atmospheric water tube boiler price

The causes of atmospheric water tube boiler price scale boiler water as a medium for heat exchange apparatus A specialty. During operation the surface of furnace and boiler water contact form thick layer of scale, over the years, people have dirt kinds of boiler scale due to the scale have been fully studied, introduced a variety of anti-scaling technology, but still not been completely resolved, while the development of antifouling cleaning technology, as an adjunct to maintain heating surface and the heat transfer surface. So, boiler scale is how did this happen? There are three main reasons: First, the boiler feed water impurities into the boiler, through continuous evaporation and condensation, boiler feed water, concentration of salts continuously increases, the degree of saturation or supersaturation, will be in the boiler metallic surface the precipitated precipitate. Second, with the increase of the boiler water temperature, the solubility of certain salts and inversely proportional to temperature, these salts at elevated temperatures, the solubility is drastically lowered opening formed scale. Third, the interaction of different salts or thermal decomposition to produce a compound difficult to dissolve. Boiler feed water in a continuous process of continuous evaporation, the pure water into steam by the boiler feeding the salt water continuous furnace substance was concentrated, the content of rising. When the boiler feedwater salinity level of saturation or over-saturation, salt materials will precipitate from the water, form a solid precipitate. Adhering a larger portion of their thermal load heating surface to form a hard or soft scale, another portion of the furnace was suspended in water with the boiler water circulating flows. When the heat receiving face of the poor circulation, the flow rate is low, then the deposition of scale on the heating surface to form a secondary, or deposited on the drum should not have high flow rates, a lower collection tank, dirt is formed, with the periodic sewage discharge from the furnace. Thus, generation of scale, in addition to the ingredients and contents of impurities in the boiler water related, but also to a large extent depends on the operating state of the boiler. The larger the water evaporation intensity, the higher circulation rate, the easier it is to generate water circulation easily broken loose precipitate, evaporation of the boiler assembly can reduce the number of scale on a surface. In contrast, evaporation intensity, the lower the cycle rate, the more easy to form scale on the surface of the evaporation boiler.

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.

MODULAR hot water atmospheric water tube boiler price, based on user demand and a preset load size, the number of small boilers can operate independently of the cell assembly module into the boiler, through the outer chamber temperature, for checking return check check check temperature change See test measurement and calculation, computer-controlled system may control each of a module, the module automatically adjusts the number of start and stop the output to the actual needs of the whole story calorie heat load match, and each module can be secured at the beginning and end of combustion to maintain good conditions phenomenon and thus achieve overall efficient operation of the boiler.

Objective analysis: strengths and weaknesses gas atmospheric water tube boiler price: increasing energy crisis and the growing environmental pressures, the Chinese government also introduced a series of laws and regulations on the promotion of energy conservation and emissions, encouraging the use of new energy and other areas, gas boilers should be shipped together, breaking the previous coal-fired boiler "thriving" situation.
