water tube water boiler manufacturing

There are hot water tube water boiler manufacturing fuel gas hot water boiler and hot water boiler, when they appear Priming: steam boiler evaporation surface, the water rises together, produce a lot of foam and the phenomenon of fluctuating; boiler event will Priming with water, steam, steam quality decrease, causing overheating structure vibration and water hammer, impact damage to the superheater and safety equipment operation.

The most advantageous use of electric boiler with water softener: electric boiler is equipped with a water softener why, because the electric boiler electric boiler heating equipment, thermal conversion efficiency directly affects the quality of electric boiler. And even the best electric boilers are affected water quality.

Condensing gas boiler water level is too high hazard Some people think that some of the high water level, water condensing gas boiler is not easy, there are security guarantees. In fact, this is a misconception. The water level is too high, steam and humidity increase, poor steam quality, steam equipment will harm production and safety. Industrial boilers, the steam salt also increased, ranging from increased air consumption, ineffective, lower yields; heavy pipes, equipment or even the water hammer occurs. For utility boilers, steam moisture capacity, the steam turbine last stage blades will be erosion, there may appear Priming pot, water shock severe enough to cause harm equipment and personal safety. Therefore, the pot water level should be maintained at ± 50mm as well. Full of water condensing gas boiler accident hazards, mainly caused steam with lots of water, which may cause steam pipe water hammer, reduce steam quality, affecting the normal steam supply, serious cause superheater tube fouling, damage to the steam equipment . In the run condensing gas boiler, the boiler water level higher than the highest level of security and endanger the safe operation of the boiler phenomenon, called full of water accidents. Full of water can be divided into minor accidents and serious water filled full of water two kinds. When the water level exceeds the maximum allowable water level, but below the level of the upper edge of the visible table, although the water level or water table beyond the upper edge of the visible, but after opening the drainage cock water gauge, can quickly see the water level drops, belong slightly with water. The water level exceeds the level of the upper edge of the visible table, when the open drain cocks see when the water level drops in the water table, a serious full of water. When the water deficit in the accident is full, the water level in the water table almost invisible, but full of water and put water accidents can put water released from the water table, and the water can not drain pipe accident put water released from the water table.

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.
