Around the city to promote the coal to gas project, the major institutions of the heating system put forward higher requirements. Central Conservatory of Music is available to students and teachers clean, safe, comfortable, energy-efficient heating environment, protect the health of teachers and students, to transform the traditional boiler fired catalog treatment. Praise fast boiler Willie sharp series obtained in the transformation of low nitrogen boiler major institutions in Beijing, the Central Conservatory of Music in late 2017 with the signing of fast boiler boiler purchase contract, ordered six Willy sharp series V6-99, to for the entire school's heating facilities.

Acceptance of low nitrogen renovation project management approach gas-fired boiler fired catalogs 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.

To the end of October 2020 to complete Chaigai coal-fired boiler fired catalogs no longer give financial awards complement.

Further, out of the boiler removal methods include eliminated, an alternative centralized heating boiler, coal gas, coal to electricity, use geothermal, wind, solar, biomass with baghouse, clean coal to burn not including , CWS, anthracite, semi-coke, green coke, crude oil, coal-fired boiler removal must be removed chimney or flue physical cutting, it does not have the complex production conditions. Do not use has been shut down, eliminated waste coal-fired boilers to cash rewards and subsidies. In the process of new coal-fired boilers to switch to natural gas to be synchronized to achieve low nitrogen transformation.

Now on the market most of the boiler fired catalogs to gas, oil, biomass, electricity as the main fuel, coal-fired boilers because of its harmful pollution levels gradually been changed or replaced. In general, no boiler explosion during normal operation, but if it is due to the improper operation of the ignition or operation, it may cause the furnace or tail or secondary combustion flue explosion, resulting in serious danger of impact. In this case the role of "explosion vent" is manifested when the furnace or flue trace knocking occurs, the pressure within the furnace is gradually increased, when a certain value is higher than the pressure relief device can turn on itself through the explosion vent to avoid the risk expansion to ensure the overall safety of boiler and furnace wall, more importantly, it is to protect the safety of the boiler operator. Currently there are blasting boiler membrane and two kinds of swing-proof door.
