This method is at the time of shutdown, when the temperature of the boiler water is reduced to 100 ~ 120 ℃, for drainage. When the water exhausted by the furnace heat, hot air furnace or introduced Microflame point, the inner surfaces of the boiler and drying.
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.
Pressure hot water boiler needs MOT? Pressure hot water boiler is a conventional container is not a pressure vessel, we do not need annual inspection. But it must meet the following three conditions are collectively referred to as a pressure vessel container. (1) is greater than or equal to the operating pressure 0.1mpa (2) is not less than 150mm inner diameter of the container (3) for the working medium gas temperature is higher than the normal boiling point, the liquefied gas or liquid; pressure hot water boiler has the following characteristics: 1 the boiler is very safe. Because the boiler to the atmosphere, no pressure between, which eliminates the possibility of an explosion to a certain extent. 2, may be utilized waste boiler steel, thereby saving steel, simplifying the manufacturing process. China scrapped every year many industrial boilers. The boiler pressure hot water into the boiler can save a lot of steel. Meanwhile, when manufacturing new pressure hot water boiler, due to the reduction of the pressure member, can save a lot of high-quality steel boiler, simplifies the manufacturing process, save manpower, material and financial resources. 3, to simplify the management of pressure hot water boiler. Since the safety pressure hot water boiler, so that the use of pressure hot water boiler, the design, manufacture and installation is simplified, the requirements of the boiler room is reduced. 4, about three in the heating system of the building, the pressurized operating costs and substantially the same pressure hot water boiler hot water boiler. However, pressure hot water boiler heat pump must be selected, so the high cost of using heat pumps, circulating pump head when using high pressure hot water boiler, high energy consumption.
The 30 ton coal fired low pressure package type steam boilers for sale in ZG Boiler has the advantages of wide range of overload adjusting, it can be adjusted to many kinds of coals, thus it is awarded the best design of this kind of boiler.
