The technology of the fuel divided into three regions: the primary combustion zone (main combustion zone) reducing weakened; fed again in the second combustion zone fuel, it presents reductive; third combustor into the combustion air required for the remaining complete burn-up process, in order to achieve staged combustion of fuel and air. Using this technique, we can reduce NOx emissions from gas-fired industrial condensing boilers supplier more than 70%.
It is understood that in order to successfully promote the transformation and development of traditional coal chemical industry, January 1, 2019, letter to the Office of Henan Province workers released a special action program (hereinafter referred to as the "Program"), to promote pollution prevention campaign of Henan Province, three-year action implementation of the scheme, to speed up the traditional coal chemical industry (ammonia, methanol) industry green transformation, to achieve high-quality development. "Program" details are as follows.
First, the key tasks
1, and strictly control new capacity. Adherence to the red line capacity, traditional coal chemical enterprises prohibit new construction, new capacity expansion projects alone, is strictly prohibited without permission around the building does not meet the requirements of the industrial layout plan of coal chemical project in principle. The province's coal chemical projects and intensive clean-up, but according to the specified time limit has been approved to start construction of the project in principle, to construction, relocation and renovation projects must be upgraded into the base or campus planning. By 2020, the chemical industry out of the fixed bed coal gasifier intermittent exit single set of devices 300,000 tons / year of synthetic ammonia production capacity.
2, increase the relocation and reconstruction efforts. Further promote the densely populated towns of dangerous chemicals production enterprises and urban built-up areas heavily polluting industrial relocation of enterprises, the implementation of an intensive investigation, the establishment of management accounting, according to "a business a policy" during mode classification advance. Priority to promoting the urban area of coal chemical industry relocation, conversion or quit, not in the urban area but not in the business park to gradually move the park, according to the specified execution be discontinued or phased out. Close to exit the business to achieve the "two off three clear" (cut industrial water, electricity, removal of raw materials, products, production equipment), in situ transformation of the company to implement the upgrading of the standard industry benchmark, off-site relocation of enterprises to According to large-scale, modern principles move into the province for involving chemical industry gathering area.
3, Green transformation. Before the end of 2019, coal chemical enterprises fully completed VOCs governance. And comprehensively promote the chemical industry equipment static and dynamic sealing points, storage, handling, waste water systems, unorganized process emissions and non-normal operating conditions and other root causes of remediation. In accordance with national requirements, the timely completion of the coal chemical industry waste discharge permit issued by the work, companies must comply with the behavior of the sewage discharge permit clear conditions, various types of environmental inspection found violations, strictly and severely investigated and dealt with as soon as possible in place.
Second, the organization and implementation
1, roles and responsibilities. Relevant provincial jurisdiction over municipal government on the development of local coal chemical industry restructuring and overall responsibility, strengthen organizational leadership, with local conditions, the development of coal chemical industry restructuring and development program implementation, implementation tasks initiatives. Coal chemical industry is the main responsibility for the implementation of the restructuring and development, to strictly implement the main responsibility for production safety and environmental protection, the implementation of the relocation of the green transformation. Provincial Industry and Information Technology Department, Development and Reform Commission, the ecological environment, the Office of Emergency Management and other provincial departments according to the division of responsibilities, strengthen guidance and improve relevant policies and measures.
2, strictly implement the policy. Comprehensive use of market mechanisms, economic instruments, legal and necessary administrative means to approach, to promote enterprise restructuring and development. Strict implementation of China's industrial policy, strictly enforce the standards of environmental protection, quality, energy consumption, safety and technology. Relocation and reconstruction of urban population centers dangerous chemicals production enterprises and urban built-up area of relocation and reconstruction project focused on heavy polluting industrial enterprises, shall be given support in terms of fiscal policy, tax incentives, financial support, land policies.
3, strengthen supervision and accountability. Strengthen supervision of new capacity alone, without approval of the establishment of Chemical Industry Park, unauthorized implementation does not meet the industrial layout planning requirements of coal chemical projects, in violation of the registration and management of hazardous chemicals and construction projects "three simultaneous" (also designed, constructed, and concurrent use of illegal activities) system, etc., must be severely accountable accountability.
Water tube industrial condensing boilers supplier structure and characteristics (the single vertical water tube boiler drum): a single longitudinal drum furnace wall water tube boiler is divided into light and heavy monolith furnace furnace furnace wall bulk are two, by the vertical drum, water wall tube, and around convection bank set box. Configured features: the central drum longitudinally disposed upper portion of the furnace, and the convection tube sets are disposed on both sides of the waterwall tubes of the furnace, symmetrical, with A similar shape. Smoke vents high temperature flue gas from the furnace into the left rear of the left convection pass forward through the drum from the front end of the transverse flue, the convection pass off to the right person, and then flows back to the front by the economizer, via lead fans and chimneys.
For example industrial condensing boilers supplier price related factors and different price factors Boiler: Boiler price, which is an important aspect of the boiler, particularly in boilers to buy the product, is a specific aspect must be taken into account. So, since this is an important aspect of the boiler, and at the beginning of the article mentioned that the following may wish to get to know to find out, so the site can also learn about the different aspects of the product, and it is also able to broaden their knowledge add some expertise. Household coal-fired boilers, boiler their price? Domestic coal-fired boilers, boiler on its price, mainly to see the heating area, because it is determined. If, heating area is 200 square meters, then the price of the boiler is about a few thousand dollars. Moreover, the boiler is automatic temperature control, then up to 91% in thermal efficiency. 2.15 tons of steam boilers, boiler their price and what about? 15 tons of steam boilers, boiler their price-related factors, mainly fuel type, steam pressure, boiler structure and auxiliary accessories such as these. So, we want these into account, so, in order to make an accurate judgment, and get the right result, then, to choose the right product, to avoid making mistakes.Free Chat
