas boiler renovation project government low-nitrogen transformation project through the pre-acceptance and acceptance of environmental protection, and acceptance by the Government Division organized low-nitrogen transformation inspection department, relevant content is organized as follows. 1. A low nitrogen acceptance by the division of the transformation EPA invited, and notifies the acceptance time OA xx, center management technology, operation and management center. 2. The notification by the equipment manufacturers xx company to deal with the EPA project acceptance. 3. Technology Management Center, operation and management center according to the situation, coordination, cooperation division of the Environmental Protection Agency to complete the inspection. 4. acceptance by EPA, proceed to "completion and acceptance of the final" stage. 5. If the EPA does not pass inspection, subject to the opinion of the EPA, the Environmental Protection Agency if given a second chance acceptance, arrange for rectification by the Environmental Protection Agency xx grasp, and to give the exact time of commissioning compliance, and older than the Environmental Protection Agency to give the second acceptance time more than 3 days; EPA if not given a second chance of acceptance, the acceptance consequences borne by the manufacturer and by the execution of the contract with reference to the subsequent procedure. Fourth, low nitrogen gas boiler renovation project completed after final completion and acceptance 1. EPA acceptance, notify the manufacturer xx by the company, the construction unit to start the rectification work. Factory or construction unit for rectification according to plan in accordance with the rectification notice requirements. 2. The respective divisions, technical management center, operation and management of the center to collaborate rectification work, with supervision. 3. After the completion of the rectification project, organized by the xx-related divisions, technical management center, operation and management center participate, final completion and acceptance, to complete the transfer.Free Chat
